Most modules out there are either antiquated, i.e. they do not support latest cookie rfc6265 , or they focus only on http client side. For example, Apache2::Cookie does not work well in decoding cookies, and Cookie::Baker "Set-Cookie" timestamp format is wrong. They use Mon-09-Jan 2020 12:17:30 GMT where it should be, as per rfc 6265 Mon, 09 Jan 2020 12:17:30 GMT Also APR::Request::Cookie and Apache2::Cookie which is a wrapper around APR::Request::Cookie return a cookie object that returns the value of the cookie upon stringification instead of the full "Set-Cookie" parameters. Clearly they designed it with a bias leaned toward collecting cookies from the browser. This module supports modperl and uses a Apache2::RequestRec if provided, or can use package objects that implement similar interface as HTTP::Request and HTTP::Response, or if none of those above are available or provided, this module returns its results as a string. This module is also compatible with LWP::UserAgent, so you can use like this: use LWP::UserAgent; use Cookie::Jar; my $ua = LWP::UserAgent->new( cookie_jar => Cookie::Jar->new ); It is also compatible with HTTP::Promise, such as: use HTTP::Promise; my $ua = HTTP::Promise->new( cookie_jar => Cookie::Jar->new ); This module does not die upon error, but instead returns "undef" and sets an error, so you should always check the return value of a method. METHODS new This initiates the package and takes the following parameters: * "request" This is an optional parameter to provide a Apache2::RequestRec object. When provided, it will be used in various methods to get or set cookies from or onto http headers. package MyApacheHandler; use Apache2::Request (); use Cookie::Jar; sub handler : method { my( $class, $r ) = @_; my $jar = Cookie::Jar->new( $r ); # Load cookies; $jar->fetch; $r->log_error( "$class: Found ", $jar->repo->length, " cookies." ); $jar->add( name => 'session', value => 'lang=en-GB', path => '/', secure => 1, same_site => 'Lax', ); # Will use Apache2::RequestRec object to set the Set-Cookie headers $jar->add_response_header || do { $r->log_reason( "Unable to add Set-Cookie to response header: ", $jar->error ); return( Apache2::Const::HTTP_INTERNAL_SERVER_ERROR ); }; # Do some more computing return( Apache2::Const::OK ); } * "debug" Optional. If set with a positive integer, this will activate verbose debugging message add Provided with an hash or hash reference of cookie parameters (see Cookie) and this will create a new cookie and add it to the cookie repository. Alternatively, you can also provide directly an existing cookie object my $c = $jar->add( $cookie_object ) || die( $jar->error ); add_cookie_header This is an alias for "add_request_header" for backward compatibility with HTTP::Cookies add_request_header Provided with a request object, such as, but not limited to HTTP::Request and this will add all relevant cookies in the repository into the "Cookie" http request header. The object method needs to have the "header" method in order to get, or set the "Cookie" or "Set-Cookie" headers and the "uri" method. As long as the object provided supports the "uri" and "header" method, you can provide any class of object you want. Please refer to the rfc6265 for more information on the applicable rule when adding cookies to the outgoing request header. Basically, it will add, for a given domain, first all cookies whose path is longest and at path equivalent, the cookie creation date is used, with the earliest first. Cookies who have expired are not sent, and there can be cookies bearing the same name for the same domain in different paths. add_response_header # Adding cookie to the repository $jar->add( name => 'session', value => 'lang=en-GB', path => '/', secure => 1, same_site => 'Lax', ) || die( $jar->error ); # then placing it onto the response header $jar->add_response_header; This is the alter ego to "add_request_header", in that it performs the equivalent function, but for the server side. You can optionally provide, as unique argument, an object, such as but not limited to, HTTP::Response, as long as that class supports the "header" method Alternatively, if an Apache object has been set upon object instantiation or later using the "request" method, then it will be used to set the outgoing "Set-Cookie" headers (there is one for every cookie sent). If no response, nor Apache2 object were set, then this will simply return a list of "Set-Cookie" in list context, or a string of possibly multiline "Set-Cookie" headers, or an empty string if there is no cookie found to be sent. Be careful not to do the following: # get cookies sent by the http client $jar->fetch || die( $jar->error ); # set the response headers with the cookies from our repository $jar->add_response_header; Why? Well, because "fetch" retrieves the cookies sent by the http client and store them into the repository. However, cookies sent by the http client only contain the cookie name and value, such as: GET /my/path/ HTTP/1.1 Host: www.example.org Cookie: session_token=eyJleHAiOjE2MzYwNzEwMzksImFsZyI6IkhTMjU2In0.eyJqdGkiOiJkMDg2Zjk0OS1mYWJmLTRiMzgtOTE1ZC1hMDJkNzM0Y2ZmNzAiLCJmaXJzdF9uYW1lIjoiSm9obiIsImlhdCI6MTYzNTk4NDYzOSwiYXpwIjoiNGQ0YWFiYWQtYmJiMy00ODgwLThlM2ItNTA0OWMwZTczNjBlIiwiaXNzIjoiaHR0cHM6Ly9hcGkuZXhhbXBsZS5jb20iLCJlbWFpbCI6ImpvaG4uZG9lQGV4YW1wbGUuY29tIiwibGFzdF9uYW1lIjoiRG9lIiwic3ViIjoiYXV0aHxlNzg5OTgyMi0wYzlkLTQyODctYjc4Ni02NTE3MjkyYTVlODIiLCJjbGllbnRfaWQiOiJiZTI3N2VkYi01MDgzLTRjMWEtYTM4MC03Y2ZhMTc5YzA2ZWQiLCJleHAiOjE2MzYwNzEwMzksImF1ZCI6IjRkNGFhYmFkLWJiYjMtNDg4MC04ZTNiLTUwNDljMGU3MzYwZSJ9.VSiSkGIh41xXIVKn9B6qGjfzcLlnJAZ9jGOPVgXASp0; csrf_token=9849724969dbcffd48c074b894c8fbda14610dc0ae62fac0f78b2aa091216e0b.1635825594; site_prefs=lang%3Den-GB As you can see, 3 cookies were sent: "session_token", "csrf_token" and "site_prefs" So, when "fetch" creates an object for each one and store them, those cookies have no "path" value and no other attribute, and when "add_response_header" is then called, it stringifies the cookies and create a "Set-Cookie" header for each one, but only with their value and no other attribute. The http client, when receiving those cookies will derive the missing cookie path to be "/my/path", i.e. the current uri path, and will create a duplicate cookie from the previously stored cookie with the same name for that host, but that had the path set to "/" So you can create a repository and use it to store the cookies sent by the http client using "fetch", but in preparation of the server response, either use a separate repository with, for example, "my $jar_out = Cookie::Jar->new" or use "set" which will not add the cookie to the repository, but rather only set the "Set-Cookie" header for that cookie. # Add Set-Cookie header for that cookie, but do not add cookie to repository $jar->set( $cookie_object ); algo String. Sets or gets the algorithm to use when loading or saving the cookie jar. autosave Boolean. Sets or gets the boolean value for automatically saving the cookie jar to the given file specified with "file" delete Given a cookie name, an optional host and optional path or a Cookie object, and this will remove it from the cookie repository. It returns an array object upon success, or "undef" in perlfunc and sets an error. Note that the array object may be empty. However, this will NOT remove it from the web browser by sending a Set-Cookie header. For that, you might want to look at the "elapse" in Cookie method. It returns an array object of cookie objects removed. my $arr = $jar->delete( 'my-cookie' ); # alternatively my $arr = $jar->delete( 'my-cookie' => 'www.example.org' ); # or my $arr = $jar->delete( $my_cookie_object ); printf( "%d cookie(s) removed.\n", $arr->length ); print( "Cookie value removed was: ", $arr->first->value, "\n" ); If you are interested in telling the http client to remove all your cookies, you can set the "Clear-Site-Data" header: Clear-Site-Data: "cookies" You can instruct the http client to remove other data like local storage: Clear-Site-Data: "cookies", "cache", "storage", "executionContexts" Although this is widely supported, there is no guarantee the http client will actually comply with this request. See Mozilla documentation for more information. do Provided with an anonymous code or reference to a subroutine, and this will call that code for every cookie in the repository, passing it the cookie object as the sole argument. Also, that cookie object is accessible using $_. If the code return "undef", it will end the loop, and if the code returns true, this will have the current cookie object added to an array object returned upon completion of the loop. my $found = $jar->do(sub { # Part of the path if( index( $path, $_->path ) == 0 ) { return(1); } return(0); }); print( "Found cookies: ", $found->map(sub{$_->name})->join( ',' ), "\n" ); encrypt Boolean. Sets or gets the boolean value for whether to encrypt or not the cookie jar when saving it, or whether to decrypt it when loading cookies from it. This defaults to false. exists Given a cookie name, this will check if it exists. It returns 1 if it does, or 0 if it does not. extract Provided with a response object, such as, but not limited to HTTP::Response, and this will retrieve any cookie sent from the remote server, parse them and add their respective to the repository. As per the rfc6265, section 5.3.11 specifications if there are duplicate cookies for the same domain and path, only the last one will be retained. If the cookie received does not contain any "Domain" specification, then, in line with rfc6265 specifications, it will take the root of the current domain as the default domain value. Since finding out what is the root for a domain name is a non-trivial exercise, this method relies on Cookie::Domain. extract_cookies This is an alias for "extract" for backward compatibility with HTTP::Cookies extract_one This method takes a cookie string, which can be found in the "Set-Cookie" header, parse it, and returns a Cookie object if successful, or sets an error and return "undef" or an empty list depending on the context. It also takes an hash or hash reference of options. The following options are supported: * "host" If provided, it will be used to find out the host's root domain, and to set the cookie object "domain" property if none is specified in the cookie string. * "path" If provided, it will be used to set the cookie object "path" property. * "port" If provided, it will be used to set the cookie object "port" property. fetch This method does the equivalent of "extract", but for the server. It retrieves all possible cookies from the http request received from the web browser. It takes an optional hash or hash reference of parameters, such as "host". If it is not provided, the value set with "host" is used instead. If the parameter "request" containing an http request object, such as, but not limited to HTTP::Request, is provided, it will use it to get the "Cookie" header value. The object method needs to have the "header" method in order to get, or set the "Cookie" or "Set-Cookie" headers. Alternatively, if a value for "request" has been set, it will use it to get the "Cookie" header value from Apache modperl. You can also provide the "Cookie" string to parse by providing the "string" option to this method. $jar->fetch( string => q{foo=bar; site_prefs=lang%3Den-GB} ) || die( $jar->error ); Ultimately, if none of those are available, it will use the environment variable "HTTP_COOKIE" If the option "store" is true (by default it is true), this method will add the fetched cookies to the repository. It returns an hash reference of cookie key => cookie object A cookie key is made of the host (possibly empty), the path and the cookie name separated by ";" # Cookies added to the repository $jar->fetch || die( $jar->error ); # Cookies returned, but NOT added to the repository my $cookies = $jar->fetch || die( $jar->error ); file Sets or gets the file path to the cookie jar file. If provided upon instantiation, and if the file exists on the filesystem and is not empty, "Cookie::Jar" will load all the cookies from it. If "autosave" is set to a true, "Cookie::Jar" will automatically save all cookies to the specified cookie jar file, possibly encrypting it if "algo" and "secret" are set. get Given a cookie name, an optional host and an optional path, this will retrieve its corresponding cookie object and return it. If not found, it will try to return a value with just the cookie name. If nothing is found, this will return and empty list in list context or "undef" in scalar context. You can "get" multiple cookie object and this method will return a list in list context and the first cookie object found in scalar context. # Wrong, an undefined returned value here only means there is no such cookie my $c = $jar->get( 'my-cookie' ); die( $jar->error ) if( !defined( $c ) ); # Correct my $c = $jar->get( 'my-cookie' ) || die( "No cookie my-cookie found\n" ); # Possibly get multiple cookie object for the same name my @cookies = $jar->get( 'my_same_name' ) || die( "No cookies my_same_name found\n" ); # or my @cookies = $jar->get( 'my_same_name' => 'www.example.org', '/private' ) || die( "No cookies my_same_name found\n" ); get_by_domain Provided with a host and an optional hash or hash reference of parameters, and this returns an array object of cookie objects matching the domain specified. If a "sort" parameter has been provided and its value is true, this will sort the cookies by path alphabetically. If the sort value exists, but is false, this will sort the cookies by path but in a reverse alphabetical order. By default, the cookies are sorted. host Sets or gets the default host. This is especially useful for cookies repository used on the server side. key Provided with a cookie name and an optional host and this returns a key used to add an entry in the hash repository. If no host is provided, the key is just the cookie, otherwise the resulting key is the cookie name and host separated just by ";" You should not need to use this method as it is used internally only. length Read-only. Returns the size of the Cookie repository as a number object load $jar->load( '/home/joe/cookies.json' ) || die( $jar->error ); # or loading cookies from encrypted file $jar->load( '/home/joe/cookies_encrypted.json', { decrypt => 1, key => $key, iv => $iv, algo => 'AES' }) || die( $jar->error ); Give a json cookie file, and an hash or hash reference of options, and this will load its data into the repository. If there are duplicates (same cookie name and host), the latest one added takes precedence, as per the rfc6265 specifications. Supported options are: * "algo" string Algorithm to use to decrypt the cookie file. It can be any of AES, Anubis, Blowfish, CAST5, Camellia, DES, DES_EDE, KASUMI, Khazad, MULTI2, Noekeon, RC2, RC5, RC6, SAFERP, SAFER_K128, SAFER_K64, SAFER_SK128, SAFER_SK64, SEED, Skipjack, Twofish, XTEA, IDEA, Serpent or simply any for which there exists Crypt::Cipher:: * "decrypt" boolean Must be set to true to enable decryption. * "iv" string Set the Initialisation Vector used for file encryption and decryption. This must be the same value used for encryption. See "save" * "key" string Set the encryption key used to decrypt the cookies file. The key must be the same one used to encrypt the file. See "save" "load" returns the current object upon success and "undef" and sets an error upon error. load_as_lwp $jar->load_as_lwp( '/home/joe/cookies_lwp.txt' ) || die( "Unable to load cookies from file: ", $jar->error ); # or loading an encrypted file $jar->load_as_lwp( '/home/joe/cookies_encrypted_lwp.txt', { encrypt => 1, key => $key, iv => $iv, algo => 'AES', }) || die( $jar->error ); Given a file path to an LWP-style cookie file (see below a snapshot of what it looks like), and an hash or hash reference of options, and this method will read the cookies from the file and add them to our repository, possibly overwriting previous cookies with the same name and domain name. The supported options are the same as for "load" LWP-style cookie files are ancient, and barely used anymore, but no matter; if you need to load cookies from such file, it looks like this: #LWP-Cookies-1.0 Set-Cookie3: cookie1=value1; domain=example.com; path=; path_spec; secure; version=2 Set-Cookie3: cookie2=value2; domain=api.example.com; path=; path_spec; secure; version=2 Set-Cookie3: cookie3=value3; domain=img.example.com; path=; path_spec; secure; version=2 It returns the current object upon success, or "undef" and sets an error upon error. load_as_mozilla $jar->load_as_mozilla( '/home/joe/cookies.sqlite' ) || die( "Unable to load cookies from mozilla cookies.sqlite file: ", $jar->error ); Given a file path to a mozilla SQLite database file, and an hash or hash reference of options, and this method will attempt to read the cookies from the SQLite database file and add them to our repository, possibly overwriting previous cookies with the same name and domain name. To read the SQLite database file, this will try first to load DBI and DBD::SQLite and use them if they are available, otherwise it will resort to using the "sqlite3" binary if it can find it, using "which" in File::Which If none of those 2 methods succeeded, it will return "undef" with an error Note that contrary to other loading method, this method does not support encryption. It returns the current object upon success, or "undef" and sets an error upon error. Supported options are: * "use_dbi" Boolean. If true, this will require the use of DBI and DBD::SQLite and if it cannot load them, it will return an error without trying to alternatively use the "sqlite3" binary. Default to false. * "sqlite" String. The file path to a "sqlite3" binary. If the file path does not exist, or is lacking sufficient permission, this will return an error. If it is not provided, and using DBI and DBD::SQLite failed, it will try to find the "sqlite3" using "which" in File::Which load_as_netscape $jar->save_as_netscape( '/home/joe/cookies_netscape.txt' ) || die( "Unable to save cookies file: ", $jar->error ); # or saving as an encrypted file $jar->save_as_netscape( '/home/joe/cookies_encrypted_netscape.txt', { encrypt => 1, key => $key, iv => $iv, algo => 'AES', }) || die( $jar->error ); Given a file path to a Netscape-style cookie file, and this method will read cookies from the file and add them to our repository, possibly overwriting previous cookies with the same name and domain name. It returns the current object upon success, or "undef" and sets an error upon error. make Provided with some parameters and this will instantiate a new Cookie object with those parameters and return the new object. This does not add the newly created cookie object to the cookies repository. For a list of supported parameters, refer to the Cookie documentation # Make an encrypted cookie use Bytes::Random::Secure (); my $c = $jar->make( name => 'session', value => $secret_value, path => '/', secure => 1, http_only => 1, same_site => 'Lax', key => Bytes::Random::Secure::random_bytes(32), algo => $algo, encrypt => 1, ) || die( $jar->error ); # or as an hash reference of parameters my $c = $jar->make({ name => 'session', value => $secret_value, path => '/', secure => 1, http_only => 1, same_site => 'Lax', key => Bytes::Random::Secure::random_bytes(32), algo => $algo, encrypt => 1, }) || die( $jar->error ); merge Provided with another Cookie::Jar object, or at least an object that supports the "do" method, which takes an anonymous code as argument, and that calls that code passing it each cookie object found in the alternate repository, and this method will add all those cookies in the alternate repository into the current repository. $jar->merge( $other_jar ) || die( $jar->error ); If the cookie objects passed to the anonymous code in this method, are not Cookie object, then at least they must support the methods "name", "value", "domain", "path", "port", "secure", "max_age", "secure", "same_site" and , "http_only" This method also takes an hash or hash reference of options: * "die" boolean If true, the anonymous code passed to the "do" method called, will die upon error. Default to false. By default, if an error occurs, "undef" is returned and the error is set. * "overwrite" boolean If true, when an existing cookie is found it will be overwritten by the new one. Default to false. use Nice::Try; try { $jar->merge( $other_jar, die => 1, overwrite => 1 ); } catch( $e ) { die( "Failed to merge cookies repository: $e\n" ); } Upon success this will return the current object, and if there was an error, this returns "undef" in perlfunc and sets an error parse This method is used by "fetch" to parse cookies sent by http client. Parsing is much simpler than for http client receiving cookies from server. It takes the raw "Cookie" string sent by the http client, and returns an hash reference (possibly empty) of cookie name to cookie value pairs. my $cookies = $jar->parse( 'foo=bar; site_prefs=lang%3Den-GB' ); # You can safely do as well: my $cookies = $jar->parse( '' ); purge Thise takes no argument and will remove from the repository all cookies that have expired. A cookie that has expired is a Cookie that has its "expires" property set and whose value is in the past. This returns an array object of all the cookies thus removed. my $all = $jar->purge; printf( "Cookie(s) removed were: %s\n", $all->map(sub{ $_->name })->join( ',' ) ); # or printf( "%d cookie(s) removed from our repository.\n", $jar->purge->length ); replace Provided with a Cookie object, and an optional other Cookie object, and this method will replace the former cookie provided in the second parameter with the new one provided in the first parameter. If only one parameter is provided, the cookies to be replaced will be derived from the replacement cookie's properties, namely: "name", "domain" and "path" It returns an array object of cookie objects replaced upon success, or "undef" and set an error upon error. repo Set or get the array object used as the cookie jar repository. printf( "%d cookies found\n", $jar->repo->length ); request Set or get the Apache2::RequestRec object. This object is used to set the "Set-Cookie" header within modperl. save $jar->save( '/home/joe/cookies.json' ) || die( "Failed to save cookies: ", $jar->error ); # or saving the cookies file encrypted $jar->save( '/home/joe/cookies_encrypted.json', { encrypt => 1, key => $key, iv => $iv, algo => 'AES', }) || die( $jar->error ); Provided with a file, and an hash or hash reference of options, and this will save the repository of cookies as json data. The hash saved to file contains 2 top properties: "updated_on" containing the last update date and "cookies" containing an hash of cookie name to cookie properties pairs. It returns the current object. If an error occurred, it will return "undef" and set an error Supported options are: * "algo" string Algorithm to use to encrypt the cookie file. It can be any of AES, Anubis, Blowfish, CAST5, Camellia, DES, DES_EDE, KASUMI, Khazad, MULTI2, Noekeon, RC2, RC5, RC6, SAFERP, SAFER_K128, SAFER_K64, SAFER_SK128, SAFER_SK64, SEED, Skipjack, Twofish, XTEA, IDEA, Serpent or simply any for which there exists Crypt::Cipher:: * "encrypt" boolean Must be set to true to enable encryption. * "iv" string Set the Initialisation Vector used for file encryption. If you do not provide one, it will be automatically generated. If you want to provide your own, make sure the size meets the encryption algorithm size requirement. You also need to keep this to decrypt the cookies file. To find the right size for the Initialisation Vector, for example for algorithm "AES", you could do: perl -MCrypt::Cipher::AES -lE 'say Crypt::Cipher::AES->blocksize' which would yield 16 * "key" string Set the encryption key used to encrypt the cookies file. The key must be the same one used to decrypt the file and must have a size big enough to satisfy the encryption algorithm requirement, which you can check with, say for "AES": perl -MCrypt::Cipher::AES -lE 'say Crypt::Cipher::AES->keysize' In this case, it will yield 32. Replace above "AES", by whatever algorithm you have chosen. perl -MCrypt::Cipher::Blowfish -lE 'say Crypt::Cipher::Blowfish->keysize' would yield 56 for "Blowfish" You can use "random_bytes" in Bytes::Random::Secure to generate a random key: # will generate a 32 bytes-long key my $key = Bytes::Random::Secure::random_bytes(32); When encrypting the cookies file, this method will encode the encrypted data in base64 before saving it to file. save_as_lwp $jar->save_as_lwp( '/home/joe/cookies_lwp.txt' ) || die( "Unable to save cookies file: ", $jar->error ); # or saving as an encrypted file $jar->save_as_lwp( '/home/joe/cookies_encrypted_lwp.txt', { encrypt => 1, key => $key, iv => $iv, algo => 'AES', }) || die( $jar->error ); Provided with a file, and an hash or hash reference of options, and this save the cookies repository as a LWP-style data. The supported options are the same as for "save" It returns the current object. If an error occurred, it will return "undef" and set an error save_as_mozilla $jar->save_as_mozilla( '/home/joe/cookies.sqlite' ) || die( "Unable to save cookies as mozilla SQLite database: ", $jar->error ); # or $jar->save_as_mozilla( '/home/joe/cookies.sqlite', { # force use of DBI/DBD::SQLite use_dbi => 1, # or specify the path of the sqlite3 binary # sqlite => '/some/where/sqlite3', # Enable logging of SQL queries maybe? # log_sql => '/some/where/sql.log', # Overwrite previous data overwrite => 1, # abort if an error occurred rollback => 1, }) || die( "Unable to save cookies as mozilla SQLite database: ", $jar->error ); Provided with a file path to a SQLite database and this saves the cookies repository as a mozilla SQLite database. The structure of the mozilla SQLite database is: CREATE TABLE moz_cookies( id INTEGER PRIMARY KEY, originAttributes TEXT NOT NULL DEFAULT '', name TEXT, value TEXT, host TEXT, path TEXT, expiry INTEGER, lastAccessed INTEGER, creationTime INTEGER, isSecure INTEGER, isHttpOnly INTEGER, inBrowserElement INTEGER DEFAULT 0, sameSite INTEGER DEFAULT 0, rawSameSite INTEGER DEFAULT 0, schemeMap INTEGER DEFAULT 0, CONSTRAINT moz_uniqueid UNIQUE(name, host, path, originAttributes) ); This method will attempt loading DBI and DBD::SQLite, and if it fails, it will alternatively try to use the "sqlite3" binary. Note that, contrary to other save methods, this method does not allow encrypting the SQLite database. It returns the current object. If an error occurred, it will return "undef" and set an error Supported options are: * "log_sql" String. This specifies a file name that will be opened in append mode and to which the SQL statements issued will be logged. * "overwrite" Boolean. If true, this will overwrite any existing data if the specified SQLite database file already exists. And if false, this will issue sql queries to perform upsert if the SQLite version is greater or equal to 3.24.0 (2018-06-04), or otherwise it will issue INSERT OR REPLACE queries. Default false. * "rollback" Boolean. If true, this will cancel, i.e. rollback, any change mad to the SQLite database upon error, otherwise, any change made will be kept up to the point of when the error occurred. Default to false. * "skip_discard" Boolean. If true, this will not save cookies that have been marked as being discarded, such as session cookies. Default false. * "skip_expired" Boolean. If true, this will not save the cookies that have already expired. Default false. * "sqlite" String. The file path to a "sqlite3" binary. If the file path does not exist, or is lacking sufficient permission, this will return an error. If it is not provided, and using DBI and DBD::SQLite failed, it will try to find the "sqlite3" using "which" in File::Which * "use_dbi" Boolean. Requires the use of DBI and DBD::SQLite and it will return an error if those are not installed. If you want to let this method try also to use "sqlite3" binary if necessary, then do not set this option. save_as_netscape Provided with a file and this saves the cookies repository as a Netscape-style data. It returns the current object. If an error occurred, it will return "undef" and set an error scan This is an alias for "do" secret String. Sets or gets the secret string to use for decrypting or encrypting the cookie jar. This is used in conjonction with "file", "encrypt" and "algo" set Given a cookie object, and an optional hash or hash reference of parameters, and this will add the cookie to the outgoing http headers using the "Set-Cookie" http header. To do so, it uses the Apache2::RequestRec value set in "request", if any, or a HTTP::Response compatible response object provided with the "response" parameter. $jar->set( $c, response => $http_response_object ) || die( $jar->error ); Ultimately if none of those two are provided it returns the "Set-Cookie" header as a string. # Returns something like: # Set-Cookie: my-cookie=somevalue print( STDOUT $jar->set( $c ), "\015\012" ); Unless the latter, this method returns the current object. type String. Sets or gets the cookie jar file format type. The supported formats are: "json", "lwp" and "netscape" IMPORTING COOKIES To import cookies, you can either use the methods scan from HTTP::Cookies, such as: use Cookie::Jar; use HTTP::Cookies; my $jar = Cookie::Jar->new; my $old = HTTP::Cookies->new; $old->load( '/home/joe/old_cookies_file.txt' ); my @keys = qw( version key val path domain port path_spec secure expires discard hash ); $old->scan(sub { my @values = @_; my $ref = {}; @$ref{ @keys } = @values; my $c = Cookie->new; $c->apply( $ref ) || die( $c->error ); $jar->add( $c ); }); printf( "%d cookies now in our repository.\n", $jar->repo->length ); or you could also load a cookie file. Cookie::Jar supports LWP format and old Netscape format: $jar->load_as_lwp( '/home/joe/lwp_cookies.txt' ); $jar->load_as_netscape( '/home/joe/netscape_cookies.txt' ); And of course, if you are using Cookie::Jar json cookies file, you can import them with: $jar->load( '/home/joe/cookies.json' ); ENCRYPTION This package supports encryption and decryption of cookies file, and also the cookies values themselve. See methods "save" and "load" for encryption options and the Cookie package for options to encrypt or sign cookies value. INSTALLATION As usual, to install this module, you can do: perl Makefile.PL make make test sudo make install If you have Apache/modperl2 installed, this will also prepare the Makefile and run test under modperl. The Makefile.PL tries hard to find your Apache configuration, but you can give it a hand by specifying some command line parameters. See Apache::TestMM for available parameters or you can type on the command line: perl -MApache::TestConfig -le 'Apache::TestConfig::usage()' For example: perl Makefile.PL -apxs /usr/bin/apxs -port 1234 # which will also set the path to httpd_conf, otherwise perl Makefile.PL -httpd_conf /etc/apache2/apache2.conf # then make make test sudo make install See also modperl testing documentation But, if for some reason, you do not want to perform the mod_perl tests, you can use "NO_MOD_PERL=1" when calling "perl Makefile.PL", such as: NO_MOD_PERL=1 perl Makefile.PL make make test sudo make install AUTHOR Jacques Deguest SEE ALSO Cookie, Cookie::Domain, Apache2::Cookies, APR::Request::Cookie, Cookie::Baker Latest tentative version of the cookie standard Mozilla documentation on Set-Cookie Information on double submit cookies COPYRIGHT & LICENSE Copyright (c) 2019-2019 DEGUEST Pte.
