258 | =head1 DESCRIPTION | ||||
259 | |||||
260 | CGI::Cookie is an interface to HTTP/1.1 cookies, a mechanism | ||||
261 | that allows Web servers to store persistent information on | ||||
262 | the browser's side of the connection. Although CGI::Cookie is | ||||
263 | intended to be used in conjunction with CGI.pm (and is in fact used by | ||||
264 | it internally), you can use this module independently. | ||||
265 | |||||
266 | For full information on cookies see | ||||
267 | |||||
268 | https://tools.ietf.org/html/rfc6265 | ||||
269 | |||||
270 | =head1 USING CGI::Cookie | ||||
271 | |||||
272 | CGI::Cookie is object oriented. Each cookie object has a name and a | ||||
273 | value. The name is any scalar value. The value is any scalar or | ||||
274 | array value (associative arrays are also allowed). Cookies also have | ||||
275 | several optional attributes, including: | ||||
276 | |||||
277 | =over 4 | ||||
278 | |||||
279 | =item B<1. expiration date> | ||||
280 | |||||
281 | The expiration date tells the browser how long to hang on to the | ||||
282 | cookie. If the cookie specifies an expiration date in the future, the | ||||
283 | browser will store the cookie information in a disk file and return it | ||||
284 | to the server every time the user reconnects (until the expiration | ||||
285 | date is reached). If the cookie species an expiration date in the | ||||
286 | past, the browser will remove the cookie from the disk file. If the | ||||
287 | expiration date is not specified, the cookie will persist only until | ||||
288 | the user quits the browser. | ||||
289 | |||||
290 | =item B<2. domain> | ||||
291 | |||||
292 | This is a partial or complete domain name for which the cookie is | ||||
293 | valid. The browser will return the cookie to any host that matches | ||||
294 | the partial domain name. For example, if you specify a domain name | ||||
295 | of ".capricorn.com", then the browser will return the cookie to | ||||
296 | Web servers running on any of the machines "www.capricorn.com", | ||||
297 | "ftp.capricorn.com", "feckless.capricorn.com", etc. Domain names | ||||
298 | must contain at least two periods to prevent attempts to match | ||||
299 | on top level domains like ".edu". If no domain is specified, then | ||||
300 | the browser will only return the cookie to servers on the host the | ||||
301 | cookie originated from. | ||||
302 | |||||
303 | =item B<3. path> | ||||
304 | |||||
305 | If you provide a cookie path attribute, the browser will check it | ||||
306 | against your script's URL before returning the cookie. For example, | ||||
307 | if you specify the path "/cgi-bin", then the cookie will be returned | ||||
308 | to each of the scripts "/cgi-bin/tally.pl", "/cgi-bin/order.pl", and | ||||
309 | "/cgi-bin/customer_service/complain.pl", but not to the script | ||||
310 | "/cgi-private/site_admin.pl". By default, the path is set to "/", so | ||||
311 | that all scripts at your site will receive the cookie. | ||||
312 | |||||
313 | =item B<4. secure flag> | ||||
314 | |||||
315 | If the "secure" attribute is set, the cookie will only be sent to your | ||||
316 | script if the CGI request is occurring on a secure channel, such as SSL. | ||||
317 | |||||
318 | =item B<5. httponly flag> | ||||
319 | |||||
320 | If the "httponly" attribute is set, the cookie will only be accessible | ||||
321 | through HTTP Requests. This cookie will be inaccessible via JavaScript | ||||
322 | (to prevent XSS attacks). | ||||
323 | |||||
324 | This feature is supported by nearly all modern browsers. | ||||

333 | =head2 Creating New Cookies | ||||
334 | |||||
335 | my $c = CGI::Cookie->new(-name => 'foo', | ||||
336 | -value => 'bar', | ||||
337 | -expires => '+3M', | ||||
338 | '-max-age' => '+3M', | ||||
339 | -domain => '.capricorn.com', | ||||
340 | -path => '/cgi-bin/database', | ||||
341 | -secure => 1 | ||||
342 | ); | ||||
343 | |||||
344 | Create cookies from scratch with the B<new> method. The B<-name> and | ||||
345 | B<-value> parameters are required. The name must be a scalar value. | ||||
346 | The value can be a scalar, an array reference, or a hash reference. | ||||
347 | (At some point in the future cookies will support one of the Perl | ||||
348 | object serialization protocols for full generality). | ||||
349 | |||||
350 | B<-expires> accepts any of the relative or absolute date formats | ||||
351 | recognized by CGI.pm, for example "+3M" for three months in the | ||||
352 | future. See CGI.pm's documentation for details. | ||||
353 | |||||
354 | B<-max-age> accepts the same data formats as B<< -expires >>, but sets a | ||||
355 | relative value instead of an absolute like B<< -expires >>. This is intended to be | ||||
356 | more secure since a clock could be changed to fake an absolute time. In | ||||
357 | practice, as of 2011, C<< -max-age >> still does not enjoy the widespread support | ||||
358 | that C<< -expires >> has. You can set both, and browsers that support | ||||
359 | C<< -max-age >> should ignore the C<< Expires >> header. The drawback | ||||
360 | to this approach is the bit of bandwidth for sending an extra header on each cookie. | ||||
361 | |||||
362 | B<-domain> points to a domain name or to a fully qualified host name. | ||||
363 | If not specified, the cookie will be returned only to the Web server | ||||
364 | that created it. | ||||
365 | |||||
366 | B<-path> points to a partial URL on the current server. The cookie | ||||
367 | will be returned to all URLs beginning with the specified path. If | ||||
368 | not specified, it defaults to '/', which returns the cookie to all | ||||
369 | pages at your site. | ||||
370 | |||||
371 | B<-secure> if set to a true value instructs the browser to return the | ||||
372 | cookie only when a cryptographic protocol is in use. | ||||
373 | |||||
374 | B<-httponly> if set to a true value, the cookie will not be accessible | ||||
375 | via JavaScript. | ||||
376 | |||||
377 | For compatibility with Apache::Cookie, you may optionally pass in | ||||
378 | a mod_perl request object as the first argument to C<new()>. It will | ||||
379 | simply be ignored: | ||||
380 | |||||
381 | my $c = CGI::Cookie->new($r, | ||||
382 | -name => 'foo', | ||||
383 | -value => ['bar','baz']); | ||||
384 | |||||
385 | =head2 Sending the Cookie to the Browser | ||||
386 | |||||
387 | The simplest way to send a cookie to the browser is by calling the bake() | ||||
388 | method: | ||||
389 | |||||
390 | $c->bake; | ||||
391 | |||||
392 | This will print the Set-Cookie HTTP header to STDOUT using CGI.pm. CGI.pm | ||||
393 | will be loaded for this purpose if it is not already. Otherwise CGI.pm is not | ||||
394 | required or used by this module. | ||||
395 | |||||
396 | Under mod_perl, pass in an Apache request object: | ||||
397 | |||||
398 | $c->bake($r); | ||||
399 | |||||
400 | If you want to set the cookie yourself, Within a CGI script you can send | ||||
401 | a cookie to the browser by creating one or more Set-Cookie: fields in the | ||||
402 | HTTP header. Here is a typical sequence: | ||||
403 | |||||
404 | my $c = CGI::Cookie->new(-name => 'foo', | ||||
405 | -value => ['bar','baz'], | ||||
406 | -expires => '+3M'); | ||||
407 | |||||
408 | print "Set-Cookie: $c\n"; | ||||
409 | print "Content-Type: text/html\n\n"; | ||||
410 | |||||
411 | To send more than one cookie, create several Set-Cookie: fields. | ||||
412 | |||||
413 | If you are using CGI.pm, you send cookies by providing a -cookie | ||||
414 | argument to the header() method: | ||||
415 | |||||
416 | print header(-cookie=>$c); | ||||
417 | |||||
418 | Mod_perl users can set cookies using the request object's header_out() | ||||
419 | method: | ||||
420 | |||||
421 | $r->headers_out->set('Set-Cookie' => $c); | ||||
422 | |||||
423 | Internally, Cookie overloads the "" operator to call its as_string() | ||||
424 | method when incorporated into the HTTP header. as_string() turns the | ||||
425 | Cookie's internal representation into an RFC-compliant text | ||||
426 | representation. You may call as_string() yourself if you prefer: | ||||
427 | |||||
428 | print "Set-Cookie: ",$c->as_string,"\n"; | ||||
429 | |||||
430 | =head2 Recovering Previous Cookies | ||||
431 | |||||
432 | %cookies = CGI::Cookie->fetch; | ||||
433 | |||||
434 | B<fetch> returns an associative array consisting of all cookies | ||||
435 | returned by the browser. The keys of the array are the cookie names. You | ||||
436 | can iterate through the cookies this way: | ||||
437 | |||||
438 | %cookies = CGI::Cookie->fetch; | ||||
439 | for (keys %cookies) { | ||||
440 | do_something($cookies{$_}); | ||||
441 | } | ||||
442 | |||||
443 | In a scalar context, fetch() returns a hash reference, which may be more | ||||
444 | efficient if you are manipulating multiple cookies. | ||||
445 | |||||
446 | CGI.pm uses the URL escaping methods to save and restore reserved characters | ||||
447 | in its cookies. If you are trying to retrieve a cookie set by a foreign server, | ||||
448 | this escaping method may trip you up. Use raw_fetch() instead, which has the | ||||
449 | same semantics as fetch(), but performs no unescaping. | ||||
450 | |||||
451 | You may also retrieve cookies that were stored in some external | ||||
452 | form using the parse() class method: | ||||
453 | |||||
454 | $COOKIES = `cat /usr/tmp/Cookie_stash`; | ||||
455 | %cookies = CGI::Cookie->parse($COOKIES); | ||||
456 | |||||
457 | If you are in a mod_perl environment, you can save some overhead by | ||||
458 | passing the request object to fetch() like this: | ||||
459 | |||||
460 | CGI::Cookie->fetch($r); | ||||
461 | |||||
462 | If the value passed to parse() is undefined, an empty array will returned in list | ||||
463 | context, and an empty hashref will be returned in scalar context. | ||||
464 | |||||
465 | =head2 Manipulating Cookies | ||||
466 | |||||
467 | Cookie objects have a series of accessor methods to get and set cookie | ||||
468 | attributes. Each accessor has a similar syntax. Called without | ||||
469 | arguments, the accessor returns the current value of the attribute. | ||||
470 | Called with an argument, the accessor changes the attribute and | ||||
471 | returns its new value. | ||||
472 | |||||
473 | =over 4 | ||||
474 | |||||
475 | =item B<name()> | ||||
476 | |||||
477 | Get or set the cookie's name. Example: | ||||
478 | |||||
479 | $name = $c->name; | ||||
480 | $new_name = $c->name('fred'); | ||||
481 | |||||
482 | =item B<value()> | ||||
483 | |||||
484 | Get or set the cookie's value. Example: | ||||
485 | |||||
486 | $value = $c->value; | ||||
487 | @new_value = $c->value(['a','b','c','d']); | ||||
488 | |||||
489 | B<value()> is context sensitive. In a list context it will return | ||||
490 | the current value of the cookie as an array. In a scalar context it | ||||
491 | will return the B<first> value of a multivalued cookie. | ||||
492 | |||||
493 | =item B<domain()> | ||||
494 | |||||
495 | Get or set the cookie's domain. | ||||
496 | |||||
497 | =item B<path()> | ||||
498 | |||||
499 | Get or set the cookie's path. | ||||
500 | |||||
501 | =item B<expires()> | ||||
502 | |||||
503 | Get or set the cookie's expiration time. | ||||
504 | |||||
505 | =item B<max_age()> | ||||
506 | |||||
507 | Get or set the cookie's max_age value. | ||||
508 | |||||
