From fa37967858c3c29000797e510e5f98aca8ab558f Mon Sep 17 00:00:00 2001 From: Brion Vibber Date: Wed, 28 Oct 2009 15:29:20 -0400 Subject: [PATCH] Rebuilt HTTPClient class as an extension of PEAR HTTP_Request2 package, adding redirect handling and convenience functions. Caching support will be added in future work after unit tests have been added. * extlib: add PEAR HTTP_Request2 0.4.1 alpha * extlib: update PEAR Net_URL2 to 0.3.0 beta for HTTP_Request2 compatibility * moved direct usage of CURL and file_get_contents to HTTPClient class, excluding external-sourced libraries Note some plugins haven't been tested yet. --- classes/File_redirection.php | 66 +- extlib/HTTP/Request2.php | 844 +++++++++++++++ extlib/HTTP/Request2/Adapter.php | 152 +++ extlib/HTTP/Request2/Adapter/Curl.php | 383 +++++++ extlib/HTTP/Request2/Adapter/Mock.php | 171 +++ extlib/HTTP/Request2/Adapter/Socket.php | 971 ++++++++++++++++++ extlib/HTTP/Request2/Exception.php | 62 ++ extlib/HTTP/Request2/MultipartBody.php | 274 +++++ extlib/HTTP/Request2/Observer/Log.php | 215 ++++ extlib/HTTP/Request2/Response.php | 549 ++++++++++ extlib/Net/URL2.php | 471 +++++---- install.php | 7 + lib/Shorturl_api.php | 23 +- lib/curlclient.php | 179 ---- lib/default.php | 2 - lib/httpclient.php | 196 +++- lib/oauthclient.php | 63 +- lib/ping.php | 14 +- lib/snapshot.php | 21 +- plugins/BlogspamNetPlugin.php | 17 +- plugins/LinkbackPlugin.php | 36 +- plugins/SimpleUrl/SimpleUrlPlugin.php | 11 +- .../daemons/synctwitterfriends.php | 4 +- .../daemons/twitterstatusfetcher.php | 45 +- plugins/TwitterBridge/twitter.php | 2 +- .../TwitterBridge/twitterauthorization.php | 2 +- .../TwitterBridge/twitterbasicauthclient.php | 64 +- plugins/WikiHashtagsPlugin.php | 12 +- scripts/enjitqueuehandler.php | 62 +- 29 files changed, 4245 insertions(+), 673 deletions(-) create mode 100644 extlib/HTTP/Request2.php create mode 100644 extlib/HTTP/Request2/Adapter.php create mode 100644 extlib/HTTP/Request2/Adapter/Curl.php create mode 100644 extlib/HTTP/Request2/Adapter/Mock.php create mode 100644 extlib/HTTP/Request2/Adapter/Socket.php create mode 100644 extlib/HTTP/Request2/Exception.php create mode 100644 extlib/HTTP/Request2/MultipartBody.php create mode 100644 extlib/HTTP/Request2/Observer/Log.php create mode 100644 extlib/HTTP/Request2/Response.php delete mode 100644 lib/curlclient.php diff --git a/classes/File_redirection.php b/classes/File_redirection.php index 79052bf7d3..b7945699ab 100644 --- a/classes/File_redirection.php +++ b/classes/File_redirection.php @@ -47,18 +47,15 @@ class File_redirection extends Memcached_DataObject /* the code above is auto generated do not remove the tag below */ ###END_AUTOCODE - function _commonCurl($url, $redirs) { - $curlh = curl_init(); - curl_setopt($curlh, CURLOPT_URL, $url); - curl_setopt($curlh, CURLOPT_AUTOREFERER, true); // # setup referer header when folowing redirects - curl_setopt($curlh, CURLOPT_CONNECTTIMEOUT, 10); // # seconds to wait - curl_setopt($curlh, CURLOPT_MAXREDIRS, $redirs); // # max number of http redirections to follow - curl_setopt($curlh, CURLOPT_USERAGENT, USER_AGENT); - curl_setopt($curlh, CURLOPT_FOLLOWLOCATION, true); // Follow redirects - curl_setopt($curlh, CURLOPT_RETURNTRANSFER, true); - curl_setopt($curlh, CURLOPT_FILETIME, true); - curl_setopt($curlh, CURLOPT_HEADER, true); // Include header in output - return $curlh; + static function _commonHttp($url, $redirs) { + $request = new HTTPClient($url); + $request->setConfig(array( + 'connect_timeout' => 10, // # seconds to wait + 'max_redirs' => $redirs, // # max number of http redirections to follow + 'follow_redirects' => true, // Follow redirects + 'store_body' => false, // We won't need body content here. + )); + return $request; } function _redirectWhere_imp($short_url, $redirs = 10, $protected = false) { @@ -82,32 +79,39 @@ class File_redirection extends Memcached_DataObject if(strpos($short_url,'://') === false){ return $short_url; } - $curlh = File_redirection::_commonCurl($short_url, $redirs); - // Don't include body in output - curl_setopt($curlh, CURLOPT_NOBODY, true); - curl_exec($curlh); - $info = curl_getinfo($curlh); - curl_close($curlh); + try { + $request = self::_commonHttp($short_url, $redirs); + // Don't include body in output + $request->setMethod(HTTP_Request2::METHOD_HEAD); + $response = $request->send(); - if (405 == $info['http_code']) { - $curlh = File_redirection::_commonCurl($short_url, $redirs); - curl_exec($curlh); - $info = curl_getinfo($curlh); - curl_close($curlh); + if (405 == $response->getCode()) { + // Server doesn't support HEAD method?
