在php中有很多种方法可以实现模拟提交的，下面我整理了四种post提交数据的例子，希望对各位同学会带来帮助。

//以程序登陆一个论坛登录为例 function bbslogin($user_login, $password, $host, $port = "80") { //需要提交的post数据 $argv = array('cookie' => array('user_login' => $user_login, 'password' => $password, '_wp_http_referer' => '/bbpress/', 're' => '', 'remember' => true)); foreach ($argv['cookie'] as $key => $value) { $params[] = $key . '=' . $value; } $params = implode('&', $params); $header = "POST /bbpress/bb-login.php HTTP/1.1rn"; $header .= "Host:$host:$portrn"; $header .= "Content-Type: application/x-www-form-urlencodedrn"; $header .= "Content-Length: " . strlen($params) . "rn"; $header .= "Connection: Closernrn"; $header .= $params; $fp = fsockopen($host, $port); fputs($fp, $header); while (!feof($fp)) { $str = fgets($fp); //以下是自己的逻辑代码,这里主要是模拟cookie,可用来同步登陆 if (!(strpos($str, "Set-Cookie:") === false)) { $tmparray = explode(" ", $str); $cookiearray = explode("=", $tmparray[1]); $cookiepaths = explode("=", $tmparray[6]); $cookiename = urldecode($cookiearray[0]); $cookievalue = urldecode(substr($cookiearray[1], 0, strlen($cookiearray[1]) - 1)); $cookietime = time() + 3600 * 24 * 7; $cookiepath = urldecode(substr($cookiepaths[1], 0, strlen($cookiepaths[1]) - 1)); setcookie($cookiename, $cookievalue, $cookietime, $cookiepath); } } fclose($fp); } ?> // PHP POST数据的三种方法 // php有三种方法可以post数据,分别为Curl、socket、file_get_contents: /** * Socket版本 * 使用方法： * $post_string = "app=socket&version=beta"; * request_by_socket('facebook.cn','/restServer.php',$post_string); */ function request_by_socket($remote_server, $remote_path, $post_string, $port = 80, $timeout = 30) { $socket = fsockopen($remote_server, $port, $errno, $errstr, $timeout); if (!$socket) die("$errstr($errno)"); fwrite($socket, "POST $remote_path HTTP/1.0rn"); fwrite($socket, "User-Agent: Socket Examplern"); fwrite($socket, "HOST: $remote_serverrn"); fwrite($socket, "Content-type: application/x-www-form-urlencodedrn"); fwrite($socket, "Content-length: " . (strlen($post_string) + 8) . 'rn'); fwrite($socket, "Accept:*/*rn"); fwrite($socket, "rn"); fwrite($socket, "mypost=$post_stringrn"); fwrite($socket, "rn"); $header = ""; while ($str = trim(fgets($socket, 4096))) { $header .= $str; } $data = ""; while (!feof($socket)) { $data .= fgets($socket, 4096); } return $data; } /** * Curl版本 * 使用方法： * $post_string = "app=request&version=beta"; * request_by_curl('http://facebook.cn/restServer.php',$post_string); */ function request_by_curl($remote_server, $post_string) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $remote_server); curl_setopt($ch, CURLOPT_POSTFIELDS, 'mypost=' . $post_string); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERAGENT, "Jimmy's CURL Example beta"); $data = curl_exec($ch); curl_close($ch); return $data; } /** * 其它版本 * 使用方法： * $post_string = "app=request&version=beta"; * request_by_other('http://facebook.cn/restServer.php',$post_string); */ function request_by_other($remote_server, $post_string) { $context = array( 'http' => array( 'method' => 'POST', 'header' => 'Content-type: application/x-www-form-urlencoded' . 'rn'.'User-Agent : Jimmy's POST Example beta' . 'rn'.'Content-length:' . strlen($post_string) + 8, 'content' => 'mypost=' . $post_string) ); $stream_context = stream_context_create($context); $data = file_get_contents($remote_server, false, $stream_context); return $data; } ?> |
