方法一:file_get_content版本
/** * 发送post请求 * @param string $url 请求地址 * @param array $post_data post键值对数据 * @return string */ function send_post($url, $post_data) { $postdata = http_build_query($post_data); $options = array( 'http' => array( 'method' => 'POST', 'header' => 'Content-type:application/x-www-form-urlencoded', 'content' => $postdata, 'timeout' => 15 * 60 // 超时时间(单位:s) ) ); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); return $result; } //使用方法 $post_data = array( 'username' => 'stclair2201', 'password' => 'handan' ); send_post('http://www.jb51.net', $post_data);

方法二:Socket版本
<?php /** * Socket版本 * 使用方法: * $post_string = "app=socket&version=beta"; * request_by_socket('chajia8.com', '/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 $remote_path HTTP/1.0"); fwrite($socket, "User-Agent: Socket Example"); fwrite($socket, "HOST: $remote_server"); fwrite($socket, "Content-type: application/x-www-form-urlencoded"); fwrite($socket, "Content-length: " . (strlen($post_string) + 8) . ""); fwrite($socket, "Accept:*/*"); fwrite($socket, ""); fwrite($socket, "mypost=$post_string"); fwrite($socket, ""); $header = ""; while ($str = trim(fgets($socket, 4096))) { $header .= $str; } $data = ""; while (!feof($socket)) { $data .= fgets($socket, 4096); } return $data; } ?>
方法三:Curl版本
<?php /** * Curl版本 * 使用方法: * $post_string = "app=request&version=beta"; * request_by_curl('http://www.jb51.net/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, "jb51.net's CURL Example beta"); $data = curl_exec($ch); curl_close($ch); return $data; } ?>
