  • php发送post请求的三种方法

    引用:http://blog.sjzycxx.cn/post/435/

    1.使用 file_get_contents()

    /**
    * 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,需要2个参数,URL和参数,post的参数得自己构造,是数组的格式
    $post_data = array(
          'username' => 'stclair2201',
          'password' => 'handan'
    );
    send_post('http://www.qianyunlai.com', $post_data);

    2.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;
    }
    ?>

    3.Curl版本

    <?php
    /**
    * Curl版本
    * 使用方法:
    * $post_string = "app=request&version=beta";
    * request_by_curl('http://www.qianyunlai.com/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, "qianyunlai.com's CURL Example beta");
         $data = curl_exec($ch);
         curl_close($ch);

         return $data;
    }
    ?>
