    欄目:win服務器問題匯總 時間:2019-11-25 21:41

    方法一:

    /**
     * 發送post請求
     * @param string $url 請求地址
     * @param array $post_data post鍵值對數據
     * @return string
     */
    function send_post($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 // 超時時間(單位: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('//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('//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;
    }
    ?>

    下面是其他網友的方法:

    class Request{
      public static function post($url, $post_data = '', $timeout = 5){//curl
        $ch = curl_init();
        curl_setopt ($ch, CURLOPT_URL, $url);
        curl_setopt ($ch, CURLOPT_POST, 1);
        if($post_data != ''){
          curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        }
        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
        curl_setopt($ch, CURLOPT_HEADER, false);
        $file_contents = curl_exec($ch);
        curl_close($ch);
        return $file_contents;
      }
      public static function post2($url, $data){//file_get_content
        
        $postdata = http_build_query(
          $data
        );
        
        $opts = array('http' =>
               array(
                 'method' => 'POST',
                 'header' => 'Content-type: application/x-www-form-urlencoded',
                 'content' => $postdata
               )
        );
        
        $context = stream_context_create($opts);
        $result = file_get_contents($url, false, $context);
        return $result;
      }
      public static function post3($host,$path,$query,$others=''){//fsocket
        $post="POST $path HTTP/1.1\r\nHost: $host\r\n";
        $post.="Content-type: application/x-www-form-";
        $post.="urlencoded\r\n${others}";
        $post.="User-Agent: Mozilla 4.0\r\nContent-length: ";
        $post.=strlen($query)."\r\nConnection: close\r\n\r\n$query";
        $h=fsockopen($host,80);
        fwrite($h,$post);
        for($a=0,$r='';!$a;){
            $b=fread($h,8192);
            $r.=$b;
            $a=(($b=='')?1:0);
          }
        fclose($h);
        return $r;
      }
    }
