php实现模拟post请求用法实例

本文实例讲述了php实现模拟post请求的方法。分享给大家供大家参考。具体如下：

    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=array()){//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;
     }
    }
    $url='http://******/con/Inter.php';
    $data=Request::post($url,array('api'=>'tag_list'));
    $data2=Request::post2($url,array('api'=>'tag_list'));
    echo $data;
