php發送post請求函數分享

 這篇文章主要介紹了一個php發送post請求的函數,開發中經常會用到,需要的朋友可以參考下

 代碼如下: function do_post_request($url, $data, $optional_headers = null) {  $params = array('http' => array( 'method' => 'POST', 'content' => $data  ));  if ($optional_headers !== null) { $params['http']['header'] = $optional_headers;  }  $ctx = stream_context_create($params);  $fp = @fopen($url, 'rb', false, $ctx);  if (!$fp) { throw new Exception("Problem with $url, $php_errormsg");  }  $response = @stream_get_contents($fp);  if ($response === false) { throw new Exception("Problem reading data from $url, $php_errormsg");  }  return $response; }       用法如下:  代碼如下: //json字符串 $data = "{...}"; //轉換成數組 $data=json_decode($data,true); $postdata = http_build_query($data); do_post_request("http://localhost",$postdata);
