php寫的http請求封裝類

本文介紹一個php實現的http請求封裝類，封裝了三種post提交方法和一個request要求方法，並提供了調用樣本，供大家學習參考。 在php編程調試時，經常需要類比提交。另外，在抓取一些頁面時，需要經常請求別人的頁面。 於是實現了一個http請求的封裝類，以方便調用。本http請求類，封裝了三種post提交方法和一個request要求方法。 1，http請求封閉類 0) { $this->init($params); } } // ----------------------- /** * 參數初始化 * * @param array $params */ public function init($params) { if(count($params) > 0) { foreach($params as $key => $val) { if(isset($this->$key)) { $this->$key = $val; } } } } // ----------------------- /** * 提交請求 * * @param string $url 請求地址 * @param mixed $data 提交的資料 * @param string $type 提交類型，curl,socket,stream可選 */ public function post($url, $data, $type = "socket") { if(!in_array($type, $this->post_type_list)) { die("undefined post type"); } $function_name = $type .
