ThinkPHP 設置跨域請求

場景：我的本地網頁服務器無法訪問本地的接口服務器接口提示一下錯誤：大致意思是：是一個跨域請求我的沒有訪問該地址的權限（接口服務器采用的是PHP編寫）

XMLHttpRequest cannot load http://localhost/mz/goods/getList. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8020' is therefore not allowed access.

解決方案：

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
header('Access-Control-Allow-Methods: GET, POST, PUT');

為ajaxReturn 方法設置允許跨域訪問的請求頭。
