thinkphp 允许跨域配置

header("Access-Control-Allow-Origin:*");
header("Access-Control-Allow-Methods:GET, POST, OPTIONS, DELETE");
header("Access-Control-Allow-Headers:DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type, Accept-Language, Origin, Accept-Encoding, Authorization");

在入口文件加入这个就可以跨域请求了

路径：\public\index.php
