php 跨域问题

设置header

<?php
$origin = isset($_SERVER['HTTP_ORIGIN'])? $_SERVER['HTTP_ORIGIN']:'';$allow_origin=array('http://www.aaa.com','http://www.bbb.com',
);
if( $origin in $allow_origin ){header("Access-Control-Allow-Origin:".$origin);header("Access-Control-Allow-Headers:Content-Type,Authorization,X-CSRFToken, Token");header("Access-Control-Allow-Methods:GET,POST");}

注：不要用param()获取参数，要不然配置了hearder也不会生效！！！
