 在PHP文件中设置头信息(支持多域名),例如:

//加入跨域头信息，目前为本机地址和测试地址可通过
$origin = isset($_SERVER['HTTP_ORIGIN'])? $_SERVER['HTTP_ORIGIN'] : '';
$allow_origin = array(

);
if (in_array($origin, $allow_origin)) {
    header("Access-Control-Allow-Origin:" . $origin);
    header('Access-Control-Allow-Headers:Authorization, Content-Type, Depth,User-Agent, X-File-Size, X-Requested-With, X-Requested-By, If-Modified-Since, X-File-Name, X-File-Type, Cache-Control, Origin');
    header('Access-Control-Allow-Methods:GET, POST, PATCH, PUT, OPTIONS');
