跨域（php）

        //解決跨域問題
/*      header('Access-Control-Allow-Origin:*');//允許所有來源訪問
        header('Access-Control-Allow-Method:POST,GET');//允許訪問的方式*/

        if($_SERVER['REQUEST_METHOD'] == 'OPTIONS'){
            header("Access-Control-Allow-Origin: *");
            header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");
            header('Access-Control-Allow-Methods: GET, POST, PUT,DELETE,OPTIONS,PATCH');
           exit;
        }
        header("Access-Control-Allow-Origin: *");
        header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");
        header('Access-Control-Allow-Methods: GET, POST, PUT,DELETE,OPTIONS,PATCH');

或

// 指定允許其他域名訪問
header('Access-Control-Allow-Origin:*');
// 響應類型
header('Access-Control-Allow-Methods:*');
// 響應頭設置
header('Access-Control-Allow-Headers:x-requested-with,content-type');

 

把上面的代碼放在所有方法最前面即可
