Failed to load http://localhost:8080/XXXX: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8081' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
说明接口输入格式跨域没有设置，在 thinkphp中接口输出或index.php中添加代码 ：
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');
