jquery的CORS错误

Question

 $.ajax({
            headers: { "Accept": "application/json"},
            type: 'GET',
            url: 'http://cl.ly/2wr4',
            crossDomain: true,
            success: function(data, textStatus, request){
                console.log(data);
            }
 });

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://cl.ly/2wr4. This can be fixed by moving the resource to the same domain or enabling CORS.

XMLHttpRequest cannot load http://cl.ly/2wr4. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
