jQuery AJAX 请求总是失败

jQuery AJAX request always fails

当我做这个AJAX调用时

var BASE_URL =  "http://127.0.0.1:8000/index.php";
$.get(BASE_URL + "?r=category")
            .done(function (data) {
                alert('success');
            })
            .fail(function (error) {
                alert('error');
            });

这是服务器响应（使用 Fiddler 检查）

HTTP/1.1 200 OK

[{"CaID":1,"Name":"Brot und Gebäck","ParentCaID":null},{"CaID":2,"Name":"Süßes und Salziges","ParentCaID":null},{"CaID":3,"Name":"Getränke","ParentCaID":null}]

但它总是调用 fail 函数。

var BASE_URL =  "http://127.0.0.1:8000/index.php";
$.get(BASE_URL + "?r=category")
        .done(function (data) {
            alert('success');
        })
        .fail(function (error) {
            console.log(error);//to show what error happended
            alert('error');
        });
