ajax获取请求导致错误，但是提琴手给出了200响应

Question

we are trying to do a cross-domain GET request using TypeScript. We tested alleady with a XMLHttpRequest, a $.get and $.ajax.

Using XMLHttpRequest, the onreadystatechange never get triggered. When using the $.ajax way, we noticed we received an error (text was 'error' :( ). The strange part is, fiddler returns a 200 response, and looking in a the textview, we can see all the text we requested.

The response the server is sending is HTML / Text. This is the code we tried:

public GetFeatureInfo(url: string): void {

            $.ajax({
                url: url,
                type: 'GET',
                cache: false,
                dataType: 'text',
                beforeSend: function (xhr) {
                    xhr.overrideMimeType("text/plain; charset=UTF-8");
                }
            }).done(function (data) {
                alert(data);
            }).fail(function (jqXHR, textStatus) {

                alert("Request failed: " + textStatus);
            }).always(function () {

            });
        }

Any ideas?

Thank you for your help!
