jQuery抛出GET 400错误

Question

I've a jQuery ajax GET request which gives the server a clientId. When the clientId is invalid I return a 400 "Bad token etc...". This works great only I do not understand why jQuery throws this error in the console?

So my question is: "How can I stop jQuery from throwing and simply just call the error callback instead of both"

My code:

        $.ajax({
            type: type,
            url: url,
            timeout: 30000,
            dataType: "text",
            success: function (data, textStatus, jqXHR) {
                callback(textStatus, url, jqXHR, data);
            },
            error: function (jqXHR, textStatus, errorThrown) {
                callback(textStatus, url, jqXHR, errorThrown);
            }
        });

If you are returning a 400 status code it will be considered as a failed request. check this link

About your console showing the error it is the normal behavior. If you don't want it to show an error you shouldn't return an error code: check this link
