使用HttpResponseMessage 401在Ajax帖子上始终成功 [英] Always success on ajax post with HttpResponseMessage 401

问题描述

我总是在客户端的ajax帖子上得到statusCode=200，而服务器用HttpStatusCode.Unauthorized回答.

I always get statusCode=200 on ajax post at client side, while servers answers with HttpStatusCode.Unauthorized.

我的控制器代码:

public class AccountApiController : ApiController
{
    public HttpResponseMessage Login(HttpRequestMessage request, [FromBody]LoginViewModel loginModel)
    {
        return request.CreateErrorResponse(HttpStatusCode.Unauthorized, "Unauthorized login.");
    }
}

我的Ajax代码:

$.ajax({
    url: '/api/accountapi/login',
    type: 'POST',
    data: data
    })
    .done(function (object, status, xhr) {
        alert("Success: " + xhr.status + " : " + xhr.statusText);
    })
    .always(function (object) {
        $("#output").text(JSON.stringify(object, null, 4));
    });

结果:带有文本Success: 200 : OK的警报 和带有以下内容的输出窗口:

Result: alert with text Success: 200 : OK and output window with:

{
    "Message": "Unauthorized login."
}

因此，我可以获得文本错误消息，但是我需要获取HttpStatusCode来处理错误语句.请帮帮我.

So, I can get text error message, but i need to get HttpStatusCode to handle error statements. Help me, please.

推荐答案

可能是您返回HttpStatusCode.Unauthorized后，表单认证模块将您的页面重定向到登录页面.

It might be that your page is redirecting to a login page by the forms authentication module as soon as you return HttpStatusCode.Unauthorized.

从MSDN:

所有未经身份验证的用户都被拒绝访问您的任何页面 应用.如果未经身份验证的用户尝试访问页面，则 表单身份验证模块将用户重定向到登录页面 由forms元素的loginUrl属性指定.

All unauthenticated users are denied access to any page in your application. If an unauthenticated user tries to access a page, the forms authentication module redirects the user to the logon page specified by the loginUrl attribute of the forms element.

然后以状态代码200进入登录页面或将其重定向到的任何页面.

The login page, or whatever page it's being redirected to, is then served with status code 200.
