RedirectToRoute（QUOT;默认＆QUOT;）和重定向（RETURNURL）正在返回'200'而不是'302' [英] RedirectToRoute("Default") and Redirect(returnUrl) are returning '200' instead of '302'

问题描述

我尝试使用下面的code到登录的用户：

I'm trying to use the following code to log users in:

$("form").submit(function(event)
{
    $.ajax({
        type: "POST",
        url: $(this).attr("action"),
        data: $(this).serialize(),
        complete: function(XMLHttpRequest, textStatus)
        {
            if (XMLHttpRequest.status === 302)
            {
                // if they've successfully logged in, I redirect to their page
                window.location = XMLHttpRequest.getResponseHeader("Location");
            }
        }
    });

    return false;
});

在服务器上的以下code处理后：

with the following code on the server to handle the post:

[AcceptVerbs(HttpVerbs.Post)]
public  ActionResult LogOn(MyUser user)
{
    if (ValidateLogOn(user.UserName, user.Password))
    {
        if (Request.QueryString["ReturnUrl"] != null)
        {
            return Redirect(Request.QueryString["ReturnUrl"]);
        }
        else
        {
            return RedirectToRoute("Default");
        }
    }
}

我想这两个重定向操作的结果被认为发行302S但XMLHtt prequest.status值始终为200。有什么我做错了吗？

I thought both 'Redirect' Action Results were supposed to issue 302s but the XMLHttpRequest.status value is always 200. Is there something I'm doing wrong?

编辑：这是什么最终制定

$("form").submit(function(event)
{
    $.ajax({
        type: "POST",
        url: $(this).attr("action"),
        data: $(this).serialize(),
        complete: function(xhr, textStatus)
        {
            var dataType = xhr.getResponseHeader("Content-Type");

            if (dataType.indexOf("json") > -1)
            {
                window.location = JSON.parse(xhr.responseText).returnUrl;
            }

            if (dataType.indexOf("html") > -1)
            {
                $('#main').html(xhr.responseText);
            }
        }
    });            
    return false;
});    

在服务器上的以下内容：

with the following on the server:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult LogOn(MyUser user, string returnUrl)
{
    if (!ValidateLogOn(user.UserName, user.Password))
    {
        return PartialView();
    }
    else
    {
        user = (MyUser)Session["CurrentUser"];
        if (user.IsPublic)
        {
            return Json(new { returnUrl = Url.RouteUrl("PublicRoute") });
        }
        else
        {
            if (!string.IsNullOrEmpty(returnUrl))
            {
                return Json(new { returnUrl = returnUrl.ToLower() });
            }
            else
            {
                return Json(new { returnUrl = Url.RouteUrl("AdminRoute") });
            }
        }
    }
}

推荐答案

您的浏览器将自动跟随重定向并请求重定向页面，然后返回 200 。运行一个代理（如小提琴手或查尔斯）要明白我的意思。

Your browser is automatically following the redirect and requesting the redirect page, which is then returning 200. Run a proxy (like Fiddler or Charles) to see what I mean.

我建议返回 200 状态，但使用JSON对象来指定要重定向用户。

I'd recommend returning a 200 status, but use a JSON object to specify that you want to redirect the user.

此外，<一个href=\"http://stackoverflow.com/questions/199099/how-to-manage-a-redirect-request-after-a-jquery-ajax-call/1534662#1534662\">this回答建议在这种情况下使用状态 278 （显然未使用状态code，这听起来危险对我来说）。

Additionally, this answer recommends using status 278 (apparently an unused status code, which sounds dangerous to me) in this scenario.
