RedirectToAction not changing URL or navigating to Index view
提问by kurasa
I tried using a RedirectToActionafter I have done a post to the controller and saved but the URL does not change and the redirect does not seem to work. I need to add that the redirect does enter the controller action method when I debug. It does not change the URL or navigate to the Indexview.
我RedirectToAction在向控制器发送帖子并保存后尝试使用 a ，但 URL 没有更改并且重定向似乎不起作用。我需要补充一点，当我调试时，重定向确实进入了控制器操作方法。它不会更改 URL 或导航到Index视图。
public ViewResult Index()
{
return View("Index", new TrainingViewModel());
}
public ActionResult Edit()
{
// save the details and return to list
return RedirectToAction("Index");
}
What am I doing wrong?
我究竟做错了什么？
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("{resource}.js/{*pathInfo}");
routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
}
jQuery calls:
jQuery 调用：
this.SynchValuesToReadOnly = function() {
window.location = $('#siteRoot').attr('href') + 'Sites/';
};
this.OnSiteEdit = function() {
// post back to the server and update the assessment details
var options = {
target: '',
type: 'post',
url: '/Site/Edit',
beforeSubmit: othis.validate,
success: othis.SynchValuesToReadOnly
};
$('#uxSiteForm').ajaxSubmit(options);
};

The code you show is correct. My wild guess is that you're not doing a standard POST (e.g., redirects don't work with an AJAX post).
您显示的代码是正确的。我的猜测是您没有执行标准的 POST（例如，重定向不适用于 AJAX 帖子）。
The browser will ignore a redirect response to an AJAX POST. It's up to you to redirect in script if you need to redirect when an AJAX call returns a redirect response.
浏览器将忽略对 AJAX POST 的重定向响应。如果您需要在 AJAX 调用返回重定向响应时重定向，则由您在脚本中重定向。

You need to add "return false;" to end of your onclick javascript event. For example:
您需要添加“返回假；” 结束您的 onclick javascript 事件。例如：
Razor Code
剃刀代码
@using (Html.BeginForm())
{
@Html.HiddenFor(model => model.ID)
@Html.ActionLink("Save", "SaveAction", "MainController", null, new { @class = "saveButton", onclick = "return false;" })
}
JQuery Code
查询代码
$(document).ready(function () {
$('.saveButton').click(function () {
$(this).closest('form')[0].submit();
});
});
C#
C＃
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult SaveAction(SaveViewModel model)
{
return RedirectToAction("Index");
}

I just came across this issue and nothing was working for me. It turned out the controller I was redirecting to required Authorization - the [Authorize]attribute was preventing any redirection.
我刚刚遇到了这个问题，但没有什么对我有用。结果是我重定向到所需授权的控制器 - 该[Authorize]属性阻止了任何重定向。
[Authorize]//comment this out
public class HomeController : Controller {...}
Down the road or in larger projects this may not be a desired fix, but if you're only looking for a simple redirection or starting out, this may be a solution for you.
在未来或更大的项目中，这可能不是理想的解决方案，但如果您只是在寻找简单的重定向或开始，这可能是您的解决方案。

Try as below:
尝试如下：
return in your action:
在你的行动中返回：
return Json(Url.Action("Index", "Home"));
return Json(Url.Action("Index", "Home"));
and in your ajax:
在你的 ajax 中：
window.location.href
window.location.href

Check with firebug. Post might be returning a server error.
用萤火虫检查。Post 可能会返回服务器错误。

This is a bit late.... but I had the same problem in MVC5. I had 2 actions with the same name, which is common enough. I wasn't getting any errors that I could capture in Application_Error or OnException in the controller. I tried adding in the action, controller, area in the RedirectToAction route variable to no avail. I ended up renaming the POST action to EditPost and everything works now for me. Hope this helps.
这有点晚了......但我在MVC5中遇到了同样的问题。我有两个同名的动作，这很常见。我没有收到任何可以在控制器中的 Application_Error 或 OnException 中捕获的错误。我尝试在 RedirectToAction 路由变量中添加操作、控制器、区域，但无济于事。我最终将 POST 操作重命名为 EditPost，现在一切都对我有用。希望这可以帮助。
public ActionResult Edit(int id)
{
return View();
}
[HttpPost, ValidateAntiForgeryToken]
public ActionResult Edit(MyInputModel myInputModel)
{
return View();
}
public ActionResult Create()
{
return RedirectToAction("Edit", new {id = 1});
}

I decided to write this comment as a new answer because I think it needs more description and may someone can't see it in comments if has my problem. So I Apologize if you think this is not an answer and must be written in the comment section.
我决定将此评论写为新答案，因为我认为它需要更多描述，如果有我的问题，可能有人无法在评论中看到它。因此，如果您认为这不是答案并且必须写在评论部分，我深表歉意。
In some cases, I used RedirectToAction to send the user to another action if input values are incorrect or insufficient and avoid continuing the current process as below:
在某些情况下，如果输入值不正确或不足，我使用 RedirectToAction 将用户发送到另一个操作，并避免继续当前过程，如下所示：
if (inputValues == null)
{
RedirectToAction("index");
}
That keeps not working and continues the current process to take unhandled error. I search and read some articles but I can't find a solution. Calling of RedirectToAction is not from Ajax code and routing is so simple without any parameters even. So why is not working? Finally, I found the simple mistake I did: Forgot to put "return"keyword before RedirectToAction. I changed the code as below:
这一直不起作用并继续当前过程以处理未处理的错误。我搜索并阅读了一些文章，但找不到解决方案。RedirectToAction 的调用不是来自 Ajax 代码，路由也非常简单，甚至不需要任何参数。那么为什么不工作？最后，我发现了我犯的一个简单错误：忘记在 RedirectToAction 之前放置“return”关键字。我将代码更改如下：
if (inputValues == null)
{
return RedirectToAction("index");
}
And that is worked. Hope this help.
这是有效的。希望这有帮助。

Because I forgot to add app.UseAuthentication() to the code block in the Startup.cs.
因为我忘记在 Startup.cs 的代码块中添加 app.UseAuthentication()。
public void Configure(IApplicationBuilder app, IHostingEnvironment env)

After adding the redirect began to work
