ASP.NET MVC 4 - 在控制器结束后重定向到同一页面

From a page I have the following:

从页面我有以下内容：

@using (Html.BeginForm("AddEntry", "Configure", FormMethod.Get, new { returnUrl = this.Request.RawUrl }))
{
    @Html.TextBox("IP")
    @Html.Hidden("TypeId", 1)
    <input type="submit" value="@Resource.ButtonTitleAddComponent" />
}

so controller is called correctly:

所以控制器被正确调用：

public ActionResult AddEntry(string ip, int TypeId, string returnUrl)
{
    // Do some stuff

    return Redirect(returnUrl);
}

My problem is that returnUrl gets null and it does not redirect to the same page that called the controller. Ideas?

我的问题是returnUrl获取null并且它不会重定向到调用控制器的同一页面。想法？

#1

You could use a Request.QueryString method to get some values from URL, for sample:

您可以使用Request.QueryString方法从URL获取一些值，用于示例：

@using (Html.BeginForm("AddEntry", "Configure", FormMethod.Get, null))
{
    @Html.TextBox("ip")
    @Html.Hidden("TypeId", 1)
    @Html.Hidden("returnUrl", this.Request.RawUrl)
    <input type="submit" value="@Resource.ButtonTitleAddComponent" />
}

And in your controller, receive it as a parameter string returnUrl.

在您的控制器中，将其作为参数字符串returnUrl接收。

you can also do this if you need to return to something like details page and return to the same page with a query:

如果您需要返回类似详细信息页面并返回同一页面查询，您也可以这样做：

return Redirect(Request.UrlReferrer.PathAndQuery);

#3

You can get the Refer URL from the Request in the controller:

您可以从控制器中的Request获取Refer URL：

public ActionResult AddEntry(string ip, int TypeId, string returnUrl)
{

     // Do some stuff
     string url = this.Request.UrlReferrer.AbsolutePath;

     return Redirect(url);
}

This will redirect you exactly to the calling URL.

这会将您重定向到调用URL。

#4

in your controller class use Request.UrlReferrer. There's no need to pass the url from the page.

在您的控制器类中使用Request.UrlReferrer。没有必要从页面传递URL。

   public ActionResult AddEntry(string ip, int TypeId)
    {

         // Do some stuff

         return Redirect(Request.UrlReferrer.ToString());
    }

#5

@using (Html.BeginForm("AddEntry", "Configure", new { returnUrl = this.Request.RawUrl }))
{
    @Html.TextBox("IP")
    @Html.Hidden("TypeId", 1)
    <input type="submit" value="@Resource.ButtonTitleAddComponent" />
}

on Get like Edit(int? id)

在Get上编辑（int？id）
```
ViewBag.RefUrl = Request.UrlReferrer.ToString();
```
on view @Html.Hidden("RefUrl");
on view @ Html.Hidden（“RefUrl”）;
on post Edit(int id,string RefUrl)

在帖子编辑（int id，string RefUrl）
```
return Redirect(RefUrl);
```
