如何重定向到 ASP.NET MVC 中的上一个操作? [英] How do I redirect to the previous action in ASP.NET MVC?

问题描述

假设我有一些页面

• some.web/articles/details/5
• some.web/users/info/bob
• some.web/foo/bar/7

可以调用像

这样的通用实用程序控制器

locale/change/es 或 authorization/login

如何让这些方法(change、login)重定向到之前的操作(details、info, bar) 同时将前面的参数传递给它们 (5, bob, 7)?

简而言之:如何在另一个控制器中执行操作后重定向到我刚刚访问的页面?

解决方案

尝试:

public ActionResult MyNextAction(){返回重定向(Request.UrlReferrer.ToString());}

或者，触及达林所说的，试试这个:

public ActionResult MyFirstAction(){return RedirectToAction("MyNextAction",新 { r = Request.Url.ToString() });}

然后:

public ActionResult MyNextAction(){返回重定向(Request.QueryString["r"]);}

Lets suppose that I have some pages

• some.web/articles/details/5
• some.web/users/info/bob
• some.web/foo/bar/7

that can call a common utility controller like

locale/change/es or authorization/login

How do I get these methods (change, login) to redirect to the previous actions (details, info, bar) while passing the previous parameters to them (5, bob, 7)?

In short: How do I redirect to the page that I just visited after performing an action in another controller?

解决方案

try:

public ActionResult MyNextAction()
{
    return Redirect(Request.UrlReferrer.ToString());
}

alternatively, touching on what darin said, try this:

public ActionResult MyFirstAction()
{
    return RedirectToAction("MyNextAction",
        new { r = Request.Url.ToString() });
}

then:

public ActionResult MyNextAction()
{
    return Redirect(Request.QueryString["r"]);
}
