ASP.NET MVC中的操作方法取出查询字符串 [英] ASP.NET MVC Remove query string in action method

问题描述

我的操作方法是这样的：

I have an action method that looks like this:

public ActionResult Index(string message)
{
  if (message != null)
  {
    ViewBag.Message = message;
  }
  return View();
}

什么情况是，这一请求的URL看起来像：

What happens is that the url of a request to this will look like:

www.mysite.com/controller/?message=Hello%20world

但我希望它只是看看

But I want it to look just

www.mysite.com/controller/

有没有办法去除actionmethod内的查询字符串？

Is there a way to remove the query string inside the actionmethod?

推荐答案

没有，除非你使用POST方法，信息要得到某种方式传递。另一种可能是使用一个中间级。

No, unless you use a POST method, the information has to get passed somehow. An alternative may be to use an in-between class.

// this would work if you went to controller/SetMessage?message=hello%20world

public ActionResult SetMessage(string message)
{
  ViewBag.Message = message ?? "";
  return RedirectToAction("Index");
}

public ActionResult Index()
{
  ViewBag.Message = TempData["message"] != null ? TempData["message"] : "";
  return View();
}

或者。如果你只是使用POST

Or. if you simply used a POST

//your view:
@using(Html.BeginForm())
{
    @Html.TextBox("message")
    <input type="submit" value="submit" />
}


[HttpGet]
public ActionResult Index()
{ return View(); }

[HttpPost]
public ActionResult Index(FormCollection form)
{
  ViewBag.Message = form["message"];
  return View();
}
