查询字符串和渲染操作

发布于 2024-12-25 13:22:10 字数 654 浏览 7 评论 0原文

当发送特定的查询字符串参数时，我在 html 标签上设置一个类，现在我正在这样做（Razor 视图母版页）：

@if (HttpContext.Current.Request.QueryString.AllKeys.Contains("Foo") && HttpContext.Current.Request.QueryString["Foo"] == "Bar") {
  //Do something when Foo=Bar (like http://server/route?Foo==Bar)
  <html class="bar-class">
}
else {
  //Normal html tag
  <html>
}

对于正常请求工作正常，但当我使用 RenderAction 调用页面时则不行，就像

//Other view, the one requested by the user
@Html.RenderAction("Index", "Route", new {Foo="Bar"})

环顾四周后我意识到只有一个实际的 HttpContext，这意味着 HttpContext.Current 指向第一个请求。那么 - 如何获取子请求的查询字符串数据？

谢谢！ /胜利者

I'm setting a class on my html tag when a specific query string argument is sent, right now I'm doing it like this (Razor view master page):

@if (HttpContext.Current.Request.QueryString.AllKeys.Contains("Foo") && HttpContext.Current.Request.QueryString["Foo"] == "Bar") {
  //Do something when Foo=Bar (like http://server/route?Foo==Bar)
  <html class="bar-class">
}
else {
  //Normal html tag
  <html>
}

Works fine for normal requests, but not when I call the page using RenderAction, like

//Other view, the one requested by the user
@Html.RenderAction("Index", "Route", new {Foo="Bar"})

After some looking around I have realized that there only is one actual HttpContext, which means that HttpContext.Current points to the first request. So - how do I get the query string data for the sub request?

Thanks!

您可以使用字符串作为您的模型，而不是针对查询字符串进行操作。

@model string
@if (!string.IsNullOrWhiteSpace(Model) && Model == "Bar") {
  //Do something when Foo=Bar (like http://server/route?Foo==Bar)
  <html class="bar-class">
}
else {
  //Normal html tag
  <html>
}

public ActionResult Route(string foo){
  return View(foo);
}

Instead of working against the query string you could use a string as your Model.

@model string
@if (!string.IsNullOrWhiteSpace(Model) && Model == "Bar") {
  //Do something when Foo=Bar (like http://server/route?Foo==Bar)
  <html class="bar-class">
}
else {
  //Normal html tag
  <html>
}

public ActionResult Route(string foo){
  return View(foo);
}
