[英]MVC View rendering as raw HTML
I use this code in my Global.asax file to catch all 404 errors and redirect them to a custom controller/view. 我在我的Global.asax文件中使用此代码来捕获所有404错误并将它们重定向到自定义控制器/视图。
protected void Application_Error(object sender, EventArgs e) {
Exception exception = Server.GetLastError();
Response.Clear();
HttpException httpException = exception as HttpException;
if (httpException != null) {
if (httpException.GetHttpCode() == 404) {
RouteData routeData = new RouteData();
routeData.Values.Add("controller", "Error");
routeData.Values.Add("action", "Index");
Server.ClearError();
IController errorController = new webbage.chat.Controllers.ErrorController();
Response.StatusCode = 404;
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
}
}
}
I have three controllers for my application at the moment, Users
, Rooms
and Home
我目前有三个控制器用于我的应用程序,
Users
, Rooms
和Home
When I type in something like {localhost}/rooms/999
(this would cause it to throw a 404 since 999 is an invalid room Id), it redirects and renders just fine, everything works as expected. 当我输入像
{localhost}/rooms/999
这样的东西时(这会导致它抛出404,因为999是一个无效的房间ID),它会重定向并渲染得很好,一切都按预期工作。
However if I type in an invalid controller name like so {localhost}/test
it redirects it to the view like it should, but when it renders it's just the HTML as plain text. 但是,如果我键入一个像
{localhost}/test
这样的无效控制器名称,它会将它重定向到视图,但是当它呈现它时,它只是HTML作为纯文本。 Can someone point out why it would do that? 有人能指出为什么会这样做吗?
Here's my ErrorController 这是我的ErrorController
public class ErrorController : Controller {
public ActionResult Index() {
return View();
}
public ActionResult NotFound() {
return View();
}
public ActionResult Forbidden() {
return View();
}
}
And my view: 我的观点是:
@{
ViewBag.Title = "Error";
}
<div class="container">
<h1 class="text-pumpkin">Ruh-roh</h1>
<h3 class="text-wet-asphalt">The page you're looking for isn't here.</h3>
</div>
I ended up going with just web.config error handling since it's much simpler I suppose. 我最后只使用web.config错误处理,因为我认为它更简单。 I removed the Application_Error code from my Global.asax file and just put this snippet in my web.confg file
我从Global.asax文件中删除了Application_Error代码,并将此代码段放在我的web.confg文件中
<system.webServer>
<httpErrors errorMode="Custom" existingResponse="Replace">
<remove statusCode="403"/>
<remove statusCode="404"/>
<remove statusCode="500"/>
<error statusCode="403" responseMode="ExecuteURL" path="/Error/Forbidden" />
<error statusCode="404" responseMode="ExecuteURL" path="/Error/NotFound" />
<error statusCode="500" responseMode="ExecuteURL" path="/Error" />
</httpErrors>
</system.webServer>
I'd still love to know why this is occurring though. 我仍然很想知道为什么会这样。
You can try explicitly setting the ContentType in the action: 您可以尝试在操作中显式设置ContentType:
public ActionResult NotFound() {
// HACK: fix rendering raw HTML when a controller can't be found
Response.ContentType = "text/html";
return View();
}
