c# – 具有特殊字符和子操作的MVC路由参数

2023-07-26 08:28:16

我有以下路线,它需要能够处理其中任何角色的游戏.我在web.config中正确启用了一些东西以允许URL中的特殊字符,并确认我的URL在使用基本查询字符串而不是自定义MVC路由时有效.但是,只要我通过Html.Action包含子操作加载,我就会得到以下堆栈跟踪.

routes.MapRoute("Game", "Game/Game/{id}", new { controller = "Game", action = "Game", id = ""}, new { id = @"[^\.]*" });

这是我的Controller方法和视图(我把它们弄了很多,但错误仍然存在),它被路由调用,甚至视图内部的剃刀也会被调用,但后来我得到了下面的错误/堆栈跟踪.

控制器：

public ActionResult Game(string id)
  {
     {
        Game currentGame = _ugdb.Games.FirstOrDefault(g => g.GameName.Equals(id));
        return View(currentGame);

  }

视图：

@model UltimateGameDB.Domain.Entities.Game
@Html.Action("SearchBar", "Search")
<span>@Model.GameName</span>

子动作控制器方法(不被调用)：

[ChildActionOnly]
  public ActionResult SearchBar()
  {
     ViewBag.TotalGames = _ugdb.Game_Platform.Count() + _ugdb.Games.Count(g => g.Game_Platform.Count == 0);
     return PartialView("_SearchBar");
  }

以下是一些不起作用的路线示例：

http://localhost:58386/Game/Game/Sid%20Meier%27s%20Civilization%3a%20Beyond%20Earth

http://localhost:58386/Game/Game/Starcraft%20II%3a%20Heart%20of%20the%20Swarm

虽然我的数据库中基本上任何具有特殊字符的游戏都会出现同样的错误.实际的错误消息如下：

我用google搜索了一堆,似乎无法弄清楚为什么这条路线不起作用.

提前致谢！

解决方法:

尝试在httpRuntime元素中设置relaxedUrlToFileSystemMapping =“true”.使用您已添加的属性,它可能看起来像这样：

<httpRuntime targetFramework="4.5" 
  requestPathInvalidCharacters="" 
  requestValidationMode="2.0" 
  relaxedUrlToFileSystemMapping="true" />

来自HttpRuntimeSection.RelaxedUrlToFileSystemMapping财产的文档：

Gets or sets a value that indicates whether the URL in an HTTP request
is required to be a valid Windows file path.

在ASP.NET运行时深处的某个地方,它尝试在处理请求之前将请求的URL转换为物理路径.如果物理路径无效,此设置似乎可以防止它爆炸.
