％20后斜线后面更多的数据会导致ASP.NET MVC 3路由失败？ [英] %20 followed by slash followed by more data causes ASP.NET MVC 3 routing to fail?

问题描述

在20％出现在PARAMATERS URL之间的人物，我的MVC路由停止考虑的字符串。

这是为什么，以及如何我走近我的URL处理％20字符？

为例网址

 的http：//本地主机：40494 / ListContents /删除/航空自卫队％20 / 5430f394 ...公众的ActionResult删除（字符串DNSNAME，的Guid ID）
{...}routes.MapRoute（
    删除，//路线名称
    ListContents /删除/ {} DNSNAME /（编号），// URL带参数
     新{控制器=ListContents，行动=删除} //参数默认
      ）;
 

然而
下面两个网址，做工精细

 的http：//本地主机：40494 / ListContents /删除/航空自卫队％20SOMETHING_HERE / 5430f394 ...HTTP：//本地主机：40494 / ListContents /删除/％20asdf / 5430f394-946c-4f82-ac13-9d5efafe9127
 

解决方案

如果一个空的空间是下一个斜线之前的URL的任何部分的结尾，它抛出一个 HttpException 在由MVC处理，你会得到一个HTTP 404响应 System.Web.Util.FileUtil.CheckSuspiciousPhysicalPath（）方法。

您可以通过检查中的复选框扔验证一下：

1. 的Visual Studio


2. 调试


3. 例外


4. 公共语言运行库异常

通常你不应该有空格在您的网址。我个人格式化我的网址，所有的空间变成一个破折号（ - ）。

When the characters %20 appears in between paramaters a url, my MVC routing stops considering that a string.

Why is that, and how can I approach handling "%20" characters in my URL?

Example URL

http://localhost:40494/ListContents/Delete/asdf%20/5430f394...

public ActionResult Delete(string DNSName, Guid id)
{...}

routes.MapRoute(
    "Delete", // Route name
    "ListContents/Delete/{DNSName}/{id}", // URL with parameters
     new { controller = "ListContents", action = "Delete" } // Parameter defaults
      );

However Both the following URLs work fine

http://localhost:40494/ListContents/Delete/asdf%20SOMETHING_HERE/5430f394...

http://localhost:40494/ListContents/Delete/%20asdf/5430f394-946c-4f82-ac13-9d5efafe9127

解决方案

If an empty space is at the end of any section of the URL before the next slash, it throws a HttpException in the System.Web.Util.FileUtil.CheckSuspiciousPhysicalPath() method which is handled by MVC and you'll get a HTTP 404 response.

You can verify that yourself by checking the checkbox for Throw in:

1. Visual Studio
2. Debug
3. Exceptions
4. Common Language Runtime Exceptions

Generally you should not have empty spaces in your URLs. I personally format my urls, that all spaces becomes a dash (-).
