Question

当点击此url时，答案是System.NotSupportedException

http://localhost/missingcontroller/missingaction/503/page:10

这是ASP.NET MVC 3中的错误吗？知道怎么解决吗？

System.NotSupportedException：不支持给定路径的格式。

这不是重复

Using a colon (:) in a url with ASP.NET/IIS

首先这个问题不重复。我不是试图在网址中使用“：”，而是处理来自机器人的电话，这些机器人正在收集网站，有时在网址中使用“：”。

正确答案

正确的答案埋在StringExpressionSet.CanonilizePath方法中：

internal static string CanonicalizePath(string path, bool needFullPath)
{
    if (path.IndexOf('~') != -1)
    {
        string text = null;
        StringExpressionSet.GetLongPathName(path, JitHelpers.GetStringHandleOnStack(ref text));
        string arg_21_0 = (text != null) ? text : path;
        path = arg_21_0;
    }
    if (path.IndexOf(':', 2) != -1)
    {
        throw new NotSupportedException(Environment.GetResourceString("Argument_PathFormatNotSupported"));
    }
    if (!needFullPath)
    {
        return path;
    }
    string fullPathInternal = Path.GetFullPathInternal(path);
    if (path.EndsWith(StringExpressionSet.m_directorySeparator + ".", StringComparison.Ordinal))
    {
        fullPathInternal = ((!fullPathInternal.EndsWith(StringExpressionSet.m_directorySeparator)) ? (fullPathInternal + StringExpressionSet.m_directorySeparator + ".") : (fullPathInternal + "."));
    }
    return fullPathInternal;
}

看看这一行，你就会明白没有补丁就无法处理这些网址......

if (path.IndexOf(':', 2) != -1)
     throw new NotSupportedException(Environment.GetResourceString("Argument_PathFormatNotSupported"));

CanonicalizePath阻止“：”出现在url中的任何位置，并且无法替换此方法或其中一种调用方法。

一种解决方案可能是在global.asax Application_Error中处理此异常，提取英文字符串“不支持给定路径的格式”。如果异常是NotSupportedException类型，则重写url。但这可能会错误地处理其他真正的错误...

另一个解决方案可能是使用IIS重写模块（不是asp.net！）来动态替换传入URL中的任何“：”与另一个已知字符。
