推荐答案

看来，ASP.net不前，让冒号？在URL，即使它是连接codeD为％3A。

It seems that ASP.net does not allow colons before the '?' in an URL, even if it is encoded as %3A.

例如，这些将无法正常工作

For example, these won't work

http://foo.org/api/persons/foo:bar
http://foo.org/api/persons/foo%3abar

但这个工程：
http://foo.org/api/persons?id=foo%3abar

在所有案例中，我们希望ASP.NET MVC传递富：酒吧作为一个id参数，正确地去codeD。我只是MVC4测试这一点，它似乎工作。这是烦人，不接受问号之前的URL编码虽然，但我敢肯定有一个很好的理由。可能把一切都问号问号后面一个有效的URL和任何参数之前。

In all examples, we would expect ASP.NET MVC to pass "foo:bar" as an id argument, properly decoded. I just tested this with MVC4 and it seems to work. It is annoying that it doesn't accept the URL encoding before the question mark though, but I'm sure there is a good reason for it. Probably to keep everything before the question mark a valid URL and any arguments after the question mark.
