C# 我的网址编码有什么问题？

What's wrong with my url encoding?

提问by Boris Callens

In my asp.net mvc application I created the following link:

在我的 asp.net mvc 应用程序中，我创建了以下链接：

http://localhost:2689/en/Formula.mvc/351702++LYS+GRONN+5G+9%252f2++fds  

I get error 400 (bad request).

我收到错误 400（错误的请求）。

I think it blocks at the %25 (forward slash).
What am I doing wrong?

我认为它在 %25（正斜杠）处阻塞。
我究竟做错了什么？

--EDIT 3--
I tried not encoding anything at all but rather rely on the default encoding of Url.RouteUrl().
It seems that this doesn't encode the "/" for some reason.
If I encode it myself first, I end up with the doubel encoded %252f. This gives me a bad request for some reason.. Why?!

--EDIT 3--
我尝试不编码任何东西，而是依赖于 Url.RouteUrl() 的默认编码。
由于某种原因，这似乎没有对“/”进行编码。
如果我先自己编码，我最终会得到双倍编码的 %252f。出于某种原因，这给了我一个不好的要求..为什么？！

--EDIT 2--
I generated the last part of the URI as follows:

--EDIT 2--
我生成了 URI 的最后一部分，如下所示：

1. Take the id.toString
2. Take the HttpUtility.UrlEncode(name)
3. Take the HttpUtility.UrlEncode(code)
4. String.Format("{0}--{1}--{2}") with the values from the previous parts
5. Add it as a parameter to Url.RouteUrl()

1. 取 id.toString
2. 取 HttpUtility.UrlEncode(name)
3. 以 HttpUtility.UrlEncode(code)
4. String.Format("{0}--{1}--{2}") 与前面部分的值
5. 将其作为参数添加到 Url.RouteUrl()

After that my action gets this parameter again, splits it at -- and HttpUtility.Decode() the values back.

之后，我的操作再次获取此参数，将其拆分为 -- 和 HttpUtility.Decode() 返回值。

I do it this way because the two last parameters are optional, but functional parameters. IF they are defined in a previous step, they have to be carried along to the other pages.
Less abstract: A color can have multiple names, but if a user selected it by a particular name, it should be kept throughout all the other pages.

我这样做是因为最后两个参数是可选的，但功能参数。如果它们是在上一步中定义的，则必须将它们带到其他页面。
不那么抽象：一种颜色可以有多个名称，但如果用户通过特定名称选择它，则应在所有其他页面中保留它。

--EDIT 1--
It also looks like HttpUtility.UrlEncode() and Url.Encode() return different results :S

--EDIT 1--
看起来 HttpUtility.UrlEncode() 和 Url.Encode() 返回不同的结果：S

If I don't encode the "/", it acts as a separator=>no luck there. If I encode it with Url.Encode() I end up with %2F => Code 400 If I encode it with HttpUtility.UrlEncode() I end up with %25 => code 400

如果我不对“/”进行编码，它将充当分隔符=> 那里没有运气。如果我用 Url.Encode() 对其进行编码，我会得到 %2F => Code 400 如果我用 HttpUtility.UrlEncode() 对其进行编码，我会得到 %25 => 代码 400

Because 400 doesn't even let it through to asp.net-mvc, the route debugger is of no use :(

因为 400 甚至不让它通过 asp.net-mvc，所以路由调试器没有用:(

I was there a couple of days ago. If you can accept unreadable route-values in the URL try this: URL-encoded slash in URL

几天前我在那里。如果您可以接受 URL 中不可读的路由值，请尝试以下操作： URL-encoded slash in URL

I haven't looked too much at the encoding - but note that if this is to be storedsomewhere (or acted upon in some way), then a POST would be more appropriate. If the text on the right is actually representative of the data with id 351702 (a vanity url, much like /665354/whats-wrong-with-my-url-encoding), then you should humanize the text. Much as the spaces have been removed from the above. It is also common to have this as a separate level in the route that is simply discarded.

我没有过多研究编码 - 但请注意，如果将其存储在某处（或以某种方式进行操作），那么 POST 会更合适。如果右侧的文本实际上代表了 id 为 351702 的数据（一个虚 url，很像/665354/whats-wrong-with-my-url-encoding），那么您应该对文本进行人性化。就像上面的空格已被删除一样。将此作为路由中的单独级别并被简单丢弃的情况也很常见。

Generally, MVC urls should be comprehensible.

一般来说，MVC url 应该是可以理解的。

%25is actually encoded "%", so %252fis encoded "%2f".

%25实际上编码为“%”，因此%252f编码为“%2f”。

%2f(encoded "/") is not allowed in URL unless you explicitly allow it in webserver's configuration.

%2f除非您在网络服务器的配置中明确允许，否则 URL 中不允许使用（编码为“/”）。

You can't use a forward slash as a value in the URL. Here is a nice post about creating browser and SEO friendly URLS => http://www.dominicpettifer.co.uk/displayBlog.aspx?id=34

您不能使用正斜杠作为 URL 中的值。这是一篇关于创建浏览器和 SEO 友好 URLS 的好帖子 => http://www.domincpettifer.co.uk/displayBlog.aspx?id=34

[Edit] Whenever you create a route you associate it with a URL pattern (The default pattern is {controller}/{action}/{id}). And in this url pattern you are supposed to use the forward slash to separate different tokens. Hope that helps

[编辑] 每当您创建路由时，您都会将其与 URL 模式相关联（默认模式是 {controller}/{action}/{id}）。在这个 url 模式中，你应该使用正斜杠来分隔不同的标记。希望有帮助
