如何编码包含哈希的路径？ [英] How to encode a path that contains a hash?

问题描述

你如何正确编码的路径，包括一个散在其中（＃）？注意哈希不是片段（？书签）指示，但路径名的一部分

How do you properly encode a path that includes a hash (#) in it? Note the hash is not the fragment (bookmark?) indicator but part of the path name.

例如，如果有这样的路径：

For example, if there is a path like this:

http://www.contoso.com/code/c#/somecode。 CS

这会导致问题，当您例尝试做到这一点：

It causes problems when you for example try do this:

Uri myUri = new Uri("http://www.contoso.com/code/c#/somecode.cs");

这似乎是它解释哈希的片段指标。

It would seem that it interprets the hash as the fragment indicator.

感觉不对％，23手动替换＃。是否应更换有其他字符？
有在乌里一些逃脱的方法和HttpUtility但没有似乎做的伎俩。

It feels wrong to manually replace # with %23. Are there other characters that should be replaced? There are some escaping methods in Uri and HttpUtility but none seem to do the trick.

推荐答案

做了一些更多的挖朋友，发现重复的问题，对Java：
HTTP URL地址编码在Java中

Did some more digging friends and found a duplicate question for Java: HTTP URL Address Encoding in Java

但是，.NET的乌里类不提供我们所需要的构造，但在 UriBuilder 。确实

However, the .Net Uri class does not offer the constructor we need, but the UriBuilder does.

所以，为了构建一个适当的URI所在的路径包含非法字符，这样做：

So, in order to construct a proper URI where the path contains illegal characters, do this:

// Build Uri by explicitly specifying the constituent parts. This way, the hash is not confused with fragment identifier
UriBuilder uriBuilder = new UriBuilder("http", "www.contoso.com", 80, "/code/c#/somecode.cs");

Debug.WriteLine(uriBuilder.Uri);
// This outputs: http://www.contoso.com/code/c%23/somecode.cs

注意它是如何做的不可以不必要逃脱URI的部分，并不需要转义（如：//部分），这是HttpUtility.UrlEncode的情况。这似乎是这个类的目的实际上是对URL的查询字符串/片断部分编码 - 而不是方案或主机名

Notice how it does not unnecessarily escape parts of the URI that does not need escaping (like the :// part) which is the case with HttpUtility.UrlEncode. It would seem that the purpose of this class is actually to encode the querystring/fragment part of the URL - not the scheme or hostname.
