HTTPClient - HTTP GET 因重定向 URL 中的 # 锚点而损坏
这有点奇怪。我正在使用 HTTPClient 4.1.2，似乎只要它发现 URL 中包含“#”之类的内容，它就会对 URL 中的 # 进行完整获取。
例如，尝试获取 URL http://stks.co/eWt 将重定向到 URL http://news.ichinastock.com/2011/10/jack-ma-阿里巴巴已准备好 200 亿美元收购 yahoo/#.Tpw-xG61XjU.twitter。现在这个 URL 已上线，但问题是 HTTPClient 发送了一个 URI 设置为 URI 的 get 请求：/2011/10/jack-ma-alibaba-has-prepared-20-billion-to-acquire-yahoo /#.Tpw-xG61XjU.twitter 这会导致服务器发回 404 页面未找到。
查看IE、Firefox和cURL发送的GET，它们都去掉了URI末尾的#...，因此例如cURL GET请求URI设置为URI：/2011/10/jack -ma-alibaba-has-prepared-20-billion-to-acquire-yahoo/ - 所有 #... 已被删除。这与 http://stks.co/eWt 的入口 URL 完全相同。
作为测试，将此原始 URL 发送到 HTTPClient（即 HttpGet httpget = new HttpGet("http://news.ichinastock.com/2011/10/jack-ma-alibaba-has-prepared-20-billion- to-acquire-yahoo/#.Tpw-xG61XjU.twitter");) 给出相同的 404 未找到结果。
所以问题是 HTTPClient 中是否有任何设置可以设置，以便可以从 URL 中自动删除尾随 #... 之类的内容。或者我该如何手动从 URL 中删除它（请记住，我还需要捕获所有重定向 URL）？
This is a bit of a weird one. I'm using HTTPClient 4.1.2, and it seems that whenever it finds are URL with something like a '#' in it, it does a full get with the # in the URL.
For example, trying to get the URL http://stks.co/eWt will redirect to the URL http://news.ichinastock.com/2011/10/jack-ma-alibaba-has-prepared-20-billion-to-acquire-yahoo/#.Tpw-xG61XjU.twitter. Now this URL is live, but the problem is the HTTPClient sends a get request with the URI set to URI: /2011/10/jack-ma-alibaba-has-prepared-20-billion-to-acquire-yahoo/#.Tpw-xG61XjU.twitter which causes the server to send back a 404 page not found.
Looking at the GET sent by IE, Firefox and cURL, they all strip out the #... from the end of the URI, so for example the cURL GET request URI is set as URI: /2011/10/jack-ma-alibaba-has-prepared-20-billion-to-acquire-yahoo/ - all the #... have been removed. This is for the exact same entry URL of http://stks.co/eWt.
As a test, sending this raw URL into HTTPClient (i.e. HttpGet httpget = new HttpGet("http://news.ichinastock.com/2011/10/jack-ma-alibaba-has-prepared-20-billion-to-acquire-yahoo/#.Tpw-xG61XjU.twitter");) gives the same 404 not found result.
So the question is are there any settings in HTTPClient that can be set so that things like the trailing #... can be auto removed from URLs. Or how would I go about manually removing this from URLs (remember that I would need to capture all redirect URLs as well)?

听起来他们的网络服务器坏了。 URI 规范规定，URI 的路径部分以数字符号 (#) 结尾。如果 Web 服务器考虑路径的 # 部分之后的任何内容，则它不遵循 URI 规范。
我测试了一些流行的Web服务器，它们都正确解析这些URI，忽略数字符号后面的部分。
我不虽然有任何好的解决方法建议，但至少现在你知道该责怪谁了。
It sounds like their web server is broken. The URI specification says that a number sign (#) terminates the path portion of the URI. If a web server considers anything after a # part of the path, it is not following the URI specification.
I tested a few popular web servers, and they all parse these URIs correctly, ignoring the portion after the number sign.
I don't have any good suggestions for a workaround though. But at least now you know who to blame.
注意： 哈希（以及哈希）之后的所有字符串都不会发送到服务器。 URL 中的哈希值是供浏览器使用的，而不是供服务器使用的。
Note: All strings coming after the hash (and the hash) won't be sent to a server. The hash in URL's is meant for browsers to work with and not a server.
