如何使用Java以适当的编码检索HTML页面？ [英] How to retrieve HTML page in proper encoding using Java?

问题描述

如何在页面编码中使用HTML页面读取HTTP流？

How can I read HTTP stream with HTML page in page's encoding?

这是我用来获取HTTP流的代码片段。 InputStreamReader 有编码可选参数，但我对获取它的方法一无所知。

Here is a code fragment I use to get the HTTP stream. InputStreamReader has the encoding optional argument, but I have no ideas about the way to obtain it.

URLConnection conn = url.openConnection();
InputStream is = conn.getInputStream();
BufferedReader d = new BufferedReader(new InputStreamReader(is));

推荐答案

检索网页是一个相当复杂的过程。这就是为什么存在诸如 HttpClient 之类的库的原因。我的建议是，除非你有其他令人信服的理由，否则请使用HttpClient。

Retrieving a Webpage is a reasonably complicated process. That's why libraries such as HttpClient exist. My advice is that unless you have a really compelling reason otherwise, use HttpClient.
