在Java中分块的http解码？ [英] Chunked http decoding in java?

问题描述

我正在解码http数据包。
我遇到了一个大块问题的问题。
当我收到一个http数据包时，它有一个标题和正文。
当transefer-encoding被分块时我不知道该怎么办？

I am decoding http packets. And I faced a problem that chunk problem. When I get a http packet it has a header and body. When transefer-encoding is chunked I don't know what to do ?

是否有一个有用的API或类用于在JAVA中对数据进行dechunk？

Is there a useful API or class for dechunk the data in JAVA ?

如果有人经历过http解码，请告诉我一个怎么做的方法？

And if someone , experienced about http decoding , please show me a way how to do this ?

推荐答案

使用完整的HTTP客户端，例如 Apache HttpComponents Client 或仅使用Java SE提供了 java.net .URLConnection （这里的迷你教程）。两者都完全透明地处理它，并为您提供正常 InputStream 。 HttpClient反过来还附带一个 ChunkedInputStream 你只需用。装饰你的 InputStream 。

Use a fullworthy HTTP client like Apache HttpComponents Client or just the Java SE provided java.net.URLConnection (mini tutorial here). Both handles it fully transparently and gives you a "normal" InputStream back. HttpClient in turn also comes with a ChunkedInputStream which you just have to decorate your InputStream with.

如果你真的坚持为这个库增加一个库，那么我建议你创建一个类 ChunkedInputStream扩展InputStream 并相应地写入逻辑。您可以在此维基百科文章中找到有关如何解析它的更多详细信息。

If you really insist in homegrowing a library for this, then I'd suggest to create a class like ChunkedInputStream extends InputStream and write logic accordingly. You can find more detail how to parse it in this Wikipedia article.
