ICSharpCode.SharpZipLib.GZip.GZipInputStream与HTTP请求一起使用 [英] ICSharpCode.SharpZipLib.GZip.GZipInputStream Use with HTTP Request
问题描述
我正在使用.NET套接字类来编写Web客户端。当我来gzip编码的时候来了我的b $ b，我无法获得解码后的文本。
我找到了ICSharpCode.SharpZipLib来帮助，但是在使用它们的
示例代码，我一直遇到关于第一个字节的错误消息
不匹配。显然，它期望某个字节值为
的第一个字节，这使我认为我需要将编码的
主体从未编码的头部分开，然后发送只有GZIPInputStream的编码部分才能获得
。虽然我知道除法是由
空行确定的，但当我将它拆分为该行时（无论我是否在编码部分中包含
回车）我是仍然得到同样的错误。
有没有人能够使用该库来解码一个网页
有一个gzipped的身体？
谢谢！

我建议你将问题分成两半。你需要检查
：
1）你可以压缩一些然后解压缩它
2）你可以转移网络请求中没有丢失的二进制数据
我怀疑你的问题是在第二部分，但是你应该能够完全独立地工作第一部分。

我不确定你的帖子如何解决我的问题 - 你是否建议
我不喜欢为了使用
gzip库而且我的问题出在其他地方，我们需要将网页分成标题/正文吗？

我不需要将网页分成标题/正文以便使用
gzip库和我的问题在其他地方吗？
我建议你应该尽量确保你能成功
发送/接收任意二进制数据，以确定是否是'b
问题，或者是否是'gzipping'问题。

I am using the .NET socket class to program a web client. When I come
upon gzip encoded conent, I am having trouble getting the decoded text.
I have found the ICSharpCode.SharpZipLib to help, but in using their
sample code, I keep encountering an error message about the first byte
not matching. Clearly it is expecting a certain byte value as the
first byte, which leads me to think that I need to split the encoded
body away from the unencoded header, and send only the encoded part to
the GZIPInputStream. While I know that division is determined by a
blank line, when I split it over that line (whether I include the
carriage return in the encoded part or not) I still get the same error.
Has anyone been able to use that library for decoding a webpage that
has a gzipped body?
thanks!

I suggest you split the problem into two halves. You need to check
that:
1) You can zip something up and then unzip it
2) You can transfer binary data without loss in a web request
I suspect your problem is in the second part, but you should be able to
work on that entirely separately from the first part.

I''m not sure how your post addresses my issue - are you suggesting that
I don''t need to break the web page into header/body in order to use the
gzip library and that my problem is elsewhere?

I''m suggesting that you should try to make sure you can successfully
transmit/receive arbitrary binary data to work out whether that''s the
problem or whether it''s the gzipping that''s the problem.
