HttpURLConnection不解压缩Gzip [英] HttpURLConnection not decompressing Gzip

问题描述

我正在尝试在Gingerbread + Android设备上使用HttpURLConnection，但gzip编码遇到问题.根据文档

I'm trying to use HttpURLConnection on Gingerbread+ Android devices and am having trouble with the gzip encoding. According to the documentation

"在Gingerbread中，我们添加了透明的响应压缩. HttpURLConnection会自动将此标头添加到传出中 请求，并处理相应的响应:

"In Gingerbread, we added transparent response compression. HttpURLConnection will automatically add this header to outgoing requests, and handle the corresponding response:

接受编码:gzip"

Accept-Encoding: gzip"

问题是这实际上没有发生.完全不会添加Accept-Encoding:gzip标头.如果我手动添加它，那么我希望它的解压缩部分可以通过connection.openInputStream()来自动返回GZipInputStream，但它仅返回一个普通的InputStream.

The problem is that this is not actually happening. The Accept-Encoding: gzip header is not getting added at all. If I add it manually, I would then expect the decompressing part of it to work by connection.openInputStream() to automatically return a GZipInputStream but it just returns a plain InputStream.

有人经历过吗?我还没有看到发生这种情况的任何帖子，所以非常奇怪.该项目是根据API 17编译的，因此应该不会出现问题，并且设备正在运行4.3.

Has anyone experienced this? I havent seen any posts of this happening so its very odd. The project is compiled against API 17 so that shouldnt be a problem and the device is running 4.3.

谢谢.

推荐答案

我遇到了同样的问题，并且与 HTTPS 有关.如果您致电:

I had the same problem and it was related to HTTPS. If you call:

URL url = new URL("https://www.example.com");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();

您实际上获得了一个不会自动处理gzip的HttpsURLConnection(HttpURLConnection的子类)的实例. 在这种情况下，您可以:

you actually get an instance of HttpsURLConnection (a subclass of HttpURLConnection) that does NOT handle gzip automatically. In those cases you can:

conn.setRequestProperty("Accept-Encoding", "gzip");
...
InputStream inStream = new GZIPInputStream(conn.getInputStream());
