What header should be used for sending GZIP compressed JSON from Android Client to Server?
提问by Gaurav Agarwal
This question is extension to the question here. I am using the code herereproduced below to GZIP compress a JSONObject.
这个问题是这里问题的延伸。我使用的代码在这里转载如下，以GZIP压缩JSONObject。
String foo = "value";
ByteArrayOutputStream baos = new ByteArrayOutputStream();
GZIPOutputStream gzos = null;
try {
gzos = new GZIPOutputStream(baos);
gzos.write(foo.getBytes("UTF-8"));
} finally {
if (gzos != null) try { gzos.close(); } catch (IOException ignore) {};
}
byte[] fooGzippedBytes = baos.toByteArray();
I am using a DefaultHttpClientto send this compressed JSONObject to server(the code is in my control).
我正在使用 aDefaultHttpClient将这个压缩的 JSONObject 发送到服务器（代码在我的控制之下）。

What header should I use in my request? I am using request.setHeader("Content-type", "application/json");for sending JSON to server?
我应该在我的request? 我request.setHeader("Content-type", "application/json");用于将 JSON 发送到服务器？

To inform the server that you are sending gzip-encoded data, send the Content-Encodingheader, not Accept-Encoding.
要通知服务器您正在发送 gzip 编码的数据，请发送Content-Encoding标头，而不是Accept-Encoding。

Thisanswer shows you that you need to set a header indicating that you are sending data compressed:
这个答案表明您需要设置一个标头，表明您正在发送压缩数据：
HttpUriRequest request = new HttpGet(url);
request.addHeader("Content-Encoding", "gzip");
// ...
httpClient.execute(request);
The answer also shows how to deal with the incoming compressed data.
答案还显示了如何处理传入的压缩数据。

Content-Type:application/json- tells what type of content data in the http callContent-Encoding: gzip- tells what compression being used.
Content-Type:application/json- 说明 http 调用中的内容数据类型Content-Encoding: gzip- 说明正在使用什么压缩。
application/jsonor text/xmlor other type can be compressed as gzip and sending to receiver and with Content-Typeheader only, receiver will identify the incoming data is of type json/xml/textand then convert back to object of type json/xml/text.
application/json或text/xml或其他类型可以压缩为 gzip 并发送到接收器并且Content-Type仅带有标头，接收器将识别传入数据的类型json/xml/text，然后转换回 json/xml/text 类型的对象。
With Content-Encodingheader only receiver will identify the incoming data is getting gzip compressed. Then receiver required to decompress the incoming data and use it.
Content-Encoding仅使用标头接收器将识别传入数据正在被 gzip 压缩。然后接收器需要解压缩传入的数据并使用它。
