Retrofit and OkHttp gzip decode
提问by Simon Tenbeitel
The REST service I want to consume answers as a gzipped encoded JSON. It provides the Content-Encoding: gzip, but my OkHttp does not encode it to readable text, so the JSON converter throws an exception.
我想将答案作为 gzip 编码的 JSON 使用的 REST 服务。它提供了Content-Encoding: gzip，但我的 OkHttp 没有将其编码为可读文本，因此 JSON 转换器会引发异常。

According to Jake Whartons commentthe Content-Encoding: gzipHeader should tell OkHttp to decode the body.
根据Jake Whartons 的评论， Content-Encoding: gzipHeader 应该告诉 OkHttp 解码正文。
The code for creating the RestAdapter is:
创建 RestAdapter 的代码是：
final RestAdapter adapter = new RestAdapter.Builder()
.setEndpoint(baseUrl)
.setClient(new OkClient(new OkHttpClient()))
.setConverter(new GsonConverter(gson))
.setLogLevel(RestAdapter.LogLevel.FULL)
.build();
service = adapter.create(RaplaService.class);
The gradle dependencies are:
gradle 依赖项是：
compile 'com.squareup.retrofit:retrofit:1.9.0'
compile 'com.squareup.okhttp:okhttp:2.6.0'
The method in my ServiceInterface:
我的 ServiceInterface 中的方法：
@Headers({
"Accept-Encoding: gzip, deflate",
"Content-Type: application/json;charset=utf-8",
"Accept: application/json"
})
@GET("/events")
List<Event> getEvents(@Header("Authorization") String token, @Query("resources") String resources, @Query("start") String start, @Query("end") String end);

Replace this:
替换这个：
@Headers({
"Accept-Encoding: gzip, deflate",
"Content-Type: application/json;charset=utf-8",
"Accept: application/json"
})
With this:
有了这个：
@Headers({
"Content-Type: application/json;charset=utf-8",
"Accept: application/json"
})
When you provide your own Accept-Encodingheader you're instructing OkHttp that you want to do your own decompression. By omitting it, OkHttp will take care of both adding the header and the decompression.
当您提供自己的Accept-Encoding标头时，您是在指示 OkHttp 您要进行自己的解压。通过省略它，OkHttp 将负责添加标头和解压。
