Question

REST服务我想以gzip编码的JSON格式使用答案。它提供Content-Encoding: gzip，但我的OkHttp不会将其编码为可读文本，因此JSON转换器会抛出异常。

---> HTTP GET https://rapla.dhbw-karlsruhe.de/rapla/events?resources=%5B%27rc85dbd6-7d98-4eb7-a7f6-b867213c73d8%27%5D&start=2015-09-01&end=2015-12-31

根据Jake Whartons comment，Content-Encoding: gzip标题应该告诉OkHttp对身体进行解码。

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);

gradle依赖项是：

compile 'com.squareup.retrofit:retrofit:1.9.0'
compile 'com.squareup.okhttp:okhttp:2.6.0'

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);

替换它：

@Headers({
    "Accept-Encoding: gzip, deflate",
    "Content-Type: application/json;charset=utf-8",
    "Accept: application/json"
})

有了这个：

@Headers({
    "Content-Type: application/json;charset=utf-8",
    "Accept: application/json"
})

当您提供自己的Accept-Encoding标题时，您指示OkHttp您想要进行自己的解压缩。通过省略它，OkHttp将负责添加标题和解压缩。

改造和OkHttp gzip解码
