Retrofit and OkHttp gzip decode

问题:

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.

According to Jake Whartons comment the Content-Encoding: gzip Header should tell OkHttp to decode the body.

The code for creating the RestAdapter is:

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:

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

The method in my ServiceInterface:

@Headers({         "Accept-Encoding: gzip, deflate",         "Content-Type: application/json;charset=utf-8",         "Accept: application/json" }) @GET("/events") List getEvents(@Header("Authorization") String token, @Query("resources") String resources, @Query("start") String start, @Query("end") String end);

Replace this:

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

With this:

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

When you provide your own Accept-Encoding header 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.
