如何指定Get-Request编码(Retrofit + OkHttp)

import okhttp3.Interceptor;
import okhttp3.Request;
import okhttp3.Response;

public class EncodingInterceptor implements Interceptor {
    private static final String HEADER_NAME = "Accept-Encoding";
    private static final String HEADER_VALUE = "gzip";

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request originalRequest = chain.request();
        Request modifiedRequest = originalRequest.newBuilder()
                .header(HEADER_NAME, HEADER_VALUE)
                .build();
        return chain.proceed(modifiedRequest);
    }
}

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(new EncodingInterceptor())
        .build();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .client(client)
        .build();
