OKHttp throws an illegal state exception when I try to register a network response

Question

I put the following interceptor on my OkHttp client:

httpClient.addInterceptor(new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Response response = chain.proceed(chain.request());
        Log.d("Response", response.body().string());
        return response;
    }
    });

However, this does not work very well with Retrofit 2. It seems that you can only read the stream from the response once, and this may be the reason for the exception. I think retrofit is trying to parse the thread that the log has already analyzed. How do I get the answer? I'm currently trying to debug a very nasty and weird deviation from a json exception.

This is the exception stack trace:

I see that there are several interceptors on the stack, but I only ever add one, which is the one that throws the exception.

Answer 1

, :

@Override public Response intercept(Chain chain) throws IOException {
  Response response = chain.proceed(chain.request());
  ResponseBody body = response.body();
  String bodyString = body.string();
  MediaType contentType = body.contentType();
  Log.d("Response", bodyString);
  return response.newBuilder().body(ResponseBody.create(contentType, bodyString)).build();
}
