Retrofit callback get response body

I am testing Retrofit to compare it with Volley and I am struggling to get the response from my requests. For example, I do something like this:

RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint("http://localhost:8080")
            .build();

MyService service = restAdapter.create(MyService.class);
service.getToto("toto", new Callback<Toto>() {

        @Override
        public void success(Toto toto, Response response) {
            // Try to get response body
            BufferedReader reader = null;
            StringBuilder sb = new StringBuilder();
            try {
                reader = new BufferedReader(
                    new InputStreamReader(response.getBody().in()));
                String line;
                try {
                    while ((line = reader.readLine()) != null) {
                        sb.append(line);
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            String result = sb.toString();
        }

        @Override
        public void failure(RetrofitError error) {}
    });

It works, the object toto is set, but for testing purposes, I also want to display the JSON response returned by the server.

So I am trying to read the InputStream from response.getBody() which is a TypedInputStream. Unfortunately, I always get an IOException : Stream is closed.

I tried to use the Utils class from Retrofit but I get the same IOException error.

Inside callback's angle brackets write "Response" and then extract the stream from this response.

service.getToto("toto", new Callback<Response>() {
    @Override
    public void success(Response result, Response response) {

        //Try to get response body
        BufferedReader reader = null;
        StringBuilder sb = new StringBuilder();
        try {

            reader = new BufferedReader(new InputStreamReader(result.getBody().in()));

            String line;

            try {
                while ((line = reader.readLine()) != null) {
                    sb.append(line);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }


        String result = sb.toString();
    }

    @Override
    public void failure(RetrofitError error) {

    }
});

Before Retrofit 2.0

   String bodyString = new String(((TypedByteArray) response.getBody()).getBytes());

Retrofit 2.0

 String  bodyString = new String(response.body().bytes());

If you set .setLogLevel(RestAdapter.LogLevel.FULL) on the RestAdapter that you use to create the service you should get the raw JSON response output in the debug console.

RestAdapter restAdapter = new RestAdapter.Builder()
    .setServer("http://my_lovely_api.com")
    .setLogLevel(RestAdapter.LogLevel.FULL)
    .build();

mService = restAdapter.create(MyService.class);

If you want to do something different with this raw response you can still use the code you have in your success block to create a JSON string assuming that you keep the LogLevel.FULL in the setLogLevel method, if not then it won't parse the InputStream from response.getBody().in() as it's already been read and closed.
