How to get raw response and request using Retrofit 2.0

Question

I am trying to get the raw response using Retrofit2.0.2.

So far I tried to print the response using following line of code but it prints the address and not the exact response body.

Log.i("RAW MESSAGE",response.body().toString());

compile 'com.squareup.retrofit2:retrofit:2.0.2'

    Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();


            GitApi gitApi = retrofit.create(GitApi.class);

            Call<Addresses> call = gitApi.getFeed(user);

    call.enqueue(new Callback<Addresses>() {

                @Override
                public void onResponse(Response<Addresses> response, Retrofit retrofit) {
                    try {
                        mDisplayDetails.setText(response.body().getSuburbs().get(0).getText());

                    **Log.i("RAW MESSAGE",response.body().toString());**

                    } catch (Exception e) {
                        mDisplayDetails.setText(e.getMessage());
                    }
                    mProgressBar.setVisibility(View.INVISIBLE);

                }

                @Override
                public void onFailure(Throwable t) {
                    mDisplayDetails.setText(t.getMessage());
                    mProgressBar.setVisibility(View.INVISIBLE);

                }
            });

Answer 1

That's because it's already converted to an object by converter. To get the raw json, you need an interceptor on your Http Client. Thankfully you don't need to write your own class, Square already provide HttpLoggingInterceptor class for you.

Add this on your app-level gradle

compile 'com.squareup.okhttp3:logging-interceptor:3.5.0'

And use it in your OkHttpClient

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(interceptor).build();

Don't forget to change your HttpClient in Retrofit.

Retrofit retrofit = new Retrofit.Builder()
            .client(client)               
            .baseUrl("https://yourapi.com/api/")
            .build();

In the Log Cat you'll see the raw json response. Further information is available on Square's OkHttp github .

Caution!

Don't forget to remove Interceptors (or change Logging Level to NONE) in production! Otherwise people will be able to see your request and response on Log Cat.

Answer 2

Simply use:

Log.i("RAW MESSAGE", response.raw().body().string());

Or:

Log.i("RAW MESSAGE", response.body().string());

Answer 3

You have to use "ResponseBody" from okhttp3 in your call. Then, get "response.body().string()" to get the JSONObject as your server gives to you. It's a good way to catch errors if there are any errors parsing server response to your model object.

Answer 4

Guess you want to see the raw response body for debugging purpose. There are two ways to do this.

1. Using okhttp3.logging.HttpLoggingInterceptor as @aldok mentioned.

2. If you want to check some properties of the response object, or convert the json(response body) to POJO manually, you may want to do it like this:

Don't use the addConverterFactory while initializing the retrofit client, comment this line.

retrofit = new Retrofit.Builder()
                .client(client)
                .baseUrl(BASE_URL)
                //.addConverterFactory(GsonConverterFactory.create())
                .build();

Then consuming the response like this:

Call<ResponseBody> topRatedResponseCall = apiService.getTopRatedMoves(API_KEY);
    topRatedResponseCall.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            try {
                Log.d(LOG_TAG, response.body().string());
                int code = response.code();
                testText.setText(response.body().string());
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {

        }
    });

Hope this would help~
