OKHTTP GET and POST request return empty body message

I want to a upload file on my server and I've decided to try OKHTTP instead of my current method which is based on android own HTTP implementation and AsyncTask.

Anyway, I used OKHTTP and its asynchronous implementation (from its own recipes) but it returns an empty message (the request code is ok, the message is empty) in both GET and POST methods. Did I implement it wrong or is there anything else remained that I did not considered? In the meantime, I couldn't find a similar case except this which says used AsyncTask.

Here's the code:

Request request;
Response response;
private final OkHttpClient client = new OkHttpClient();
private static final String postman_url = "https://postman-echo.com/get?foo1=bar1&foo2=bar2";
String message_body;

public void Get_Synchronous() throws IOException
{
    request = new Request.Builder()
            .url(postman_url)
            .build();

    Call call = client.newCall(request);
    response = call.execute();

    message_body = response.toString();
    //assertThat(response.code(), equalTo(200));
}

public void Get_Asynchronous()
{
    request = new Request.Builder()
            .url(postman_url)
            .build();

    Call call = client.newCall(request);
    call.enqueue(new Callback() {
        public void onResponse(Call call, Response response)
                throws IOException
        {
            message_body = response.toString();
            
        }

        public void onFailure(Call call, IOException e)
        {
            
        }
    });
}

Edit: I catch the log on response:

onResponse: Response{protocol=h2, code=200, message=, url=https://postman-echo.com/get?foo1=bar1&foo2=bar2}

OK, for anyone who wants to receive an string from a call, response and response.messgage() don't provide that. To catch the response from your provider, you just need to call response.body().string() inside onResponse which returns the message inside your request.

But after all, Retrofit is a better choice if you want to receive a JSON file using .addConverterFactory(GsonConverterFactory.create(gson)).

If you still want to receive an string just use .addConverterFactory(ScalarsConverterFactory.create()) as explained here.
