Sending JSON in POST request with Retrofit2

Question

I\'m using Retrofit to integrate my Web services and I do not understand how to send a JSON object to the server using a POST request. I\'m currently stuck, here is my code:

Answer 1

i think you should now create a service generator class and after that you should use Call to call your service

PostInterface postInterface = ServiceGenerator.createService(PostInterface.class);
Call responseCall =
            postInterface.getStringScalar(requestBody);

then you can use this for synchronous request and get the body of response:

responseCall.execute().body();

and for asynchronous :

responseCall.enqueue(Callback);

refer to link provided below for complete walkthrough and how to create ServiceGenerator :
