Capturing List response for a Retrofit Call with Json body

问题

All.

I am trying to use Retrofit to send raw json as a body in a POST Request to the server.

@POST("api/apps")
Call<List<GetApps>> getApp(@Body GetApps body);

I have built the model using jsontopojo for the responses that are coming back.

Inside my call, I have put the constructors and the getters and setters and also toString().

This is my retrofit call.

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

        APIService apiService = retrofit.create(APIService.class);

        Call<List<GetApps>> call = apiService.getApp();

        call.enqueue(new Callback<List<GetApps>>() {
            @Override
            public void onResponse(Call<List<GetApps>> call, Response<List<GetApps>> response) {
                List<GetApps> GetApps2 = response.body();


                Toast.makeText(getApplicationContext(),"success", Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onFailure(Call<List<GetApps>> call, Throwable t) {
                Toast.makeText(getApplicationContext(),"Failure", Toast.LENGTH_SHORT).show();


            }
        });

I am getting an error on this line :

Call<List<GetApps>> call = apiService.getApp();

It says getApp(getApps) cannot be applied to (); Not sure what should go into the ();

回答1:

You must pass GetApps object as parameter:

GetApps getApps = new GetApps();
//set all your data on getApps
//getApps.setYourData(yourData);
Call<List<GetApps>> call = apiService.getApp(getApps);

回答2:

You make request

@POST("api/apps")
Call<List<GetApps>> getApp(@Body GetApps body);

which will accept body that will append to URL.

just add body in getApp(@Body GetApps body); // accept JSON string as a parameter.

Happy coding!!

At the top of Post just add @FormEncodedUrl and pass a GetApp model as body ... Call<List<GetApps>> call = apiservice.getApp(getAppOne);
