如何使用改型将JSON作为字符串获取

Question

Please i'm new to retrofit and I've been stuck for weeks now, i tried getting my response as POJO class and end up with this error "Json document was not fully consumed", I've searched and also ask this question here and no one was able to help get out of this

Now i want to get my JSON as string from retrofit so i can do the conversion manually myself to my POJO class and dont know how to get the response JSON as string

Please i need your help I've been stuck with this for 3 weeks

Answer 1

just set the response type as String

@GET("api/offers")
Call<String> loadOffers(); 

instead of

@GET("api/offers")
Call<List<Offer>> loadOffers(); 

add this in your build.gradle file

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

and in public static Retrofit getRetrofitInstance() {

add these lines at the end of the function. the important part is the convert factories

if (retrofit == null) {
            retrofit = new retrofit2.Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .client(client)
                    .addConverterFactory(ScalarsConverterFactory.create())
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }

then you can fetch your data as JSON string

MyApi service = RetrofitClientInstance.getRetrofitInstance().create(MyApi.class);


        Call<String> callTypes = service.loadOffers();

        callTypes.enqueue(new Callback<String>() {
            @Override
            public void onResponse(Call<String> call, Response<String> response {                    
                String urJson  = response.body() ; 
               //  DO UR STUFF HERE
            }

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

            }
        });

I hope this will help you.

I hope this will help you in getting the response as string.

public interface RetrofitService{
        @GET("/users")
        Call<ResponseBody> listRepos();//function to call api
    }

    RetrofitService service = retrofit.create(RetrofitService.class);
    Call<ResponseBody> result = service.listRepos(username);
    result.enqueue(new Callback<ResponseBody>() {

    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());//convert reponse to string
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Hope this will work for you too.

Get the gson lib, it will do it for you. You Just have to creat an object which fit the json, and the lib will set the data in your object with you Json.
