What might cause an Empty retrofit response?-CodePudding

I have an API endpoint that is supposed to send a one-time password to a user email. I try it on postman and it works just fine. However it doesn't give any response in the code I am new to this, can anyone give me an answer. Here is my code...

// call to get OTP
public void makeApiCallForVerification(Context context, String email,String token){
    mApiServiceVerification = RetrofitInstance.getRetroClientWithToken(token).create(APIService.class);

    System.out.println("token is: "  token);
    mCallVerification = mApiServiceVerification.CheckUserVerification();
    
    mCallVerification.enqueue(new Callback<UserVerificationResponse>() {
        @Override
        public void onResponse(Call<UserVerificationResponse> call, Response<UserVerificationResponse> response) {
            mLiveDataVerification.postValue(response.body());
            LiveDatauserVerificationStatus.postValue(response.code());


           if(response.body() != null) {
                Log.d(TAG, "onResponse: "   response.body().toString());

              SweetAlertDialog dialog=  new SweetAlertDialog(context, SweetAlertDialog.SUCCESS_TYPE);
                        dialog.setTitleText("Verification Sent to \n"  email)
                        .setContentText("Check your Email Inbox")
                        .setNeutralButtonTextColor(Color.parseColor("#297545")).setCancelable(false);
                        dialog.show();
                try{

                    int OTP = response.body().getDataSentInEmail().getOtpNumber();
                    updateVerificationStatus( context,OTP,0);
                    OTPCodeLiveData.postValue(String.valueOf(OTP));
                    LiveDatauserVerificationStatus.postValue(0);

                }catch (Exception e){
                    Log.d(TAG, "onResponse: err " e.toString());
                    e.printStackTrace();
                }

        }

        }

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



            Log.d(TAG, "onFailure: "   t);
            System.out.println(call);
            LiveDatauserVerificationStatus.postValue(-1);
            ErrorLiveData.postValue(t.toString());
            Log.d(TAG, "onResponse: "   t.toString());

        }
    });
}

//on the Interface class

@Headers("Accept: application/json")
@GET("user/otp")
Call<UserVerificationResponse> CheckUserVerification();

CodePudding user response：

You can try it

 @Headers("Content-Type: application/json")

CodePudding user response：

Try changing APIService(interface) class like this("/" before user at @GET)

@Headers("Accept: application/json")
@GET("/user/otp")
Call<UserVerificationResponse> CheckUserVerification();
