Using Retrofit POST with different interface models in callback and body

Question

Here is my API end point:

http://192.168.1.22:8000/api/auth/login

I need to POST email and password to receive Token from server

Server Post response:

{
  "status": "ok",
  "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjIsImlzcyI6Imh0dHA6XC9cL21vbmV5bWF0Y2guYXBwOjgwMDBcL2FwaVwvYXV0aFwvbG9naW4iLCJpYXQiOjE0OTE0OTYzNDEsImV4cCI6MTQ5MTQ5OTk0MSwibmJmIjoxNDkxNDk2MzQxLCJqdGkiOiJhZmJhMDEzMzI5OWIwZmY0MzY3MTdlZDE4NmVkODI4OSJ9.bGlInsHHjdveeabz0j_36yICZtK32q1B9oNW44dk_x4"
}

here is my service Retrofit 2:

public interface ApiInterface {
    @POST("auth/login")
    Call<Login> authenticate(@Body User user);
}

here is my Login Model

public class Login {

    @SerializedName("status")
    @Expose
    private String status;
    @SerializedName("token")
    @Expose
    private String token;

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }
}

here is my User Model:

public class User {
@SerializedName("email")
@Expose
private String email;

@SerializedName("password")
@Expose
private String password;

public User(String email, String password) {
    this.email = email;
    this.password = password;
}
}

and this is how i call it in Activity

public void sendNetworkRequest(User user){
    Log.d(TAG,"send request fired");
    Retrofit.Builder builder = new Retrofit.Builder()
            .baseUrl("http://192.168.1.22:8000/api/")
            .addConverterFactory(GsonConverterFactory.create());
    Retrofit retrofit = builder.build();
    ApiInterface apiInterface = retrofit.create(ApiInterface.class);
    Call<Login> call = apiInterface.authenticate(user);

    call.enqueue(new Callback<Login>() {
        @Override
        public void onResponse(Call<Login> call, Response<Login> response) {
            Toast.makeText(LoginActivity.this, "wuhuuu"+ response.body().getToken(), Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFailure(Call<Login> call, Throwable t) {
            Log.d(TAG,"went wrong");
            Toast.makeText(LoginActivity.this, "something went wront"+t.toString(), Toast.LENGTH_LONG).show();
        }
    });
}

UPDATED: this is the Error I get:

com.google.gson.stream.malformedjsonexception use jsonreader.setlenient(true) to accept malformed at line 1column 1 $path

UPDATE Note: the email and password need to be sent in body form data.

Note: I can access the API from browser in Emulator so i guess it means there is something wrong in my logic or approach.

`.baseUrl("http://129.168.1.22:8000/api/")` did you find the mistake in url? — Murli Prajapati, Apr 06 '17 at 18:31
Your base url is `http://129.168.1.22:8000/api/`. But the error shows `192.168.1.22`. Is it somewhat wrong ? — Arkar Aung, Apr 06 '17 at 18:32
It may be possible that your received json is not correct. Please paste complete stack trace. — Murli Prajapati, Apr 06 '17 at 18:51
@MuraliPrajapati i have seen lots of people sending object in body. but in all examples they receive the callback with the same Model class they used in body. can that causing the issue ? PS. in PostMan i use Form Data to add the email and password. is adding to body as an object similar to `Form Data` or is there different way to do that? — Poorya, Apr 06 '17 at 19:12
Most of the time email and passwords are sent in auth headers. — Murli Prajapati, Apr 06 '17 at 19:18
refer this to send form data. http://stackoverflow.com/questions/37814857/retrofit-2-with-only-form-data — Murli Prajapati, Apr 06 '17 at 19:20
@MuraliPrajapati that was the solution. thanks. If you like to post as answer I'll mark it as answer — Poorya, Apr 06 '17 at 19:48

To send form data using Retrofit 2.0

@Multipart
@POST("url")
Call<PlanResponse> authenticate(@Part("email") RequestBody eamilValue, @Part("password") RequestBody passwordValue);

use it like this:

String email = "email@mail.com";
String password = "password";
RequestBody emailValue = RequestBody.create(MediaType.parse("text/plain"), emailValue);
RequestBody passwordValue= RequestBody.create(MediaType.parse("text/plain"), passwordValue);
Call<Login> call = apiInterface.authenticate(emailValue,passwordValue);

Using Retrofit POST with different interface models in callback and body
