How to get Retrofit success response status codes

Question

I am not able to get success response status code from response like 200,201.. etc. As we can easily get error codes from RetrofitError class like error.i

Answer 1

You can get the status code in success() just like you do it in failure()

@Override
public void success(Object object, Response response) {
    response.getStatus() // returns status code integer
}

Since you have a Response object in success callback as response.getStatus()

EDIT

I assume you are using okhttp with retrofit.

okhttp has a powerful tool called Interceptor

You can catch the response before retrofits Callback and get status code from the response:

OkHttpClient client = new OkHttpClient();
client.interceptors().add(new  Interceptor(){
    @Override 
    public Response intercept(Chain chain) throws IOException{

    Request request = chain.request();
    Response response = chain.proceed(request);
    response.code()//status code
    return response;

});

// then add it to you Restclient like this:
restAdapter = new RestAdapter.Builder()
                .setEndpoint(URL_SERVER_ROOT)
                .setClient(new OkClient(client))  //plus your configurations       
                .build();

As per Retrofit 2.0.2, the call is now

@Override
public void onResponse(Call<YourModel> call, Response<YourModel> response) {
    if (response.code() == 200) {
       // Do awesome stuff
    } else {
       // Handle other response codes
    }
}

Hope it helps someone :-)

EDIT: Many apps could also benefit from just checking for success (response code 200-300) in one clause, and then handling errors in other clauses, as 201 (Created) and 202 (Accepted) would probably lead to the same app logic as 200 in most cases.

@Override
public void onResponse(Call<YourModel> call, Response<YourModel> response) {
    if (response.isSuccessful()) {
       // Do awesome stuff
    } else if (response.code() == 401) {
       // Handle unauthorized
    } else {
       // Handle other responses
    }
}

Answer 3

i achieved it by following codes:

public abstract class BaseCallBack<T> {

    public abstract void onSuccess(Response<T> response);
    public abstract void onFailure(Response<T> response);
}

public abstract class SuccessCallback<T> extends BaseCallBack<T> implements Callback<T>{


    @Override
    public void onResponse(Call<T> call, Response<T> response) {

        if(response.code()>= 400 && response.code() < 599){
             onFailure(response);
        }
        else {
            onSuccess(response);
        }

    }

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

    }

    @Override
    public void onSuccess(Response<T> response) {

    }

    @Override
    public void onFailure(Response<T> response) {

    }
}

When the rest api returns 400 etc then the onFailure method will be call by default. If you wanna do something onsuccess:(when returns 200 etc)

 ServiceConnector.api.getHomePage().enqueue(new SuccessCallback<Void>() {
        @Override
        public void onSuccess(Response<Void> response) {
            super.onSuccess(response);
        }
    });
