What to return in a login when the user does not exist or exists but the password is wrong?, using Retrofit

  • 772

Good morning everyone.

I am faced with the following situation:

I am performing a login using Retrofit for the requests, these return the user's data when successfully logged in through a json.

I am doing the validation through php, the problem arises when instead of json I return an error message, for example when the username or password are incorrect, retrofit returns these errors to me as

com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $

since the error messages are of the type, "Wrong password" , "User not registered"

The question is: how can I receive these login errors without retrofit taking them as json malformation errors?

I remain attentive, in advance thank you very much

    The problem is that retrofit understands that everything it receives will always be a json. To solve the problem I recommend that you put the error messages inside a json as well.

    for instance:

    {"error":401,"description":"Contraseña incorrecta"}
