Android Rest Api Post 400 bad request

Question

I'm working on an app that will send a password to the server to check if it's correct, the server will return 0,1,2,3 representing different statuses I'm not sure where this 400 bad request is coming from. I've called the server and received the json file but I'm suspecting it's how I parsed it? Any help is greatly appreciated.

AN UPDATE

an update. I realize part of the mistake here is that I'm trying to send a string without converting it to a JSON file first. That is why I've been receiving "status:0" which stands for an error occurred. I've converted my string into a RegisterRequest object which contains a string variable. Now I'm receiving status 2 which stands for incorrect password. However my bad request 400 still remains. PLEASE any help or suggestion will be very helpful to me

@Headers("Content-Type: application/json")
@POST("removed/{id}")
RegisterResponse registerEvent(
    @Path("id") int ID, 
    @Body RegisterRequest password
) throws NetworkException;

RegisterResponse class:

public class RegisterResponse {
    public String status;
}

RegisterRequest class

public class RegisterRequest {

    String passcode ;

    public RegisterRequest(String passcode)
    {
        this.passcode=passcode;
    }
}

call to server:

try {
    RegisterResponse response = NetworkHelper.makeRequestAdapter(this)
               .create(testApi.class).register(ID, pass);

        if(response.status=="1"||response.status=="3")
        {
            return true;
        }
        else
            return false;
    } catch (NetworkException e) {
        e.printStackTrace();
    }
   return false;
}

Make Request Adapter

private static RestAdapter.Builder makeRequestAdapterBuilder(final Context context, ErrorHandler errorHandler, String dateTimeFormat)
    {
        RequestInterceptor requestInterceptor = new RequestInterceptor()
        {
            @Override
            public void intercept(RequestInterceptor.RequestFacade request)
            {
                request.addHeader("Authorization", AppPrefs.getInstance(context).getSessionToken());
            }
        };

        Gson gson = new GsonBuilder().setDateFormat(dateTimeFormat).create();
        GsonConverter gsonConverter = new GsonConverter(gson);

        RestAdapter.Builder builder = new RestAdapter.Builder()
                .setRequestInterceptor(requestInterceptor).setConverter(gsonConverter)
                .setLogLevel(RestAdapter.LogLevel.FULL).setLog(new AndroidLog("Boom!"))
                .setEndpoint(BASE_URL);

        if(errorHandler != null)
        {
            builder.setErrorHandler(errorHandler);
        }

        if(instance == null)
        {
            instance = new OkClient(makeTimeoutClient(READ_TIMEOUT, CONNECT_TIMEOUT));
        }
        builder.setClient(instance);

        return builder;
    }

Answer 1

I've figured it out. I was handling the wrong exception and the API was returning 400 instead of 401 for senting the wrong passcode. I've changed my call to server network exception error to a exception error.

Thank you everyone for your help.

Answer 2

You have

 @Headers("Content-Type: application/json")
 @POST("removed/{id}")
 RegisterResponse registerEvent(@Path("eventID") int eventID, @Body RegisterRequest password)throws NetworkException;

Note that you call id the parameter (in the @POST annotation) but then in the parameter you use @Path("eventID").

Try changing your code to

 @Headers("Content-Type: application/json")
 @POST("removed/{eventID}")
 RegisterResponse registerEvent(@Path("eventID") int eventID, @Body RegisterRequest password)throws NetworkException;
