How can I sign in user of devise in grape?

Question

I use Grape to implement an API service of my app. But how can I call devise method sign_in in Grape?

Please look into this http://stackoverflow.com/questions/26623980/user-authentication-with-grape-and-devise — rick, Apr 27 '15 at 14:29
@rick , thanks. But I do not want to use token. And MY QUESTION IS how to auth user with username and password, which is before generating token. — WildCat, Apr 27 '15 at 14:31

In the Grape API base

# Enable session middleware for auth: https://stackoverflow.com/a/35428068/2771889
use ActionDispatch::Session::CookieStore
helpers do
  def session
    env['rack.session']
  end
end

The API

helpers Devise::Controllers::SignInOut

resource :users do
  # ...
end

Note that this adds the Session layer to the API which will cause some overhead that Grape by default would avoid. For a full auth solution see: https://stackoverflow.com/a/70683351/2771889

You need to write API which will post user_name & password and return user toke in API response

As

http://localhost:3000/api/v0/auth/sign_up

POST parameter

user[email]=p@p.com
user[password]=p123

In AuthController

def sign_up
   #create user and user token 
   render json: { token: <generated user token>}  
end

You migth need to write similar api for sign_in as well Use this token for subsequent API call to authorize user

I mean that I want to use helpers of Devise instead of mine. – WildCat Apr 28 '15 at 07:03
