Devise Authentication using cURL

This works for me :

curl -XPOST -v -H 'Content-Type: application/json' http://domain/api/v1/auth/sign_in -d '{"email": "email@domain.com", "password": "password" }

So I get back the response (something like below, only important part) :

< access-token: lW1c60hYkRwAinzUqgLfsQ< token-type: Bearer< client: W_xCQuggzNOVeCnNZbjKFw< expiry: 1426610121< uid: email@domain.com

Then I can validate the token, using the client and token previously obtained from the above request, I do it like this :

curl -XGET -v -H 'Content-Type: application/json' -H 'access-token: lW1c60hYkRwAinzUqgLfsQ' -H 'client: W_xCQuggzNOVeCnNZbjKFw' -H "uid: email@domain.com" http://domain/api/v1/auth/validate_token

The result :

{"success":true,"data":{"id":3,"provider":"email","uid":"email@domain.com","firstname":null,"lastname":null,"email":"email@domain.com"}}

I found that the login step needed to be wrapped in a user dictionary, viz:

curl -X POST -v -H 'Content-Type: application/json' \   http://somehost.com/users/sign_in -d \   '{"user" : {"email": "some_user@nowhereville.org", "password": "OpenSecret" }}'

This is Devise 3.5.4.
