An example of an AI chatbot conversation about Rails API token authentication.
How do I implement token authentication in a Rails API?
To implement token authentication in a Rails API, you can use the Devise gem along with the Devise Token Auth gem.
Can you explain how to set up Devise and Devise Token Auth?
Sure! First, add the gems to your Gemfile and run bundle install. Then, run the Devise generator to set up user authentication.
What are the steps to generate the token after user login?
After a successful login, the token is generated and sent in the response headers. You can access it using response.headers['access-token'].
How do I protect my API endpoints using this token?
You can use a before_action filter in your controllers to check for the presence of a valid token before allowing access to the endpoints.
