WARNING: Can't verify CSRF token authenticity

问题:

I am right now developing web APIs with Ruby on Rails. When the Rails app receives POST request without any csrf token, the following error message shall happen. Because the app has no views.

WARNING: Can't verify CSRF token authenticity

So my question is how can I escape csrf token check safely in this case?

Thank you very much in advance.

回答1:

You can do this by adding

skip_before_filter  :verify_authenticity_token

to your controller. This way all incoming requests to the controller skips the :verify_authenticity_token filter.

回答2:

For rails 4 it should be

skip_before_action :verify_authenticity_token, only: [:one_or_two_actions_here]

Note that you should avoid skipping verify_authenticity_token on all actions of your controller, instead use the option only to skip only where you have to. See the docs
