设计策略有一个有效？方法被调用以确定是否应该启用该策略。这使您可以根据每个控制器/操作来控制可用的认证策略。

将其放在初始化器中：

  require'devise / strategies / base'
 require'devise / strategies / token_authenticatable'
 module Devise 
 module Strategies 
 class TokenAuthenticatable&lt ;验证
 def有效？ 
超级&& params [：controller] ==你的控制器& amp;& params [：action] ==your action
 end 
 end 
 end 
 end 
 

让我知道如果它有效。

I have an webapplication that uses devise database authentication for all the controllers, however I want to have one controller action where authentication is also done using a token. Can i use devise for this?

Devise strategies have a valid? method that is called to determine if the strategy should be enabled. This allows you to control available auth strategies on a per controller/action basis.

Put this in an initializer:

require 'devise/strategies/base'
require 'devise/strategies/token_authenticatable'
module Devise
  module Strategies
    class TokenAuthenticatable < Authenticatable
      def valid?
        super && params[:controller] == "your controller" && params[:action] == "your action"
      end
    end
  end
end

let me know if it works.
