ActionController::InvalidAuthenticityToken解决办法

第一种：
Ror代码

  class FooController < ApplicationController 
        protect_from_forgery :except => :index 
     
      # you can disable csrf protection on controller-by-controller basis: 
       skip_before_filter :verify_authenticity_token 
  end 

class FooController < ApplicationController     protect_from_forgery :except => :index      # you can disable csrf protection on controller-by-controller basis:     skip_before_filter :verify_authenticity_token   end



第二种：
修改配置文件config\environments\development.rb

Ror代码

    # Disable request forgery protection in development environment 
       config.action_controller.allow_forgery_protection = false 

# Disable request forgery protection in development environment    config.action_controller.allow_forgery_protection = false


然后重启服务器

第三种：
在jquery或form中加入
Ruby代码

   <%= tag(:input, :type => "hidden", :name =>  
   request_forgery_protection_token.to_s, :value =>  
   form_authenticity_token) %>
