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  

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) %>
