Rails的简单形式给出了InvalidAuthenticityToken错误 [英] Rails simple form gives InvalidAuthenticityToken error

问题描述

我有一个简单的表单，如下所示:

I have a simple form like this:

<form name="serachForm" method="post" action="/home/search">   
  <input type="text" name="searchText" size="15" value="">
  <input class="image" name="searchsubmit" value="Busca" src="/images/btn_go_search.gif" align="top" border="0" height="17" type="image" width="29">
</form>

以及使用此方法的控制器:

And a controller with this method:

  def busca
    puts params[:searchText]
  end

当我单击表单中的图像按钮时，我得到一个ActionController :: InvalidAuthenticityToken.这是完整的StackTrace:

When I do a click on the image button in the form I get a ActionController::InvalidAuthenticityToken. here's the full StackTrace:

发生了什么事?

推荐答案

默认情况下，所有非GET操作都要求将真实性令牌与请求一起传递. Rails使用真实性令牌来避免CSRF攻击.

By default, all non-GET actions requires the authenticity token to be passed along with the request. Rails uses the authenticity token to avoid CSRF attacks.

确保它始终存在的最简单方法是使用form_tag帮助器，而不是手工编写HTML.

The easiest way to ensure that it is always in place, is to use the form_tag helper instead of writing the HTML by hand.

<% form_tag "/home/search", :name => "searchForm" do %>
  fields here
<% end %>
