Question

我有一个这样的简单形式：

<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>

使用此方法的控制器：

  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：

发生了什么事？

Answer 1

沿着Nat的路线，添加

<%= token_tag %>

在HTML“form”标签工作之后

Answer 2

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。

确保它始终存在的最简单方法是使用form_tag帮助程序而不是手动编写HTML。

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

Answer 3

如果您不使用帮助程序生成表单标记，则可以使用真实性标记手动生成隐藏字段：

<input type="hidden" 
       value="<%= form_authenticity_token() %>" 
       name="authenticity_token"/>

Answer 4

使用其他人建议的表单助手可以正常工作。

由于这是一个搜索表单，该方法实际上应该是'get'。通常，除非数据库中的某些内容发生变化，否则应使用“get”。

对搜索表单使用method ='get'也更加友好的书签/后退按钮。
