Rails渲染content_type不起作用？

Question

我的代码很简单：

  def xrds
       @services = {
                '0' => {
                        'Type' => [OpenID::OPENID_2_0_TYPE,OpenID::OPENID_1_0_TYPE],
                        'URI' => root_url
                        }
                }
        render :content_type => 'application/xrds+xml'
  end

但是Rails返回的内容类型是text / xml。任何想法如何解决这一问题？我的rails版本是3.0.6

Answer 1

尝试使用（渲染前）：

response.headers['content-type'] = 'application/xrds+xml'
