禁用所有XML视图

Question

在生产站点中，我有一个使用路由start#index定义的主页。

这如预期的那样起作用。

现在，一些爬虫正在扫描页面中的内容，比如/crossdomain.xml，这将触发start控制器运行，并试图返回start视图。

不幸的是，我没有定义XML视图或模板或有关它的任何内容，因此生成了错误消息(通过eMail，因此非常烦人)：

[Exception] start#index (ActionView::MissingTemplate) "Missing template
start/index with {:handlers=>[:rjs, :rhtml, :builder, :rxml, :erb],
:formats=>[:xml], :locale=>[:crossdomain, :en]} in view paths

所以我想有两个选择：

• 禁用此应用程序中的所有XML/JSON，并呈现默认404页。
• 创建一个虚拟XML视图。

我更喜欢第一选择，但我不知道该怎么做？谢谢你的建议或链接到一个最佳实践。

按要求编辑，rake routes的输出。我想我在最后一行看到了一些错误吧？

Answer 1

您可以使用路由约束，以便只接受html作为格式。这将给你第一选择。

看看这和这。

Answer 2

控制器操作的响应块包含哪些内容？如果您已经离开了默认块：

respond_to do |format|
  format.html { redirect_to(foobar_url) }
  format.xml  { head :ok }
end

但是还没有定义XML模板，您将得到一个错误。删除format.xml (或者如果您只需要respond_to，您可以完全放弃respond_to块)，任何对HTML之外的格式的请求都会失败。
