Question

在生产网站中，我有一个使用路线start#index定义的主页。

这可以按预期工作。

现在，一些抓取工具正在扫描页面中的/crossdomain.xml之类的内容，这会触发start控制器运行，并尝试返回XML视图。

不幸的是我没有定义XML视图或模板或其他任何内容，因此会生成错误消息（通过电子邮件，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

所以我猜有两种选择：

在此应用中禁用所有XML / JSON并呈现默认的404页面。
创建一个虚拟XML视图。

我更喜欢第一种选择，但我不确定如何做到这一点？感谢您的建议或最佳实践的链接。

编辑，根据要求，输出rake routes。我猜到第二行最后一行会出现一些错误？

Answer 1

您可以使用路线约束，以便只接受html作为格式。这将为您提供首选。

查看this和this。

Answer 2

控制器操作的响应块包含哪些内容？如果您已离开默认区块：

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

但尚未定义XML模板，您将收到错误消息。删除format.xml（或者如果你只想要HTML，你可以完全省去respond_to块），除了HTML之外的任何格式请求都将失败。

禁用所有XML视图
