ruby-on-rails - Rails ActionView::MissingTemplate 用于不应该存在的模板

Question

在从根路径上的某些 IP 地址进行生产时，我随机收到此错误。 rails 应用程序不支持格式 :formats=>[:gif, "image/x-xbitmap", :jpeg, "image/pjpeg", "application/x-shockwave-flash", "application/vnd.ms-excel", "application/vnd.ms-powerpoint", "application/msword"]因此，如果为他们提出请求，似乎会出现此错误。我猜有人或某个机器人正试图对该站点运行漏洞利用——我如何将这些类型的请求重定向或路由回路由路径，以便不会产生错误？

ActionView::MissingTemplate: Missing template front_page/index, application/index with {:locale=>[:en], :formats=>[:gif, "image/x-xbitmap", :jpeg, "image/pjpeg", "application/x-shockwave-flash", "application/vnd.ms-excel", "application/vnd.ms-powerpoint", "application/msword"], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :arb, :jbuilder]}.

要在您的评论中获得所需的结果:

constraints :format => "html" do
  resources ...
end

或者，如果您需要更多的灵活性:

# application_controller.rb
ApplicationController < ActionController::Base
  before_action :check_format!
  ...
  def check_format!
    unless request.format == :html
      render :nothing status: :bad_request
    end
  end
  ...
end

但总的来说，我觉得这一切都太过分了......

另外，看到 respond_to 的桶是非常典型的。在 Controller 中，因为正常行为是尝试提供任何格式。否则，可能会有大量的配置等。

Is there a way to do this for all controller actions unless explicitly stated

所以当你说 unless explicitly stated你有点逆流而上。
