Question

请考虑此测试：

def test_ok_on_second_request
  bad_response = @request.get "/bad-response"
  assert_equal 404, bad_response.status

  good_response = @request.get "/test-title"
  assert_equal 200, good_response.status
  assert_equal "text/html", good_response.content_type
end

我确信/test-title是一条有效的道路。应该返回200的断言实际上是返回404。 Rack如何为同一请求返回两个不同的结果？

这是项目中Server类的代码：

module Blogrite
  class Server
    attr_accessor :status, :mimetype, :body, :provider
    def initialize *args, &block
      @status, @mimetype = 200, "text/html"
      provider = args[0][:with].nil? ? :filesystem : args[0][:with]
      @provider = Blogrite.const_get(provider.capitalize).new
      # p "Server is running with #{@provider.class}."
    end

    def call env
      begin
        article   = go env['PATH_INFO'].delete("/")
      rescue Blogrite::Article::NoBodyError
        @status = 404
      end

      @status   = 404 if !article
      @status   = 403 if env["REQUEST_METHOD"] == 'POST'
      @mimetype = "text/css" if env["PATH_INFO"].include?("css")
      @body     = if article then article.render
                  elsif env.respond_to?(:to_yaml) then "<pre>#{env.to_yaml}</pre>"
                  else "oops"
                  end

      [@status,{ "Content-Type" => @mimetype},[@body]]
    end

    def go path
      f = @provider.fetch path
      Article.parse f unless f.nil?
    end
  end
end

整个工作流程太大，我无法将其粘贴，但您可以在Github上查看项目。感谢您的帮助，谢谢。

问题的解决方案就像在@status函数中初始化call一样简单。

    class Server
      attr_accessor :status, :mimetype, :body, :provider
      def initialize *args, &block
 -      @status, @mimetype = 200, "text/html"
        provider = args[0][:with].nil? ? :filesystem : args[0][:with]
        @provider = Blogrite.const_get(provider.capitalize).new
        # p "Server is running with #{@provider.class}."
      end

      def call env
        begin
 -        article   = go env['PATH_INFO'].delete("/")
 +        @status, @mimetype = 200, "text/html"
 +        article = go env['PATH_INFO'].delete("/")
        rescue Blogrite::Article::NoBodyError
          @status = 404
        end

这样，机架实例 - 只被调用一次 - 不在请求的范围之内。每个调用函数都应该有自己的默认值，而不是服务器类。
