Sinatra使用瘦web服务器，如何让它显示get＆＃34; request-url＆＃34;

Question

在默认的sinatra webserver webrick中，在开发模式下，我可以在stdout中得到以下内容：

127.0.0.1 - - [23/May/2017:19:23:10 CST] "GET / HTTP/1.1" 200 4
- -> /

但是当我

set :server, "thin"

没有显示请求信息，如何打开它？我希望显示精简登录代码，而不是thin --debug cli

更新

这里是完整代码：

require 'sinatra/base'

class App < Sinatra::Base
  set :server, "thin"

  get '/' do
    "hello world"
  end

  get "/hello" do
    "drlow elloh"
  end
end

App.run!

Answer 1

如果您没有更改任何配置，则与瘦无关。请添加主应用程序文件，sinatra，瘦和机架版本。

示例

2分钟的集会

$ mkdir thiny
$ nano thiny/app.rb
$ cd thiny/
$ ruby app.rb 

以下行是打印到std输出的日志，我相信你正在寻找。

== Sinatra (v2.0.0) has taken the stage on 4567 for development with backup from Thin

127.0.0.1 - - [23/May/2017:16:04:19 +0400] "GET /hello HTTP/1.1" 200 11 0.0007

app.rb的内容

require 'sinatra'

set :server, "thin"

get '/' do
  "hello world"
end

get "/hello" do
  "drlow elloh"
end

Answer 2

我找到了解决方案，只需添加set :logging, true，这里是正确的代码：

require 'sinatra/base'

class App < Sinatra::Base
  set :server, "thin"
  set :logging, true

  get '/' do
    "hello world"
  end

  get "/hello" do
    "drlow elloh"
  end
end

App.run!
