运行Sinatra应用程序的首选方法是什么？

编辑：我让应用程序使用TorqueBox，所以我猜这个问题与特立尼达有关。但是，我认为我对运行Sinatra应用程序的首选方式的猜测仍然有效。

我使用的是JRuby，Bundler和模块化风格。这是我的应用程序代码：

# myapp.rb
class MyApp < Sinatra::Base
  configure :development do
    register Sinatra::Reloader
  end

  set :server, 'trinidad'
  set :environment, :development
  set :logging, true
  #...
end

# config.ru
require 'bundler/setup'

Bundler.require(:default)

$: << File.dirname(__FILE__)

require 'myapp'

run MyApp

# Gemfile
source 'http://rubygems.org'

gem 'rack'
gem 'sinatra', :require => 'sinatra/base'
gem 'sinatra-contrib', :require => 'sinatra/reloader'
gem 'coffee-script'
gem 'neography'
gem 'gon-sinatra'
gem 'sass'
gem 'trinidad'

启动我的应用程序的正确方法（即什么样的命令）是什么？我正在使用Trinidad，因为我读到它是JRuby应用程序的好解决方案（我无法让TorqueBox工作）。目前我正在通过'trinidad config.ru'运行我的应用程序，但它会抛出以下类似的错误消息：

我正在使用Trinidad和Rack的1.4.1版本，JRuby的1.7.0.preview1和Sinatra的1.3.3。

如果我运行'bundle exec trinidad config.ru'，我会收到以下错误：

默认情况下不加载rubygems（至少使用jruby --1.8）因此你可以在 config.ru 之上添加require 'rubygems'作为JRuby（实际上是JRuby-Rack） ）默认情况下，将您的应用程序加载到单独的“运行时”（一种新的ruby进程，但在同一JVM进程中）。 或者，您也可以使用rackup -s trinidad

运行

答案 1 :(得分：0)

就调用机架配置和应用程序的CLI命令而言，kares是正确的。如果你没有使用Torquebox，那么使用带有“-s trinidad”的“rackup”就可以了。

至于从机架配置中调用应用程序的Ruby命令，这就是我所做的..不确定这是否适用于您的情况，如果这是您正在寻找的，但无论如何都会有所帮助HTTP处理程序：

你有MyApp，它混合在Sinatra :: Base中。如果你修改该类只配置你的环境，并为每个页面加载运行“before do”和“after do”...但实际上并不处理和获取/发布调用;然后，您可以创建专门的类来处理整个应用程序中的某些路径。这使用Rack :: Builder的map（）方法...... 

require 'myapp'
require 'mylanding'
require 'myauthentication'
require 'myautocomplete'
require 'mysearch'

#de run MyApp

map "/" do
    run MyLanding    #de Catch-all, which would have "get '/*' do" in it too.
end

map "/authentication/" do
    run MyAuthentication
end

map "/autocomplete/" do
    run MyAutocomplete
end

map "/search/" do
    run MySearch
end

然后在每个My *类中，执行以下操作：

class MyLanding < MyApp
  get "/*" do
    ..handle landing.. or see what's in the splat.
  end
end

class MyAuthentication < MyApp
  get "/sign/in" do
    ..present sign-in..
  end
  post "/sign/in" do
    ..handle sign-in..
  end
end

等...

您的子类对每个页面加载都有整体MyApp处理，但添加路由，例如/ authentication / sign / in由MyAuthentication的/ sign / in处理。这是一个很酷的方式，使用相同的基础：MyApp。
