来自 Sinatra 基础对象。获取包括基础对象的应用程序端口
我有一个 Sinatra::Base 对象，我想将其包含在我的所有 Web 应用程序中。在该基类中，我有在启动时调用的配置方法。
我希望配置代码使用集中式数据库“注册”该服务。注册时需要发送的信息是有关如何联系此网络服务的信息……例如主机和端口。
然后，我计划建立一个监控服务，该服务将监控所有已注册的服务，并偶尔对它们进行 ping 操作，以确保它们仍然正常运行。
在配置方法中，我无法获取端口信息。 “self.settings.port”变量似乎在此方法中不起作用。
a) 关于如何获取端口有什么想法吗？我有主人。
b) 是否有一个 sinatra 插件已经可以做类似的事情，所以我不必自己编写它？ :-)
//在我的 Sinatra::Base 代码中。让我们称之为register_me.rb
注册我<西纳特拉::基地
配置执行
//保存主机和端口信息到数据库
结束
获取“/check_status”
//返回状态
结束
<小时>//在我的网络服务代码中
require register_me //此时，sinatra会初始化RegisterMe对象并调用configure
帖子（'/blah'）
//此特定 Web 服务的方法示例
结束
I have a Sinatra::Base object that I would like to include in all of my web apps. In that base class I have the configure method which is called on start-up.
I would like that configure code to 'register' that service with a centralized database. The information that needs to be sent when registering is the information on how to contact this web-service... things like host and port.
I then plan on having a monitoring service that will spin over all registered services and occasionally ping them to make sure they are still up and running.
In the configure method I am having trouble getting the port information. The 'self.settings.port' variable doesn't seem to work in this method.
a) any ideas on how to get the port? I have the host.
b) is there a sinatra plug-in that already does something like this so I don't have to write it myself? :-)
//in my Sinatra::Base code. lets call it register_me.rb
RegisterMe < Sinatra::Base
configure do
//save host and port information to database
end
get '/check_status'
//return status
end
//in my web service code
require register_me //at this point, sinatra will initialize the RegisterMe object and call configure
post ('/blah')
//example of a method for this particular web service
end

Sinatra::Application.port 将返回正确的端口
Sinatra::Application.port will return the correct port
