如何在Rails初始化程序中获取服务器端口 [英] How to get the server port in a Rails initializer

问题描述

我有多个Rails服务器实例，并且每个实例都需要在environment.rb中知道其自己的侦听端口. request.port将在控制器中工作，但不能在environment.rb的上下文中工作.有办法吗?谢谢！

I have multiple instances of Rails servers and there is a need for each one of them to know its own listening port in environment.rb. request.port will work in the controllers but not in the context of the environment.rb. Is there a way? Thanks!

推荐答案

您可以使用以下代码获取运行中的rails端口:

You can get the running rails port using this code:

Rails::Server.new.options[:Port]

您可以查看选项Rails文档中的解析器，以查看可用的哈希参数.

You can take a look at the options parser in the Rails documentation to see what hash parameters are available.
