Rails 6默认绑定到127.0.0.1

Question

我观看了一场关于不安全rails默认值的安全对话(尽管很老(。我想知道是否有一种方法可以判断Rails现在是否绑定到ip 127.0.0.1，默认情况下是3000端口？当我旋转轨道时，我看到

±  |master {1} U:4 ✗| → rails s

根据这篇相当古老的Stack溢出文章，我尝试将以下内容添加到我的boot.rb中，但在我的Spring版本中出现了一个错误。

Boot.rb需要"轨道/命令/服务器">

module Rails
class Server
def default_options
super.merge({Port: 10524, Host: '127.0.0.1'})
end
end
end

±  |master {1} U:4 ✗| → rails s
You've tried to invoke Spring when it's already loaded (i.e. the Spring constant is defined).
This is probably because you generated binstubs with Spring 1.0, and you now have a Spring version > 1.0 on your system. To solve this, upgrade your bundle to the latest Spring version and then run `bundle exec spring binstub --all` to regenerate your binstubs. This is a one-time step necessary to upgrade from 1.0 to 1.1.

我做了这些步骤，但仍然是一个错误。

您使用的是Rails 6，最新版本使用的是puma，您的应用程序也是如此。如果要更改端口，请打开config/puma.rb。在那里你会看到

port        ENV.fetch("PORT") { 3000 }

这条线路使铁路从3000港开始。将其更改为任何其他端口。在您的情况下-

port        ENV.fetch("PORT") { 10524 }

此外，如果您想更改绑定地址，请将port替换为bind

#port        ENV.fetch("PORT") { 3000 }
bind        'tcp://192.168.0.1:10524'
