我想在我的非 Rails Ruby 应用程序中使用特定于环境的变量。

我尝试了不同的文件名，如.env.test.local, .env.local,.env.test

我尝试使用Dotenv.loadandrequire 'dotenv/load'方法

这就是我包装任务的方式

require 'rspec'
require 'rack/test'
require 'rspec/core/rake_task'
require 'dotenv/tasks'

task test: :dotenv do
  RSpec::Core::RakeTask.new(:spec).run_task(verbose: true)
end

这是我的服务器

require 'dotenv/load'
require 'sinatra'
require 'sinatra/reloader' if development?

set :bind, '0.0.0.0'

get ENV['API_URL'] do
  'Hello World!'
end

我的.env.test档案

API_URL=/api/v1

预期行为

API_URL 变量应该可用于:test任务运行的代码（使用bundle exec rake test）。

观察到的行为

由于ENV['API_URL']为空而导致的错误。

我想出了这个解决方法

require 'dotenv'
require 'sinatra'
require 'sinatra/reloader' if development?
Dotenv.load(".env.#{ENV['APP_ENV']}") # Remember to set your app environment

set :bind, '0.0.0.0'

get ENV['API_URL'] do
  'Hello World!'
end

它仅适用于.env.<ENVIROMENT>文件。也许这可以包装在一个函数中，但我绝对希望它由 gem 处理，就像在 Rails 应用程序中一样，这对我来说更有意义。
