Question

我在初始化程序中的refraction.rb文件

Refraction.configure do |request|
  if request.host !~ /^www./
    request.permanent! host: "www.#{request.host}" 
  end
end

我的Environment.rb文件在config

下

# Load the rails application.
Rails::Initializer.run do |config|
  config.middleware.insert_before(::Rack::Lock, ::Refraction, {})
end

require File.expand_path('../application', __FILE__)

# Initialize the rails application.

我的错误

我只是想在实际网站加载之前重定向内容。我在之前的问题上了解了折射宝石。我被卡住了。请帮帮我。

如果要这样解决，则需要先运行该应用程序，然后再运行该初始化程序。

但是在这种情况下，解决方案可能是将该行放入application.rb 而且由于时间的流逝，Rack::Lock被删除。请改用Rack::Runtime。

config.middleware.insert_before(::Rack::Runtime, ::Refraction)
