Question

我继承了在生产模式下运行时不能完全正常工作的Rails应用程序。对服务器的GET请求导致未找到路由匹配错误；但是，当服务器在开发模式下运行时，所有路由都可以工作，并且状态为200。

查看代码可以发现，除了成功的URL请求中使用的域之外，应用程序还希望有前缀的子域。

class ApplicationContext
 def initialize(subdomain, host_with_port)
  if subdomain.present?
  case subdomain
  when Rails.application.config.workninja.admin_subdomain
    @environment = :admin
  when Rails.application.config.workninja.mobile_subdomain
    @environment = :mobile
  else
    @environment = :customer
  end
else
  raise 'Could not initialize ApplicationContext without subdomain'
end

@url_options = {subdomain: subdomain, host: host_with_port}

setup_method = "setup_#{@environment.to_s}_environment".to_sym
 if respond_to?(setup_method, true)
  send(setup_method, subdomain, host_with_port)
 else
   raise 'Unknown context environment'
 end
end

attr_reader :environment
attr_reader :url_options
attr_reader :agency

def self.current
 Thread.current['workninja:tenant_context']
end

def admin?
 @environment == :admin
end

def mobile?
 @environment == :mobile
end

def customer?
 @environment == :customer
end

 def ui_url_for(path, subdomain = url_options[:subdomain])
   base = "#{Rails.application.config.workninja.https ? 'https' : 
  'http'}://#{subdomain}.#{Rails.application.config.workninja.domain}"
 if Rails.application.config.workninja.html5mode
   puts URI.join(base, path).to_s
 else
   puts URI.join(base, "/#/#{path}".gsub(/\/+/, '/')).to_s
 end

end

应用程序附带的原始前端根据服务器在其中启动的环境来构造请求的URL。

{
 "environment": "development",
 "url": "http://admin.workninja.local:3000"
}

{
 "environment": "production",
 "url": "/api"
}

对我来说，生产URL没有意义，因为它所做的只是将“ / api”附加到托管前端的根域中。我只能假设它只是一个占位符，一旦它在实时环境中运行，就需要替换为托管Rails服务器的域名。该应用程序的功能开发版本中并未使用“ / api”路径，这使我进一步假设它是一个占位符。

根据以上内容，我将“ / api”替换为“ http://admin.workninja.com.au”。将应用程序托管在活动域上之后，我通过运行以下命令确认它可以正常工作：

curl http://admin.workninja.com.com.au/auth -X POST

这给了我一个关于未提供凭据的预期错误，但它表明服务器实际上正在接收某些信息。如果您尚未意识到在生产模式下启动时的rails服务器会响应POST请求，但不会响应GET。

这是我对问题的理解破裂的地方。如果

http://admin.workninja.local:3000/roles

在开发环境中工作正常（“ /角色是应用程序路线之一”）

http://admin.workninja.com.au/roles

在生产环境中也可以工作吗？您是否可以从这个事实中推断出ruby代码库中没有损坏某些东西？

以下是与生产环境中的rails应用程序的配置有关的一些文件。

/config/deploy/production.rb

  config.active_record.dump_schema_after_migration = false

  # Application hostname
  config.surgeforce.domain = 'surgeforce.com.au'
  config.surgeforce.https = false
  config.surgeforce.html5mode = true

end

/config/puma.rb

  ActiveRecord::Base.connection.disconnect! rescue ActiveRecord::ConnectionNotEstablished
  ActiveRecord::Base.establish_connection(ENV["DATABASE_URL"] || YAML.load_file("#{cwd}/config/database.yml")[ENV["RAILS_ENV"]])
end

如果您认为应用程序中的任何其他代码对调查至关重要，请告诉我，我将其包括在内。

问题在于，Rails的subdomain方法非常简单，对com.au域的结构一无所知。对于您在生产中使用的"admin.workninja.com.au"，subdomain方法将返回"admin.workninja"。从文档中：

将所有\ subdomains返回为一个字符串，因此"dev.www"将是返回"dev.www.rubyonrails.org"。您可以在“ www.rubyonrails.co.uk”中指定其他tld_length，例如2以捕获"www"而不是"www.rubyonrails"。

而且–在不知道您的配置– "admin.workninja"的情况下，很可能不再与您的config.workninja.admin_subdomain配置匹配。

解决方案是在生产中使用configure a tld length of 2。只需将以下内容添加到config/environments/production.rb中的配置块中即可：

config.action_dispatch.tld_length = 2 # Defaults to 1

Rails应用程序GET路线在生产模式下不起作用
