ruby-on-rails - Rails 应用程序 GET 路线在生产模式下不起作用
问题描述
我继承了一个在生产模式下运行时功能不完全的 Rails 应用程序。对服务器的 GET 请求导致找不到路由匹配错误;但是,当服务器以开发模式运行时,所有路由都将起作用,并给出预期的 200 状态。
查看代码可以发现,除了成功的 URL 请求中使用的域之外,应用程序还需要一个带前缀的子域。
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
应用程序提供的原始前端根据服务器启动的环境构建请求的 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”附加到前端托管的根域。我只能假设它只是一个占位符,一旦它在实时环境中运行,就需要用 Rails 服务器托管的域名替换。“/api”路径并未在应用程序的整个功能开发版本中使用,这让我进一步假设它是一个占位符。
使用上述内容作为指导,我将“/api”替换为“ http://admin.workninja.com.au ”。在活动域上托管应用程序后,我通过运行确认它正在工作:
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一些东西。如果您还没有意识到 Rails 服务器在生产模式下启动时会响应 POST 请求,但仍然不会响应 GET。
这就是我对问题的理解崩溃的地方。如果
http://admin.workninja.local:3000/roles
在开发环境中工作(“/角色是应用程序路由之一”)为什么不
http://admin.workninja.com.au/roles
也可以在生产环境中工作?你能从这个事实中假设 ruby 代码库中没有损坏吗?
下面是一些与在生产环境中配置 rails 应用程序相关的文件。
/config/deploy/production.rb

Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.

config.cache_classes = true
# Eager load code on boot. This eager loads most of Rails and

config.action_controller.perform_caching = true
# Enable Rack::Cache to put a simple HTTP cache in front of your application
# Add `rack-cache` to your Gemfile before enabling this.
# For large-scale production use, consider using a caching reverse proxy like

config.surgeforce.domain = 'surgeforce.com.au'
config.surgeforce.https = false
config.surgeforce.html5mode = true
end
/config/puma.rb
threads 1, 6
workers Integer(ENV['PUMA_WORKERS'] || 3)
on_worker_boot do
require "active_record"

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代码的任何其他部分对调查至关重要,请告诉我,我会将其包括在内。
解决方案
问题是 Rails 的方法非常简单,对域subdomain
的结构一无所知。com.au
您"admin.workninja.com.au"
在生产中使用的subdomain
方法将返回"admin.workninja"
. 从文档:
将所有 \subdomains 作为字符串返回,因此
"dev.www"
将返回"dev.www.rubyonrails.org"
. 您可以指定一个不同的tld_length
,例如 2 来"www"
代替"www.rubyonrails"
“www.rubyonrails.co.uk”。
而且 - 在不知道您的配置的情况下– "admin.workninja"
很可能不再匹配您的config.workninja.admin_subdomain
配置。
解决方案是在生产环境中配置 tld 长度为 2。只需将以下内容添加到您的配置块中config/environments/production.rb
:
config.action_dispatch.tld_length = 2 # Defaults to 1
