Question

我在Rails中开发了一个API，我想通过api.domain.com访问它。在本地，我修改了/etc/hosts文件，因此domain.com和api.domain.com都解析为localhost。对于暂存和制作，我为api.domain.com和api.staging.domain.com创建了CNAME别名，以指向各自的服务器domain.com和staging.domain.com。

在我的routes.rb中，我所有的api路径都嵌套在

中

namespace :api, path: '/', defaults: { format: 'json' }, constraints: { subdomain: 'api' } do

当我向api.domain.com发出请求时，本地工作正常。但是当我尝试对生产和登台服务器执行相同操作时，我的请求失败，说它无法匹配路由，例如：

这个怎么样？

# inline
constraints: { subdomain: /api(?:\.(staging))?/ }


# config/routes.rb

# API Routes
constraints subdomain: /api(?:\.(staging))?/ do
  ...
end

以上内容符合：api.example.com，api.staging.example.com

您也可以轻松地将其他人添加到此，例如

# config/routes.rb

# API Routes
constraints subdomain: /api(?:\.(staging|other))?/ do
  ...
end

上述内容符合：api.example.com，api.staging.example.com，api.other.example.com

生产和暂存api子域无法正常工作
