你如何将 iframe 放入降价脚本中?
我有一个客户端应用程序,使用REST服务与服务器通信.客户端应用程序是多语言的,这意味着服务器必须在呼叫期间知道用户的语言环境.我想使用"post for location"方法,因为它有一种美好而宁静的感觉.当数据被发布以说出动作资源时,那么uri是:
/actions/{language}
Run Code Online (Sandbox Code Playgroud)
该语言非常重要,因此我可以为GET本地化错误消息(有时是返回的数据).现在,当服务器响应时,它需要发回资源的URI.如果我寄回去
/actions/{id}
Run Code Online (Sandbox Code Playgroud)
其中id是新创建的资源的id,这不完全正确
/actions/{language}/{id}
Run Code Online (Sandbox Code Playgroud)
将是本地化资源的URI.但是,实际资源没有语言上下文.
对这种情况的最佳实践有何看法?

我没有受过教育的猜测是,无法看到Customer类.但是单元测试和数据访问层都引用了包含Customer类的DataTransfer程序集.Customer类是公共的,所有属性都是公共虚拟的.
