我正在寻找一种方法来在ExpressJS中获取客户端的时区偏移量(例如，使用req对象会很棒).

I'm searching for a way to get client's timezone offset in ExpressJS (with req object, for example, would be really great).

推荐答案

如果您控制客户端，则可以使用客户端JavaScript 进行此操作.

If you control the client, you can do this with client-side JavaScript.

如果不这样做(例如，正在构建像API这样的服务器端组件)，则无法将其从HTTP请求中拉出(除非您正在使用会话，但即使那样也不一定可靠) ).

If you don't (e.g. you're building a server-side component like an API), then you can't pull it out of the HTTP request (unless you're using sessions, but even that's not necessarily reliable).

从好的方面来说，如果仅是服务器端，您也不必担心:将所有日期对象设置为UTC或Unix时间戳，然后将其留给客户端开发人员处理时区.

On the upside, if it's only server-side, you shouldn't worry about it either: set all your date objects as UTC or a Unix timestamp and leave it to the client developer to handle timezones.
