在ExpressJS中获取客户的时区偏移量 [英] Get client's timezone offset in ExpressJS

问题描述

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

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.
