Express Node.js应用程序中的全局服务器会话

Question

How should I gave access to the current session to the modules of my node.js app considering that I can only get it inside the request's function?
It's a fairly complex but modular app and passing the session around seems a bit difficult, and I would have to reimplement a lot of things.
Ideally i would attach it to an object exported with module.exports and require it in other modules. But I'm afraid that on concurrent requests it would get overwritten and I could end up with conflicts.

Answer 1

Have you tried res.locals ? In the Official Docs, it says "Response local variables are scoped to the request, thus only available to the view(s) rendered during that request / response cycle, if any. This object is useful for exposing request-level information such as the request pathname, authenticated user, user settings etcetera. "

When your middleware/route callback is called, you can define res.locals.myProp = "some value" and access it from a view, using locals.myProp .

我通过使用express-domain-middleware解决了这一问题，该软件将来自express的传入请求和响应绑定到新域 。
