如何在ExpressJS中结束会话
我觉得这必须埋藏在文档中的某个地方，但我找不到.
I feel like this has to be buried somewhere in the documentation, but I can't find it.
您如何关闭或结束或终止ExpressJS中的会话(无论如何)?
How do you close or end or kill (whatever) a session in ExpressJS?
Express 4.x更新的答案
会话处理不再内置于Express中.此答案涉及标准会话模块: https://github.com/expressjs/session
要清除会话数据，只需使用:
To clear the session data, simply use:
req.session.destroy();
文档对此没有多大用处.它说:
The documentation is a bit useless on this. It says:
销毁会话，删除req.session，将在下一个请求中重新生成.
req.session.destroy(function(err) { // cannot access session here })
Destroys the session, removing req.session, will be re-generated next request.
req.session.destroy(function(err) { // cannot access session here })
这不是不是，这意味着当前会话将在下一个请求时重新加载.这意味着将在下次请求时在您的会话存储中创建一个干净的空会话. (大概会话ID并没有改变，但是我还没有测试.)
This does not mean that the current session will be re-loaded on the next request. It means that a clean empty session will be created in your session store on next request. (Presumably the session ID isn't changing, but I have not tested that.)
