<pre><code>req.session.destroy();

The above did not work for me so I did this. 

<pre><code>req.session.cookie.expires = new Date().getTime();
</code></pre>

By setting the expiration of the cookie to the current time, the session expired on its own.

You can retrieve the id of a session using <code>req.session.id</code> or <code>req.sessionID</code> and then pass it to <code>req.sessionStore.destroy</code> method like so:
<pre><code>const sessionID = req.session.id;
req.sessionStore.destroy(sessionID, (err) =&gt; {
 // callback function. If an error occurs, it will be accessible here.
 if(err){
 return console.error(err)
 }
 console.log(&quot;The session has been destroyed!&quot;)
})
</code></pre>

I feel like this has to be buried somewhere in the documentation, but I can't find it. 

How do you close or end or kill (whatever) a session in ExpressJS?

How to end a session in ExpressJS

我觉得这必须隐藏在文档中的某个地方，但我找不到它。如何在ExpressJS中关闭、结束或终止(任何)会话？
