推荐答案

当浏览器关闭时，没有消息发送到服务器，因此没有要监听的抢占事件.您要做的是使变量可用于您的线程，该变量指示用户上次从服务器请求资源的时间.自从用户上次请求过期以来经过了一定的时间后，您就结束了线程.然后，在您的HTML中添加一个javascript ajax请求，该请求ping您的服务器以使线程保持活动状态.

There is no message sent to the server when the browser closes so there's no preemptive event to listen to. What you'll want to do is make a variable available to your threads that indicates when the user last requested a resource from your server. Once a certain amount of time has passed since the user last requested expires you end the threads. Then, in your HTML add a javascript ajax request that pings your server to keep the threads alive.

显然，您需要调整超时时间，以平衡用户的性能和可靠性.

Obviously you'll need to tweak the timeouts to balance performance and reliability for your users.
