setInterval 重置后保持旧间隔
setInterval keeping old interval after reset
我的应用每 5 小时轮询一次体育赛事。如果没有发现体育赛事，则此间隔将减少到 1 小时。我省略了文件中不相关的部分，因为它是一个巨大的文件并且与此间隔无关。您可以看到，最初如果 NODE_ENV 是生产，调用 pollEvents 的间隔是 5 小时。如果没有有效事件，setNoEventsInterval 被称为 （你可以在下面的日志中看到），这应该重置间隔 (eventPollInterval) 到 1 小时。如果在该间隔之后发现事件，则间隔重置为 5 小时。

从日志中可以看出，当setNoEventsInterval最初被调用时@[2020-03-2402:00:44]，这将重置interval as EVENT_POLL_RESET 是错误的。但是，pollEvents 直到 [2020-03-24 07:00:44] 才被调用，也就是最初调用该函数的 5 小时后间隔是。
当没有更多有效事件时，将再次调用 setNoEventsInterval @ [2020-03-24 09:30:09] 它将重置再次间隔，但这次它起作用了，你可以看到 pollEvents 然后被称为 @ [2020-03-24 10:30:09].
为什么第一次时间隔似乎没有正常清除，但第二次却绕开了？我也对为什么 remainingMinutes 变量重置时间感到困惑，因为我不重置它的间隔。 [2020-03-24 07:55:44] & [2020-03-24 08:00:44]之间，剩余时间从 4 分钟回到 59 分钟，但据我所知，我根本没有重置 timeSet 变量
编辑
剩余的分钟数无关紧要，我认为它只是按小时滚动，我从小时开始得到分钟数。仍然对为什么不修改间隔感到困惑。
编辑 2
当间隔最初在 1 小时后解决时，我输入了更多日志记录，所以我希望记录 ----- NEW POLL (1 HOUR) ----- 但它永远不会
最后我在调试的时候弄明白了。问题出在即时函数调用中，我正在等待对 pollForEvents 的调用。如果此 returns 没有事件，或者由于某些其他原因调用 setNoEventsInterval，则间隔设置为一小时。但是，当 pollForEvents 最终解决时，如果 NODE_ENV 是 "production" 的条件再次将其设置为 5 小时。这就是为什么我只看到这种情况发生在最初的民意调查中，而不是随后的民意调查中。我刚刚添加了一个条件，如果 eventPollInterval 存在，请不要重置它。
我的应用每 5 小时轮询一次体育赛事。如果没有发现体育赛事，则此间隔将减少到 1 小时。我省略了文件中不相关的部分，因为它是一个巨大的文件并且与此间隔无关。您可以看到，最初如果 NODE_ENV 是生产，调用 pollEvents 的间隔是 5 小时。如果没有有效事件，setNoEventsInterval 被称为 （你可以在下面的日志中看到），这应该重置间隔 (eventPollInterval) 到 1 小时。如果在该间隔之后发现事件，则间隔重置为 5 小时。

从日志中可以看出，当setNoEventsInterval最初被调用时@[2020-03-2402:00:44]，这将重置interval as EVENT_POLL_RESET 是错误的。但是，pollEvents 直到 [2020-03-24 07:00:44] 才被调用，也就是最初调用该函数的 5 小时后间隔是。
当没有更多有效事件时，将再次调用 setNoEventsInterval @ [2020-03-24 09:30:09] 它将重置再次间隔，但这次它起作用了，你可以看到 pollEvents 然后被称为 @ [2020-03-24 10:30:09].
为什么第一次时间隔似乎没有正常清除，但第二次却绕开了？我也对为什么 remainingMinutes 变量重置时间感到困惑，因为我不重置它的间隔。 [2020-03-24 07:55:44] & [2020-03-24 08:00:44]之间，剩余时间从 4 分钟回到 59 分钟，但据我所知，我根本没有重置 timeSet 变量

剩余的分钟数无关紧要，我认为它只是按小时滚动，我从小时开始得到分钟数。仍然对为什么不修改间隔感到困惑。

当间隔最初在 1 小时后解决时，我输入了更多日志记录，所以我希望记录 ----- NEW POLL (1 HOUR) ----- 但它永远不会
最后我在调试的时候弄明白了。问题出在即时函数调用中，我正在等待对 pollForEvents 的调用。如果此 returns 没有事件，或者由于某些其他原因调用 setNoEventsInterval，则间隔设置为一小时。但是，当 pollForEvents 最终解决时，如果 NODE_ENV 是 "production" 的条件再次将其设置为 5 小时。这就是为什么我只看到这种情况发生在最初的民意调查中，而不是随后的民意调查中。我刚刚添加了一个条件，如果 eventPollInterval 存在，请不要重置它。
