问题描述

我们如何使用 Node.js 的 web-push 包向多个订阅者发送通知?

How we can send a notification to multiple subscribers using web-push package of Node.js?

我们可以遍历订阅者列表，但它无法扩展到数百万订阅者.

We can loop through for list of subscribers but it won't be scalable for millions of subscribers.

示例:

for(var myKey in subData) {
    endp   =  subData[myKey]['ENDPOINT'];
    enckey =  subData[myKey]['ENCKEY'];
    webPush.sendNotification(endp, 200, enckey, JSON.stringify({
        title: 'Test Title',
        msg: 'Test Notification',
     }));
}

推荐答案

遗憾的是，Web Push 标准目前不支持向多个订阅者发送通知.

Unfortunately, the Web Push standard currently doesn't support sending a notification to multiple subscribers.

确实，密钥与特定用户有关.如果所有用户共享相同的密钥，则其他人可以读取加密的数据.阅读 [1] 以获得更详尽的解释.

Indeed, the key is related to a specific user. If all users shared the same key, the encrypted data would be readable by others. Read [1] for a more thorough explanation.

我建议实施分批发送通知的解决方案，在批次之间稍等片刻.通常通知不必是实时的，所以这通常是可行的.

I'd suggest implementing a solution that sends notifications in batches, waiting a little between the batches. Usually the notifications don't have to be real-time, so this is usually feasible.
