什么速率的推送通知会触发 TooManyRequests 错误?

What Rate of Push Notifications Triggers TooManyRequests Error?

很简单...

比如我循环发送5个,这样会触发失败吗?

只是想知道是否有经验的人可以大概理解这一点。

文档中没有具体限制(Communicating with APNs)。

There are no caps or batch size limits for using APNs. The iOS 6.1 press release stated that APNs has sent over 4 trillion push notifications since it was established. It was announced at WWDC 2012 that APNs is sending 7 billion notifications daily.

If you're seeing throughput lower than 9,000 notifications per second, your server might benefit from improved error handling logic.

错误 429 表示 The server received too many requests for the same device token。如果您遇到问题,您可能需要检查 Technical Note TN2265 - Troubleshooting Push Notifications
