传入 Apple 推送通知的端口号 [英] Port Number for Incoming Apple Push Notifications

问题描述

需要在网络上打开哪些网络服务、端口号、传出传入或两者兼而有之，ipod touch 才能接收 Apple 推送通知?

What network services, port numbers, outgoing incoming or both, need to be open on a network for an ipod touch to receive Apple Push Notifications?

我知道发送 apns 时要设置的传出端口号.唯一的问题是，在我的学校，几乎每个传出(和传入)端口都被阻止，因此 APN 无法正常工作.我确信，如果我与我的网络管理员交谈并告诉他要取消阻止哪个端口，他就会这样做.所以我的问题是:需要在网络上打开哪些网络服务、端口号、传出传入或两者兼而有之，ipod touch 才能接收 Apple 推送通知?

I know the outgoing port number to set when sending the apns. The only thing is, in my school practically every outgoing (and incoming) port is blocked and as a result APNs do not work. I am sure that if I talked to my network administrator and told him which port to unblock, he would do so. So my question is: What network services, port numbers, outgoing incoming or both, need to be open on a network for an ipod touch to receive Apple Push Notifications?

推荐答案

根据 Apple 的文档: 端口 5223.

According to Apple's docs: port 5223.

如果设备通过 Wi-Fi 连接并且仍然无法接收通知，Wi-Fi 网络您使用的可能有防火墙阻塞端口 5223.这个端口必须对 TCP 流量开放通知工作.

If the device is connected over Wi-Fi and is still unable to receive notifications, the Wi-Fi network you're using might have a firewall that is blocking port 5223. This port must be open to TCP traffic for notifications to work.
