我有一个奇怪的问题。我正在尝试让 Apple Push Notifications 与 Python 一起使用。我可以毫无问题地连接和发送个人消息。当我开始发送多条消息时,问题就会出现,但它甚至比这更奇怪。
我正在使用多种设备进行测试……一些 iPhone 和一些 iPod Touch。我可以毫不费力地向 iPhone 发送多条消息,但如果列表中有 iPod Touch 设备 ID,则后面的任何消息都会失败。
因此,如果我像这样按顺序发送 4 条消息:
1 - iPhone
2 - iPhone
3 - ipod Touch
4 - iPhone
1 和 2 将交付, 3 和 4 失败。
使用相同的设备 ID,如果我将任何 iPod Touch 设备 ID 作为第一条消息,所有消息都会失败。同样,如果我只发送到 iPhone,所有消息都会成功。
这是我正在测试的代码,在当前状态下,我只会收到前两条消息,后两条每次都会失败。
