iOS有效负载，但没有要传送的内容(缺少device_tokens、标记、段或别名)

Question

我正在为我的应用程序进行后台下载，但我正在

iOS payload, but nothing to deliver to (missing device_tokens, tags, segments, or aliases) 

当我在终端中插入以下内容时：

curl -v -X POST -u "<appKey>:<master key>" -H "Content-type: application/json" -H "Accept:
application/vnd.urbanairship+json; version=3;" --data '{"audience":"all", "device_types" : ["ios"],    "notification": {"ios": {"content-available":true, "sound": "default", "badge": 1, "message": "Hi there!", "priority":5}}}' https://go.urbanairship.com/api/push/

我想知道curl代码中是否有任何格式错误。

终端返回：

Answer 1

首先，你不应该张贴你的证书让所有人看到。这可以让任何人向你的应用程序用户发送通知！

其次，问题似乎是，在您的"ios“部分中，您需要通过设备令牌、标签、细分市场或别名来指定您的受众。这些是UA提供给您的机制，用于确定哪些用户应该接收通知。
