随着新的更新,现在将使用 FCM。
我尝试了 git 中的示例应用程序,它运行良好。我可以从控制台发送通知。
但是我想在触发某个事件后从服务器发送通知。我采用了与 GCM 中相同的方法,但它不起作用。

我正在按照这个PHP 脚本发送通知。如果我尝试执行脚本,我会得到以下结果。
{"multicast_id":4679427854122301046,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1463757518309261%31bd1c96f9fd7ecd"}]}
注意:我浏览了他们的文档并修改了代码要点,使其只有正文和标题。即使那样它也不起作用。
