javascript - Firebase 通知重复消息

Question

我遇到了一个严重的问题，我收到了多个推送通知。我发现它生成了很多注册 token 。这些 token 是由同一个人制作的，使用相同的桌面，在相同的网络域中。我尝试向这些 token 发送测试消息。这些 token 有效。

有什么建议对我有帮助吗？

Answer 1

这是 Firebase 中的一个错误。我们最近修复了它，它不应该再发生了。只要 token 有效，SDK 就会一直使用同一个 token ，除非当前 token 被撤销，否则不会生成额外的 token 。

由于之前生成的 token 仍然有效，您必须从服务器中删除额外的 token (来自同一用户)。
