Question

无法从React Native连接到firebase。我可以看到它一直在重试，但从未成功。有没有人成功连接到React原生的firebase？这是在iOS 9模拟器上。

Answer 1

只是在日志中的一个想法：

 Websocket connecting to wss://<app-name>.firebaseio.com/.ws?v=5

也许您需要配置firebase应用程序名称，或者它是否显示无论如何？

Answer 2

这是由于反应原生的WebSocket polyfill的一个错误，应该在最新的位（https://github.com/facebook/react-native/commit/607527c0d4bf6d8197829f3523c4d937ac71ed07）中修复。请尝试更新并查看问题是否消失！

Answer 3

还要确保您已在Firebase数据库上启用了公开读取权限。 Firebase Db setup

Firebase永远不会从iOS上的React Native连接（模拟器）
