Android，Firebase登录时间稍长，WebSocketException发生

Question

我使用authWithCustomToken方法使用Firebase登录。登录大约需要5秒或更长时间。我启用了Firebase日志(setLogLevel(Logger.Level.DEBUG))来监视是否存在任何问题。Log在这里(我稍微修剪了一下，如果需要的话，我可以为它提供一个链接)：

PS: android firebase客户端版本为2.5.0

这个日志是说有错误吗？

我应该忽略它吗？如果是，为什么登录时间太长？

Answer 1

输出中没有确定任何定时影响的信息。但据我所知，水流看起来很正常。你的前两个连接被重定向了。然后，第三个连接到达正确的服务器，服务器用“建立实时连接”进行响应。

Answer 2

问题是在keepSynced(true)行之后进行身份验证。同步节点有大约250 has的数据。我认为同步数据会阻止我的身份验证。另一方面，firebase不能同步节点，因为它必须进行身份验证才能读取节点。(看起来像是死锁)我不知道实际原因是什么，但删除keepSynced(true)行解决了我目前的问题。

Firebase ref = new Firebase("my_firebase_url");
ref.child("matches").keepSynced(true); // removed this line
ref.authWithCustomToken(...);
