我在我的开发日志中没有看到未经授权的连接尝试被拒绝错误，所以我想这一定是问题所在。但谷歌搜索这个短语并没有帮助
如何缩小问题范围？
在我看来，ActionCable部分正在工作，但存在身份验证错误成功升级到WebSocket
表示它打开了与用户的WebSocket连接，但拒绝了未经授权的连接尝试
表示您在代码中的某个位置拒绝了他们的连接
检查你的connection.rb
文件，你是否在某处调用reject\u unauthorized\u connection

可能的解决办法

我添加了connection.rb的connect。我从一本指南上抄的。你一定是对的。当我将find\u verified\u user
方法的内容替换为user.find（5）
时，我就可以为该用户使用ActionCable了。你真是我的救命稻草！非常感谢你。我在你的答案中添加了修复程序。出于某种原因，我有类似的配置，nginx返回301
