订阅身份验证数据中的密钥无效，类型：websocketError

Question

我正在使用 Laravel 5.8.*、laravel echo、pusher 和 vuejs 进行私人聊天。

尝试使用 vuejs 作为前端来监听广播事件，但在推送器的回调中没有收到数据。我可以看到发送到推送器但接收为空的私人频道和数据。当我连接到 pusher 时，我在控制台中看到以下消息：

Pusher : Event sent : {"event":"pusher:subscribe","data":{"auth":"460f6d3e4959b66a186a:3a759e55e46fc62d0188461344828ee4266edba8f1c0f5a5fd9743beb086d8cf","channel":"private-messages.1"}}

Pusher : Event recd : {"event":"pusher:error","data":{"code":null,"message":"Invalid key in subscription auth data: '460f6d3e4959b66a186a'"}}

Pusher : Error : {"type":"WebSocketError","error":{"type":"PusherError","data":{"code":null,"message":"Invalid key in subscription auth data: '460f6d3e4959b66a186a'"}}}

我尝试了所有方法，但无法找到此订阅错误的原因。我已经正确设置了所有推送数据（频道名称、密钥、秘密 ID、应用 ID、集群）。我阅读了所有其他问题，这些问题已经在 stackoverflow 中提到了相同的问题，但没有一个问题有相关的解决方案或答案。如果有人远程连接并检查我的笔记本电脑，那么再次来这里寻求帮助。

推送器仪表板的错误日志中没有错误。

Answer 1

您的客户端 JS 中的公钥与您在 .env 文件中设置的公钥不同。

我可以从客户端的屏幕截图中看到，公钥以 c07d341 开头，在您的 'env 文件中设置为：

PUSHER_APP_SECRET=160xxxxxxxx11af

最后，您收到的错误消息与公钥不匹配有关。

您是否可能在不使用命令重新编译 Javascript 依赖项的情况下更新了您的密钥

npm run dev

如果这不能解决问题，您可能还需要检查您是否没有在其他位置硬编码不正确的公钥
