我正在为 Docker (laradock) 上的 Laravel echo 服务器设置而苦苦挣扎。我跟进了本教程。我在 docker 下设置了一个新的 laravel 项目,并将主机设置为 testing.localhost。与 Redis 的连接工作正常,回显服务器工作正常,甚至可以监听消息:

    L A R A V E L  E C H O  S E R V E R

version 1.6.2

⚠ Starting server in DEV mode...

✔  Running at localhost on port 6001
✔  Channels are ready.
✔  Listening for http events...
✔  Listening for redis events...

Server ready!

Channel: user-channel
Event: UserEvent

我的 laravel-echo-server.json 包含以下内容:

{
    "authHost": "localhost",
    "authEndpoint": "/broadcasting/auth",
    "clients": [],
    "database": "redis",
    "databaseConfig": {
        "redis": {
            "port": "6379",
            "host": "redis"
        }
    },
    "devMode": true,
    "host": null,
    "port": "6001",
    "protocol": "http",
    "socketio": {},
    "sslCertPath": "",
    "sslKeyPath": ""
}

在客户端应用程序(Angular 应用程序)上,我尝试了几种组合:

// const config: SocketIoConfig = { url: '10.0.75.1:6001', options: {} }; - docker IP address
// const config: SocketIoConfig = { url: '192.168.1.7:6001', options: {} }; - my IP address
// const config: SocketIoConfig = { url: 'localhost:6001', options: {} };
// const config: SocketIoConfig = { url: '127.0.0.1:6001', options: {} };

但我总是在控制台中收到一条消息

/socket.io/?EIO=4&transport=polling&t=Nf9A_rY net::ERR_CONNECTION_REFUSED

有谁知道如何解决这个问题?
