node.js - Azure 中托管的节点服务器上的 Websocket 失败

Question

我有一个准系统的简单示例，可以在本地工作，但不能在 Azure 中工作。我最初的问题有点特定于一个 cors-error，我现在已经解决了这个问题，因此编辑掉了那部分。但我仍然无法让 WS 在 azure 上工作。我需要帮助。

var server = http.Server(app);
const wss = new WebSocket.Server({server});

server.listen(8070, () => {
  console.log("Listening on " + port)
});


wss.on('connection', (socket) => {
  console.log('a user connected');
  socket.on('message', (msg) => {
    console.log(msg)
    socket.send(JSON.stringify({hey:'you'}))
  })
});

客户端连接字符串：

SOCKET_ENDPOINT = 'wss://******.azurewebsites.net/';

我在我的应用程序配置中打开了 websockets。

编辑：

所以我现在已经转动了每一块石头。甚至将库从 socket.io 切换到 ws。同样的问题。我想在尝试不同的事情时走得更远，现在我收到以下错误“Firefox 无法在 wss://*******.azurewebsites.net:8070/ 建立与服务器的连接。”

Edit2：http-upgrade 很好

这是错误

我猜您在Azure AppService中托管您的应用程序？

确保您在平台中打开了 websocket 选项：

AppService 资源 -> 设置 -> 常规设置选项卡 -> 平台设置部分
