javascript - Socket IO 命名空间不适用于 Express

Question

我尝试在后端设置命名空间，

const server = require("http").createServer(app);
const connectedUsers = {};

const io = require("socket.io")(server, {
  path: "/socket",
  serveClient: false,
  // below are engine.IO options
  pingInterval: 10000,
  pingTimeout: 5000,
  cookie: false
});

const singularConnection = io.of("/singular-socket");

singularConnection.on("connection", socket => {
    console.log("unique user connected with socket ID " + socket);
}

在我的客户端上，我尝试连接，

    const socket = io(GATEWAY, {
      path: "/socket/singular-socket",
      transports: ["websocket"],
      jsonp: false
    });

    socket.connect();

    socket.on("connect", () => {
      console.log("connected to socket server");
    });

我尝试了 URL 的不同变体，去掉了 /socket 并移动了其他内容，但我似乎无法让它工作。我在这里做错了什么？

我没有任何使用 socket.io 的经验，但是从文档来看......

要连接到命名空间，客户端代码如下所示。

const socket = io('http://localhost/admin', {
  path: '/mypath'
});

Here, the socket connects to the admin namespace, with the custom path mypath.

The request URLs will look like: localhost/mypath/?EIO=3&transport=polling&sid= (the namespace is sent as part of the payload).

按照上述几行，您的代码应该如下所示..

 const socket = io("http://localhost/singular-socket", {
      path: "/socket",
      transports: ["websocket"],
      jsonp: false
    })

其中 /singular-socket 是命名空间，/socket 是路径。
