我有一个与此类似的设置：

var WebSocketServer = require("ws").Server,
    express = require("express"),
    http = require("http"),
    app = express(),
    server = http.createServer(app);

app.post("/login", login);
app.get("/...", callSomething);
// ...

server.listen(8000);


var wss = new WebSocketServer({server: server});

wss.on("connection", function(ws){
   // ...
});

我想将WebSocketServer放在特定的路径下，例如"...com/whatever"。问题是如何设置路径？可能吗？
