Question

我正在实施websockets并在我的项目中也安装了ws软件包，但是当我初始化const WSS= new WebSocketServer({port: 3232})时，typeError显示为WebSocketServer is not a constructor。

const WebSocketServer = require('ws').server;
const WSS = new WebSocketServer({port: 3232});

WSS.on('connection',(ws)=>{
  console.log('we are connected');
});

显示

typeError webSocketServer is not a constructor

Answer 1

它是.Server，而不是.server。

这是一个例子：

const WebSocket = require('ws');

const wss = new WebSocket.Server({
  port: 8080
})

或保留您的格式：

const WebSocketServer = require('ws').Server;
const WSS = new WebSocketServer({port: 3232});

WSS.on('connection',(ws)=>{
  console.log('we are connected');
});

谅解`WebSocketServer`中的问题不是一个类
