通过融云 WebSDK 简单了解 WebSocket

const Port = '2928';

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

wss.on('connection', function (ws, event) {

  const url = event.url; // url 为客户端链接地址, 可拼接参数. 比如融云拼接了 appkey 等信息: ?appid=n19xxxxxx&token=xxxxxxxx

​

  /* 监听链接关闭 */

  ws.on('close', () => {

    // 此 ws 链接已断开. do something

  });

});

const Port = '2928';

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

wss.on('connection', function (ws, event) {

  ws.on('message', function (data) {

    console.log('data', data); // 收到客户端发送的数据 do something

  });

});

const Port = '2928';

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

wss.on('connection', function (ws, event) {

  ws.send('some data');

});

const socket = new WebSocket('ws://localhost:2928');

socket.addEventListener('open', function (event) {

  // 链接成功, do something

});

const socket = new WebSocket('ws://localhost:2928');

socket.addEventListener('message', function (event) {

  console.log('收到服务端发送的数据', event.data);

});

const socket = new WebSocket('ws://localhost:2928');

socket.addEventListener('open', function (event) {

  socket.send('some data'); // 链接后, 调用 send 发送

});
