vue项目使用socket.io-client客户端

安装socket.io-client模块
npm install socket.io-client --save

新建一个js文件,配置socket:

import Vue from ‘vue’;
import io from ‘socket.io-client’; //引入socket.io-client

export default new Vue({
data: {
hasRealAlarm: false,
socket: null,
nInstance: null,

// console.log(‘初始化:socket’, socket);

console.log(‘open:’, data);
const userName = {
userName: this.getuserName(), //获取登录缓存的用户
};
console.log(‘userName:’, userName);
if (this.getuserName() !== null) {
socket.emit(‘addUser’, userName); //推送用户账号给后端socket
}
});

		this.socket.on('close', () => {
			console.log('socket连接关闭');
		});

		/* Listeners */
