Nodejs：事件机制

UserBean.js

var events = require("events");
var http = require("http");

function UserBean() {
    this.eventEmit = new events.EventEmitter();
    this.zhuce = function (req, res) {
        console.log('注册');
        req['uname'] = 'jack';
        req['pwd'] = 'bb';

        this.eventEmit.emit('zhuceSuc', 'aa', 'bb');//抛出事件消息
    },
        this.login = function (req, res) {
            console.log("登录");
            res.write("用户名：" + req['uname']);
            res.write("密码：" + req['pwd']);
            res.write("登录");
        }
}
module.exports = UserBean;
