我有一个这样的课:

import net from 'net';
import {EventEmitter} from 'events';
import Promise from 'bluebird';

class MyClass extends EventEmitter {
    constructor(host = 'localhost', port = 10011) {
        super(EventEmitter);
        this.host = host;
        this.port = port;
        this.socket = null;
        this.connect();
    }
    connect() {
        this.socket = net.connect(this.port, this.host);
        this.socket.on('connect', this.handle.bind(this));
    }
    handle(data) {
        this.socket.on('data', data => {

        });
    }
    send(data) {
        this.socket.write(data);
    }
}
