在javascript中使用setInterval时,请保持在类的范围内

我有一个类来管理我与NodeJS中套接字的连接。每当连接无法建立或丢失时,我想设置一个间隔,以保持重试连接。然而,如果我打电话给 setInterval 函数,我作为引用传递的方法现在在 . 我的套接字类中的方法现在不再可用,除非有一些巨大的嵌套语句,否则我无法重新连接套接字。主要问题是我在 connect() 方法现在在的范围内不再可用 setInterval()

你有什么想法可以让它工作吗?

class SocketClass {

  constructor() {
    this.socket = {}
    this.port = 0
    this.host = ''
    this.intervalID = null
  }


  connect(port, host) {
    this.port = port;
    this.host = host;
    this.connectImpl()
    this.socket.on('error', () => this.errorEventHandler())
    this.socket.on('close', () => this.closeEventHandler())
  }

  connectEventHandler() {
    console.log('Connected!')
    if (this.intervalID !== null) {
      clearInterval(this.intervalID);
    }
  }

  errorEventHandler() {
    console.log('Error!')
  }

  connectImpl() {
    console.log('Trying to connect...')
    this.socket = require('net').Socket().connect(this.port, this.host)
  }

  closeEventHandler() {
    console.log('Connection lost')
    this.intervalID = setInterval(() => this.connectImpl(), 1000)
    // this.connectImpl() is called correctly but the event 
    // handlers defined in the constructor are now no longer bound
  }

}

export default new SocketClass
