监控Nodejs的性能实例代码

window.onkeypress = window.onkeyup = window.onkeydown = this.handleKeyboardEvent

通过socekt把事件传递到服务端

handleKeyboardEvent (e) {
 this.socket && this.socket.emit('userevent', {
 type: 'keyboard',
 event: {
 type: e.type,
 keyName: e.key,
 keyCode: e.keyCode
 }
 })
 },
 handleMouseEvent (e) {
 this.socket && this.socket.emit('userevent', {
 type: 'mouse',
 event: {
 type: e.type,
 buttonType: e.buttons === 2 ? 'right' : 'left',
 x: e.clientX,
 y: e.clientY
 }
 })
 },

然后在服务端把事件取出来执行，执行事件使用的是 robot-js ：

const { Mouse, Point, Keyboard } = require('robot-js');
interface MouseEvent {
 type: string;
 buttonType: string;
 x: number;
 y: number;
}
interface KeyboardEvent {
 type: string;
 keyCode: number;
 keyName: string;
}
export default class EventExecuter {
 public mouse;
 public keyboard;
 public constructor(){
 this.mouse = new Mouse();
 this.keyboard = new Keyboard();
 }
 public executeKeyboardEvent(event: KeyboardEvent): void {
 switch(event.type) {
  case 'keydown':
  this.keyboard.press(event.keyCode);
  break;
  case 'keyup':
  this.keyboard.release(event.keyCode);
  break;
  case 'keypress':
  this.keyboard.click(event.keyCode);
  break;
  default: break;
 }
 }
 public executeMouseEvent(event): void {
 Mouse.setPos(new Point(event.x, event.y));
 const button = event.buttonType === 'left' ? 0 : 2
 switch(event.type) {
  case 'mousedown':
  this.mouse.press(button);
  break;
  case 'mousemove':
  break;
  case 'mouseup':
  this.mouse.release(button);
  break;
  case 'click':
  this.mouse.click(button);
  break;
  case 'dblclick':
  this.mouse.click(button);
  this.mouse.click(button);
  break;
  default: break;
 }
 }
 public exectue(eventInfo): void {
 console.log(eventInfo);
 switch (eventInfo.type) {
  case 'keyboard':
  this.executeKeyboardEvent(eventInfo.event);
  break;
  case 'mouse':
  this.executeMouseEvent(eventInfo.event);
  break;
  default: break;
 }
 }
}

至此，桌面监控和远程控制的客户端还有服务端的部分，以及两端的通信都已经实现了。思路其实并不麻烦，但细节还是很多的。有兴趣的同学可以把代码下下来跑跑试试，或者按着这个思路自己实现一遍，还是挺好玩的。
