如何用Chrome DevTools协议点击元素？

const WebSocket = require('ws');

// 连接到目标浏览器
const ws = new WebSocket('ws://localhost:9222/devtools/browser');

ws.on('open', () => {
  // 发送获取页面标签树的命令
  ws.send(JSON.stringify({ id: 1, method: 'DOM.getDocument' }));
});

ws.on('message', (message) => {
  const response = JSON.parse(message);

  if (response.id === 1 && response.result) {
    const root = response.result.root;

    // 查找目标元素
    ws.send(JSON.stringify({ id: 2, method: 'DOM.querySelector', params: { nodeId: root.nodeId, selector: 'your-selector' } }));
  } else if (response.id === 2 && response.result) {
    const nodeId = response.result.nodeId;

    // 获取目标元素的坐标
    ws.send(JSON.stringify({ id: 3, method: 'DOM.getBoxModel', params: { nodeId } }));
  } else if (response.id === 3 && response.result) {
    const { model } = response.result;

    // 模拟点击事件
    ws.send(JSON.stringify({ id: 4, method: 'Input.dispatchMouseEvent', params: { type: 'mousePressed', x: model.border[0], y: model.border[1], button: 'left', clickCount: 1 } }));
    ws.send(JSON.stringify({ id: 5, method: 'Input.dispatchMouseEvent', params: { type: 'mouseReleased', x: model.border[0], y: model.border[1], button: 'left', clickCount: 1 } }));

    // 关闭连接
    ws.close();
  }
});
