跟踪%视频观看不工作(时间更新和vimeo)。为什么？

// 嵌入Vimeo视频
<iframe id="vimeoPlayer" src="https://player.vimeo.com/video/VIDEO_ID" width="640" height="360" frameborder="0" allow="autoplay; fullscreen" allowfullscreen></iframe>

// 跟踪代码
<script>
  var vimeoPlayer = document.getElementById('vimeoPlayer');
  var player = new Vimeo.Player(vimeoPlayer);

  player.on('play', function() {
    console.log('Video started playing');
    // 发送跟踪数据到服务器
    sendTrackingData('play');
  });

  player.on('pause', function() {
    console.log('Video paused');
    sendTrackingData('pause');
  });

  player.on('ended', function() {
    console.log('Video ended');
    sendTrackingData('ended');
  });

  function sendTrackingData(event) {
    fetch('https://your-tracking-server.com/track', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        videoId: 'VIDEO_ID',
        event: event,
        timestamp: new Date().getTime()
      })
    }).then(response => response.json())
      .then(data => {
        console.log('Tracking data sent:', data);
      }).catch(error => {
        console.error('Error sending tracking data:', error);
      });
  }
</script>
