Actually it can listen, but ports below 1024 require root privileges. This poses a security risk. So, you can use traffic forwarding. Use firewalld under CentOS 7

systemctl start  firewalld
firewall-cmd --add-forward-port=port=80:proto=tcp:toport=8080

其实是可以监听的，只是1024以下端口需要使用root权限。这样会有安全隐患。 所以，可以流量转发。 CentOS7下用firewalld

systemctl start  firewalld
firewall-cmd --add-forward-port=port=80:proto=tcp:toport=8080

Video page address: https://m.youku.com/video/id_XMzc1MDQ5NjcyMA==.html Interface domain: https://ups.youku.com Fields: data->stream->segs Sharded, order not yet clear. Might be difficult to crawl. iframe player (https also works)

<iframe height=498 width=510 src='http://player.youku.com/embed/XMzc1MDQ5NjcyMA==' frameborder=0 'allowfullscreen'></iframe>

The suffix is the page id, looks like it can be done in batch.

后面为页面id，看样子可以批量搞定。

项目用遇到了这个问题。 产生问题的原因：调用play之后执行pause。而此时play方法可能还没执行完。 查了一下谷歌这面有解决方案。 https://developers.google.com/web/updates/2017/06/play-request-was-interrupted 第一种解决方案

<video id="video" preload="none" src="https://example.com/file.mp4"></video>

<script>
  // Show loading animation.
  var playPromise = video.play();

  if (playPromise !== undefined) {
    playPromise.then(_ => {
      // Automatic playback started!
      // Show playing UI.
      // We can now safely pause video...
      video.pause();
    })
    .catch(error => {
      // Auto-play was prevented
      // Show paused UI.
    });
  }
</script>

第二种解决方案

<video id="video"></video>
<button id="button"></button>

<script>
  button.addEventListener('click', onButtonClick);

  function onButtonClick() {
    // This will allow us to play video later...
    video.load();
    fetchVideoAndPlay();
  }

  function fetchVideoAndPlay() {
    fetch('https://example.com/file.mp4')
    .then(response => response.blob())
    .then(blob => {
      video.srcObject = blob;
      return video.play();
    })
    .then(_ => {
      // Video playback started ;)
    })
    .catch(e => {
      // Video playback failed ;(
    })
  }
</script>

Encountered this problem in the project. The cause of the problem: pause is executed after calling play. But at this time the play method may not have finished execution. Checked that Google has a solution. https://developers.google.com/web/updates/2017/06/play-request-was-interrupted First solution

<video id="video" preload="none" src="https://example.com/file.mp4"></video>

<script>
  // Show loading animation.
  var playPromise = video.play();

  if (playPromise !== undefined) {
    playPromise.then(_ => {
      // Automatic playback started!
      // Show playing UI.
      // We can now safely pause video...
      video.pause();
    })
    .catch(error => {
      // Auto-play was prevented
      // Show paused UI.
    });
  }
</script>

Second solution

<video id="video"></video>
<button id="button"></button>

<script>
  button.addEventListener('click', onButtonClick);

  function onButtonClick() {
    // This will allow us to play video later...
    video.load();
    fetchVideoAndPlay();
  }

  function fetchVideoAndPlay() {
    fetch('https://example.com/file.mp4')
    .then(response => response.blob())
    .then(blob => {
      video.srcObject = blob;
      return video.play();
    })
    .then(_ => {
      // Video playback started ;)
    })
    .catch(e => {
      // Video playback failed ;(
    })
  }
</script>
