一、html代码：

<video id="my-video" class="video-js" playsinline controls preload="auto" controlslist="nodownload" controlslist="nofullscreen" width="100%" height="240"
           poster="upload/moviepic/2019-08-02/1564739500xyzp.png" data-setup="">
        <source src="" type="video/mp4">
        <source src="" type="video/ogg">
        <source src="" type="video/webm">
        <p class="vjs-no-js"> To view this video please enable javascript, and consider upgrading to a web browser that <a href="http://videojs.com/html5-video-support/" target="_blank">supports HTML5 video</a> </p>
    </video>

二、JavaScript代码：

 <script type="text/javascript">
    var video = document.getElementById("my-video");
    window.URL = window.URL || window.webkitURL;
    var xhr = new XMLHttpRequest();
    var play_url = ‘test.mp4‘;
    xhr.open("GET", play_url, true);
    xhr.responseType = "blob";
    xhr.onload = function() 
    if (this.status == 200) 
    var blob = this.response;
    console.log(blob);
    video.onload = function(e) 
    window.URL.revokeObjectURL(video.src);
    ;
    video.src = window.URL.createObjectURL(blob);
    
    
    xhr.send();
  </script>
