javascript实现blob加密视频源地址的方法

一、HTML代码：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?imageMogr2/format/webp" 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>

三、效果图如下：

当然也可以用别的方法实现 XOR算法等。。。
