Js 音频律动 这段时间在独立写音乐项目，在学习过程中接触到了JS的音频律动，于是找到了以下项目以上是效果图下面分享代码：HTML结构<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> <link rel="stylesheet" href="index.css"> </head> <body style="background-color: #000;"> <div class="music-box"> <canvas class="my-canvas"></canvas> <button class="my-music-btn rotate"></button> </div> <script src="index.js"></script> </body> </html>CSS样式* { margin: 0;

网站提示Mixed Content: The page at was loaded over HTTPS怎么解决？ 当网站配置https访问方式后，某些功能无法使用，通过浏览器控制台查看报错提示为：Mixed Content: The page at 'https://www.12564.cn/dubber/kind.shtml' was loaded over HTTPS, but requested an insecure script 'http://www.12564.cn/jquery/2.0.0/jquery.min.js'. This request has been blocked; the content must be served over HTTPS.意思是：混合内容:“https://www.12564.cn/dubber/kind.shtml”页面是通过HTTPS加载的，但是请求了一个不安全的脚本“http://www.12564.cn/jquery/2.0.0/jquery.min.js”。此请求已被阻止;内容必须通过HTTPS提供。如下图：遇到这样的问题应该如何解决呢？其实很简单，找到报错对应的页面，在页面模板<head>中引入如下 <meta>标签内容即可。<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">这样系统会自动将http的不安全请求修改为https请求，就不会在报错了。如果你遇到了这样的问题，就试试看吧。
