在升级https的过程中，出现如下问题：
Mixed Content: The page at ‘https://www.xxx.com/denglu.html‘ was loaded over HTTPS, but requested an insecure script ‘http://qzonestyle.gtimg.cn/qzone/openapi/qc-1.0.1.js‘. This request has been blocked; the content must be served over HTTPS.
问题抛出：如何在HTTPS 网页中引入HTTP资源： Mixed Content？
问题原因：HTTPS页面里动态的引入HTTP资源，比如引入一个js文件，会被直接block掉的.在HTTPS页面里通过AJAX的方式请求HTTP资源，也会被直接block掉的。
解决方案：
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
可以在相应的页面的<head>里加上这句代码，意思是自动将http的不安全请求升级为https
