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。
Mixed Content: The page at ‘xxx‘ was loaded over HTTPS, but requested an insecure resource ‘xxx‘. This request has been blocked; the content must be served over HTTPS.
解决办法：
页面的head中加入：
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
意思是自动将http的不安全请求升级为https
Mixed Content: The page at 'xxx' was loaded over HTTPS, but requested an insecure resource 'xxx'.
