当https 连接中包含加载http资源时，浏览器会停止加载，UC浏览器console 会打印如下信息：
Mixed Content: The page at 'https://Xie.cn/' was loaded over HTTPS, but requested an insecure resource 'http://xm/m/vYby6nm?mobile=1'. This request has been blocked; the content must be served over HTTPS.
解决方案一：
在html文件的head标签中添加<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests"
当浏览器支持“upgrade-insecure-requests”属性时，会自动将http链接替换为https
解决方案二：
将连接中的算有http连接更换为https
