JSP http 升级 https 遇到的问题

最近升级 https

发现有一个页面无法打开：调试显示

Blocked loading mixed active content “http://webapi.amap.com/maps?v=1.3&key=6efd769f7bd2a487b136eee3f80d6bc0”
Mixed Content: The page at '<URL>' was loaded over HTTPS, but requested an insecure script '<URL>'. This request has been blocked; the content must be served over HTTPS.

提示服务必须为https，检查原来请求高德地址是http，全改成https

问题解决。
