问题描述：

nginx代理tomcat服务器,访问Nginx用Https,代理用http,但是tomcat重定向的页面无法访问

流程：

问题描述：用户–https–>Nginx–http–>Tomcat

错误信息：

Mixed Content: The page at ‘https://…/#’ was loaded over HTTPS,
but requested an insecure form action ‘http://…//’. This request
has been blocked; the content must be served over HTTPS.

解决：
这是因为tomcat重定向的时候给你变成http了。
加个 proxy_redirect

proxy_pass http://127.0.0.1:8080/;
proxy_redirect ~^http://([^:]+)(:\d+)?(.*)$  https://$1$3;
