nginx负载均衡中配置tomcat出现跨域的问题

 1.错误提示问题：

当nginx开启80跳转到443的时候，页面出现这个问题

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.

2.下图为配置nginx的配置文件

proxy_redirect          off;
proxy_set_header        Host $host;
proxy_set_header        X-Real-IP $remote_addr;  #获取真实ip
client_max_body_size    10m;
client_body_buffer_size 128k;
proxy_connect_timeout   90;
proxy_send_timeout      90;
proxy_read_timeout      90;
proxy_buffer_size       4k;
proxy_buffers           4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;

server {
   listen 80 default_server;

   server_name localhost;

   return 301 https://$server_name:6663$request_uri;
}

server {
    listen 443;

    server_name localhost;

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

#添加上面的这个红色即可解决。这个问题是由于tomcat重定向的时候丢失https了
