基于 Nginx 试着改了个 HTTPS，可以访问了，但是有一些资源没有变过来。

nginx 配置文件：

    server {
        #listen       80;
        listen       443 ssl;
        server_name  huyaxing.site; # 博客域名

        ssl_certificate /usr/local/nginx/conf/cert/4917509_huyaxing.site.pem;
        ssl_certificate_key /usr/local/nginx/conf/cert/4917509_huyaxing.site.key;
        ssl_session_timeout 5m;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
        ssl_prefer_server_ciphers on;

        access_log off;

        location / {
            proxy_pass http://backend$request_uri;
            proxy_set_header  Host $host:$server_port;
            proxy_set_header  X-Real-IP  $remote_addr;
            client_max_body_size  10m;
        }
    }

    server{
        listen 80;
        server_name huyaing.site www.huyaxing.site;
        rewrite ^(.*) https://$host$1 permanent;
    }

报错如图所示：
