Express 如何在HTTPS nginx中访问用户IP

目前，通过HTTP访问我的站点时，客户端IP位于X-Forwarded-For标头中 以下格式为“192.132.41.2、192.168.0.4”

但是，当通过HTTPS访问站点时，只有服务器IP通过。 我如何通过HTTPS获得用户IP

server {
        #listen 443 ssl http2;
        listen 443;
        ssl on;
        ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
        include snippets/acme;
        server_name example.com;
        location / {
                include  /etc/nginx/mime.types;
                proxy_set_header  X-Real-IP         $remote_addr;
                #proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_pass http://localhost:3000;
        }
}

server {
        listen 80;
        include snippets/acme;
       # prevent direct IP access
       if ($host != "example.com") {
               return 404;
       }
        server_name example.com;

        location / {
                include  /etc/nginx/mime.types;
                proxy_set_header  X-Real-IP         $remote_addr;
                #proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_pass http://localhost:3000;
        }
}

如果希望Nginx使用

X-Forwarded-For

设置

$remote\u addr

，则需要使用。
