IPFS是不提供https服务的，所以，必须使用nginx的反向代理提供https！

前提：nginx的https已由Certbot配置好了，再加上以下代码即可。

server {
    server_name example.com;    
    location / {
        proxy_pass http://127.0.0.1:8080;       
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    listen 8081 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
    listen [::]:9001 ssl ipv6only=on; # managed by Certbot
    listen 9001 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    server_name  example.com;
    location / {
        proxy_pass http://127.0.0.1:9000;
     }
}
