本地主机ssl的Nginx配置

Question

我无法为我的Nginx服务器获得正确的配置。 我使用Certbot来配置SSL。我制作了一个在localhost：3000上运行的节点服务器。我可以使用http访问服务器（我使用proxy_pass），但是我想使用SSL。我找到了如何生成证书（https://letsencrypt.org/docs/certificates-for-localhost/），但是我不知道要在nginx配置中进行哪些更改才能在本地主机上使用它。有什么帮助吗？ :)这是我的配置：

upstream api {
    server localhost:3000;
}

server {
    server_name example.com;
    root /home/ubuntu/dev/example.com;
    index index.html;
    try_files $uri $uri/ /index.html;

    listen 443 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

    location /api/v1 {
        proxy_pass https://api;
        rewrite ^/api/v1/?(.*) /$1 break;
    }

}

server {
    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80;
    server_name example.com;
    return 404; # managed by Certbot
}
