我应该在nginx / express中对https做什么？

Question

我的目的...

1. 客户端------> 80端口。
2. 80 ----------> 443（由nginx提供，用于https）
3. 443 ---------> 3000（由nginx提供）
4. express服务器正在端口3000上等待。

当我尝试连接到域名时，我刚得到cannot connect site, domain.com deny your access

nginx设置-/ etc / nginx / sites-available / default

nodejs设置

require('@babel/polyfill'); 
const app = require('./app'); 
const debug = require('debug')('learn-express:server'); 
const http = require('http'); 
require('dotenv').config();

const port = normalizePort(process.env.http_port); 
app.listen(port, () => {
         console.log('Server is running on port '+port);
