Node.js '；无法获取'；在Nginx中使用代理传递时在Express上

我在DigitalOcean droplet上运行了两个网站，现在我已经在这两个网站上升级到https。在其中一个站点上，我向正在运行的节点服务器发出发送电子邮件的请求，但由于我启用了https，它会阻止此请求，因为它不是https（逻辑上）。因此，我尝试在启用了https的一个站点上使用节点mailserver作为代理传递

要进行测试，我要代理传递的节点服务器如下所示：

exports.start = () => {
    app.use(bodyParser.json());
    app.use(cors());
    app.get('/', (req, res) => res.send('Hello World!'));
    app.listen(4004, () => console.log('Server listening on port 4004'));
};

this.start();

server {

server_name mywebsite.nl www.website.nl;

location / {
    proxy_pass http://<PIVATE IP>:4000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}

location /ws {
    proxy_pass http://<PIVATE IP>:4002;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
}


location /mailmeister {
            proxy_pass http://<PIVATE IP>:4004;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
}


listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/mywebsite.nl/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/mywebsite.nl/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

}

我的Nginx

sites enabled/default

如下所示：

exports.start = () => {
    app.use(bodyParser.json());
    app.use(cors());
    app.get('/', (req, res) => res.send('Hello World!'));
    app.listen(4004, () => console.log('Server listening on port 4004'));
};

this.start();

server {

server_name mywebsite.nl www.website.nl;

location / {
    proxy_pass http://<PIVATE IP>:4000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}

location /ws {
    proxy_pass http://<PIVATE IP>:4002;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
}


location /mailmeister {
            proxy_pass http://<PIVATE IP>:4004;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
}


listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/mywebsite.nl/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/mywebsite.nl/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

}

有人知道如何解决这个问题吗？

curl localhost:4004/mailmeister

应该返回相同的404。因此，您需要将node.js配置为路由

/mailmeister

，或者将nginx配置为减少

/

的路径。请参见此操作，非常感谢。
