我在远程服务器（数字海洋）上部署了一个react应用程序，我希望能够从react客户端访问服务器的localhost。
我试过用Nginx设置一个反向代理，但是我得到了一个糟糕的404。
该网站已部署，https://www.jonasgroenbek.com。当您选择摇滚，剪刀或纸张然后按钮来对抗AI时，问题会出现在游戏部分下面。
这是我在Nginx内部启用的网站
server {
root /var/www/jonasgroenbek.com/build;
index index.html;
server_name jonasgroenbek.com www.jonasgroenbek.com;
location / {
try_files $uri $uri/ =404;
}
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/jonasgroenbek.com/fullchain.pem; # managed b$
ssl_certificate_key /etc/letsencrypt/live/jonasgroenbek.com/privkey.pem; # managed$
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
location /game {
rewrite /game/(.*) /$1 break;
proxy_pass http://localhost:1234;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
server {
if ($host = www.jonasgroenbek.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = jonasgroenbek.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 default_server;
listen [::]:80 default_server;
server_name jonasgroenbek.com www.jonasgroenbek.com;
return 404; # managed by Certbot
}
这是node.js快递服务正在侦听的端口和路径：
app.listen(PORT, function(){
console.log(`listening on port:${PORT}...`)
})
app.get("/game/play/:choice", function(req,res){
pythonProcess = spawn('python',["./script.py", req.params.choice]);
pythonProcess.stdout.on('data', function(data) {
res.status(200).send(data.toString('utf-8'))})
})
这是我从反应应用程序中获取的方式
fetch(`104.248.28.88/game/play/rock`)
问题是要发现的，因为我正在慢慢失去理智。
编辑
我试过两个
fetch("104.248.28.88/game/play/rock")
产生此错误消息：Game.js:46 GET https://jonasgroenbek.com/jonasgroenbek.com/game/play/rock 404 (Not Found)
和fetch("jonasgroenbek.com/play/rock")
产生此错误消息：
Game.js:46 GET https://jonasgroenbek.com/jonasgroenbek.com/game/play/rock 404 (Not Found)
试图通过邮递员访问它
jonasgroenbek.com/game/play/rock
给出以下错误消息：
<html>
<head>
<title>404 Not Found</title>
</head>
<body bgcolor="white">
<center>
<h1>404 Not Found</h1>
</center>
<hr>
<center>nginx/1.14.0 (Ubuntu)</center>
</body>
</html>
问题是您使用的是IP地址而不是您在server_name指令上设置的域。因此，不是使用该站点配置，而是使用默认的Nginx配置。
尝试：
fetch('https://jonasgroenbek.com/game/play/rock')
你也可以放弃：
rewrite /game/(.*) /$1 break;
