我无法在Digital Ocean中设置WebSocket服务器。
为了这个问题,我正在为domain.com更改我的实际域名。
我基本上有一个NodeJs WebSocket服务器,我试图连接到我在Heroku托管的React应用。尝试连接时出现以下错误:
WebSocket connection to 'wss://domain.com/' failed: Error during WebSocket handshake: Unexpected response code: 200
这是我的服务器输入代码:
const PORT = process.env.PORT || 8080
const privateKey = fs.readFileSync('/etc/letsencrypt/live/domain.com/privkey.pem', 'utf-8')
const certificate = fs.readFileSync('/etc/letsencrypt/live/domain.com/cert.pem', 'utf-8')
const credentials = { key: privateKey, cert: certificate }
const server = express()
const httpsServer = https.createServer(credentials, server)
httpsServer.listen(PORT)
this.wss = new WebSocket.Server({ server: httpsServer })
我使用cert-bot来保护我的连接,因为Heroku是必须的。这是我的Nginx默认配置文件,位于/ etc / nginx / sites-available / default
server {
# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.
# See: https://bugs.debian.org/765782
#
# Self signed certs generated by the ssl-cert package
# Don't use them in a production server!
#
# include snippets/snakeoil.conf;
root /var/www/html;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html;
server_name domain.com www.domain.com;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
# pass PHP scripts to FastCGI server
#
#location ~ \.php$ {
# include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
# fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
# # With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/domain.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/domain.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
}
我也更改了我的UFW配置。这是sudo ufw状态的输出
Nginx Full ALLOW Anywhere
22/tcp ALLOW Anywhere
Nginx Full (v6) ALLOW Anywhere (v6)
22/tcp (v6) ALLOW Anywhere (v6)
请明确说明,我并不是真正使用domain.com。我只是在当前有关隐私问题的问题中更改了它,:D
希望任何人都可以指出正确的方向。不太确定我要去哪里错了。
