nginx 导致websocket无法连接的解决办法

答：在config配置文件中

map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}

server {
    listen 443 ssl;
    server_name your_domain.com;

    ssl_certificate /path/to/ssl_certificate.crt;
    ssl_certificate_key /path/to/ssl_certificate.key;

    location / {
        proxy_pass http://localhost:8082;  # WebSocket应用的地址
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }
}
