    server_name    www.xxx.com;
    
    # ssl证书的pem文件路径
    ssl_certificate       /home/cert.pem;
    # ssl证书的key文件路径
    ssl_certificate_key   /home/cert.key;
    
    # 设置共享会话缓存大小,默认1m
    ssl_session_cache     shared:SSL:10m;
    # 设置会话超时时间
    ssl_session_timeout   5m;
    # 配置SSL加密算法,默认"HIGH:!aNULL:!MD5"
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    # 优先采取服务器算法
    ssl_prefer_server_ciphers   on;
    
    # 匹配"/websocket/"规则
    location /websocket/ {
        # 转发地址
        proxy_pass http://localhost:9068;                
        proxy_http_version 1.1;        
        # 设置读取超时时间(单位:秒,默认60),避免nginx超时
        proxy_read_timeout 7200;
        proxy_redirect off;
        proxy_set_header Upgrade $http_upgrade;
