[网络协议]Websocket连接不稳定，60秒断开重连

本地测试都是正常的，线上测试总是过一会就断开…

线上新增了https协议，导致页面中的链接必须也是ssl

Websocket链接地址从ws://ws.xxx.com改成了wss://ws.xxx.com

最开始http的配置如下：

server {
    listen 80;
    server_name ws.xxx.com;

    location / {
        proxy_pass http://127.0.0.1:8110;
        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 Connection $connection_upgrade;
        proxy_set_header Upgrade $http_upgrade;
        client_max_body_size 1000m;
        proxy_read_timeout 360s;
    }
}

升级到https后的ssl配置：

server {
    listen 443 ssl;
    server_name ws.xxx.com;

    ssl_certificate /usr/local/nginx/ws.xxx.com.crt;
    ssl_certificate_key /usr/local/nginx/ws.xxx.com.key;

    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers  on;

    location / {
        proxy_pass http://127.0.0.1:8110;
        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 Connection $connection_upgrade;
        proxy_set_header Upgrade $http_upgrade;
        client_max_body_size 1000m;
    }
}

线上Nginx新增ssl代理的时候，没有设置proxy_read_timeout

正确做法应该是proxy_read_timeout配置大于Websocket心跳时间
