Websocket 60秒断开，连接不稳定

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

参考：

Nginx代理配置

Nginx重连时间
