https域名连接websocket

问题：

        之前项目访问域名是http的，使用80端口，由于安全原因，改成https的域名。改成https后，前端websockt连接出现了了问题，报错：

1 Mixed Content: The page at 'https://xxx' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://xxx'. This request has been blocked; this endpoint must be available over WSS.

解决：

        看提示，是ws和wss的问题，讲前端websocket连接改成wss即可，同时需要修改nginx配置：

location /webSocket {
   proxy_pass  http://host;
   proxy_set_header Host $host;
   proxy_set_header Upgrade 'websocket';
   proxy_set_header Connection 'Upgrade';
}

最后贴一个在线测试websocket的网站，感觉不错：在线测试websocket
