问题描述：

Mixed Content: The page at 'https://AAAAAA.com' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://10.100.100.100:30000/'. This request has been blocked; this endpoint must be available over WSS.
index.1ea3d99d.js:4 DOMException: Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS.

问题分析

• HTTPS基于SSL依靠证书验证服务器身份，进行通信加密，我们的域名是https.所以非SSL验证的资源时浏览器可能会阻止。
• ws://调用websocket服务器或者请求http://*都会报错

问题解决

• 方案一：在前端将：ws:// 修改为：wss://，所有http改为https的资源
• 方案二：配置nginx代理 

  server
  {
      listen 80;
      listen 443 ssl;
      server_name 域名;
   
      ssl on;
      ssl_certificate 证书.crt;
      ssl_certificate_key 证书.key;
      ssl_session_timeout 5m;
      ssl_session_cache shared:SSL:50m;
      ssl_protocols SSLv3 SSLv2 TLSv1 TLSv1.1 TLSv1.2; # 按此协议配置
      ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
      ssl_prefer_server_ciphers on;
      
      location /wss/  {   
       proxy_pass http://127.0.0.1:82/;        # 指向部署websocket的项目
       proxy_http_version 1.1;    
       proxy_set_header Upgrade $http_upgrade;    
       proxy_set_header Connection "Upgrade";    
       proxy_set_header X-real-ip $remote_addr;
       proxy_set_header X-Forwarded-For $remote_addr;
       }
  }
