前言
做一个小程序项目,3d多人聊天室互动,有两台服务器,windows系统和contos7
分别用来写小程序逻辑和部署socket.io
由于小程序里面都是https的请求,所以socket.io请求需要从ws(未加密)改成wws(加密)
下面应该是使用nginx反向代码解决这wss访问问题
两个简单问题解决记录
一、socket使用加密访问
由于小程序里面都是https访问,直接访问socket监听的3000端口会报错:
Mixed Content: The page at 'https://xxx/test/index.html' was loaded over HTTPS, but attempted to connect to the insecure WebSocket endpoint 'ws://xxx:3000/socket.io/?EIO=4&transport=websocket'. This request has been blocked; this endpoint must be available over WSS.
在centos7上面,使用nginx反向代理可以解决(反向代理真的好用!)
一键安装nginx
sudo yum install -y nginx
直接修改默认的配置文件如下:(自备ssl证书)
就是把443端口注释开启,最后加了一个反向代理到本地的3000端口,也就是我socket监听的端口

二、nginx反向代理之后socket请求跨域设置失效
本来socket已经配置了跨域了,但是反向代理后依旧还有跨域报错
上面的配置文件已经写了,在反向代理之前设置nginx跨域即可文章来源:https://www.toymoban.com/news/detail-426603.html
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
总结
解决办法就是nginx 监听443端口配置证书,反向代理socket服务文章来源地址https://www.toymoban.com/news/detail-426603.html
