①添加
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Host $host;
②设置跨域请求
#允许跨域请求的域，* 代表所有
add_header 'Access-Control-Allow-Origin' https://ybt.snut.edu.cn;
#允许带上cookie请求
add_header 'Access-Control-Allow-Credentials' 'true';
#允许请求的方法，比如 GET/POST/PUT/DELETE
add_header 'Access-Control-Allow-Methods' *;
#允许请求的header
add_header 'Access-Control-Allow-Headers' *;
websocket能够正常使用，不报错
