birt 内嵌iframe 提示session 过期处理

birt 设置base_url, 注意要使用https，不然会有很多麻烦, 比如主站是https，iframe 是http，就会报错

# /var/lib/tomcat9/webapps/birt/WEB-INF/viewer.properties
# configurable variable for JSP base href. Please uncomment the below line.
base_url=https://birt.test.com/

配置nginx，

server {listen 443 ssl;server_name birt.test.com;ssl_certificate     /etc/nginx/ssl/birt.test.com.cer;ssl_certificate_key /etc/nginx/ssl/birt.test.com.key;ssl_protocols       TLSv1.2 TLSv1.3;ssl_ciphers         HIGH:!aNULL:!MD5;ssl_session_cache   shared:SSL:10m;ssl_session_timeout 10m;location /birt/ {proxy_pass http://127.0.0.1:8080/birt/;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;# 允许跨域访问add_header Access-Control-Allow-Origin "*";add_header Access-Control-Allow-Methods "GET, POST, OPTIONS";add_header Access-Control-Allow-Headers "*";add_header Access-Control-Allow-Credentials "true";# 透传 JSESSIONIDproxy_cookie_path / "/; Secure; HttpOnly; SameSite=None";}
