1、java代码

2、nginx需要进行相应修改,重点 proxy_set_header
server { listen xxxx; server_name 127.0.0.1; # 静态页面目录 root xxxxxxxxxx; # 默认首页 index login.html; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header REMOTE-HOST $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; add_header Access-Control-Allow-Origin *; add_header Access-Control-Allow-Methods 'GET,POST'; add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization'; #proxy_cookie_path /* /*; client_max_body_size 100m; location / { proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header REMOTE-HOST $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; add_header Access-Control-Allow-Origin *; add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization'; add_header Access-Control-Allow-Methods GET,POST,OPTIONS; ...... } }
