当我们使用 Nginx 代理转发服务后，会发现我们无法获取客户端的真实IP地址，从而无法获取客户端的地理位置等信息。
1、原始配置文件如下
worker_processes 1;events {worker_connections 1024;}http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;server {listen 80;server_name localhost;location / {root html;index index.html index.htm;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}}}
2、配置转发后
worker_processes 1;events {worker_connections 1024;}http {include mime.types;default_type application/octet-stream;sendfile on;keepalive_timeout 65;server {listen 80;server_name localhost;location / {root html;index index.html index.htm;}# 代理转发location /api/{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 $proxy_add_x_forwarded_for;proxy_set_header Public-Network-URL http://$http_host$request_uri;proxy_pass http://localhost:8080/;}error_page 500 502 503 504 /50x.html;location = /50x.html {root html;}}}
这样，我们就将客户端的头部信息一起转发过去，就能获取用户的真实 IP 地址了
