Nginx反向代理后无法获取客户端真实IP地址怎么解决

时间：2023-05-14 16:26

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。
