Nginx 真實 IP 日誌記錄不起作用？

我有以下 nginx 配置：

worker_processes auto;
daemon off;
error_log /dev/stdout warn;
include /etc/nginx/modules/*.conf;

events {

}

http {
 real_ip_header X-Forwarded-For;
 real_ip_recursive on;
 set_real_ip_from 192.168.2.1;

 server_tokens off;
 default_type application/octet-stream;
 log_format json_combined escape=json
 '{'
 '"remote_addr":"$remote_addr",'
 '"request":"$request",'
 '"real_ip": "$realip_remote_addr",'
 '"http_x_real_ip": "$http_x_real_ip"'
 '}';
 access_log /dev/stdout json_combined;

 server {
   location / {
     root /content/;
   }  
 }
include /etc/nginx/conf.d/*.conf;
}

我的期望是該realip_remote_addr變數應該在X-Forwarded-For標題中具有最後一個不受信任的地址。但是，當我提出這樣的請求時：

$ curl -v --header "X-Forwarded-For:10.1.1.1,192.168.2.1" localhost

日誌顯示127.0.0.0.1和remote_addr變數realip_remote_addr。

這是我的 nginx 版本：

任何想法我做錯了什麼？

該設置set_real_ip_from 192.168.2.1意味著 nginx 將僅信任X-Forwarded-For從該 IP 地址發送的標頭。在您的測試中，標頭來自 127.0.0.1，因此 nginx 會忽略該標頭。
