+### 获取请求ip
+<!--rehype:wrap-class=col-span-3-->
+
+```nginx
+server {
+	listen 80;
+	server_name xxx.top;
+
+	location / {
+		access_log /data/logs/nginx/json_ip.log json;
+		proxy_set_header Host $http_host;
+        proxy_set_header X-Real-Ip $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_pass http://127.0.0.1:9999;
+	}
+}
+
+server {
+	listen 9999;
+
+	location / {
+		access_log off;
+		default_type application/json;
+		return 200 "{\"ip\":\"$http_X_Real_Ip\"}";
+	}
+}
+```
+
+### 判断请求参数
+<!--rehype:wrap-class=col-span-3-->
+
+```nginx
+# 判断多个参数示例
+set $flagts 0;
+if ( $arg_aaa ~ "^aaa" ) {
+    set $flagts "${flagts}1";
+}
+if ( $arg_bbb ~ "^bbb" ) {
+    set $flagts "${flagts}1";
+}
+if ( $flagts = "011" ) {
+    return 200;
+}
