+## 抓包
+
+首先将手机上网功能配置成静态获取ip地址
+
+![请求](./img/1.jpg)
+
+查看本地的ip地址，我这边用的是无线网络所有，直接拿无线网络的参数配置
+
+![请求](./img/2.png)
+
+开启iptables流量重定向到mitmproxy
+
+    # 启用IP转发
+    sysctl -w net.ipv4.ip_forward=1
+    sysctl -w net.ipv6.conf.all.forwarding=1
+
+    # 禁用 ICMP 重定向
+    sysctl -w net.ipv4.conf.all.send_redirects=0
