sniff(iface='WLAN', prn=handle_packet, filter='tcp and port 3306')我想在这段代码中加上tcp and port 80

你可以修改 filter 参数来实现该功能,如下所示:
```
sniff(iface='WLAN', prn=handle_packet, filter='tcp and (port 80 or port 3306)')
```
这样就可以同时捕获 TCP 协议的 80 端口和 3306 端口的数据包了。注意括号的使用,以避免逻辑错误。

如果要监听本地的无线网卡,可以将`iface`参数修改为对应的无线网卡名称,例如:
```
sniff(iface='wlan0', prn=handle_packet, filter='tcp or udp')
```
其中,`wlan0`为无线网卡的名称,可以通过命令`ifconfig`或`ipconfig`查看。

这个错误的意思是找不到TCP层。这可能是因为你的抓包过滤器只包含了TCP或UDP,但实际上有些包可能没有这些层。你可以尝试使用更宽泛的过滤器,例如:filter='port 3306'。或者你可以使用更高级的过滤器来检查包是否包含TCP层,例如:filter='tcp and port 3306'。这样可以确保你只处理包含TCP层和端口3306的数据包。
