Question

我在运行这个python web脚本并在网页上打印出结果时遇到了一些麻烦。这是一个小型项目，我将在OpenWRT路由器上运行。

当无线客户端连接到接入点时，CGI脚本将针对从HTTP会话检索到的设备的IP地址运行，并显示是否有任何端口处于打开状态，可能会导致个人遭受某种攻击公共网络。

我可以通过wireshark数据包捕获确认端口扫描是否正常运行。

在那一刻我不断收到CGI错误，说明Nmap语法有错误 - 虽然我知道这可以在Python shell中使用

我得到的错误是 -

A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.

      args = ('nmap',)

这是我的代码

client = cgi.escape(os.environ["REMOTE_ADDR"])
print ('your IP Address is: ' + client)
nm = nmap.PortScanner()
nm.scan(client, '21')

for client in nm.scan():
    print('----------------------------------------------------')
    print('Host : %i' % (nm[client].all_protocols().keys))
