我是 python 新手，我有一個問題，我幾天都無法解決，我根本不明白錯誤是什么。我正在撰寫一個基于 Nmap 程式和同名庫的程式，其功能是掃描某些 IP 地址串列的開放埠。我正在嘗試通過字典來實作這一點，當我對埠的靜態變數執行所有操作時，一切都很好，但是當程式掃描每個地址的埠時，會在掃描周期的第二次迭代中發出這樣的錯誤。
'dict' object is not callable
File "C:\Users\Duoksi\Desktop\codes\python\NmapScanPy\test.py", line 47, in ScanPorts
result = nmap.scan_command(ip, arg = attribute)
下面是功能代碼。您還可以使用以下命令安裝庫： pip install python3-nmap
import nmap3
def Portscan():
nmap = nmap3.Nmap()
attribute = "-p "
port = input("Enter ports(ex. 80,443)\n")
attribute = str(port)
ipport = dict()
IPrange = ['93.187.72.82', '93.187.72.94', '93.187.72.115', '93.187.72.241', '93.187.72.19', '93.187.72.59', '93.187.72.208',
'93.187.72.179', '93.187.72.24', '93.187.72.137', '93.187.72.136', '93.187.72.130']
for ip in IPrange:
result = nmap.scan_command(ip, arg = attribute)
resultclean = re.findall('\'protocol\': \'\w \', \'portid\': \'\w \', \'state\': \'\w \'', str(result))
for res in resultclean:
ipport.setdefault(ip, []).append(res)
return ipport
我期望 的輸出：輸出圖片
uj5u.com熱心網友回復：
未修改的scan_command方法回傳一個代表 XML 樹的xml.etree.ElementTree.Element物件，如下所示：
<nmaprun scanner="nmap" args="/usr/bin/nmap -oX - -p 80 93.187.72.82" start="1648151628" startstr="Thu Mar 24 20:53:48 2022" version="7.80" xmloutputversion="1.04">

這是獲取protocol,portid并state從中獲取的代碼：
import nmap3
IP_RANGE = [
'93.187.72.82', '93.187.72.94', '93.187.72.115', '93.187.72.241', '93.187.72.19', '93.187.72.59',
'93.187.72.208', '93.187.72.179', '93.187.72.24', '93.187.72.137', '93.187.72.136', '93.187.72.130',
]
def scan_one_ip(ip: str, port: str) -> list[str]:
result = nmap3.Nmap().scan_command(ip, arg=f"-p {port}")
port_element = result.find("./host/ports/port")
return [
port_element.get("protocol"),
port_element.get("portid"),
port_element.find("state").get("state"),
]
def scan_port(port: str) -> dict[str, list[str]]:
return {ip: scan_one_ip(ip, port) for ip in IP_RANGE}
def main():
port = input("Enter ports (ex. 80,443)\n")
print(scan_port(port))
if __name__ == '__main__':
main()
