Python调用socket.bind()传2个参数报错仅接受1个如何解决

Python标准库socket模块的bind()方法仅接受1个参数，该参数为包含绑定地址与端口的元组，不能分开传入IP、端口两个独立参数。另外你原有代码中传入参数的顺序也有误，元组内需要先写IP地址，再写端口。

将原有绑定套接字的代码行：

socket_connection.bind(port,ip_add)

修改为：

socket_connection.bind((ip_add, port))

另外你现有代码中两处格式化打印的字符串没有预留占位符，format()参数无法正常插入，同时为了避免套接字初始化失败时finally块调用close()报错，建议同步做对应调整。

from socket import *

def main ():
    print('''========================================================================== ''')
    print('''  [-]   S T A R T I N G      T H E        D E C O Y        S E R V E R  [-] ''')
    print('''========================================================================== ''')
    ip_add = "192.168.43.195"
    port = 80
    socket_connection = None
    try :
        socket_connection=socket(AF_INET,SOCK_STREAM)
        # 修正绑定逻辑，传入IP+端口的元组
        socket_connection.bind((ip_add, port))
        socket_connection.listen(10)
        while 1 :
            attacker_connection,attacker_addr = socket_connection.accept()
            # 补充格式化占位符
            print("Decoy Server Is Created on The Attacker: {}".format(attacker_addr[0]))
            attacker_connection.send(b"<h1> Unable to connect from The server Please Check Your Network Connection </h1>")
            data = attacker_connection.recv(3072)
            print(data)
    except error as identifier:
        # 补充格式化占位符
        print("An Error Was Encounterd While Deploying A Decoy Server: {}".format(identifier))
    except KeyboardInterrupt as ky :
        print("Decoy Server Stopped By The User")
        print(" [+]..../ Exiting \....[+] ")
    finally:
        if socket_connection:
            socket_connection.close()
if __name__ == '__main__':
      main()
