Question

我正在使用Python 2.7.12并尝试使用此代码。

clientNet = []
class Client:
    def __init__(self, host, user, password):
        self.host = host
        self.user = user
        self.password = password
        self.session = self.connect()
    def connect(self):
        try:
            s = pxssh.pxssh()
            s.login(self.host, self.user, self.password)
            return s
        except Exception, e:
            print e
            print '[-] Error Connecting'
    def botnetCommand(command):
        for client in clientNet:
            output = client.send_command(command)
            print '[*] Output from ' + client.host
            print '[+] ' + output + '\n'
    def send_command(self, cmd):
        self.session.sendline(cmd)
        self.session.prompt()
        return self.session.before
    def addClient(host, user, password):
        client = Client(host, user, password)
        clientNet.append(client)

addClient('192.168.1.94','root','root')

并且

 Traceback (most recent call last):
  File "host.py", line 33, in <module>
    addClient('192.168.1.94','root','root')
NameError: name 'addClient' is not defined

我试图运行Client.addClient(..)，但没有解决我的问题。我想我需要一些帮助来理解这一点。如果它在Class里面怎么定义？

Answer 1

您需要首先使用类的实例来使用其方法：

client = Client('192.168.1.94','root','root')
client.addClient('192.168.1.95','root','root')

如果您将方法定义为：

，则可以使用静态方法

...
@staticmethod
def addClient(host, user, password):
    client = Client(host, user, password)
    clientNet.append(client)

并使用它：

Client.addClient(...)

无需制作实例。

名称未在Python中定义
