Python 通过SSH登录到Cisco无线控制器

我有一个可以工作的python脚本，它将登录到cisco设备（路由器/交换机），并从中提取您想要的任何信息。我现在正在为cisco wlc做同样的工作，但是要通过ssh连接到wlc，它需要一个“login as”名称以及“username/password”。我正在使用paramiko，不知道如何添加使用“登录身份”名称连接的额外步骤。是否有其他ssh模块允许我这样做

以下是通过ssh登录cisco wlc的示例：

登录身份：test

（思科控制器）

用户：测试

密码：****

这是使用paramiko.connect的文档：

连接（self，主机名，端口=22，用户名=None，密码=None， pkey=None，key\u filename=None，timeout=None，allow\u agent=True， 查找（关键字=真，压缩=假）

以下是我目前正在使用的代码，以防它有所帮助：

import web
import paramiko
import time

urls = (
        '/wlc', 'Index'
)

app = web.application(urls, globals())

render = web.template.render('templates/')

class Index(object):
        def GET(self):
                return render.hello_form()

        def POST(self):
                form = web.input(user=" ", passwd=" ", device=" ")
                user = form.user
                passwd = form.passwd
                device = form.device

                #Used to change term length to 0 making it so we don't need to hit a key to scroll through the output
                def disable_paging(remote_conn, command="terminal length 0", delay=1):

                        #Send an enter
                        remote_conn.send("\n")
                        #Send 'terminal length 0'
                        remote_conn.send(command)

                        #Wait for command to complete
                        time.sleep(delay)

                        #Read output
                        output = remote_conn.recv(65535)

                        return output

                #Have remote_conn_pre equal to the SSHClient module in paramiko
                remote_conn_pre = paramiko.SSHClient()

                #This allows us to bypass the ssh key popup that comes up when you ssh into a device for the first time
                remote_conn_pre.set_missing_host_key_policy(
                        paramiko.AutoAddPolicy())

                remote_conn_pre.connect(device,username=user, password=passwd) #Connect to the device using our defind parameters

                remote_conn = remote_conn_pre.invoke_shell() #invoke_shell module gives us access to talk to the device via the cli

                output = disable_paging(remote_conn) #Run the disable_paging function that sets term length to 0

                remote_conn.send("\n")
                remote_conn.send("sh ap inventory")
                remote_conn.send("\n")

                time.sleep(2)

                output = remote_conn.recv(65535) #Read all output given

                return output #print output to screen

                remote_conn_pre.close() #Close the SSH connection


if __name__ == "__main__":
        app.run()

和paramiko.transport玩了很多，但没能让它运行。最后，我尝试了.send（）信息，现在它给了我想要的输出：

import web
import paramiko
import time

urls = (
        '/wlc', 'Index'
)

app = web.application(urls, globals())

render = web.template.render('templates/')

class Index(object):
        def GET(self):
                return render.hello_form()

        def POST(self):
                #Retrieve user input from web form
                form = web.input(user=" ", passwd=" ", device=" ")
                user = form.user
                passwd = form.passwd
                device = form.device

                #Make it so we don't need to hit a key to scroll through the output
                def disable_paging(remote_conn, command="config paging disable", delay=1):

                        remote_conn.send(command)
                        remote_conn.send("\n")
                        time.sleep(delay)


                #Have remote_conn_pre equal to the SSHClient module in paramiko
                remote_conn_pre = paramiko.SSHClient()

                #This allows us to bypass the ssh key popup that comes up when you ssh into a device for the first time
                remote_conn_pre.set_missing_host_key_policy(
                        paramiko.AutoAddPolicy())

                remote_conn_pre.connect(device, username=user, password=passwd) #Connect to the device using our defind parameters

                remote_conn = remote_conn_pre.invoke_shell() #invoke_shell module gives us access to talk to the device via the cli

                #Log into the WLC
                remote_conn.send(user)
                remote_conn.send("\n")
                remote_conn.send(passwd)
                remote_conn.send("\n")

                #Run the disable_paging function
                output = disable_paging(remote_conn)

                #Run command
                remote_conn.send("sh ap summary")
                remote_conn.send("\n")

                #Some WLCs can be slow to show output, have program wait 5 seconds
                time.sleep(5)

                output = remote_conn.recv(65535) #Read all output given

                return output #print output to screen

                remote_conn.close() #Close the SSH connection


if __name__ == "__main__":
        app.run()

我的输出中省略了“Login As”字段，因此我不确定输入的是什么-可能只是来自

remote\u conn\u pre.connect（device，username=user，password=passwd）

的参数。不管怎样，现在我可以登录到设备上了，我可以开始解析输出以获得我想要的信息
