API介绍

paramiko提供了3个类，transport、channel、sshclient，sshclient可以看做是前两个类的高级封装

 

示例

transport

 

import paramiko

import time

ip, port, username, password ='192.168.1.7',22,'root','123456'

trans = paramiko.Transport((ip,port)) # ssh.connect集成了这2个命令

trans.connect(username=username,password=password)

chan = trans.open_session() #ssh.invoke_shell()集成了这3个命令

chan.get_pty()

chan.invoke_shell()

chan.send('cd /tmp\r')

chan.send('ll\r')

time.sleep(1)

out = chan.recv(1024)

print(out.decode())

chan.close()

trans.close()

 

sshclient.exec_command执行一条命令

 

import paramiko

ip, port, username, password,command='192.168.1.8',22,'root','123456','date'

ssh = paramiko.SSHClient() #创建一个ssh对象

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) #选择yes，接受key

ssh.connect(hostname=ip, port=port, username=username, password=password,timeout=5) #连接服务器

stdin, stdout, stderr = ssh.exec_command(command,get_pty=True) #执行一条命令

print(stdout.read().decode('utf-8')) #获取执行命令的结果

ssh.close() #关闭连接

sshclient. invoke_shell发送多条命令

import paramiko

import time

ip, port, username, password,command='192.168.1.8',22,'root','123456','date'

ssh = paramiko.SSHClient() #创建一个ssh对象

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) #选择yes，接受key

ssh.connect(hostname=ip, port=port, username=username, password=password,timeout=5) #连接服务器

chan = ssh.invoke_shell() #获取伪终端

chan.send('cd /tmp\r') #发送多个命令

chan.send('ll\r')

time.sleep(1) #需要间隔时间，不然收不到输出

out = chan.recv(1024) #接收命令结果

print(out.decode('utf-8'))

chan.close()

ssh.close() #关闭连接

ssh.open_sftp()建立sftp上传下载文件

import paramiko,os

ip, port, username, password,command='192.168.1.8',22,'root','123456','date'

ssh = paramiko.SSHClient() #创建一个ssh对象

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) #选择yes，接受key

ssh.connect(hostname=ip, port=port, username=username, password=password,timeout=5) #连接服务器

sftp = ssh.open_sftp()

uploadlocalpath = os.path.join(os.getcwd(),'test.txt')

uploadremotepath= '/tmp/test-1.txt'

sftp.put(localpath=uploadlocalpath, remotepath=uploadremotepath)

downloadlocalpath = os.path.join(os.getcwd(),'server-1.txt')

downloadremotepath = '/tmp/server.txt'

sftp.get(remotepath=downloadremotepath, localpath=downloadlocalpath)

sftp.close()

stdin, stdout, stderr = ssh.exec_command('ls /tmp',get_pty=True) #执行一条命令

print(stdout.read().decode('utf-8')) #获取执行命令的结果

ssh.close() #关闭连接
