python-paramiko操作的封装

python-paramiko操作的封装

1. python-paramiko操作的封装

• 案例1、封装密钥paramiko远程使用命令

  #!/usr/bin/env python
  # _*_ coding: utf-8 _*_
  # Author:shichao
  # File: .py
  import paramiko
  
  def remoteExecCommand(ip, port, username, key ,command):
      try:
          # 远程连接 ip和端口
          transport = paramiko.Transport(ip, port)
  
          # 连接私钥
          pkey = paramiko.RSAKey.from_private_key_file(key)
  
          # 连接用户和密码
          transport.connect(username=username, pkey=pkey)
          ssh = paramiko.SSHClient()
          ssh._transport = transport
  
          # stdio 是输入， stdout 是输出，stderr错误输出
          stdio, stdout, stderr = ssh.exec_command(command)
          channel = stdout.channel
          status = channel.recv_exit_status()
  
          # stdout标准输出读取数据
          stdout = stdout.read().decode()
  
          # stderr标准错误数据输出读取数据
          stderr = stderr.read().decode()
  
  
          # 使用return 返回数据
          return {"stdout":stdout , "stderr":stderr, "status":status}
  
      except Exception as e:
          print(e)
  
      finally:
          try:
              ssh.close()
          except Exception as e:
              print(e)
          try:
              ssh.close()
          except Exception as e:
              print(e)
  
  # 进行本地测试
  if __name__ == "__main__":
     result = remoteExecCommand("192.168.0.200", 22, 'root', "/Users/admin/.ssh/id_rsa", "ls /tmp/")
     print(result)
  

• 案例2、封装使用密码paramiko远程使用命令

  #!/usr/bin/env python
  # _*_ coding: utf-8 _*_
  # Author:shichao
  # File: .py
  import paramiko
  
  def remoteExecCommand(ip, port, username, pwd ,command):
      try:
          # 远程连接 ip和端口
          transport = paramiko.Transport(ip, port)
  
          # 连接私钥
          pkey = paramiko.RSAKey.from_private_key_file(pwd)
  
          # 连接用户和密码
          transport.connect(username=username, pkey=pkey)
          ssh = paramiko.SSHClient()
          ssh._transport = transport
  
          # stdio 是输入， stdout 是输出，stderr错误输出
          stdio, stdout, stderr = ssh.exec_command(command)
          channel = stdout.channel
          status = channel.recv_exit_status()
  
          # stdout标准输出读取数据
          stdout = stdout.read().decode()
  
          # stderr标准错误数据输出读取数据
          stderr = stderr.read().decode()
  
  
          # 使用return 返回数据
          return {"stdout":stdout , "stderr":stderr, "status":status}
  
      except Exception as e:
          print(e)
  
      finally:
          try:
              ssh.close()
          except Exception as e:
              print(e)
          try:
              ssh.close()
          except Exception as e:
              print(e)
  
  # 进行本地测试
  if __name__ == "__main__":
     result = remoteExecCommand("192.168.0.200", 22, 'root', "123456", "ls /tmp/")
     print(result)
  

• 案例3、封装paramiko-client远程上传文件

  #!/usr/bin/env python
  # _*_ coding: utf-8 _*_

  # File: .py
  import paramiko
  
  
  def remoteGET(ip, port, username, key, localpath, remotepath,):
      try:

          pkey = paramiko.RSAKey.from_private_key_file(key)
          # 远程连接 ip和端口
          transport = paramiko.Transport(ip, port)
          # 连接用户和密码
          transport.connect(username=username, pkey=pkey)
          # 文件工具
          sftp = paramiko.SFTPClient.from_transport(transport)
  
          # 上传文件 localpath是本地路径，remotepath远程路径
          result = sftp.put(localpath,remotepath)
  
          # 使用return 返回数据
          return result
  
      except Exception as e:
          print(e)
  
      # 关闭连接
      finally:
          try:
              sftp.close()
          except Exception as e:
              print(e)
