2、根据新的excel密码文件,更新服务器密码,将更新后的结果保存到另外一个excel文件。
a、原始excel文件字段格式,最后一个字段为原始密码
IP USER PORT pwd
b、生成新的密码文件字段格式,最后一个字段为更新密码
IP USER PORT pwd pwd20180929
c、生成新的密码文件字段格式,最后一个字段为更新是否成功的标识
IP PORT USERNAME OLDPASS NEWPASS FLAG
按照面向对象编程的思想,可以设计2个类,excelhandler和ChangePassword
excelhandler主要负责excel文件的读取,写入,增加一个生成密码文件
ChangePassword主要利用paramiko登陆服务器进行密码更新
excelhandler类

ChangePassword类

main
#_*_ coding: utf-8 _*_ ''' @author liaogs ''' import re import sys from excelhandler import excelhandler from changepassword import ChangePassword if __name__ == '__main__': if len(sys.argv) == 1: eh = excelhandler("pass.xlsx") else: eh = excelhandler(sys.argv[1]) eh.read_excel() def updatepassword(): ret = eh.get_server_list() tasklist = [] for i in range(len(ret)): print(ret[i][0],ret[i][2],ret[i][1],ret[i][3],ret[i][4]) cp = ChangePassword(hostip=ret[i][0],port=int(ret[i][2]),username=ret[i][1],oldpass=ret[i][3],newpass=ret[i][4]) task = cp.run_change() tasklist.append(task) print(tasklist) eh.write_excel(tasklist) while True: inp = input("1、生成密码 2、更新密码>>") if str(inp) == "1": eh.gen_new_password_excel() elif str(inp) == "2": updatepassword() elif inp == "exit": exit() else: continue
