This is an article that was created 860 days ago, and the information may have evolved or changed.

  • 针对上一版的脚本进行改进
  • 增加嵌套一层 ‘ Try……finally: ’ ，代码执行末尾提示 “按任意键退出”
  • 修改代码中预定义的登陆账号密码为 input 和 getpass 手动输入
  • 修改文件当前目录为代码自动获取 os.getcwd()
  • 修改执行完成后显示 “A log file is available in……” 记录log路径
  • 想改多线程，threading 模块逻辑没搞清楚

两个脚本
