我想用最少的代码行从服务器检索多个日志

Question

我想从Ubuntu服务器(在win 7机器上使用Python 2.7)检索多个日志文件,而不必编写详细的重复代码.我确信我可以使用循环来实现这一目标,但我无法提出任何有效的解决方案(新手程序员).我需要一个比我更有经验的人的指导.在进阶中,我很感激帮助.下面是我在脚本中使用的代码,用于登录服务器并检索一个文件.下面是我想要同时检索的文件的示例路径:

/var/log/apache/a.log /var/log/apache/e.log /var/opt/smart/log/me.log /var/opt/smart/log/se.log

我有更多的路径,但我想你得到了这个想法.以下是用于登录服务器的代码:

def do_siteserver(self, line):
   import paramiko



   paramiko.util.log_to_file('c:\Python27\paramiko-wininst.log')

   host = '10.5.48.65'
   port = 22
   transport = paramiko.Transport((host,port))


   while True:
        try:
           print '\n'
           passW = raw_input("Enter the SiteServer weekly password: ") 
           password = passW
           username = 'gilbert'
           print '\n'
           print 'Establishing SFTP connection to: ', host + ':' + str(port), '...'
           transport.connect(username = username, password = password)
           sftp = paramiko.SFTPClient.from_transport(transport)
           print 'Authorization Successful!!!'

           filepath = '/var/log/apache2/error.log'
           localpath = 'C:\\remote\\NewFile.log'
           sftp.get(filepath, localpath)
           sftp.close()
           transport.close()
           break


        except:
           print '\n'
           print "Authorization Failed!!!"
           break

代替

filepath = '/var/log/apache2/error.log'
localpath = 'C:\\remote\\NewFile.log'
sftp.get(filepath, localpath)

我建议这个:

log_names = {
    "/var/log/apache2/error.log" : 'C:\\remote\\NewFile.log',
    "/var/log/apache/a.log" : 'C:\\remote\\NewFile_a.log',
} # add here all the log files you want to retrieve
for log_file, local_name in log_names.iteritems():
    sftp.get(log_file, local_name)
