python下paramiko模块学习之四：从远程主机批量下载文件到本机

前面我们已经学习了paramiko的上传功能，这里就要给大家介绍下他的下载功能，呵呵，不废话了，直接上代码，感兴趣的可以研究下：

[root@centos6 python]# cat paramiko-download.py
#!/usr/bin/env python
import paramiko
import os
import datetime
hostname='74.63.229.*'
username='root'
password='abc123'
port=22
local_dir='/tmp/'
remote_dir='/tmp/test/'
if __name__=="__main__":
#    try:
t=paramiko.Transport((hostname,port))
t.connect(username=username,password=password)
sftp=paramiko.SFTPClient.from_transport(t)
#        files=sftp.listdir(dir_path)
files=sftp.listdir(remote_dir)
for f in files:
print ''
print '#########################################'
print 'Beginning to download file  from %s  %s ' % (hostname,datetime.datetime.now())
print 'Downloading file:',os.path.join(remote_dir,f)

sftp.get(os.path.join(remote_dir,f),os.path.join(local_dir,f))
# sftp.put(os.path.join(local_dir,f),os.path.join(remote_dir,f))

print 'Download file success %s ' % datetime.datetime.now()
print ''
print '##########################################'

#except Exception:
#       print "error!"
t.close()

[root@centos6 python]#

呵呵，代码和前面上传功能稍有区别，这里就不写注释了，我的变量名都是和直观的就能让你明白意思了，哈哈，下面看下演示功能吧，看下效果：

[root@centos6 python]# clear
[root@centos6 python]# python paramiko-download.py

呵呵，效果还是不错的，至此，paramiko的上传下载都已经介绍完 了，呵呵，下面讲虾米内容呢，千万别走开，精彩内容继续为你放松，下一次，我将为你介绍和前面讲过的，读取配置文件，上传批量文件到多部服务器，敬请关注。。。
