在下面的代码中,第一个测试通过,而第二个测试没有通过,我觉得这很令人费解。
import paramiko
def test1():
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect('10.0.0.107', username='test', password='test')
sftp = client.open_sftp()
sftp.stat('/tmp')
sftp.close()
def get_sftp():
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect('10.0.0.107', username='test', password='test')
return client.open_sftp()
def test2():
sftp = get_sftp()
sftp.stat('/tmp')
sftp.close()
if __name__ == '__main__':
test1()
print 'test1 done'
test2()
print 'test2 done'
这是我得到的:
$ ./script.py
test1 done
Traceback (most recent call last):
File "./play.py", line 25, in <module>

File "./play.py", line 20, in test2
sftp.stat('/tmp')

EOFError
在Ubuntu(Python 2.6 和paramiko 1.7.6 )和Debian(Python 2.7 和paramiko 1.7)上都会发生这种情况。 7 )。
如果我先运行test2
,我只会得到堆栈跟踪,这意味着test2
确实失败了。
答案 0 :(得分:4)
好的,我已经在debian / python2.6 / paramiko1.7.6上验证了它。
原因是client
对象超出get_sftp
范围(并关闭“频道”)。如果您能够将其归还给客户:
import paramiko
def get_sftp():
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect('localhost', username='root', password='B4nan-purr(en)')
return client
def test2():
client = get_sftp()
sftp = client.open_sftp()
sftp.stat('/tmp')
sftp.close()
if __name__ == "__main__":
test2()
然后一切都会起作用(函数名称可能应该更改......)。
