所以我正在使用paramiko进行一些基本的SSH测试,而且我没有得到任何输出到stdout。继承我的代码。
import paramiko
client=paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
com="ls ~/desktop"
client.connect('MyIPAddress',MyPortNumber, username='username', password='password')
output=""
stdin, stdout, stderr = client.exec_command(com)
print "ssh succuessful. Closing connection"
client.close()
print "Connection closed"
stdout=stdout.readlines()
print stdout
print com
for line in stdout:
output=output+line
if output!="":
print output
else:
print "There was no output for this command"
所以每当我运行它时,执行命令(如果我执行类似cp的操作,文件被复制),但我总是得到“此命令没有输出”。当打印stdout = stdout.readlines()时,[]是输出。另外,如果我在for循环中添加一个print语句,它就永远不会运行。有人可以帮帮我吗?谢谢!

您在阅读行之前已关闭连接:
import paramiko
client=paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
com="ls ~/desktop"
client.connect('MyIPAddress',MyPortNumber, username='username', password='password')
output=""
stdin, stdout, stderr = client.exec_command(com)
print "ssh succuessful. Closing connection"
stdout=stdout.readlines()
client.close()
print "Connection closed"
print stdout
print com
for line in stdout:
output=output+line
if output!="":
print output
else:
print "There was no output for this command"

正如@jabaldonedo 所说,您在阅读 stdout
之前关闭了 SSHClient 连接。 SSHClient 可以用作上下文管理器。使用 SSHClient 作为上下文管理器有助于防止您在 ssh 连接关闭后尝试访问 stdout
和 stderr
。 Python3 语法中的结果代码如下所示:
from paramiko import AutoAddPolicy, SSHClient
with SSHClient() as client:
client.set_missing_host_key_policy(AutoAddPolicy)
client.connect(
'MyIPAddress',
MyPortNumber,
username='username',
password='password'
)
com = "ls ~/desktop"
stdin, stdout, stderr = client.exec_command(com)
output = ''
for line in stdout.readlines()
output += line
if output:
print(output)
else:
print("There was no output for this command")
