如何使用python 3.2使用scp发送文件? [英] How to send a file using scp using python 3.2?

问题描述

我正尝试通过no-ack的libssh2的python byndings将一组文件发送到远程服务器，但是由于缺少文档，我对库的使用完全迷失了.

I'm trying to send a group of files to a remote server through no-ack's python byndings for libssh2, but I am totally lost regarding the library usage due to the lack of documentation.

我尝试将C文档用于libssh2失败.

I've tried using the C docs for libssh2 unsuccesfully.

由于我使用的是python 3.2，因此paramiko和pexpect都不是问题. 有人可以帮忙吗?

Since I'm using python 3.2, paramiko and pexpect are out of the question. Anyone can help?

我刚刚在no-Ack的博客评论中找到了一些代码.

I just found some code in no-Ack's blog comments to his post.

import libssh2, socket, os

SERVER = 'someserver'
username = 'someuser'
password = 'secret!'

sourceFilePath = 'source/file/path'
destinationFilePath = 'dest/file/path'

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((SERVER, 22))

session = libssh2.Session()
session.startup(sock)

session.userauth_password(username, password)

sourceFile = open(sourceFilePath, 'rb')

channel = session.scp_send(destinationFilePath, 0o644, os.stat(sourceFilePath).st_size)

while True:
    data = sourceFile.read(4096)
    if not data:
        break
    channel.write(data)

exitStatus = channel.exit_status()
channel.close()

似乎可以正常工作.

推荐答案

以下是在Python 3.2中使用libssh2 获取文件的方法. no-Ack向我展示了这一点，这是他的主要荣誉.您需要libssh2的Python3绑定 https://github.com/wallunit/ssh4py

And here's how to get files with libssh2 in Python 3.2. Major kudos to no-Ack for showing me this. You'll need the Python3 bindings for libssh2 https://github.com/wallunit/ssh4py

import libssh2, socket, os

SERVER = 'someserver'
username = 'someuser'
password = 'secret!'

sourceFilePath = 'source/file/path'
destinationFilePath = 'dest/file/path'


sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((SERVER, 22))

session = libssh2.Session()
session.startup(sock)

session.userauth_password(username, password)
(channel, (st_size, _, _, _)) = session.scp_recv(sourceFilePath, True)

destination = open(destinationFilePath, 'wb')

got = 0
while got < st_size:
    data = channel.read(min(st_size - got, 1024))
    got += len(data)
    destination.write(data)

exitStatus = channel.get_exit_status()
channel.close()
