Question

我在使用pysftp复制文件时遇到问题。这最初是一个有效的WinSCP脚本。我可以使用winscp.com和filezilla中下面脚本中提供的凭据手动复制文件。我已经验证了凭据是正确的，并且存在远程和本地路径。该文件看起来像是复制（我可以看到本地目录中的文件），但它是空的。以下是错误。从其他主机连接和下载文件时，相同的脚本可以正常工作。

这是我的代码：

import pysftp
from datetime import date
from datetime import timedelta

lpath = 'C:/local/path/in/'
rpath = '/remote/path/out/'
yymd = (date.today() - timedelta(days=1)).strftime('%Y%m%d')

with pysftp.Connection('host', username='u', password='p') as sftp:
    with sftp.cd():
        sftp.chdir(rpath)
        for item in sftp.listdir():
            if yymd + '.txt' in item:
                sftp.get(rpath + item, lpath + item, preserve_mtime=True)

Answer 1

为什么不试试getfo(remotepath, flo, callback=None)：

sftp.getfo (rpath + item, open(lpath + item, 'wb'))
