Specify file pattern in pysftp get

问题

We can write a simple get like this:

import pysftp

hostname = "somehost"
user = "bob"       
password = "123456"  
filename = 'somefile.txt'

with pysftp.Connection(hostname, username=user, private_key='/home/private_key_file') as sftp:
    sftp.get(filename)

However, I want to specify a pattern in the filename, something like: '*.txt'

Any idea on how to do this using pysftp ?

回答1:

There's no function to download files matching a file mask in pysftp.

You have to:

list the directory, using listdir or walktree (if you need recursion)
iterate the list of files, filtering the files you want
call get individually for each.

For an inspiration, see how get_d or get_r (recursive) are implemented.

For a trivial implementation, see List files on SFTP server matching wildcard in Python using Paramiko. For a recursive example, see Python pysftp get_r from Linux works fine on Linux but not on Windows.

Can confirm after going through the documentation that you can't list using a pattern. So i did something like this:

import pysftp
import re

server = pysftp.Connection(host=FTP_HOST,
                  username=FTP_USERNAME,
                  password=FTP_PASSWORD)
server.cwd(YOUR_FILES_PATH)
filelist = server.listdir()

for filename in filelist:
    filedate = re.search(".*\.txt$", filename)
    if filedate:
        print "FOUND FILE " + filename

import pysftp
import sys

[...]

dn = datetime.now().strftime("%Y%m%d%H");
with pysftp.Connection(myHost, myUsername, password=myPassword) as sftp:
    myFileList = sftp.listdir("files/")
    for filename in myFileList:
        if (filename.rfind("ArrivalList_" + dn) != -1):
            sftp.get("files/" + filename, "/tmp/" + filename)
