問(wèn)題描述

我必須使用 Python 腳本自動(dòng)將文件夾上傳到 FTP.我可以上傳單個(gè)文件，但不能上傳帶有子文件夾和文件的文件夾.我做了很多搜索，但失敗了.有人可以幫我嗎?提前致謝.

I have to automatically upload folders to an FTP using a Python script. I am able to upload a single file, but not folders with subfolders and files in them. I did a lot of search, but failed. Could some one help me out here? Thanks in advance.

#! /usr/bin/python

import ftplib
s = ftplib.FTP('serverip','usrname','password') 
file = '/home/rock/test.txt'
ftppath = '/IT'
filename = "rak"
s.cwd(ftppath)
f = open(file,'rb')                
s.storbinary('STOR ' + filename, f)         

f.close()                                
s.quit()

你基本上需要使用 os.walk() 來(lái)抓取這些文件并傳輸它們.

You basically need to use os.walk() to grab those files and transfer them.

這是我為自己編寫(xiě)的腳本，用于滿足您的大部分要求.我很久以前寫(xiě)的，所以如果我再寫(xiě)一次，我可能會(huì)做不同的事情，但我從中得到了很多用處.

Here's a script I wrote for myself to do much of what your asking. I wrote it a long time ago, so I'd probably do it differently if I wrote it again, but I get a lot of use out of it.

它導(dǎo)入 psftplib，這是我為 putty sftp 編寫(xiě)的包裝器.隨意刪除這些引用，或在以下位置獲取庫(kù):http://code.google.com/p/psftplib/source/browse/trunk/psftplib.py

It imports psftplib, which is a wrapper I wrote for the putty sftp. Feel free to remove these references, or grab the lib at: http://code.google.com/p/psftplib/source/browse/trunk/psftplib.py
