我想在linux ftp服务器上下载一个包含所有文件和子文件夹/子文件夹的特定目录...
我发现this代码只适用于linux ftp服务器和linux操作系统,但我的操作系统是windows。我查看了代码,它只是对目录结构进行了克隆,因此将"/"
替换为"\\"
可以完成这项工作。但是我没能使代码工作。
以下是我当前(不工作的代码),我刚刚在相关位置替换了path
path.replace("/", "\\")
:
import sys
import ftplib
import os
from ftplib import FTP
ftp=FTP("ftpserver.com")
ftp.login('user', 'pass')
def downloadFiles(path,destination):
#path & destination are str of the form "/dir/folder/something/"
#path should be the abs path to the root FOLDER of the file tree to download
try:
ftp.cwd(path)
#clone path to destination
os.chdir(destination)
print destination[0:len(destination)-1]+path.replace("/", "\\")
os.mkdir(destination[0:len(destination)-1]+path.replace("/", "\\"))
print destination[0:len(destination)-1]+path.replace("/", "\\")+" built"
except OSError:
#folder already exists at destination
pass
except ftplib.error_perm:
#invalid entry (ensure input form: "/dir/folder/something/")
print "error: could not change to "+path
sys.exit("ending session")
#list children:
filelist=ftp.nlst()
for file in filelist:
try:
#this will check if file is folder:
ftp.cwd(path+file+"/")
#if so, explore it:
downloadFiles(path+file+"/",destination)
except ftplib.error_perm:
#not a folder with accessible content
#download & return
os.chdir(destination[0:len(destination)-1]+path.replace("/", "\\"))
#possibly need a permission exception catch:
ftp.retrbinary("RETR "+file, open(os.path.join(destination,file),"wb").write)
print file + " downloaded"
return
downloadFiles("/x/test/download/this/",os.path.dirname(os.path.abspath(__file__))+"\\")
输出:
Traceback (most recent call last):
File "ftpdownload2.py", line 44, in <module>
downloadFiles("/x/test/download/this/",os.path.dirname(os.path.abspath(__file__))+"\\")
File "ftpdownload2.py", line 38, in downloadFiles
os.chdir(destination[0:len(destination)-1]+path.replace("/", "\\"))
WindowsError: [Error 3] The system cannot find the path specified: 'C:\\
Users\\Me\\Desktop\\py_destination_folder\\x\\test\\download\\this\\'
任何人都可以帮我解决这个问题吗?感谢。

目录创建似乎与此问题相似,除了由于Windows格式而发生的更改之外,该问题已被提出。
mkdir -p functionality in Python
How to run os.mkdir() with -p option in Python?
因此,我建议在接受这些问题的答案中显示mkdir_p函数,然后查看窗口是否会创建适当的路径
os.mkdir(destination[0:len(destination)-1]+path.replace("/", "\\"))
然后变成
newpath = destination[0:len(destination)-1]+path.replace("/", "\\")
mkdir_p(newpath)
这使用os.makedirs(path)方法来获取完整路径。你也可以用os.makedirs()
替换os.mkdir()请注意,如果在多个位置使用替换路径,则只需继续使用newpath变量。在其余的代码中,这可能会更容易。
