ftplib文件选择 [英] ftplib file select
本文介绍了ftplib文件选择的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
使用手册说明
要下载文件,请使用ftp.retrlines('RETR'+文件名)
To download a file, use ftp.retrlines('RETR ' + filename)
这是我做的:
Here is what i do:
ftp.retrbinary('RETR media/backups/andrey.txt', open("file_to_get.txt", 'a+').write)
可否请某人建议如何在RETR命令后面添加通过raw_input添加的文件名变量?
使用%s但这不起作用,它会像文件名的一部分那样处理。
Could please someone advise how to put filename variable, previously added via raw_input, after the "RETR" command? Used %s but this does not work, it gets processed like a part of a filename.
ftp.retrbinary('RETR %s', open("file_to_get.txt", 'a+').write) %raw_input("print file name")
产生这样的结果:
produces this:
c:\>python ftp_client.py
Enter host95.31.8.52
drwxrwxrwx 61 99 102 32768 Sep 14 01:39 backpl

rint file name")
File "C:\Python27\lib\ftplib.py", line 399, in retrbinary
conn = self.transfercmd(cmd, rest)
File "C:\Python27\lib\ftplib.py", line 361, in transfercmd
return self.ntransfercmd(cmd, rest)[0]
File "C:\Python27\lib\ftplib.py", line 330, in ntransfercmd
resp = self.sendcmd(cmd)
File "C:\Python27\lib\ftplib.py", line 244, in sendcmd
return self.getresp()
File "C:\Python27\lib\ftplib.py", line 219, in getresp
raise error_perm, resp
ftplib.error_perm: 550 Can't open %s: No such file or directory
c:\>
推荐答案
filename = 'andrey.txt'
path = "media/backups/"
ftp.cwd(path)
ftp.retrbinary("RETR " + filename ,open(filename, 'a+').write)
