Python 3.7.3，请问如何往FTP上传指定位置的一整个文件夹？

mchl.gao

例如文件夹在C盘根目录下，名字是1，里面有不同格式的文件，但是再没有子文件夹了。要上传到FTP目录中的guest文件夹，guest的文件夹位置是/home/www/guest，权限是drwx-xr-x。我用别的FTP软件访问FTP，连接和上传下载都没有任何问题。

我开始的时候象下面这样写。

1. 
   
2. 
   
3. import ftplib
   
4. 
   
5. def ftpconnect():
   
6.     ftp_server = '192.168.1.21'
   
7.     username = '1234567'
   
8.     password = '123456789'
   
9.     timeout = 30
   
10.     port = 21
    
11. 
    
12. ftp = ftplib.FTP()
    
13. ftp.set_debuglevel(2)
    
14. 
    
15. def uploadfile_to_FTP():
    
16.     ftp = ftpconnect()
    
17. 
    
18. bufsize = 1024
    
19. for filename in os.listdir(r"C:/1/"):
    
20.     remotepath = "/home/www/guest"+filename
    
21.     localpath = "C:/1/"+filename
    
22.     fp = open(localpath, 'rb')
    
23.     ftp.storbinary('STOR ' + remotepath, fp, bufsize)
    
24. 
    
25. ftp.set_debuglevel(0)
    
26. fp.close()
    
27. ftp.quit()
    
28. 
    

复制代码

运行后无法开始上传，报错提示如下：
=================== RESTART: H:\my software\ftpbackup\test.py ===================
Traceback (most recent call last):
  File "H:/my software/ftpbackup/test.py", line 19, in <module>
    for filename in os.listdir(r"C:/1/"):
NameError: name 'os' is not defined
>>>

我以为是没有添加OS，然后把代码改成下面这样：

1. 
   
2. 
   
3. import os
   
4. import ftplib
   
5. 
   
6. 
   
7. def ftpconnect():
   
8.     ftp_server = '192.168.1.21'
   
9.     username = '1234567'
   
10.     password = '123456789'
    
11.     timeout = 30
    
12.     port = 21
    
13. 
    
14. ftp = ftplib.FTP()
    
15. ftp.set_debuglevel(2)
    
16. 
    
17. def uploadfile_to_FTP():
    
18.     ftp = ftpconnect()
    
19. 
    
20. bufsize = 1024
    
21. for filename in os.listdir(r"C:/1/"):
    
22.     remotepath = "/home/www/guest"+filename
    
23.     localpath = "C:/1/"+filename
    
24.     fp = open(localpath, 'rb')
    
25.     ftp.storbinary('STOR ' + remotepath, fp, bufsize)
    
26. 
    
27. ftp.set_debuglevel(0)
    
28. fp.close()
    
29. ftp.quit()
    
30. 
    

复制代码

运行后还是无法开始上传，报错如下：

*put* 'TYPE I\r\n'

请各位高手指教一下，到底是哪里出了问题。谢谢

ftp传输文件不是直接发送文件都行了，你为什么要读取文件呢？
你发的代码的第二个版本的第24行，你把文件读取出来意义何在？

ps：我不知道ftplib模块怎么用

谢谢提醒，我去掉了读文件的功能，可是还是不行。错误提示如下：

Traceback (most recent call last):
  File "H:/ms/ftpbackup/422.py", line 24, in <module>
    ftp.quit()
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python37-32\lib\ftplib.py", line 665, in quit
    resp = self.voidcmd('QUIT')
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python37-32\lib\ftplib.py", line 277, in voidcmd
    self.putcmd(cmd)
