Python搭建FTP服務(wù)器的方法示例

import os 
from pyftpdlib.authorizers import DummyAuthorizer 
from pyftpdlib.handlers import FTPHandler 
from pyftpdlib.servers import FTPServer 
 
def main(): 
  # 實例化用戶授權(quán)管理 
  authorizer = DummyAuthorizer() 
  authorizer.add_user('user', '12345', 'path', perm='elradfmwMT')#添加用戶 參數(shù):username,password,允許的路徑,權(quán)限 
  authorizer.add_anonymous(os.getcwd())#這里是允許匿名用戶,如果不允許刪掉此行即可 
 
  # 實例化FTPHandler 
  handler = FTPHandler 
  handler.authorizer = authorizer 
 
  # 設(shè)定一個客戶端鏈接時的標(biāo)語 
  handler.banner = "pyftpdlib based ftpd ready." 
 
  #handler.masquerade_address = '151.25.42.11'#指定偽裝ip地址 
  #handler.passive_ports = range(60000, 65535)#指定允許的端口范圍 
 
  address = (ipaddr, 21)#FTP一般使用21,20端口 
  server = FTPServer(address, handler)#FTP服務(wù)器實例 
 
  # set a limit for connections 
  server.max_cons = 256 
  server.max_cons_per_ip = 5 
 
  # 開啟服務(wù)器 
  server.serve_forever() 
 
if __name__ == '__main__': 
  main() 

from ftplib import FTP 
ftp=FTP() 
ftp.connect('localhost',21)#localhost改成服務(wù)器ip地址 
ftp.login(user='user',passwd='12345') 
 
file=open('f://ftpdownload/test.txt','wb') 
ftp.retrbinary("RETR test.txt",file.write,1024)#從服務(wù)器上下載文件 1024字節(jié)一個塊 
ftp.set_debuglevel(0) 
ftp.close()

    os.remove(file)
