Python搭建FTP服务器的方法示例

import os from pyftpdlib.authorizers import DummyAuthorizer from pyftpdlib.handlers import FTPHandler from pyftpdlib.servers import FTPServer  def main():   # 实例化用户授权管理   authorizer = DummyAuthorizer()   authorizer.add_user('user', '12345', 'path', perm='elradfmwMT')#添加用户 参数:username,password,允许的路径,权限   authorizer.add_anonymous(os.getcwd())#这里是允许匿名用户,如果不允许删掉此行即可    # 实例化FTPHandler   handler = FTPHandler   handler.authorizer = authorizer    # 设定一个客户端链接时的标语   handler.banner = "pyftpdlib based ftpd ready."    #handler.masquerade_address = '151.25.42.11'#指定伪装ip地址   #handler.passive_ports = range(60000, 65535)#指定允许的端口范围    address = (ipaddr, 21)#FTP一般使用21,20端口   server = FTPServer(address, handler)#FTP服务器实例    # set a limit for connections   server.max_cons = 256   server.max_cons_per_ip = 5    # 开启服务器   server.serve_forever()  if __name__ == '__main__':   main() 

from ftplib import FTP ftp=FTP() ftp.connect('localhost',21)#localhost改成服务器ip地址 ftp.login(user='user',passwd='12345')  file=open('f://ftpdownload/test.txt','wb') ftp.retrbinary("RETR test.txt",file.write,1024)#从服务器上下载文件 1024字节一个块 ftp.set_debuglevel(0) ftp.close() 

class MyHandler(FTPHandler):    def on_connect(self):#链接时调用     print "%s:%s connected" % (self.remote_ip, self.remote_port)    def on_disconnect(self):#关闭连接是调用     # do something when client disconnects     pass    def on_login(self, username):#登录时调用     # do something when user login     pass    def on_logout(self, username):#登出时调用     # do something when user logs out     pass    def on_file_sent(self, file):#文件下载后调用     # do something when a file has been sent     pass    def on_file_received(self, file):#文件上传后调用     # do something when a file has been received     pass    def on_incomplete_file_sent(self, file):#下载文件时调用     # do something when a file is partially sent     pass    def on_incomplete_file_received(self, file):#上传文件时调用     # remove partially uploaded files     import os     os.remove(file)
