助手系列之python的FTP服务器

电脑的OS是Win7,Python版本是2.7.9,安装了pip

因为python没有内置可用的FTP SERVER,所以先选一个第三方的组件安装上,这里我选的是pyftpdlib

pip install pyftpdlib

安装完后可以直接用下面命令启用ftp服务器

python –m pyftpdlib –p 21

但这个ftp服务器没什么安全性,所以我们自己定制一个新的

from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.handlers import FTPHandler
from pyftpdlib.servers import FTPServer
import os

def main():
    # Instantiate a dummy authorizer for managing 'virtual' users
    authorizer = DummyAuthorizer()

    # Define a new user having full r/w permissions and a read-only
    # anonymous user
    authorizer.add_user('user', '12345', '.', perm='elradfmwM')
    authorizer.add_anonymous(os.getcwd())

    # Instantiate FTP handler class
    handler = FTPHandler
    handler.authorizer = authorizer

    # Define a customized banner (string returned when client connects)
    handler.banner = "pyftpdlib based ftpd ready."

    # Specify a masquerade address and the range of ports to use for
    # passive connections.  Decomment in case you're behind a NAT.
    #handler.masquerade_address = '151.25.42.11'
    #handler.passive_ports = range(60000, 65535)

    # Instantiate FTP server class and listen on 0.0.0.0:2121
    address = ('192.168.1.205', 2121)
    server = FTPServer(address, handler)

    # set a limit for connections
    server.max_cons = 256
    server.max_cons_per_ip = 5

    # start ftp server
    server.serve_forever()

if __name__ == '__main__':
    main()

这样我们就可以了用ftp客户端连接192.168.1.205的2121端口了
