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 DummyAuthorizerfrom pyftpdlib.handlers import FTPHandlerfrom pyftpdlib.servers import FTPServerimport 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
