Python简单HTTP服务(SimpleHTTPServer)和 FTP服务(基于pyftpdlib)

#分享一个很方便的小技巧


一、Python使用SimpleHTTPServer

1.适合环境,在centos、ubuntu等主流发行版都自带Python,在windows下安装也很容易。

2.切到需要通过HTTP交互的目录,输入: python -m SimpleHTTPServer 80 (缺省端口8000)

如果当前文件夹有index.html文件,会默认显示该文件,否则,会以文件列表的形式显示目录下所有文件。

3.脚本方式,由于命令不太好记而且是前台执行,可以使用脚本做成一个服务。

#vi httpserver.py

importSimpleHTTPServer

importSocketServer

PORT =8000

Handler = SimpleHTTPServer.SimpleHTTPRequestHandler

httpd = SocketServer.TCPServer(("", PORT), Handler)

print"serving at port", PORT

httpd.serve_forever()

#python httpserver.py 或  nohup python httpserver.py > /tmp/httpserver.log  2>&1 &

4.在linux下也可以用links ip:端口访问,可以通过http传输文件,对于有n个不同密码不想找的老铁简直是福音。


二、Python使用FTP

1.Python已经有了,还需要下载FTP的库。

#pip install pyftpdlib

2.安装完后,和HTTP服器类似,执行以下执行:

#python -m pyftpdlib -p21 (端口可选,缺省随机,默认是匿名访问,anonymous,密码为空)

3.如果需要自定义ftp策略,则需要修改源码。

from pyftpdlib.authorizers import DummyAuthorizer

from pyftpdlib.handlers import FTPHandler

from pyftpdlib.servers import FTPServer

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 = ('', 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()
