使用python搭建一个简单的FTP服务器

从配置文件获取访问FTP服务器目录的用户名、密码

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

class ConfigReader():
        def __init__(self):
            curpath = os.path.dirname(os.path.realpath(__file__))
            self.config_path = os.path.join(curpath,'config\\config.ini')
            self.cf = ConfigParser()  # 实例化 ConfigParser 对象
            self.ip,self.shared_dir ,self.user_name,self.password = self.read_file()
 
        def get_ip(self):
         return self.ip
        def get_shared_dir(self):
                return self.shared_dir

        def get_user_name_and_psw(self):
            return self.user_name,self.password

        def read_file(self):
                try:
                    print('start read configure file...')
                    self.cf.read(self.config_path,encoding="utf-8-sig")     # 读取文件
                    return self.cf.get('CONFIG','address'),self.cf.get('CONFIG','shared_dir'),self.cf.get('CONFIG','user_name'),self.cf.get('CONFIG','password')
                except Exception as identifier:
                    raise Exception(identifier)

启动服务器

def start_server():
    config = ConfigReader()
    authorizer = DummyAuthorizer()
    user_name,psw = config.get_user_name_and_psw();
    authorizer.add_user(user_name, psw, config.get_shared_dir(), perm='elradfmwMT')
    handler = FTPHandler
    handler.authorizer = authorizer
    handler.banner = "pyftpdlib based ftpd ready."
    address = (config.get_ip(), 21)
    server = FTPServer(address, handler)

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

    # start ftp server
    server.serve_forever()
