# 一 、django中启动ftp服务 #

#ftpServer.py
    import os
    from pyftpdlib.authorizers import DummyAuthorizer
    from pyftpdlib.handlers import FTPHandler
    from pyftpdlib.servers import FTPServer, MultiprocessFTPServer, ThreadedFTPServer
    from django.core.management import BaseCommand
    
    class Command(BaseCommand):
        def handle(self, *args, **options):
            """
            实现主要逻辑,启动ftp服务
            :param args:
            :param options:
            :return:
            """
            authorizer = DummyAuthorizer()
            handler = MyHandler
            handler.authorizer = authorizer
            ftp_server(authorizer)
            # server = FTPServer(("0.0.0.0", 2121), handler)
            # server = MultiprocessFTPServer(("0.0.0.0", 2121), handler)
            server = ThreadedFTPServer((FTP_IP, FTP_POST), handler)
            server.serve_forever()

### 1.文件存放路径：apps/<app>/management/commands/ftpServer.py ###

### 2.启动ftp服务命令：python manage.py ftpServer ###

# **二、接下来实现动态添加ftp用户的功能** #

user_cfg_path = os.path.join(BASE_DIR + '/apps/ftpUser.cfg')
    class MyHandler(FTPHandler):
        """
        回调方法
        """
        def on_connect(self):  # 链接时调用
            ftp_server(self.authorizer)
            print("%s:%s connected" % (self.remote_ip, self.remote_port))
    
    
    def get_user(userfile):
        # 定义一个用户列表
        user_list = []
        with open(userfile) as f:
            for line in f:
                if not line.startswith('#') and line:
                    if len(line.split()) == 6:
                        # print(line.split())
                        user_list.append(line.split())
                    else:
                        print("user.conf配置错误")
        return user_list
    
    
    def ftp_server(authorizer):
        # 添加用户权限和路径，括号内的参数是(用户名， 密码， 用户目录， 权限)
        # authorizer.add_user('user', '12345', '/home/', perm='elradfmw')
        user_list = get_user(user_cfg_path)
        for user in user_list:
            name, passwd, permit, homedir, date, time = user
            try:
                authorizer.add_user(name, passwd, homedir, perm=permit)
            except Exception as e:
                print(e)
    
    class Command(BaseCommand):
        def handle(self, *args, **options):
            """
            实现主要逻辑,启动ftp服务
            :param args:
            :param options:
            :return:
            """
            authorizer = DummyAuthorizer()
            handler = MyHandler
            handler.authorizer = authorizer
            ftp_server(authorizer)
            # server = FTPServer(("0.0.0.0", 2121), handler)
            # server = MultiprocessFTPServer(("0.0.0.0", 2121), handler)
            server = ThreadedFTPServer((FTP_IP, FTP_POST), handler)
            server.serve_forever()

实现原理：每当用户连接ftp服务端的时候，就会调用回调方法，重新读取存储用户的配置文件，实现动态

至于动态添加用户，就需要，操作这个存储用户信息的配置文件了

# 三、操作这个存储用户信息的配置文件 #

1.贴一下我的配置文件 ：用户名     密码     操作权限(只有下载)    访问文件的路径      添加用户的时间

#ftpUser.cfg
    7@7.com  SNFSTP  elr  /Users/cagey/gitlib_projects/test/PTM_backend/upload/files/7@7.com  2019-08-01 17:49:03.727385
    1@1.com  P4X4R1  elr  /Users/cagey/gitlib_projects/test/PTM_backend/upload/files/1@1.com  2019-08-01 17:48:40
    2@2.com  PYUVTN  elr  /Users/cagey/gitlib_projects/test/PTM_backend/upload/files/  2019-07-26 16:52:45
    cagey7@163.com  BB1IVP  elr  /Users/cagey/gitlib_projects/test/PTM_backend/upload/files/  2019-07-26 16:05:48
    admin  123  elradfmwMT  /Users/cagey/gitlib_projects/test/PTM_backend/upload/files/  2019-07-26 15:54:00

2.具体的方法

def get_ftp_user(username):
        """
        获取用户ftp配置信息
        :param username: cagey7@163.com
        :return: ['cagey7@163.com', 'JG14CD', 'elr', '/Users/cagey/gitlib_projects/tool/new/PTM_backend/upload/files/']
        """
        name = username
        with open(user_cfg_path) as f:
            for line in f:
                if line.startswith(name):
                    if len(line.split()) == 6:
                        return line.split()
                    else:
                        return "user.conf配置错误!"
            return None
    
    
    def del_ftp_user(username):
        """
        删除ftp用户
        :param username:
        :return:
        """
        with open(user_cfg_path, 'r') as r:
            lines = r.readlines()
        with open(user_cfg_path, 'w') as w:
            for l in lines:
                if not l.startswith(username):
                    w.write(l)
    
    
    def add_ftp_user(user_info):
        """
        添加,更新ftp用户
        :param user_info:
        :return:
        """
        with open(user_cfg_path, 'r') as fp:
            lines = []
            for line in fp:
                lines.append(line)
        with open(user_cfg_path, 'w') as fp:
            lines.insert(0, str(user_info) + '\n')  # 在第一行插入
            s = ''.join(lines)
            fp.write(s)
    
    def random_code():
        # 生成随机6位随机数含字母
        code = []
        for i in range(6):
            if i == random.randint(1, 5):
                code.append(str(random.randint(1, 5)))
            else:
                code.append(chr(random.randint(65, 90)))
        return ''.join(code)

### 其他的功能可以根据自己的具体业务需求实现，详细的pyftpdlib配置我就不介绍了，网上很多     ###
