py学习之FTP

1.FTP之参数解析与命令分发

a) 层级目录如下

b) 配置文件如下

#!/usr/bin/env python
# -*- coding:utf8 -*-

import socket
sk=socket.socket()
sk.connect(('127.0.0.1',8080))#括号里是元组

ftp_client.py

#!/usr/bin/env python
# -*- coding:utf8 -*-
import os,sys
PATH=os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(PATH)
# print(os.path.dirname(__file__)) #打印文件所在当前目录
# print(os.path.abspath(__file__))#定位到文件绝对路径
from core import main

if __name__ == '__main__':
    main.ArgvHandler()

ftp_server.py

#!/usr/bin/env python
# -*- coding:utf8 -*-

IP='127.0.0.1'

PORT=8080

settings.py

#!/usr/bin/env python
# -*- coding:utf8 -*-

import optparse   #解析命令行的命令
import socketserver

from conf import settings

from core import server  #必须这样导入，因为path路径找不到

class ArgvHandler():
    def __init__(self): #初始方法
        self.op=optparse.OptionParser()
        # self.op.add_option("-s","--s",dest="server")   # -s 自己起的,--s 固定参数
        # self.op.add_option("-P","--port",dest="port")

        options,args=self.op.parse_args()  #参数解析，返回两个结果,option是绑定参数，
                                           # args返回没绑定的参数列表
        self.verify_args(options,args)

    def verify_args(self,options,args):
        cmd = args[0]
        if hasattr(self,cmd):  #反射
            func=getattr(self,cmd) #拿到对应
            func()

    def start(self):
        print('The server is working on port 8080......')
        s=socketserver.ThreadingTCPServer((settings.IP,settings.PORT),server.Serverhandler)
        s.serve_forever()

    def help(self):

        print(type(options))
        print(options.server)
