socket实现FTP

FTP客户端：
这块应该是在数据库里面存储：用户名，密码  这里测试就暂时用一个字典：
jesn@jesn-virtual-machine:~$ cat socket_Client.py
import socket, time
HOST = 'localhost'
PORT = 9999
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
dirc = {'jesn':110, 'mary':120}
def check_user():
        while 1:
                user = raw_input('please enter your user').strip()
                if user in dirc.keys():
                        count = 0
                        while 1:
                                if count <3:
                                        passwd = int(raw_input('please enter your passwd').strip())
                                        if passwd == dirc[user]:
                                                print 'welcome in my ftp!'
                                                break
                                        else:
                                                print 'error passwd!!! please enter again!'
                                                count = count +1
                                                continue
                else:
                        print 'username not in the list!!!'
                        continue
                break
check_user()
while 1:
        Input = raw_input('Please input the command :').strip()
        if len(Input) == 0:
                continue
        s.sendall(Input)
        user_input = Input.split()
        if user_input[0] == 'get':
                with open(user_input[1],'wr') as f:
                        f.write(s.recv(1024))
                        print 'getting ...'
                if s.recv(1024) == 'ftpisdown':continue
                if not s.recv(1024):break
        if user_input[0] == 'set':
                with open(user_input[1],'rb') as f:
                        y = f.read()
                        s.sendall(y)
                        print 'senting...'
                if s.recv(1024) == 'receiveDown':continue
                if not s.recv(1024):break
        data = s.recv(8192)
        time.sleep(2)
        #print 'Received', repr(data)
        print data
s.close()
