Question

请，我在python 2.7中有这些代码，非常适合从服务器下载文件。

>如何使用套接字扩展它们以添加上传，并具有在服务器端列出文件的功能，并且用户应在允许进入和列出文件之前输入硬编码的用户名和密码？

要求很简单，但我仍然是初学者..

服务器代码

    import socket
    import threading
    import os

    def RetrFile(name, sock):
    filename = sock.recv(1024)
    if os.path.isfile(filename):
        sock.send("EXISTS " + str(os.path.getsize(filename)))
        userResponse = sock.recv(1024)
        if userResponse[:2] == 'OK':
            with open(filename, 'rb') as f:
                bytesToSend = f.read(1024)
                sock.send(bytesToSend)
                while bytesToSend != "":
                    bytesToSend = f.read(1024)
                    sock.send(bytesToSend)
    else:
        sock.send("ERR ")

    sock.close()

def Main():
    host = '127.0.0.1'
    port = 5000


    s = socket.socket()
    s.bind((host,port))

    s.listen(5)

    print "Server Started."
    while True:
        c, addr = s.accept()
        print "client connedted ip:<" + str(addr) + ">"
        t = threading.Thread(target=RetrFile, args=("RetrThread", c))
        t.start()

    s.close()

if __name__ == '__main__':
    Main()

客户代码

import socket

def Main():
    host = '127.0.0.1'
    port = 5000

    s = socket.socket()
    s.connect((host, port))

    filename = raw_input("Filename? -> ")
    if filename != 'q':
        s.send(filename)
        data = s.recv(1024)
        if data[:6] == 'EXISTS':
            filesize = long(data[6:])
            message = raw_input("File exists, " + str(filesize) +"Bytes, download? (Y/N)? -> ")
            if message == 'Y':
                s.send("OK")
                f = open('new_'+filename, 'wb')
                data = s.recv(1024)
                totalRecv = len(data)
                f.write(data)
                while totalRecv < filesize:
                    data = s.recv(1024)
                    totalRecv += len(data)
                    f.write(data)
                    print "{0:.2f}".format((totalRecv/float(filesize))*100)+ "% Done"
                print "Download Complete!"
                f.close()
        else:
            print "File Does Not Exist!"

    s.close()


if __name__ == '__main__':
    Main()
