Question

我正在开发一个应用程序，其中以python编码的kivy gui窗口在按下download时创建了一个套接字，并从服务器下载了视频文件。但是，下载的视频在gui窗口关闭或最小化之前不会显示在资源管理器中。视频也似乎没有注意到新的视频文件已添加，导致它没有显示此类文件错误。如何解决呢？ ps：这两个文件和一个示例视频文件是在Pycharm中执行的由于服务器和客户端位于同一目录中，因此附加了“ new”的视频文件将出现在项目文件中。

这是server.py：

import socket import threading import os


def RetrFile(name, sock):
    filename = sock.recv(1024)
    filename = filename.decode('utf-8')
    if os.path.isfile(filename):
        sock.send(str.encode('EXISTS') + str(os.path.getsize(filename)).encode('utf-8'))
        userResponse = sock.recv(1024)
        userResponse = userResponse.decode('utf-8')
        if userResponse[:2] == 'OK':
            with open(filename, 'rb') as f:
                bytesToSend = f.read(1024)
                sock.send(bytesToSend)
                while bytesToSend != "0":
                    bytesToSend = f.read(1024)
                    sock.send(bytesToSend)
    else:
        sock.send(str.encode("ERR "))

    sock.close()


def Main():
    host = 'enter your ipv4 address found by typing ipconfig in cmd'
    port = 5000

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

    s.listen(5)

    print("Server Started.\nWaiting for a connection...")
    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()

这是客户端和基维gui代码：

import socket

def Main():
host = 'enter your ipv4 address found by typing ipconfig in cmd'
port = 5000


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

filename = "new_finalvideo.avi"
if filename != 'q':
    s.send(filename.encode('utf-8'))
    data = s.recv(1024)
    data = data.decode('utf-8')
    if data[:6] == 'EXISTS':
        filesize = int(data[6:])
        print("File exists, " + str(filesize) + " bytes, downloading-> ")
        if (True):
            s.send(str.encode("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()
