在 python3 中通过套接字发送 .mp4 文件

Question

我正在尝试制作两个小程序；一个是从客户端接收 mp4 文件的服务器。客户端只是一个小程序，它发送位于其文件夹中的 .mp4 文件。

我能够完全发送 mp4 文件并创建相同大小的文件，但由于某种原因 mp4 损坏或出现其他问题，我无法在 QuickTime 播放器或 VLC 中播放 mp4 文件。

我不明白这一点，因为我正在复制所有字节，然后全部以小数据包的形式发送。非常感谢一些帮助或提示。

服务器代码：

#!/usr/bin/python3

from socket import socket, gethostname

s = socket()
host = gethostname()
port = 3399
s.bind((host, port))
s.listen(5)
n = 0

while True:
    print("Listening for connections...")
    connection, addr = s.accept()

    try:
        print("Starting to read bytes..")
        buffer = connection.recv(1024)

        with open('video_'+str(n), "wb") as video:
            n += 1
            i = 0
            while buffer:
                buffer = connection.recv(1024)
                video.write(buffer)
                print("buffer {0}".format(i))
                i += 1

        print("Done reading bytes..")
        connection.close()

    except KeyboardInterrupt:
        if connection:
            connection.close()
        break

s.close()

客户端代码：

#!/usr/bin/python3

from socket import socket, gethostname, SHUT_WR

s = socket()
host = gethostname()
port = 3399

s.connect((host, port))

print("Sending video..")

with open("test.mp4", "rb") as video:
    buffer = video.read()
    print(buffer)
    s.sendall(buffer)

print("Done sending..")
s.close()

修复服务器代码中的错误：

#!/usr/bin/python3

from socket import socket, gethostname

s = socket()
host = gethostname()
port = 3399
s.bind((host, port))
s.listen(5)
n = 0

while True:
    print("Listening for connections...")
    connection, addr = s.accept()

    try:
        print("Starting to read bytes..")
        buffer = connection.recv(1024)

        with open('video_'+str(n)+'.mp4', "wb") as video:
            n += 1
            i = 0
            while buffer:                
                video.write(buffer)
                print("buffer {0}".format(i))
                i += 1
                buffer = connection.recv(1024)

        print("Done reading bytes..")
        connection.close()

    except KeyboardInterrupt:
        if connection:
            connection.close()
        break

s.close()

在这里修复：

with open('video_'+str(n)+'.mp4', "wb") as video:

这里：

while buffer:                
    video.write(buffer)
    print("buffer {0}".format(i))
    i += 1
    buffer = connection.recv(1024)
