Python tcp文件传输

TCP协议是一种可靠的传输协议，适合用于文件传输。下面是一个简单的 Python TCP 文件传输的代码示例：

服务端代码：

import socket

HOST = '127.0.0.1'
PORT = 8888

def main():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind((HOST, PORT))
    s.listen(1)
    print('Waiting for client connection...')
    conn, addr = s.accept()
    print(f'Connected by {addr}')

    with open('received_file.txt', 'wb') as f:
        while True:
            data = conn.recv(1024)
            if not data:
                break
            f.write(data)

    print('File transfer completed')
    conn.close()

if __name__ == '__main__':
    main()

客户端代码：

import socket

HOST = '127.0.0.1'
PORT = 8888

def main():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((HOST, PORT))

    with open('file_to_send.txt', 'rb') as f:
        while True:
            data = f.read(1024)
            if not data:
                break
            s.sendall(data)

    print('File transfer completed')
    s.close()

if __name__ == '__main__':
    main()

在这个例子中，客户端将本地的 `file_to_send.txt` 文件发送给服务端，服务端接收文件并保存到本地的 `received_file.txt` 文件中。你可以根据自己的需求修改代码，比如修改文件名、路径等等。
