python文件上传模块 python如何上传文件

python实现文件上传功能

下面是客户端和服务端实现文件上传功能的程序实现代码，具体实现请写的很详细了，这里我就不废话直接贴代码。欢迎留言优化程序代码！！！

客户端文件上传功能代码

import os
import socket

# 创建客户端socket对象
client_socket = socket.socket()
# IP 和 Port
address = (IP, Port)
# 客户端连接
client_socket.connect(address)
# 文件路径
BASE_DIR = os.path.dirname(os.path.abspath(__file__))

while True:
    msg = input('>>> ').strip()

    cmd, path = msg.split('|')
    # 拼接路劲
    path = os.path.join(BASE_DIR, path)

    filename = os.path.basename(path)
    # 文件大小
    file_size = os.stat(path).st_size
    file_info = 'post|%s|%s' % (filename, file_size)

    client_socket.sendall(bytes(file_info, "utf8"))
    # 打开文件路径，rb字节流模式读取文件
    f = open(path, 'rb')

    has_sent = 0
    while has_sent != file_size:
        data = f.read(1024)
        client_socket.sendall(data)
        has_sent += len(data)

    f.close()
    print("上传成功")
    # if not msg:
    #     continue
    # client_socket.send(msg.encode('utf-8'))
    # data = client_socket.recv(1024)
    # print(data.decode('utf-8'))

# 关闭套接字
client_socket.close()

服务器文件上传功能代码

import socket
import os

# 创建socket对象
server_socket = socket.socket()
# IP 和 Port
address = (IP, Port)
# 绑定IP和Prot
server_socket.bind(address)
server_socket.listen(3)

# 路径
BASE_DIR = os.path.dirname(os.path.abspath(__file__))

while 1:
    conn, addr = server_socket.accept()
    while 1:
        data = conn.recv(1024)
        cmd, filename, filesize = str(data, 'utf8').split('|')
        path = os.path.join(BASE_DIR, 'yuan', filename)
        filesize = int(filesize)

        # 打开文件位置，以'ab'追加模式写入
        f = open(path, 'ab')

        has_recerve = 0
        while has_recerve != filesize:
            data = conn.recv(1024)
            f.write(data)
            has_recerve += len(data)

        f.close()
