如何在python socket模块中接收for sendall

import socket

# 创建socket对象
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定IP和端口
host = '127.0.0.1'
port = 12345
s.bind((host, port))

# 监听连接
s.listen(5)

while True:
    # 建立连接
    client_socket, addr = s.accept()
    print('连接地址：', addr)

    # 接收数据
    data = b''
    while True:
        chunk = client_socket.recv(1024)
        if not chunk:
            break
        data += chunk

    # 打印接收到的数据
    print('接收到的数据：', data.decode())

    # 关闭连接
    client_socket.close()
