Python 使用proto 发送socket数据

import socket
import binascii
import struct
from SensingMonitoring_pb2 import Command, CommandNames

if __name__ == "__main__":
    client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    client.connect(("192.168.1.100", 22295))

    # 发送数据
    command = Command()
    command.COMMANDID = 45678
    command.COMMANDNAME = CommandNames.Value('AuthentcationRequest')
    command.AuthentcationRequest.VERSION = '1.0'
    command.AuthentcationRequest.DWBH = 'xxxxxxxxxx'
    command.AuthentcationRequest.LWRZBH = 'xxxxxxxxxxxxxxxxx'
    message = command.SerializeToString()

    # 包体长度，先打包为字节符 再转16进制
    lenght = struct.pack('<I', len(message)).hex()

    # 包体
    message = binascii.hexlify(message).decode()

    # 包头， 打包为一个 4 字节的小端字节序的字节串。这里的 '<I' 是格式字符串，其中 < 表示小端字节序，I 表示一个无符号整数，占用 4 个字节，将字节串转换为其十六进制
    head = struct.pack('<I', 58250).hex()

    client.send(bytes.fromhex(head + lenght + message))

    # 接收响应数据
    data = client.recv(1024)
    data = binascii.hexlify(data).decode()

    # 包头
    head = bytes.fromhex(data[:8])
    head = struct.unpack('<I', head)[0]

    # 包体长度
    length = bytes.fromhex(data[8:16])
    length = struct.unpack('<I', length)[0]

    # 包体,十六进制字符串转换为对应的字节串
    body = bytes.fromhex(data[16:])
    result = {
        "Flag": head,
        "BodySize": length,
        "Body": body
    }

    command = Command()
    command.ParseFromString(body)
    print(command)
    print(command.AuthentcationResponse.INFO)
    
    client.close()
