Python 使用proto 发送socket数据

import socket
import binascii
import struct
from SensingMonitoring_pb2 import Command, CommandNamesif __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 = 45678command.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()
