python模拟上报消息到rabbitMQ（protobuf）

 

 

1.下载安装protobuf

　　下载地址：https://github.com/protocolbuffers/protobuf/releases

　　下载这两个安装包：protobuf-all-3.6.1.zip和protoc-3.6.1-win32.zip

 

　　解压之后安装：进入python目录

cmd进入该目录安装

安装好之后查看：protoc --version

 

2.编写和转换proto文件

3.用protoc.exe编译proto文件（编译成java语言只要修改--python_out 改成 --java_out）

编写的proto文件存放处

编译生成的py脚本文件

4.根据编写的proto文本，编写python脚本发送SlotMessage消息到rabbitmq

# -*- coding: utf-8 -*-
#!/usr/bin/env python

import binascii
import pika
import datetime
from Simulate import slot_pb2


# rabbitmq 配置信息
MQ_CONFIG = {
    "host": "XXXXXXX",
    "port": XXXXX,
    "vhost": "/",
    "user": "XXXXX",
    "passwd": "XXXXX",
    "exchange": "XXXXX",
}

#发送的指令消息
def message():
    time1 = datetime.datetime.now()  # 获取当前时间
    SlotMessage_auth = slot_pb2.SlotMessage()
    SlotMessage_auth.openId ="XXXXXXX"
    SlotMessage_auth.productId ="XXXXXX"
    SlotMessage_auth.nodeEui = "XXXXXXX"
    SlotMessage_auth.command = slot_pb2.SlotMessage.UPLINK
    SlotMessage_auth.timestamp =str(time1)
    SlotMessage_auth.appMessageType = XXX
    Msg_Payload = SlotMessage_auth.payload
    #发送的指令
    Msg_Payload.data = binascii.a2b_hex("XXXXXXXXX")
    msg = SlotMessage_auth.SerializeToString()
    return msg

#连接rabbitMQ推送消息
def start_publish(message):
    credentials = pika.PlainCredentials(MQ_CONFIG.get("user"), MQ_CONFIG.get("passwd"))
    parameters = pika.ConnectionParameters(MQ_CONFIG.get("host"), MQ_CONFIG.get("port"), MQ_CONFIG.get("vhost"),credentials=credentials)
    connection = pika.BlockingConnection(parameters)
    channel = connection.channel()
    channel.basic_publish(exchange=MQ_CONFIG.get("exchange"), routing_key="", body=message)
    print(" [x] Sent %r" % message)
    connection.close()

if __name__ == '__main__':
    msg= message()
    start_publish(msg)

执行slot_test.py脚本就相当于发送了一条指令消息到rabbitmq
