ONE NET MQTT+HTTP多端控制

使用移动的ONENET实现数据上传与远程控制，数据上传使用MQTT协议（ESP8266），而数据查看和远程控制使用的HTTP（安卓端/QT），效果：

ONENET简单MQTT和HTTP使用

ESP8266通过MQTT上传和订阅数据我就不多赘述了，教程很多，我直接刷的MQTT固件，然后通过AT指令进行MQTT操作的

cpp 复制代码

void esp_init(){
	SendCmd(ATE0,"OK",10);	//关闭回显
	HAL_Delay(50);
	SendCmd(AT,"OK",10);//发送AT指令
	HAL_Delay(50);
	
	SendCmd(CWJAP1,"IP",40);//连接WIFI，CWJAP1为连接的WiFi信息
	HAL_Delay(50);
	SendCmd(MQTTUSERCFG,"OK",10);//设置MQTT信息
	HAL_Delay(100);
	SendCmd(MQTTCONN,"OK",40);//连接MQTT
	HAL_Delay(100);
	SendCmd(MQTTSUB,"OK",40);//订阅MQTT
	HAL_Delay(100);
}

cpp 复制代码

#define   AT          "AT\r\n"	
#define   ATE0        "ATE0\r\n"	
#define   CWMODE      "AT+CWMODE=1\r\n"
#define   RST         "AT+RST\r\n"
#define   CIFSR       "AT+CIFSR\r\n"

#define   CWJAP       "AT+CWJAP=\"Caneve16spro\",\"123456789\"\r\n"//网络连接信息
#define   CWJAP1       "AT+CWJAP=\"CanEve17Pro\",\"12345678\"\r\n"

#define		MQTTUSERCFG "AT+MQTTUSERCFG=0,1,\"FARM\",\"xxxxx\",\"version=2018-10-31&res=xxxxx\",0,0,\"\"\r\n" //这个就是MQTT的配置信息，根据自己的填
#define   MQTTCONN    "AT+MQTTCONN=0,\"mqtts.heclouds.com\",1883,0\r\n"//MQTT服务器
#define   MQTTSUB			"AT+MQTTSUB=0,\"$sys/xxxxx/FARM/thing/property/set\",1\r\n"//MQTT订阅

#define   CIPSTART    "AT+CIPSTART=\"TCP\",\"192.168.31.112\",20233\r\n"
#define   CIPMODE     "AT+CIPMODE=1\r\n"

上传数据

cpp 复制代码

void pub_dat(){//MQTT发布更新数据
	memset(pub_dat_buf,0,sizeof pub_dat_buf);//清空发送数组
	memset(topic,0,sizeof topic);
	sprintf(pub_dat_buf,"{\"id\": \"123\",\"params\": {\"FAN\": {\"value\": %d},\"TEMP\": { \"value\": %.1f},\"LIGHT\": {\"value\": %d},\"LED\": {\"value\": %d},\"HUM\": {\"value\": %.0f},\"SOIL\": {\"value\": %.0f},\"PRE\": {\"value\": %.0f},\"PUMP\": {\"value\": %d}}}",mq_fan,mq_temp,mq_light,mq_led,humidity,soil_h,pressure,mq_pump);
	sprintf(topic,"AT+MQTTPUBRAW=0,\"$sys/xxxxx/FARM/thing/property/post\",%d,0,0\r\n",strlen(pub_dat_buf));
	SendCmd(topic,">",50);//发送需要发布的topic以及数据长度
	HAL_Delay(50);
	esp_send(pub_dat_buf);
}

Android端使用GET获取数据

java 复制代码

public void Get() {
        new Thread(() -> {
            //接受温度
            OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder().url
                    ("https://iot-api.heclouds.com/thingmodel/query-device-property?product_id=xxxxx&device_name=FARM")
                    .addHeader("Authorization", "version=2018-10-31&res=products%2Fxxxxx%2Fdevices%2FFARM&et=1736269477&method=md5&sign=fVpjPaZLpv1%2Btl5zcIcC9A%3D%3D").addHeader("Accept",Accept).build();
            client.newCall(request).enqueue(new Callback() {
                @Override
                public void onResponse(@NonNull Call call, @NonNull Response response) throws IOException {
                    if(!response.isSuccessful()) {
                        throw new IOException("Unexpected code" +response);
                    }else {
                        String responseBody = response.body().string();
                        Log.e("farm",responseBody);//输出响应内容
                        try {
                            JSONArray jsonArray = new JSONArray(responseBody.substring(responseBody.indexOf("["),responseBody.lastIndexOf("]")+1));

                            StringBuilder str= new StringBuilder("httpclient:\n");
                            for (int i=0;i<jsonArray.length();i++)
                            {
                                JSONObject jsonObject2 = (JSONObject)jsonArray.opt(i);
                                String temp_id=jsonObject2.has("identifier")?jsonObject2.getString("identifier"):null;
                                String temp_val=jsonObject2.has("value")? jsonObject2.getString("value"):null;

                                str.append("第").append(i).append("个:").append(temp_id).append(": ").append(temp_val).append("\n");
                                check(temp_id,temp_val);

                            }
                            Log.e("zms", str.toString());
                            Calendar calendar = Calendar.getInstance();
                            str= new StringBuilder(calendar.get(Calendar.MINUTE) + ":" + calendar.get(Calendar.SECOND) + str);
                            check(String.valueOf(str));
                        } catch (JSONException e) {
// TODO Auto-generated catch block
                            Log.e("zms", "err");
                            e.printStackTrace();
                        }


                    }
                }

                @Override
                public void onFailure(@NonNull Call call, @NonNull IOException e) {
                    Log.e("farm","get fail");
                    e.printStackTrace();
                }

            });

        }).start();

    }

Android端发送控制指令使用的POST

java 复制代码

    //异步post请求
    public void Post() {
        RequestBody requestBody = RequestBody.create(MediaType.parse("application/json; charset=utf-8"), "{" +
                "    \"product_id\": \"xxxxx\"," +
                "    \"device_name\": \"FARM\"," +
                "    \"params\": {" +
                "      \"LED\": 0" +
                "    }" +
                "  }");
        Request request = new Request.Builder()
                .url("https://iot-api.heclouds.com/thingmodel/set-device-property")
                .post(requestBody)
                .header("Authorization", "version=2018-10-31&res=products%2Fxxxxx%2Fdevices%2FFARM&et=1772735919&method=md5&sign=QwtaZir04FXz1BeO%2B9FPpQ%3D%3D")
                .build();

        OkHttpClient okHttpClient=new OkHttpClient();
        Call call=okHttpClient.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                Log.e("farm","post fail");//输出响应内容
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                String str=response.body().string();
                //.........
                Log.e("farmPOST",str);//输出响应内容
                if(str.contains("success")){
                    check("set ok");
                }
            }
        });

    }

QT端和Android操作差不多，也是通过get和post

cpp 复制代码

void MainWindow::SendGetRequst()
{
    mNetworkManager = new QNetworkAccessManager(this);
    QNetworkRequest _quest;
    QString url = "https://iot-api.heclouds.com/thingmodel/query-device-property?product_id=xxxxx&device_name=FARM";
    _quest.setUrl((QUrl(url)));
    _quest.setRawHeader("Authorization","version=2018-10-31&res=products%2Fxxxxx%2Fdevices%2FFARM&et=1736269477&method=md5&sign=fVpjPaZLpv1%2Btl5zcIcC9A%3D%3D");
    _quest.setRawHeader("Accept","application/json, text/plain, */*");//自定义
    mReply = mNetworkManager->get(_quest);
    QByteArray _data = mReply->readAll();//读出数据
    //QDateTime::currentDateTime().toString("yyyy-MM-dd hh:mm:ss.zzz").toUtf8().constData();
    qInfo()<<"1_data ==> "<<_data;
    //connect(mReply,&QNetworkReply::finished,this,&HttpOperate::ReplyFinshed);//方式一
    // auto lambdaFun = [=]{ReplyFinshed();};//lambda函数
    // connect(mReply,&QNetworkReply::finished,lambdaFun);//这里的信号的接受者可以省略不写
    connect(mReply,&QNetworkReply::finished,[=]{//这里的信号的接受者可以省略不写
        ReplyFinshed();
    });
    qInfo()<<"2_data ==> " << QDateTime::currentDateTime().toString("yyyy-MM-dd hh:mm:ss.zzz").toUtf8().constData();

}

void MainWindow::SendPostRequst(uint8_t flag)//将控制命令发出去 0 led 1 pump 2 fan
{
    mNetworkManager = new QNetworkAccessManager(this);
    QNetworkRequest _quest;
    _quest.setUrl((QUrl("https://iot-api.heclouds.com/thingmodel/set-device-property")));

    _quest.setRawHeader("Authorization", "version=2018-10-31&res=products%2Fxxxxx%2Fdevices%2FFARM&et=1772735919&method=md5&sign=QwtaZir04FXz1BeO%2B9FPpQ%3D%3D");
    _quest.setHeader(QNetworkRequest::ContentTypeHeader,QVariant("application/json"));
    QJsonDocument document;
    QJsonObject obj,obj1;
    obj.insert("product_id", "xxxxx");
    obj.insert("device_name", "FARM");
    switch (flag) {
    case 0:
        obj1.insert("LED",ui->comboBox->currentIndex());
        break;
    case 1:
        obj1.insert("PUMP",ui->checkBox_4->isChecked() ? 1:0);
        break;
    case 2:
        obj1.insert("FAN",ui->checkBox_2->isChecked() ? 1:0);
        break;
    default:
        return;
        break;
    }


    obj.insert("params", obj1);
    document.setObject(obj);
    QByteArray _postData = document.toJson(QJsonDocument::Compact);//以Json字符串的方式传参
    qDebug()<<_postData;

    _quest.setAttribute(QNetworkRequest::Http2AllowedAttribute, false);
    mReply = mNetworkManager->post(_quest,_postData);
    QByteArray _data = mReply->readAll();//读出数据
    qDebug()<<"1_data ==> "<<_data;//此s时数据为空

    connect(mReply,&QNetworkReply::finished,this,[=]{
        ReplyFinshed();
    });//方式三
    qDebug()<<"2_data ==> ";

}
