基于百度地图Web API的物联设备调试工具(一)

该工程源于一个测试工具的开发, 涉及到串口收发, 网络数据收发, Qt与Js的交互, 经纬度距离计算等.

效果如下:

串口相关

//串口轮询void Frame::fillPortsInfo(){    static const QString blankString = QObject::tr("N/A");    QString description;    QString manufacturer;    QString serialNumber;    int i = 0;    ui->comboBoxSerial->clear();    foreach (const QSerialPortInfo &info, QSerialPortInfo::availablePorts())    {        QStringList list;        description = info.description();        manufacturer = info.manufacturer();        serialNumber = info.serialNumber();        list << info.portName()             << (!description.isEmpty() ? description : blankString)             << (!manufacturer.isEmpty() ? manufacturer : blankString)             << (!serialNumber.isEmpty() ? serialNumber : blankString)             << info.systemLocation()             << (info.vendorIdentifier() ? QString::number(info.vendorIdentifier(), 16) : blankString)             << (info.productIdentifier() ? QString::number(info.productIdentifier(), 16) : blankString);        QString portName = list.first();        ui->comboBoxSerial->insertItem(i, portName);        i++;    }}//打开串口void Frame::openSerialPort(){    serial->setPortName(ui->comboBoxSerial->currentText());    serial->setBaudRate(QSerialPort::Baud115200);    serial->setDataBits(QSerialPort::Data8);    serial->setParity(QSerialPort::NoParity);    serial->setStopBits(QSerialPort::OneStop);    serial->setFlowControl(QSerialPort::NoFlowControl);    if (serial->open(QIODevice::ReadWrite))    {            ui->console->setEnabled(true);            ui->console->setLocalEchoEnabled(true);            ComFlag = true;            return;    }    else        ComMcuFlag = false;}//读串口connect(serial, SIGNAL(readyRead()), this, SLOT(SerialReadData()));void Frame::SerialReadData(){    QByteArray data = serial->readAll();    ui->console->putData(data);}//写串口void Frame::SerialWriteData(const QByteArray &data){    serial->write(data);}

网络相关

//略

Web相关

TCP Server接收到移动终端上传得位置数据(GPS, LBS, WIFI等)后, 解析相关数据, 构建Web请求字符串, 发送Http请求.QNetworkRequest request;QString reqUrl;QString infoStr;QNetworkAccessManager* manager;//发送GPS请求reqUrl.sprintf("http://api.map.baidu.com/geoconv/v1/?coords=%.6f,%.6f&ak=申请的key&output=xml", lng.a, lat.a);infoStr=QString("设备:%1 电量:%2 %3").arg(imei).arg(dev_voltage).arg(dev_utc);request.setAttribute(QNetworkRequest::User,infoStr);request.setUrl(QUrl(reqUrl));manager->get(request);//发送LBS请求reqUrl.sprintf("http://api.gpsspg.com/bs/?oid=5039&key=4153C361801F6CA3A06087702FD1994F&bs=%x,%x,%d,%d&to=2&output=xml",                    mcc.a, mnc, lac.a, ceilid.a);infoStr=QString("设备:%1 电量:%2 %3").arg(imei).arg(dev_voltage).arg(dev_utc);request.setAttribute(QNetworkRequest::User,infoStr);request.setUrl(QUrl(reqUrl));manager->get(request);//Http响应处理connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(httpReplyFinish(QNetworkReply*)));void Frame::httpReplyFinish(QNetworkReply* reply){    QString result = reply->readAll().simplified();    QString url    = reply->url().toString();    QVariant userData = reply->request().attribute(QNetworkRequest::User);    QString userDataStr = userData.value<QString>();    if (url.contains("api.gpsspg.com"))    {        //在这里解析返回的addrsss, roads, latitude, longitude略        //定位并添加标注        JyGAPI->GisShowAddressWithTitle(lat.a,lng.a, userDataStr);        itemStr.sprintf("L: %.6f,%.6f", lat.a, lng.a);        pos_vec.push_back(itemStr);        item = new QStandardItem(itemStr);        standardItemModel->setItem(pos_vec.size()-1, item);    }    else if (url.contains("api.map.baidu.com"))    {        //在这里解析纠偏后的经纬度, 略        //定位并添加标注        JyGAPI->GisShowAddressWithTitle(dlat,dlng, userDataStr);        itemStr.sprintf("G: %.6f,%.6f", dlat, dlng);        pos_vec.push_back(itemStr);        item = new QStandardItem(itemStr);        standardItemModel->setItem(pos_vec.size()-1, item);    }}
