模拟GPS数据，以便使用Qt与Traccar一起使用

Question

我正在尝试用QT c ++编写GPS模拟器。它将用于将数据发送到Traccar跟踪应用程序。Traccar 使用本地主机端口 5055 接收数据包，并使用数据包中的数据绘制位置。我没有成功让traccar读取数据包。Traccar希望看到HTML格式的数据包。我不确定我的程序是否正确格式化了数据。所有以//\ 开头的行都显示了我尝试过的内容。

这是将数据写入 loalhost 端口 5055 的程序的一部分：

// write to localhost if timer seconds is greater than or equal to desired time
if(scnds >= ui -> updateBox -> text().toDouble()) { 
//\   QString sendString = "/?id=" + id$ + "&Lat=" +lat$ + "&Lon=" + lon$ + "&Speed=" + speed$ + "&Course=" + course$ + "rnrnrnrn";
//\   QString sendString = "/?id=" + id$ + "&Lat=" +lat$ + "&Lon=" + lon$ + "&Speed=" + speed$ + "&Course=" + course$;
//\   QString sendString = "id=" + id$ + "&Lat=" +lat$ + "&Lon=" + lon$ + "&Speed=" + speed$ + "&Course=" + course$ + "rnrnrnrn";
//\   QString sendString = "id=" + id$ + "&Lat=" +lat$ + "&Lon=" + lon$ + "&Speed=" + speed$ + "&Course=" + course$;
QString sendString = "/?id=123456&lat=40.730610&lon=-73.935600&speed=100&Course=45rnrnrnrn";
//\   QString sendString = "/?id=123456&lat=40.730610&lon=-73.935600&speed=100&Course=45";
//\   QString sendString = "id=123456&lat=40.730610&lon=-73.935600&speed=100&Course=45rnrnrnrn";
//\   QString sendString = "id=123456&lat=40.730610&lon=-73.935600&speed=100&Course=45";
QByteArray gpsdata = sendString.toUtf8();//     .toLocal8Bit(); .toUtf8(); .toLatin1();    
socket = new QTcpSocket(this);
socket -> connectToHost("localhost",5055);
if (socket -> waitForConnected(3000)){
ui -> receivedMessage -> append("Connected");
socket -> write(gpsdata);
socket -> waitForBytesWritten(1000);
socket -> waitForReadyRead(3000);
ui -> receivedMessage -> append(QString::number(socket -> bytesAvailable()) + " ");
ui -> receivedMessage -> append(socket -> readAll());
socket -> close();
ui -> sentMessage -> setText(gpsdata);
}
else {
ui -> receivedMessage -> append("Not connected");
ui -> timerLabel -> setNum(0);
}

tracca 日志显示以下内容：

2020-01-18 18:36:41  INFO: [afa16fa9] connected
2020-01-18 18:36:41  INFO: [afa16fa9: osmand < 0:0:0:0:0:0:0:1] HEX: 2f3f69643d313233343536266c61743d33322e35343738266c6f6e3d2d39392e373435322674696d657374616d703d302668646f703d3526616c7469747564653d3130302673706565643d31303020485454502f312e31200d0a0d0a0d0a0d0a

如您所见，traccar 日志显示程序正在连接，但数据未被解码。我知道traccar有效，因为我可以从解码和绘制的网络浏览器发送数据。

任何建议将不胜感激。

试试这个。它对我的工作：

void MainWindow::on_pushButton_3_clicked()
{
QString sendString = "/id=123456&lat=50.030610&lon=33.335600&speed=100&Course=45";
QUrl theurl;
theurl = "http://127.0.0.1:5055";
QByteArray gpsdata = sendString.toUtf8();
qDebug()<<gpsdata;
socket = new QTcpSocket(this);
socket -> connectToHost(theurl.host(),5055);
if (socket -> waitForConnected(3000)){
socket->write("GET /?id=123456&lat=50.030610&lon=33.335600&speed=100&Course=45 HTTP/1.1rn"
"host: " + theurl.host().toUtf8() + "rnrn");
socket -> waitForBytesWritten(1000);
socket -> waitForReadyRead(1000);
QByteArray ba;
ba.append(socket -> readAll());
socket -> close();
qDebug()<<ba;
}
}
