GeocodeModel does not work

import QtQuick 2.0
import QtLocation 5.11
import QtPositioning 5.11

Rectangle{

    // Icone que representa um marcador no mapa
    Image {
        id: ic_marker
        source: "qrc:///icons/icons/ic_map_marker.svg"
        sourceSize.width:  50
        sourceSize.height: 50
    }

    // Plugin responsavel por executar requisicoes de dados para o mapa
    Plugin{
        id: osm
        name: "osm"
        PluginParameter{name: "osm.useragent"; value: "TGAdmin"}
        PluginParameter{name: "osm.mapping.custom.host"; value: "https://tile.openstreetmap.org"}
        PluginParameter{name: "osm.mapping.providersrepository.disabled"; value: true}
    }

    // Marcador da posicao do tiro de guerra no mapa
    MapQuickItem{
        id: tgMarker
        anchorPoint.x: tgMarker.width / 4
        anchorPoint.y: tgMarker.height
        coordinate: QtPositioning.coordinate(latitude, longitude)
        sourceItem: ic_marker
    }

    Address {
        id :fromAddress
        street: "Sandakerveien 116"
        city: "Oslo"
        country: "Norway"
        state : ""
        postalCode: "0484"
    }

    GeocodeModel{
        id: geoAt
        plugin: osm
        autoUpdate: false
    }

    // O mapa em si
    Map{

        id: mapa
        anchors.fill: parent
        plugin: osm
        zoomLevel: 17
        center: QtPositioning.coordinate(latitude, longitude)

        Component.onCompleted: {
            addMapItem(tgMarker)

            geoAt.query = fromAddress
            geoAt.update()

            console.log("Enderecos obtidos: ", geoAt.count)
        }

    }

}

I've been trying to get the geographic coordinates of an address for about a week but nothing is returned.

The rest of the map works normally, I need this because the system I'm developing must trace a route to the address provided by the register.

@Samuel-Ives
GeocodeModel's request is not synchronous. It means your code will always print Enderecos obtidos: 0, because the count has not changed.

If you need to capture the coordinate when the request ends, you may connect a function to locationsChanged signal.
See a example:

GeocodeModel{
        id: geoAt
        plugin: osm
        autoUpdate: false
        onLocationsChanged: { // when reply
            if (count > 0){ // found a location
                console.log(get(0).coordinate); // print the coordinate
            }
        }
    }

[Samuel Ives]

still without any coordinates, I made this small change as suggested:

GeocodeModel{
        id: geoAt
        plugin: osm
        autoUpdate: false
        onLocationsChanged: {

            if(count > 0){

                mapa.Center = QtPositioning.coordinate(get(0).coordinate.latitude, get(0).coordinate.longitude)
                console.log("Coordenadas: ", get(0).coordinate.latitude, " ", get(0).coordinate.longitude)

            }

        }
    }

    // O mapa em si
    Map{

        id: mapa
        anchors.fill: parent
        plugin: osm
        zoomLevel: 17
        center: QtPositioning.coordinate(latitude, longitude)

        Component.onCompleted: {
            addMapItem(tgMarker)

            geoAt.query = fromAddress.text
            console.log("Endereco: ", fromAddress.text)
            geoAt.update()


            console.log("Enderecos obtidos: ", geoAt.count)
        }

    }

And this is the result:

*This time I also tried with a text in place of the address

@Samuel-Ives
i know that GeoCodeModel (using osm) was broken in Qt 5.10 (or at least in the meantime broken) and working again with 5.12.
I can't tell if that was still the case with Qt 5.11

[Samuel Ives]

esri is not working either, I do not think it's a plugin specific problem

[Pablo J. Rogina]

@Samuel-Ives could it be possible you do network traffic capture (i.e. using Wireshark) to check if the request(s) made by the plugin(s) (either osm or esri) are reaching the Internet and what response(s) do you received, if any?
At least you could figure out if the problem is the request/response (network operations) or the display of information received?

[KillerSmath]

@Samuel-Ives
I got the same behavior when i used geoAt.query = fromAddress.text instead of geoAt.query = fromAddress

Edit: It is possible to know if something wrong happens if you connect onStatusChanged signal with a function.

onStatusChanged: {
    if(status === GeocodeModel.Ready){
        console.log("Sucess, the request has been found "+count+" result(s).");
    }
    else if(status === GeocodeModel.Error){
        console.log("Error: " + errorString);
    }
}

[Samuel Ives]

onStatusChanged: {

            switch(geoAt.status){

            case GeocodeModel.Loading:
                console.log("Loading")
                break;

            case GeocodeModel.Ready:
                console.log("Ready")
                break;

            case GeocodeModel.Error:
                console.log("Error: ", errorString)
                break;

            }

        }

I got this

qml: Endereco: Sandakerveien 116<br/>0484 Oslo<br/>Norway
qml: Loading
qml: Enderecos obtidos: 0
qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed
qml: Error: TLS initialization failed

The strangest thing is that I do not remember any time using SSL

From you 1st post:

PluginParameter{name: "osm.mapping.custom.host"; value: "https://tile.openstreetmap.org"}

Are you still using the same values? if so, that could be the answer...

[KillerSmath]

@Samuel-Ives
https://doc.qt.io/qt-5/location-plugin-osm.html#overview

Since Qt 5.9.6 the default nominatim endpoint, used for geocoding and places, has also changed to HTTPS-only.

[Samuel Ives]

Well, I compiled the openssl source code, I added the libraries in my project and added the dlls, but it still has the same error

@Samuel-Ives
https://slproweb.com/download/Win64OpenSSL_Light-1_0_2r.exe
https://doc.qt.io/qt-5/qsslsocket.html#sslLibraryBuildVersionString

[Samuel Ives]

the version returned was OpenSSL 1.0.2p, and the one I compiled was 1.1.1, could that influence something? What I find strange is that I'm not using a ssl resource directly, just that url, the compiler does not accuse me of linking errors regarding openssl

[Samuel Ives]

Problem solved, I downloaded the dlls from here and it worked http://slproweb.com/products/Win32OpenSSL.html, I'm already getting the coordinates, the libraries were not being loaded because they had a different name
