Phonegap Geolocation connected to Server API

问题

Into the mobile app I'm adding GeoLocation for search results which is connected to webserver API however it's always returning "not available".

Javascript

function getCurrentLocation()
{   
    navigator.geolocation.getCurrentPosition(geolocationSuccess,geolocationError, 
    { enableHighAccuracy: true } ); 
}

function geolocationSuccess(position)
{
    var params="lat="+position.coords.latitude;
    params+="&lng="+position.coords.longitude;
    callAjax("reverseGeoCoding",params);
}

function geolocationError(error)
{
    alert('code: '    + error.code    + '\n' +
          'message: ' + error.message + '\n');
}

PHP (API side)

public function actionReverseGeoCoding()
{       
    if (isset($this->data['lat']) && !empty($this->data['lng'])){
        $latlng=$this->data['lat'].",".$this->data['lng'];
        $file="https://maps.googleapis.com/maps/api/geocode/json?latlng=$latlng&sensor=true";
        if ($res=file_get_contents($file)){
            $res=json_decode($res,true);
            if (AddonMobileApp::isArray($res)){
                $this->code=1; $this->msg="OK";
                $this->details=$res['results'][0]['formatted_address'];
            } else  $this->msg=$this->t("not available");
        } else $this->msg=$this->t("not available");
    } else $this->msg=$this->t("missing coordinates");
    $this->output();
}

And I've defined the permission in config.xml

<gap:plugin name="cordova-plugin-geolocation" />

Any advice please?

EDIT example of @Banik

public function actionReverseGeoCoding()
{       
    if (isset($this->data['lat']) && !empty($this->data['lng'])){
        $latlng=$this->data['lat'].",".$this->data['lng'];
        $file="https://maps.googleapis.com/maps/api/geocode/json?latlng=".$latlng."&sensor=true";
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $file);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
        curl_setopt($ch, CURLOPT_HEADER, 0); 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
        $data = curl_exec($ch);
        if ($res==$data){
            $res=json_decode($res,true);
            if (AddonMobileApp::isArray($res)){
                $this->code=1; $this->msg="OK";
                $this->details=$res['results'][0]['formatted_address'];
            } else  $this->msg=$this->t("not available");
        } else $this->msg=$this->t("not available");
    } else $this->msg=$this->t("missing coordinates");
    $this->output();
}
