Google API Matrix: erro no retorno

Recommended Posts

Carlos Rocha

Estou usando o seguinte método para calcular a distancia entre 2 cidades usando Google API Matrix:

      private function calculaDistancia () {
        $this->destino =  str_replace(" ","%20",$this->phpUtil->limpaCaracters($this->destino));
        $url = "https://maps.googleapis.com/maps/api/distancematrix/xml?origins=".$this->origem."-".$this->estadoOrigem."&destinations=".$this->destino."-".$this->estadoDestino."&mode=".$this->mode."&language=".$this->language."&sensor=false";   
       print $url;
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_FAILONERROR, true);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        $data = curl_exec($ch);        
        $freteXML = simplexml_load_string($data);
        $distancia = $freteXML->row->element->distance->value;
        return $distancia;

De fato funciona. E a url de pesquisa é:

    $url = "https://maps.googleapis.com/maps/api/distancematrix/xml?origins=".$this->origem."-".$this->estadoOrigem."&destinations=".$this->destino."-".$this->estadoDestino."&mode=".$this->mode."&language=".$this->language;   

Bom, o problema é que em uma consulta tive a seguinte url de entrada:


Que retornou o seguinte:

      <origin_address>Muriaé, MG, Brasil</origin_address>
      <destination_address>Macapá, AP, Brasil</destination_address>

Note que ele identifica as cidades mas não consegue calcular as disâncias.

Algum recurso?
