Get deadline with Post Office Web Service

Question

Get deadline with Post Office Web Service

I am trying to get the delivery time dynamically using the Post Office WebService, for this I am using this documentation .

If you enter their Testing page , you can enter the PAC service, for example 4510 and the source and destination ceps to get the return in an XML page.

I checked that this form makes a simple POST by copying it to my localhost. But when trying to do it without the form, but yes using curl I did not succeed.

My code so far is:

$data['nCdServico'] = '4510';
$data['sCepOrigem'] = '36572008';
$data['sCepDestino'] = '36700000';

$url = 'http://ws.correios.com.br/calculador/CalcPrecoPrazo.asmx/CalcPrazo';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$resp = curl_exec($ch);
curl_close($ch);

var_dump($resp);exit;

But the return is false

I would like a help to know what I am forgetting so that the return is the data of the sending deadline and not just the false boolean.

PHP has the Native librarySoapClient which abstracts many aspects of the consumption of a webservice.

To connect with WS, it's simple:

$client = new SoapClient('http://ws.correios.com.br/calculador/CalcPrecoPrazo.asmx?WSDL');

You must pass as a parameter the address of the WSDL, which is the description of how to consume the web service.

You can also pass some parameters as below:

$client = new SoapClient(
    'http://ws.correios.com.br/calculador/CalcPrecoPrazo.asmx?WSDL',
    array( 
        // Stuff for development. 
        'trace' => 1, 
        'exceptions' => true, 
        'cache_wsdl' => WSDL_CACHE_NONE
    ) 
);

trace: enable debug functions (all start with "__").
Exceptions: will activate that errors will be launched via exceptions (SoapFault)
cache_wsdl: with the parameter WSDL_CACHE_NONE, there will be no cache.

All parameters are focused for development.

After, the use is as simple as:

$data['nCdServico'] = '4510';
$data['sCepOrigem'] = '36572008';
$data['sCepDestino'] = '36700000';

$response = $client->CalcPrazo($data);

The query result is:

object(stdClass)#2 (1) {
  ["CalcPrazoResult"]=>
  object(stdClass)#3 (1) {
    ["Servicos"]=>
    object(stdClass)#4 (1) {
      ["cServico"]=>
      object(stdClass)#5 (8) {
        ["Codigo"]=>
        int(4510)
        ["PrazoEntrega"]=>
        string(1) "5"
        ["EntregaDomiciliar"]=>
        string(1) "S"
        ["EntregaSabado"]=>
        string(1) "N"
        ["Erro"]=>
        string(0) ""
        ["MsgErro"]=>
        string(0) ""
        ["obsFim"]=>
        string(0) ""
        ["DataMaxEntrega"]=>
        string(10) "20/08/2018"
      }
    }
  }
}

Being a stdClass, properties must be accessed as an object (since, it is an objet):

echo "Data máxima de entrega: ".$response->CalcPrazoResult->Servicos->cServico->DataMaxEntrega;

Output:

Maximum delivery date: 20/08/2018
