Get deadline with the Web Service of the Post Office

I'm trying to get the deadline dynamically using the Post Office WebService, so I'm using this documentation .

If you enter the test page , you can enter the CAP, for example, 4510 and the source and destination ceps to get the return on an XML page.

I've found that this form does a simple POST by copying it to my localhost. But when I try to do it without the form, but 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 some help to know what I'm forgetting so that the return is the data of the submission deadline and not just the boolean false.

PHP has the native library SoapClient that abstracts many aspects of webservice consumption.

To connect with WS, it's simple:

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

You should pass the WSDL address, 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 enable errors to be thrown via exceptions (SoapFault)
cache_wsdl : with the parameter WSDL_CACHE_NONE , there will be no cache.

All parameters are focused on development.

Next, use is as simple as:

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

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

The result of the query 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 stdClass , the properties should be accessed as an object (therefore, it is an objet):

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

Output:

Maximum delivery date: 20/08/2018
