Webservice returns to Soapui, but does not return to PHP

Question

I am consuming a SOAP Webservice and I am found the following problem: Webservice has two functions. In PHP, using the Soapclient class, I created the client and consumes the first function without problem. But when I try to use the second function, it returns me a lot of errors without nexus. But when I try to consume this second function using Soapui, the second function sends the return correctly. My question is: can it be a mistake in Webservice? But if it is, how can Soapui consume the same?

In addition, I have a certain suspicion that the error may be even in Webservice, because when I tried to import WSDL from it in Java or Python, the import fails. And that’s never happened with other web-services I’ve consumed. The path to Webservice is: http://wscaixa.datasysonline.net/wsDadosCaixa.asmx?wsdl

My PHP code:

<?php

    $clientesoap = new SoapClient("http://wscaixa.datasysonline.net/wsDadosCaixa.asmx?wsdl", array(
        'cache_wsdl' => WSDL_CACHE_NONE
    ));

    $xml = "<cartoes>";
    $xml .= "<lancamento>";
    $xml .= "<pedido>XXXX-XXXXX</pedido>";
    $xml .= "<parcela>1</parcela>";
    $xml .= "<nsu>666666</nsu>";
    $xml .= "<valorParcela>36</valorParcela>";
    $xml .= "<valorLiquido>35</valorLiquido>";
    $xml .= "<dtVencimento>10/03/2015</dtVencimento>";
    $xml .= "<dtAntecipacao>12/03/2015</dtAntecipacao>";
    $xml .= "<dtLiquidacao>12/03/2015</dtLiquidacao>";
    $xml .= "<taxaAntecipacao>2</taxaAntecipacao>";
    $xml .= "</lancamento>";
    $xml .= "</cartoes>";  

    $param = new stdClass();
    $param->Token = 'xxxxxxxxxxxxxxxxxxxxxxx';
    $param->Xml = $xml;

    $resultado = $clientesoap->AtualizarConciliacao($param);

    // a funcao abaixo funciona, mas a de cima (AtualizarConciliacao) dá erro:
    // $param->Data '2016-03-03';
    // $resultado = $clientesoap->BaixarVendasCartao($param);


    print_r($resultado);

?>

Hello, Paulo.

I took the liberty of transporting your code to the visual studio and managed to identify the problem.

The error shown indicates that the token would be null, and indeed it is. If you look at the sent parameters, you will see that you only pass the XML and not the token as is the method definition. Even passing it, I got the same error message if you send a token in string format. To function properly you need to convert the token to Base64 string.

In C#, the conversion of your token would be like this:

var encoding = System.Text.Encoding.UTF8;
byte[] textAsBytes = encoding.GetBytes(token);
string base64String = System.Convert.ToBase64String(textAsBytes);

So, when you call, you call: client.Updatelogin(base64String, docxml);

The error message will occur, but will now be indicating "Invalid Token." which is a standard webservice message in token validation.

From what I read in documentation from PHP, the command for you would be:

(...)   
$tokenBase64 = base64_encode($token);
$resultado = $clientesoap->AtualizarConciliacao($tokenBase64, $xml);

I hope it helps. Abs
