Webservice PHP Soap

Question

Opa Personal, Good Afternoon!

I’m having trouble consuming a webservice.

Fis a basic program to consume but is presenting the following error message: "Request should be informed".

I could not understand what this request would be.

Could you help me?

Follows my source:

  $mensagem = array('Emitir' =>array('Aliquota'=>0,
                               'Atividade'=>1.03,
                               'CEPPrestacaoServico'=>'',
                               'ChaveAutenticacao'=>'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX',
                               'CidadePrestacaoServico'=>'',

$function = 'Emitir';

$options = array('location' => 'https://nfe.osasco.sp.gov.br/EISSNFEWebServices/NotaFiscalEletronica.svc');



   $client = new SoapClient('https://nfe.osasco.sp.gov.br/EISSNFEWebServices/NotaFiscalEletronica.svc?Wsdl');

   $result = $client->__soapCall($function,$mensagem,$options);       


   echo 'Response: ';
   print_r($result);

Thank you

Samuel
