Nusoap返回空白<return xmlns =“”>标记

Question

我在YII中使用Nusoap库来获取WSDL，但我得到了空白的响应。

我的代码：

public function actionNuSoap() {
    $namespace = "u`enter code here`rn:bureauRequest";
    $HTTP_RAW_POST_DATA = file_get_contents('php://input');
    Yii::import('application.extensions.nusoap.lib.*');
       require_once('nusoap.php');

    function bureauRequest($AXIS_APP, $PURPOSE, $SUBPURPOSE, $VERSION, $SRNO, $APPLICATION, $SUBMISSION_DATE, $SUBMISSION_TIME, $WRITE_FLAG, $DEDUPE_FLAG, $LOAN_ID, $PRODUCT_CODE
    , $LOAN_AMOUNT, $FNAME, $MNAME, $LNAME, $DOB, $SEX, $ADDRESS1, $ADDRESS2, $ADDRESS3, $ADDRESS4, $ADDRESS5, $STATE, $ZIPCODE, $PHONE
    , $OFFADDRESS1, $OFFADDRESS2, $OFFADDRESS3, $OFFADDRESS4, $OFFADDRESS5, $OFFSTATE, $OFFZIPCODE, $OFFPHONE, $PAN_NO, $PASSPORT_NO
    , $VOTER_ID, $DRIVER_LICENSCE, $RATION_CARD, $CREDIT_CARD, $MOBILE_NO, $ACCOUNT_NO, $INTERNAL_SYSTEM_FIELDS, $CUST_ID_N, $CITY, $FREE_TEXT1, $FREE_TEXT2, $FREE_TEXT3, $FREE_TEXT4, $FREE_TEXT5) {
        return array('item'=>'i amin');
      }
    $server = new soap_server;
    $server->configureWSDL('bureauRequest', $namespace);
    $server->wsdl->schemaTargetNamespace = $namespace;

    $server->register('bureauRequest', 
            array(

            array(
                'return'=>'xsd:Array'

            ),
            $namespace, 
            $namespace . '#bureauRequest',
            'document', 'literal', 
            'Get a listing of products by categor'
            );

            $POST_DATA = isset($GLOBALS['HTTP_RAW_POST_DATA']) ? $GLOBALS['HTTP_RAW_POST_DATA'] : '';

            // pass our posted data (or nothing) to the soap service
            $server->service($POST_DATA);
 }
