请教下php的soap获取不到返回参数是咋回事呢,缓存也清除了啊

问题遇到的现象和发生背景

但是用soapui就有返回值

ini_set('soap.wsdl_cache_enabled', "0");

try {
$wsdl = 'aaa';
$endpoint = 'bbb';

$client = new SOAPClient($wsdl, array(
    'location' => $endpoint, // 设置server路径
    'uri' => $wsdl,
    'soap_version' => 'SOAP_1_1',
    'trace' => 1,
    'login' => '111', // HTTP auth login
    'password' => '2222' // HTTP auth password,
));


$paraArr = array(
    'I_DATE_F' => "20200101",
    'I_DATE_T' => "20221201",
    'I_TIME_F' => "000001",
    'I_TIME_T' => "000001",
);

$response = $client->Z_SD_CRM_ADDRESS($paraArr);
var_dump($response);die;

} catch (SOAPFault $e) {
print $e->getMessage();

}
