当使用 Soap 服务时，结果为空，这就是为什么在 getLastResponse 中填充 XML 的原因。这是 WSDL:

PHP 代码:

$client = new SoapClient("SearchWebService.wsdl", array('location' => "$usingSSL://$hostname/axis2/services/SearchWebService", 'trace' => 1, 'exceptions' => 1));
$data = json_decode(stripslashes($_POST["data"]));
$result = $client->Search($data);

__getLastResponse:

        </n:SearchResponse>
    </soapenv:Body>
</soapenv:Envelope>

$result 始终为空。没有错误。我尝试了类图和相同的结果。

有什么想法吗？

最佳答案

尝试对结果进行 var_dump()...您看到了什么？

此外，您也可以尝试这个，将其包装在搜索调用周围:

try {
  $result = $client->Search($data);
} catch (SoapFault $exception) {
  //We errored 
  echo $exception;
}
