使用 PHP 更新 XML 并使用 SOAP 返回 .NET Web 服务数据集

Question

我正在使用 PHP5 和 Codeigniter 通过 SOAP 请求连接到 .NET Web 服务。我在更新该数据集时遇到问题。这是我第一次使用 Codeigniter（尽管这里不考虑太多）、SOAP、PHP SimpleXML 类和一般的 .NET Web 服务。例如，这是更新用户个人资料。我在获取回复方面没有任何问题，但我不确定如何根据用户对个人资料的编辑进行更新。

我的转储请求字符串是这样的（注意：我关心的是 0，它是数据集的开头。1111 是用户名，接下来的 1111 是密码）

11111111 0RandyFloydGM1955-11-05T00:00:00- 04:00317787129131789770001910 E. Markwood AvenueIndianapolisIN46227falsefalse

这给我一个 400 Bad Request 错误。很明显，这是由于 0 和最后一个 1 之间的空格造成的。通过执行 htmlspecialchars() 我发现看起来不需要 xml 声明。

<?xml version="1.0"?> <diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-    msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"><dsEmployee xmlns="http://SHSSrv/dsEmployee.xsd"><Employee diffgr:id="Employee1" msdata:rowOrder="0"><EmplId>0</EmplId><FirstName>Randy</FirstName><LastName>Floyd</LastName><MI>G</MI><Sex>M</Sex><DOB>1955-11-05T00:00:00-04:00</DOB><HomePhoneArea>317</HomePhoneArea><HomePhone>7871291</HomePhone><WorkPhoneArea>317</WorkPhoneArea><WorkPhone>8977000</WorkPhone><Address1>1920 E. Markwood Avenue</Address1><Address2/><City>Indianapolis</City><St>IN</St><ZIP>46227</ZIP><ReceiveNewsLetter>false</ReceiveNewsLetter><PagerArea/><PagerNo/><EmailAddress>[email protected]</EmailAddress><SpanishContact>false</SpanishContact></Employee></dsEmployee></diffgr:diffgram> 

获取原始响应并在更新时将其发回，就像这样。 111111110RandyFloydGM1955-11-05T00:00:00-04:00317787129131789770001910 E.Markwood AvenueIndianapolisIN46227falsefalse

并且 htmlspecialchars() 看起来像这样（没有 XML 声明）：

<diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-    msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"><dsEmployee xmlns="http://SHSSrv/dsEmployee.xsd"><Employee diffgr:id="Employee1" msdata:rowOrder="0"><EmplId>0</EmplId><FirstName>Randy</FirstName><LastName>Floyd</LastName><MI>G</MI><Sex>M</Sex><DOB>1955-11-05T00:00:00-04:00</DOB><HomePhoneArea>317</HomePhoneArea><HomePhone>7871291</HomePhone><WorkPhoneArea>317</WorkPhoneArea><WorkPhone>8977000</WorkPhone><Address1>1920 E. Markwood Avenue</Address1><Address2/><City>Indianapolis</City><St>IN</St><ZIP>46227</ZIP><ReceiveNewsLetter>false</ReceiveNewsLetter><PagerArea/><PagerNo/><EmailAddress>[email protected]</EmailAddress><SpanishContact>false</SpanishContact></Employee></dsEmployee></diffgr:diffgram>

这是代码：

function employee_update_request()
{

    ini_set( 'soap.wsdl_cache_ttl' , 0 );

    //Get XML from the Employee Profile Request
    $response = $this->employee_profile_request();

    //Turn the string into an object to manipulate
    $dataset = simplexml_load_string($response->any);

    //Manipulate some data from the update form
    $dataset->dsEmployee->Employee->EmailAddress = "[email protected]";
    $dataset->dsEmployee->Employee->Address1 = "1920 E. Markwood Avenue";
    $any = $dataset->saveXML();

    //Add back the string to the original response object returned from web service         
    $response->any = $any;

    //Get username and password for the params
    $username = $this->session->userdata('username');
    $password = $this->session->userdata('password');                       
    $params = array('sUserId' => $username, 'sPassword' => $password, 'dsEmployee' => $response);

    //SOAP Options
    $options = array(
            'soap_version'=>SOAP_1_1,
            'exceptions'=> 0,
            'trace'=> 1,
        'uri' => "http://www.w3.org/2003/05/soap-envelope"
            );

        //New soap client with options
        $client = new SoapClient('http://localhost/SHSSRV/SHSSrv.asmx?WSDL', $options);
        //Request the employee profile fromt the webservice, passing in credentials

        $update_request = $client->EmployeeUpdateRequest($params);
        $update_response = $update_request->EmployeeUpdateRequestResult;

        return $update_response;

}

我真的需要帮助，我需要弄清楚如何最好更新此数据。我是否能够以某种方式删除声明，或者我应该请求以某种方式更改 .NET Web 服务？我无法直接访问该内容，但如果有更好的方法，我可以与开发人员交谈。

谢谢！

我已经通过这样做解决了这个问题。我很想知道是否有更好的方法。

$no_xml_doctype = str_replace('<?xml version="1.0"?>' , '' , $any);
$trimmed = trim($no_xml_doctype);   
$response->any = $trimmed;

//Get username and password for the params
$username = rtrim($this->session->userdata('username'));
$password = rtrim($this->session->userdata('password'));                        
$params = array('sUserId' => $username, 'sPassword' => $password, 'dsEmployee' => $response);
