【问题描述】：

我正在与 Soap Web 服务进行交互，我想从 soap 对象中读取值。我总是遇到异常。见下文；

肥皂样品；

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <c2b:C2BPaymentValidationRequest xmlns:c2b="http://cps.huawei.com/cpsinterface/c2bpayment">
         <TransID>3IN40005PY</TransID>
         <TransTime>20160923143639</TransTime>
         <TransAmount>3000</TransAmount>
         <BusinessShortCode>10069</BusinessShortCode>
         <MSISDN>86812530102</MSISDN>
         <KYCInfo>
            <KYCName>FirstName</KYCName>
            <KYCValue>aaa</KYCValue>
         </KYCInfo>
         <KYCInfo>
            <KYCName>MiddleName</KYCName>
            <KYCValue>bbb</KYCValue>
         </KYCInfo>
         <KYCInfo>
            <KYCName>LastName</KYCName>
            <KYCValue>ccc</KYCValue>
         </KYCInfo>
      </c2b:C2BPaymentValidationRequest>
   </soapenv:Body>
</soapenv:Envelope>

我尝试制作一个对象

$xml=simplexml_load_string($response) or die("Error: Cannot create object");

以便我可以读取以下值；

$TransID=$xml->TransID; $TransTime=$xml->TransTime; $TransAmount=$xml->TransAmount;

但是这里失败了 die("Error: Cannot create object");

或者更好的是如何将soap请求更改为json并获取值？有人吗？

【解决方案1】：

您的代码中似乎缺少namespace declaration (php manual) for SOAP。


$xml = simplexml_load_string($xml_data);
$xml->registerXPathNamespace('c2b', 'http://cps.huawei.com/cpsinterface/c2bpayment');
$response = $xml->xpath('//c2b:C2BPaymentValidationRequest')  or die("Error: Cannot create object");

print_r($response);

输出：


Array
(
    [0] => SimpleXMLElement Object
        (
            [TransID] => 3IN40005PY
            [TransTime] => 20160923143639
            [TransAmount] => 3000
            [BusinessShortCode] => 10069
            [MSISDN] => 86812530102
            [KYCInfo] => Array
                (
                    [0] => SimpleXMLElement Object
                        (
                            [KYCName] => FirstName
                            [KYCValue] => aaa
                        )

                    [1] => SimpleXMLElement Object
                        (
                            [KYCName] => MiddleName
                            [KYCValue] => bbb
                        )

                    [2] => SimpleXMLElement Object
                        (
                            [KYCName] => LastName
                            [KYCValue] => ccc
                        )

                )

        )
