为什么我会收到此错误"falseObject引用未设置为对象的实例".当我在我的webservice中调用一个操作时

Question

我有一个Web服务,我在PHP中使用SOAP客户端调用其中一个操作,但我得到的就是这个 ["any"]=> string(120) "falseObject reference not set to an instance of an object.

我想知道我的代码中有什么问题,因为我相信我与Web服务的连接是%100工作.

我正在创建的xml字符串有什么问题吗？

操作是:

<wsdl:operation name="XmlIslet">
    <wsdl:input message="tns:XmlIsletSoapIn"/>
    <wsdl:output message="tns:XmlIsletSoapOut"/>
</wsdl:operation>

并且它在WSDL中的参数描述是:

<wsdl:types>
    <s:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/">
        <s:element name="XmlIslet">
            <s:complexType>
                <s:sequence>
                    <s:element minOccurs="0" maxOccurs="1" name="xmlIslem">
                        <s:complexType>
                            <s:sequence>
                                <s:any/>
                            </s:sequence>
                        </s:complexType>
                    </s:element>
                    <s:element minOccurs="0" maxOccurs="1" name="xmlYetki">
                        <s:complexType>
                            <s:sequence>
                                <s:any/>
                            </s:sequence>
                        </s:complexType>
                    </s:element>
                </s:sequence>
            </s:complexType>
        </s:element>
        <s:element name="XmlIsletResponse">
            <s:complexType>
                <s:sequence>
                    <s:element minOccurs="0" maxOccurs="1" name="XmlIsletResult">
                        <s:complexType mixed="true">
                            <s:sequence>
                                <s:any/>
                            </s:sequence>
                        </s:complexType>
                    </s:element>
                </s:sequence>
            </s:complexType>
        </s:element>
    </s:schema>
</wsdl:types>

我的soap和PHP代码如下:

<?php
$username = "username";
$password = "password";
$xmlString = "<Firmalar></Firmalar>";

function strtoXmldocument($str)
{
    $dom = new DOMDocument();
    $str1 = $str;
    return $dom->loadXML($str1);
}

function stringToDataset($xmlString, $username, $password)     
{                       
    $client = new SoapClient('http://1.1.1.1/WSTEST/Service.asmx?WSDL');

    $response = $client->XmlIslet(strtoXmldocument($xmlString)->documentElement,  
strtoXmldocument("<Kullanici><Adi>" .$username. "</Adi><Sifre>" .$password. "</Sifre></Kullanici>")->documentElement);

var_dump($response);
}

stringToDataset($xmlString, $username, $password);
?>

SOAP请求如下:

POST /WSTEST/Service.asmx HTTP/1.1
Host: 1.1.1.1
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <XmlIslet xmlns="http://tempuri.org/">
      <xmlIslem>xml</xmlIslem>
      <xmlYetki>xml</xmlYetki>
    </XmlIslet>
  </soap12:Body>
</soap12:Envelope>

SOAP响应:

HTTP/1.1 200 OK
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <XmlIsletResponse xmlns="http://tempuri.org/">
      <XmlIsletResult>xml</XmlIsletResult>
    </XmlIsletResponse>
  </soap12:Body>
</soap12:Envelope>

vardump 输出是:

usernamepasswordobject(stdClass)#2 (1) { ["XmlIsletResult"]=> object(stdClass)#3 (1) { ["any"]=> string(120) "falseObject reference not set to an instance of an object." } } 

编辑: 我试图获取请求xml使用htmlentities($client->__getLastRequest())它显示我的请求的空体:

========= REQUEST ========== 
string(292) 
"<?xml version="1.0" encoding="UTF-8"?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://tempuri.org/">
<SOAP-ENV:Body>
<ns1:XmlIslet>
<ns1:xmlIslem/>
<ns1:xmlYetki/>
</ns1:XmlIslet>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope> "

您很可能正在与 .NET 服务进行通信。该错误消息基本上是“变量未定义”消息。

WSDL 文件指出，您的请求必须包含两个实体：xmlIslem 和 xmlYetki。但它们的内部结构没有正确定义，它可以是“任何”事物。但是，这并不意味着删除 Web 服务不希望您提供一些数据。看起来您需要传递一些数据，但实际上不需要，因此会出现错误。

我会联系网络服务提供商并请求文档或特定请求示例。
