Question

尝试使用PHP使用Java Web服务时出现以下错误：java.lang.NullPointerException。

我认为it boils down to passing the parameter correctly。但是，此链接在我的情况下不起作用（提供stdClass对象）。

这是WSDL的相关部分

...
<message name="queryByPartyId">
    <part name="parameters" element="tns:queryByPartyId"/>
</message>
...
<operation name="queryByPartyId">
    <soap:operation soapAction=""/>
    <input><soap:body use="literal"/></input>
    <output><soap:body use="literal"/></output>
    <fault name="ServiceFault"><soap:fault name="ServiceFault" use="literal"/></fault>
</operation>

相关的PHP代码：

//things I've tried

//$theResponse = $soapClient->queryByPartyId("12345");
//$theResponse = $soapClient->__soapCall("queryByPartyId", array("queryByPartyId"=>12345));
//$theResponse = $soapClient->__soapCall("queryByPartyId", array("12345"));


//$addRequest = new stdClass();
//$addRequest->queryByPartyId = 12345;
//$theResponse = $soapClient->queryByPartyId($addRequest);

$theResponse = $soapClient->queryByPartyId(array("queryByPartyId"=>12345));

var_dump($theResponse);

$theResponse的格式转储：

在WSDL中找不到元素标记，但是存在模式位置。加载时，找到以下元素标记

<xs:complexType name="queryByPartyId">
    <xs:sequence>
        <xs:element name="queryByPartyIdInMsg" type="tns:queryByPartyIdInMessage" minOccurs="0"/>
    </xs:sequence>
</xs:complexType>
<xs:complexType name="queryByPartyIdInMessage">
    <xs:sequence>
        <xs:element name="partyId" type="xs:string" minOccurs="0"/>
    </xs:sequence>
</xs:complexType>

更新＃3

解决方案：

$addRequest = new stdClass();
$queryByPartyIdInMsg = new StdClass();

$queryByPartyIdInMsg->partyId="12345";
$addRequest->queryByPartyIdInMsg = $queryByPartyIdInMsg;

$theResponse = $soapClient->queryByPartyId($addRequest);

var_dump($theResponse);

找到元素结构后，the link mentioned previously actually helped to find the solution。

再看看wsdl文件，在那里的某个地方，你会看到这样的东西：

<element name="queryByPartyId">
    <complexType>
        <element name="foobar" type="foo:int"/>
    </complexType>
</element>

这是服务在调用时希望您传递的内容的描述。内部elements具有name和type属性。要将其转换为通话，请执行以下操作：

$response = $soapClient->queryByPartyId(array('foobar'=> 123456));
var_dump($response);

wsdl 应该还包含服务将返回的描述：

<element name="queryByPartyIdResponse">
    <complexType>
        <element name="PartyReturn" type="xs:SomeType" />
    </complexType>
</element>

在此示例中，响应将是一个对象（或您的soapclient返回的任何对象），其中包含1个属性：PartyReturn，该属性的类型为SomeType。如果它是自定义类型（Java类），wsdl文件也将包含对它的描述。

在你的情况下：

$response = $soapClient->queryByPartyId(
    array('queryByPartyIdInMsg' => array('PartyId' => 123456))
);

或许您需要将queryByPartyIdInMsg子数组包装到另一个数组中，因为两个complexTypes的minOccurs都为0（表示数组）
