Question

我用php Soapserver在php中创建了一个soap服务器。我创建了一个函数'addItems'，在第一个参数和相应的wsdl文档中添加多个项目作为数组。在wsdl中，我创建了一个数组对象'items'，如下所示：

<s:complexType name="items"> 
        <s:sequence> 
            <s:element nillable="true" name="item" type="tns:item" minOccurs="0" maxOccurs="unbounded"/> 
        </s:sequence> 
     </s:complexType>

php函数只是一个传递给php soapserver的简单类方法，如下所示：

<?php
class Test
{
     public function addItems($items) {
         print_r($items);
     }
}
$service = new Test();
$server = new SoapServer('wsdl.xml');
$server->setObject();
print($server->handle());

问题就像php soapserver处理数组一样。当我只添加一个项目时，项目列表不会作为数组返回。当我添加两个项目时，项目数组存储在item元素而不是期望的items参数中。

我尝试使用soapenc：array，但这似乎与http://www.ws-i.org/Profiles/BasicProfile-1.0-2004-04-16.html#refinement16556272中提到的WS-I合规性不兼容，而且当我想在使用这种类型的编码时将服务添加到visual studio时，它也会失败。 / p>

那么我做错了什么？我想我必须在某个地方改变wsdl，但找不到一个有效的例子。或者我是否必须为soapserver设置一些选项？我输了。

下面是请求，实际结果和预期结果：

请求一项：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:addItems" xmlns:wsdl="http://base.shopzonline.com/soap/api/test/?wsdl">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:addItems>
         <items>
            <!--Zero or more repetitions:-->
            <wsdl:item>
               <wsdl:id>1</wsdl:id>
               <wsdl:name>a</wsdl:name>
            </wsdl:item>

         </items>
      </urn:addItems>
   </soapenv:Body>
</soapenv:Envelope>

$ items参数的实际结果

    Array
    (
        [item] => Array
        (
             [id] => 1
             [name] => a
        )
    )

$ items参数的预期结果

Array
    [0] => (
        Array
           (
                [id] => 1
                [name] => a
            )
    )

请求多个：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:addItems" xmlns:wsdl="http://base.shopzonline.com/soap/api/test/?wsdl">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:addItems>
         <items>
            <!--Zero or more repetitions:-->
            <wsdl:item>
               <wsdl:id>1</wsdl:id>
               <wsdl:name>a</wsdl:name>
            </wsdl:item>

            <wsdl:item>
               <wsdl:id>2</wsdl:id>
               <wsdl:name>b</wsdl:name>
            </wsdl:item>          
         </items>
      </urn:addItems>
   </soapenv:Body>
</soapenv:Envelope>

$ items参数的实际结果

Array
(
    [item] => Array
        (
            [0] => Array
                (
                    [id] => 1
                    [name] => a
                )

            [1] => Array
                (
                    [id] => 2
                    [name] => b
                )

        )
)

预期结果

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => a
        )

    [1] => Array
        (
            [id] => 2
            [name] => b
        )
)

Answer 1

您可以通过在SoapServer上启用SOAP_SINGLE_ELEMENT_ARRAYS来解决此问题：

$server = new SoapServer('wsdl.xml', [
    'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
]);

Answer 2

我没有测试此解决方案，但您可以查看：

在消息部分中：

<message name="getItemsResponse">
    <part name="items" type="ns:ArrayOfItems"/>
</message>

类型部分：

<xsd:schema targetNamespace="http://foo.bar/objectsoapserver/types"
            xmlns="http://foo.bar/objectsoapserver/types">
    <xsd:complexType name="ArrayOfItems">
        <xsd:complexContent>
            <xsd:restriction base="soapenc:Array">
                <xsd:attribute ref="soapenc:arrayType" soap:arrayType="ns:Items[]"/>
            </xsd:restriction>
        </xsd:complexContent>
    </xsd:complexType>
    <xsd:complexType name="Items">
        <xsd:sequence>
            <xsd:element name="name" type="xsd:string"/>
            <xsd:element name="id" type="xsd:int"/>
        </xsd:sequence>
    </xsd:complexType>
    <xsd:element name="Items" nillable="true" type="ns:Items"/>
</xsd:schema>

顺便说一句。为什么不使用库自动生成WSDL？
