Question

我想调用Web服务，该服务也在开发中，并且在WSDL中定义了一个函数PlaceInvoiceFromStream。函数定义了一个要传递的参数，即Invoice。在XSD shema中定义的WSDL导入类型。

WSDL看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<definitions name ="inService"
    xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
    xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"

            <soap:address location="http://localhost/ebiz/ws/soapServer.php"/>
        </port>
    </service>
</definitions>

UBL 2.1架构：http://docs.oasis-open.org/ubl/prd2-UBL-2.1/UBL-2.1.html#SCHEMAS

Invoice是复杂数据，保存在XML文件中，包含名称空间和属性。它是这样开始的：

<?xml version="1.0" encoding="UTF-8"?>
<Invoice
 xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
 xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
 xmlns:sac="urn:oasis:names:specification:ubl:schema:xsd:SignatureAggregateComponents-2"
 xsi:schemaLocation="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2 http://localhost/ebiz/ws/Invoice.xsd"
 xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
 xmlns:sig="urn:oasis:names:specification:ubl:schema:xsd:CommonSignatureComponents-2">
    <ext:UBLExtensions>
        <ext:UBLExtension>
            <cbc:ID>INVOICE1</cbc:ID>
            <cbc:Name>InvoiceIssuePlaceData</cbc:Name>
            <ext:ExtensionAgencyURI>urn:invoice:issueplace</ext:ExtensionAgencyURI>
            <ext:ExtensionContent>
                <ext:InvoiceIssuePlace>MyCity</ext:InvoiceIssuePlace>
            </ext:ExtensionContent>
        </ext:UBLExtension>
    </ext:UBLExtensions>
    <cbc:UBLVersionID>2.1</cbc:UBLVersionID>
    <cbc:ID>01 1206-2406-568</cbc:ID>`

等...

我尝试过这种方法：

// LOAD XML and TRANSFORM FOR SoapClient 
$xmlfile = "Invoice123.xml";
$xslfile = "xsltForSoapClientRequest.xsl";
$xmlDOM = new DOMDocument();
$xmlDOM->load($xmlfile);
$xslDOM = new DOMDocument();
$xslDOM->load($xslfile);
$proc = new XSLTProcessor;
$proc->importStyleSheet($xslDOM);
$transformedXML = $proc->transformToDoc($xmlDOM);
$xmldoc = simplexml_load_string($transformedXML);

// CREATE ARRAY
$xmlarr = xml2array($xmldoc->asXML());

$client = new SoapClient($wsdl,array('trace'=>1));
$result=$client->PlaceInvoiceFromStream($xmlarr);

但没有成功。

XSL转换的变化是：

节点属性成为节点元素
复杂节点值变为“_”元素

xml2array的更改是：

属性变为单独的数组

因此，要发送到Web服务功能的$ xmlarr采用以下形式：

array(2) {
  ["Invoice"]=>
  array(15) {
    ["ext:UBLExtensions"]=>
    array(1) {
      ["ext:UBLExtension"]=>
      array(4) {
        ["cbc:ID"]=>
        string(10) "INVOICE1"
        ["cbc:Name"]=>
        string(21) "InvoiceIssuePlaceData"
        ["ext:ExtensionAgencyURI"]=>
        string(25) "urn:invoice:issueplace"
        ["ext:ExtensionContent"]=>
        array(1) {
          ["ext:InvoiceIssuePlace"]=>
          string(7) "MyCity"
        }
      }
    }
    ["cbc:UBLVersionID"]=>
    string(3) "2.1"
    ["cbc:ID"]=>
    string(16) "01 1206-2406-568"
...

  ["Invoice_attr"]=>
  array(8) {
    ["xmlns"]=>
    string(54) "urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"
    ["xmlns:xsi"]=>
    string(41) "http://www.w3.org/2001/XMLSchema-instance"
    ["xmlns:cac"]=>
    string(72) "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
    ["xmlns:cbc"]=>
    string(68) "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
    ["xmlns:sac"]=>
    string(75) "urn:oasis:names:specification:ubl:schema:xsd:SignatureAggregateComponents-2"
    ["xmlns:ext"]=>
    string(72) "urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
    ["xmlns:sig"]=>
    string(72) "urn:oasis:names:specification:ubl:schema:xsd:CommonSignatureComponents-2"
    ["xsi:schemaLocation"]=>
    string(93) "urn:oasis:names:specification:ubl:schema:xsd:Invoice-2 http://localhost/ebiz/ws/Invoice.xsd"
  }
}

Web服务调用的结果是：

SOAP-ERROR: Encoding: object has no 'UBLExtensions' property

正确的SOAP请求应该是什么形式？ SOAP请求需要什么形式的数组？ SOAP是否基于WSDL和XSD理解“_”元素？或者单独数组中的属性？

提前感谢您解决此问题的任何帮助...

更新：

更改了wsdl：

<message name="getPlaceInvoiceInput">
    <part name="Invoice" element="xsdl:InvoiceType"/>

SoapClient接受以下请求：

$xmlarr = array(
    "UBLExtensions"=>
    array(
      "UBLExtension"=>
      array(
        "ID"=>"INVOICE1",
        "Name"=>"InvoiceIssuePlaceData",
        "ExtensionAgencyURI"=>"urn:invoice:issueplace",
        "ExtensionContent"=>
        array(
          "InvoiceIssuePlace"=>"MyCity"
        )
      )
    ),
    "UBLVersionID"=>"2.1",
    "ID"=>"01 1206-2406-568",
    ...

这不是我想要的。我需要键中的命名空间。应该更改/添加什么来使SoapClient能够接受请求数组中的键内的命名空间，例如“ext：UBLExtensions”？

Answer 1

我认为您需要在array级而不是UBLExtensions级别开始Invoice。它会将您的顶级元素视为Invoice，预期UBLExtensions并在未找到时抱怨：

SOAP-ERROR: Encoding: object has no 'UBLExtensions' property

它不需要第二个Invoice_attr数组，数组元素的名称取决于模式中的元素名称，而不是ref值。查看ref在您的架构中指向的内容（您似乎没有列出它），element应该有name。

如何在PHP中使用本机SoapClient进行SOAP调用？
