php - 使用带有 XML 主体的 PHP 创建 SOAP 调用

Question

我正在尝试使用 PHP 调用 SOAP 方法。

这是我得到的代码:

$data = array('Acquirer' =>
  array(
    'Id' => 'MyId',
    'UserId' => 'MyUserId',
    'Password' => 'MyPassword'
  ));
$method = 'Echo';
$client = new SoapClient(NULL,
           array('location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler', 
           'uri' => 'http://example.com/wsdl', 'trace' => 1));
$result = $client->$method($data);

这是它创建的请求:

  <?xml version="1.0" encoding="UTF-8"?>
  <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://example.com/wsdl" xmlns:ns2="http://xml.apache.org/xml-soap" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <SOAP-ENV:Body>
      <ns1:Echo>
        <param0 xsi:type="ns2:Map">
          <item>
            <key xsi:type="xsd:string">Acquirer</key>
            <value xsi:type="ns2:Map">
              <item>
                <key xsi:type="xsd:string">Id</key>
                <value xsi:type="xsd:string">mcp</value>
              </item>
              <item>
                <key xsi:type="xsd:string">UserId</key>
                <value xsi:type="xsd:string">tst001</value>
              </item>
              <item>
                <key xsi:type="xsd:string">Password</key>
                <value xsi:type="xsd:string">test</value>
              </item>
            </value>
          </item>
        </param0>
      </ns1:Echo>
    </SOAP-ENV:Body>
  </SOAP-ENV:Envelope>

这就是我想要请求的样子:

  <?xml version="1.0" encoding="UTF-8"?>
  <SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://example.com/wsdl" xmlns:ns2="http://xml.apache.org/xml-soap" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <SOAP-ENV:Body>
      <Echo>
        <Acquirer>
          <Id>MyId</Id>
          <UserId>MyUserId</UserId>
          <Password>MyPassword</Password>
        </Acquirer>
      </Echo>
    </SOAP-ENV:Body>
  </SOAP-ENV:Envelope>

有几种方法可以解决这个问题。最少的 hackiest 和几乎你想要的:

$client = new SoapClient(
    null,
    array(
        'location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler',
        'uri' => 'http://example.com/wsdl',
        'trace' => 1,
        'use' => SOAP_LITERAL,
    )
);
$params = new \SoapVar("<Acquirer><Id>MyId</Id><UserId>MyUserId</UserId><Password>MyPassword</Password></Acquirer>", XSD_ANYXML);
$result = $client->Echo($params);

这将为您提供以下 XML:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://example.com/wsdl">
    <SOAP-ENV:Body>
        <ns1:Echo>
            <Acquirer>
                <Id>MyId</Id>
                <UserId>MyUserId</UserId>
                <Password>MyPassword</Password>
            </Acquirer>
        </ns1:Echo>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

这几乎正是您想要的，除了方法名称上的命名空间。我不知道这是否是个问题。如果是这样，您可以进一步破解它。你可以把 <Echo>手动标记 XML 字符串，并通过添加 'style' => SOAP_DOCUMENT, 使 SoapClient 不设置方法像这样的选项数组:

$client = new SoapClient(
    null,
    array(
        'location' => 'https://example.com/ExampleWebServiceDL/services/ExampleHandler',
        'uri' => 'http://example.com/wsdl',
        'trace' => 1,
        'use' => SOAP_LITERAL,
        'style' => SOAP_DOCUMENT,
    )
);
$params = new \SoapVar("<Echo><Acquirer><Id>MyId</Id><UserId>MyUserId</UserId><Password>MyPassword</Password></Acquirer></Echo>", XSD_ANYXML);
$result = $client->MethodNameIsIgnored($params);

这会产生以下请求 XML:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body>
        <Echo>
            <Acquirer>
                <Id>MyId</Id>
                <UserId>MyUserId</UserId>
                <Password>MyPassword</Password>
            </Acquirer>
        </Echo>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

最后，如果您想使用 SoapVar 和 SoapParam 对象，您可以在 PHP 手册的评论中找到很好的引用:http://www.php.net/manual/en/soapvar.soapvar.php#104065 .如果你成功了，请告诉我，我失败得很惨。
