使用带有XML主体的PHP创建SOAP调用

问题描述：

我正在尝试使用PHP调用SOAP方法.

I'm trying to call a SOAP method using PHP.

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>

这是我想要的要求，如下所示:

And here's what I want the request to look like:

  <?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>

有两种方法可以解决此问题.骇客程度最低，几乎是您想要的东西:

There are a couple of ways to solve this. The least hackiest and almost what you want:

$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:

This gets you the following 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>

几乎就是您想要的，除了方法名称上的名称空间.我不知道这是不是一个问题.如果是这样，您甚至可以进一步破解它.您可以手动将<Echo>标记放入XML字符串中，并让SoapClient不通过将'style' => SOAP_DOCUMENT,添加到options数组中来设置方法，如下所示:

That is almost exactly what you want, except for the namespace on the method name. I don't know if this is a problem. If so, you can hack it even further. You could put the <Echo> tag in the XML string by hand and have the SoapClient not set the method by adding 'style' => SOAP_DOCUMENT, to the options array like this:

$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);

这将导致以下请求XML:

This results in the following request 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，可以在PHP手册的此注释中找到一个很好的参考:

Finally, if you want to play around with SoapVar and SoapParam objects, you can find a good reference in this comment in the PHP manual: http://www.php.net/manual/en/soapvar.soapvar.php#104065. If you get that to work, please let me know, I failed miserably.
