创建不带WSDL文件的PHP SOAP请求（Flickr SOAP API）

Question

I' trying to create a request for the Flickr SOAP API, but can't get the correct format. Here is the XML they want sent.:

    <s:Envelope
    xmlns:s="http://www.w3.org/2003/05/soap-envelope"
    xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/1999/XMLSchema"
>
    <s:Body>
        <x:FlickrRequest xmlns:x="urn:flickr">
            <method>flickr.test.echo</method>
            <name>value</name>
        </x:FlickrRequest>
    </s:Body>
</s:Envelope>

Here is my code:

<?php
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
$opts = array('location' => 'http://api.flickr.com/services/soap/',
              'uri'      => 'urn:flickr',
              'trace'    => 1
);
$client = new SOAPClient(null, $opts);
?>

    <?php
      try {

        $data = $client->__soapCall('flickr.test.echo', array('name'));
        print_r($data);

      } catch (SoapFault $exception) {

        echo 'Exception Thrown: '.$exception->faultstring.'<br><br>';  

      print "<pre>\n";
      print "Request :\n".htmlspecialchars($client->__getLastRequest()) ."\n";
      print "Response:\n".htmlspecialchars($client->__getLastResponse())."\n";
      print "</pre>";   

      }

    ?>

Here is the response:

Exception Thrown: 

Request :
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"

<param0 xsi:type="xsd:string">name</param0>
</ns1:flickr.test.echo>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Response:
<?xml version="1.0" encoding="utf-8" ?>
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope">
    <s:Body>
        <s:Fault>
            <faultcode>flickr.error.0</faultcode>
            <faultstring>Invalid SOAP envelope.</faultstring>
            <faultactor>http://www.flickr.com/services/soap/</faultactor>
            <details>Please see http://www.flickr.com/services/api/ for more details</details>
        </s:Fault>
    </s:Body>
</s:Envelope>

Unfortunately Flickr does not provide a WSDL file.

thanks

<< ** UPDATE ** >> I'm getting closer. I changed my code and it's almost to where it's supposed to be:

<?php
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache

$opts = array('location' => 'http://api.flickr.com/services/soap/',
              'uri'      => 'http://api.flickr.com/services/soap/',
              'trace'    => 1
);
$client = new SOAPClient(null, $opts);
?>
<?php
  try {

    $data = $client->__soapCall("FlickrRequest",
       array(new SoapParam('flickr.test.echo', 'method'), new SoapParam('value', 'name')),
       array('soapaction' => 'http://api.flickr.com/services/soap/')
    );  
    print_r($data);


  } catch (SoapFault $exception) {

    echo 'Exception Thrown:  '.$exception->faultstring.'<br><br>';  

  print "<pre>\n";
  print "Request :\n".htmlspecialchars($client->__getLastRequest()) ."\n";
  print "Response:\n".htmlspecialchars($client->__getLastResponse())."\n";
  print "</pre>";   
  }

?>

What's being sent now is:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://api.flickr.com/services/soap/"

SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<ns1:FlickrRequest>
<method xsi:type="xsd:string">flickr.test.echo</method>
<name xsi:type="xsd:string">value</name>
</ns1:FlickrRequest>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

I managed to make it work using this code:

<?php 
    $url = 'https://api.flickr.com/services/soap';

    $xml_post_string = '<s:Envelope
                            xmlns:s="http://www.w3.org/2003/05/soap-envelope"
                            xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
                            xmlns:xsd="http://www.w3.org/1999/XMLSchema"
                        >
                            <s:Body>
                                <x:FlickrRequest xmlns:x="urn:flickr">
                                    <method>flickr.photos.getRecent</method>
                                    <api_key>YOUR_API_KEY</api_key>
                                    <page>1</page>
                                    <per_page>10</per_page>
                                </x:FlickrRequest>
                            </s:Body>
                        </s:Envelope>';

       $headers = array(
                    "Content-type: text/xml;charset=\"utf-8\"",
                    "Accept: text/xml",
                    "Cache-Control: no-cache",
                    "Pragma: no-cache",
                    "Content-length: ".strlen($xml_post_string),
                );

        // PHP cURL
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

        $response = curl_exec($ch);
        curl_close($ch);
?>

The method that I call is flickr.photos.getRecent , and the parameters passed are:

• api_key --> tour api key
• page --> the page targeted
• per_page --> the number of elements per page

Here is the response:
