从PHP SOAP或nusoap向.NET服务发送XML字符串（不是数组）

I'm new to SOAP and I'm having issues (yes, I have searched - extensively, but I can't seem to match my very simple requirement - sending a single XML string) with sending some output to a .NET server to match this:

    POST /someurl.asmx HTTP/1.1
Host: www.somehost.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://somehost.com/SubmitCalls"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <SubmitCalls xmlns="http://somehost/">
      <request>string</request>
    </SubmitCalls>
  </soap:Body>
</soap:Envelope>

My nusoap code looks like this:

<?php
require_once('../lib/nusoap.php');

$bodyxml = '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<SubmitCalls xmlns="http://somehost/" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<request>
<?xml version="1.0" encoding="UTF-8"?>
<bXML xmlns="http://somehost/Schemas" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 <From>
  <UserName>some username</UserName>
  <Password>some password</Password>

';


$client = new nusoap_client("somehost?WSDL",true);
$err = $client->getError();
if ($err) {
 echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
 exit();
}

$client->soap_defencoding = 'utf-8';
$client->useHTTPPersistentConnection();
$client->setUseCurl($useCURL);
$bsoapaction = "http://somehost/SubmitCalls";
$result = $client->send($bodyxml, $bsoapaction);
// Check for a fault
if ($client->fault) {
 echo '<h2>Fault</h2><pre>';
 print_r($result);
 echo '</pre>';
} else {
 // Check for errors
 $err = $client->getError();
 if ($err) {
  // Display the error
  echo '<h2>Error</h2><pre>' . $err . '</pre>';
 } else {
  // Display the result
  echo '<h2>Result</h2><pre>';
  print_r($result);
  echo '</pre>';
 }
}
echo '<h2>Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';
echo '<h2>Response</h2><pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';
echo '<h2>Client Debug</h2><pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';
echo '<h2>Proxy Debug</h2><pre>' . htmlspecialchars($proxy->debug_str, ENT_QUOTES) . '</pre>';
?>

(Obiously, all the somehost and usernames are correct in the final script). I can connect to the WSDL, read it, there's only one method I'm interested in (SubmitCalls) which only has one part, named 'parameters' in the WSDL schema. The above throws a 400 Bad request error - any ideas where I'm going wrong?

I've tried using PHP SOAP instead, but I simply can't seem to send an XML string as the body of the SOAP request. I've been fiddling with this for the best part of three days and read a zillion web pages, but I still can't get it right. Please help.... if you could show me how to do this using either library I would be enormously grateful....

You can always just send the xml as a string and screw the libraries. Not recommended but in some cases that is easier.

don't forget the Header("SoapAction: ...")

Not exactly an answer to the issue - but it is now solved. The service provider created a new method, which was identical in all respects except that it allowed for an XML document rather than a string. By making some minor alterations to the contents of the $bodyxml variable, and sending to this new method, it appears to work fine.

By the way - anyone looking to debug SOAP applications should really look at grabbing SOAP UI off Sourceforge. This really helped me sanity check my issue, and provided some useful pointers for the fix.

-try this-

$xml = simplexml_load_string('<data>x</data>')

and then (nusoap)

$result = $client->call('host', array('parameter' =>$xml)

You can send plain XML with the $client->send() method.

$raw_xml = "<Your_XML>...</Your_XML>";
$msg = $client->serializeEnvelope("$raw_xml");
$result=$client->send($msg, $endpoint);

You can see the example here:

If that does't work you can try posting the XML with CURL.
