PHP中的C＃NetworkCredential

Question

I am trying to access a webservice through PHP. The webservice returns a byte array with a jpeg image, which is then shown on a webpage.

Today the service is accesses by a C# call, like so

ImgService i = new ImgService();

The credentials are set like this:

i.Credentials = new System.Net.NetworkCredential(username, password, domain);

Access to webservice:

byte[] result = null;

result = i.GetThumbNail(raceId, startNum, seasonId, height, width, true);
Response.ContentType = "image/jpeg";
Response.BinaryWrite(result);

The service is working fine in C# but now I need to access it through PHP and the only image I am getting is "missing.jpg". I am not sure if this means that the credentials are wrong or if something else is wrong, but I feel very unsure about the credentials part.

This is the PHP code without any credentials:

$client = new SoapClient("http://www.example.com/imgService.asmx?WSDL");
$result = $client->GetThumbNail($args['race'], $args['startnumber'], $args['year'], 0, 0, true);
$image_data = $result->GetThumbNailResult;
echo '<img src="data:image/jpeg;base64,'.base64_encode($image_data).'">';

I have also tried using calls like this:

$headers = array(
                            'username'  =>  'user',
                            'password'  =>  'pass',
                            'domain'    =>  'domain'
                            );
$header = new SoapHeader("http://tempuri.org/", 'UserCredentials', $headers, false);
$client->__setSoapHeaders($header);
$result = $client->GetThumbNail(parameters);

Both versions gives me the same missing.jpg and no error message. I feel I would get an error if the service did not accept the call?

Did not manage to solve this problem with the old web service, so I ended up creating a new HttpHandler doing the same thing the old service did. Oh well...
