External webservice "Internal Error" - web-services

Question

Okey so after searching for 3 hours and trying various options, I no longer have any clue how to solve this...
The situation:
Our nationwide packet deliverer (Die Post) offers a webservice for checking if an address exists.
I contacted them, received username and password for the application as well as the .wsdl-file.
I made a service reference to the downloaded file and can use the classes without problems.
Now the problem:
We have 2 other webservices which the previous programer set up with authentication and everything, I just copy pasted the code from one of the services and set everything to current one, but when I try to get a response, I always get an error (Internal Error), with no more information.
I found a way to get the last request and the only difference from the request to the one in the SoapUI (which works perfectly fine) is that, instead of "<soapenv:Header/>" it is
<s:Header>
<Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://post.ch/AdressCheckerExtern/V4-01-00</Action>
</s:Header>
The current code is:
// Create Request
PostAdressChecker.AdressCheckerRequestType adrRequest = new PostAdressChecker.AdressCheckerRequestType()
{
Street = strStrasse,
HouseNbr = strHausnummer,
Zip = strPlz,
Town = strOrt,
Params = new PostAdressChecker.AdressCheckerRequestTypeParams()
{
CallUser = "TU_99660_0001",
SearchLanguage = "1",
MaxRows = "10",
SearchType = "10"
}
};
BasicHttpBinding basicBinding = new BasicHttpBinding(BasicHttpSecurityMode.Transport)
{
ReaderQuotas = { MaxStringContentLength = int.MaxValue },
MaxReceivedMessageSize = int.MaxValue,
SendTimeout = new TimeSpan(0, 2, 0)
};
PostAdressChecker.ACHePortTypeClient client;
client = new PostAdressChecker.ACHePortTypeClient(basicBinding, new EndpointAddress(strUrl));
client.Endpoint.Behaviors.Add(new PostSigningEndpointBehavior(strUsername, strPassword));
SoapTracer RequestInterceptor = new SoapTracer();
client.Endpoint.Behaviors.Add(RequestInterceptor);
try
{
PostAdressChecker.AdressCheckerResponseType adrResponse = client.AdrCheckerExterne(adrRequest);
}
catch (Exception ex)
{
strError = ex.ToString();
}
Does anybody have an idea how to debug/solve this?
Thank you very much and best regards

Answer 1

in perl I do it like this. maybe this can give you some inspiration ...
sub clientFactory {
my $wsdl = XML::Compile::WSDL11->new('etc/adrCheckerExterne-V4-01-00.wsdl');
$wsdl->importDefinitions('etc/adrCheckerExterne-V4-01-00.xsd');
$wsdl->importDefinitions('etc/adrCheckerTypes-V4-01-00.xsd');
my $basic_auth = sub {
my ($request, $trace) = #_;
my $authorization = 'Basic '.
b64_encode "$adrCheckerUser:$adrCheckerPassword";
$request->header(Authorization => $authorization );
my $ua = $trace->{user_agent};
$ua->request($request);
};
return $wsdl->compileClient(
'AdrCheckerExterne',
transport_hook => $basic_auth,
aync => 1,
);
};
my $client = clientFactory;
my $check = $client->(
Params => {
MaxRows => 100,
CallUser => $adrCheckerUser,
SearchLanguage => 1,
SearchType => 1
},
FirstName => $first_name,
Name => ${last_name},
Street => ${street},
HouseNbr => ${nr},
Zip => ${zip},
Town => ${town},
HouseKey => 0,
PboxAddress => 0,
);

Answer 2

You need to add HouseKey = 0 to your adrRequest. This is a required input - you can just set it to 0 if you do not know it. Otherwise the service will return an error.
