Trying to work with the webservice via PHP/SOAP

Hi,

after now I can successfull authenticate a user (Token-ID returns) using PHP/SOAP, I want to work with the Webservices. My first try was get the versions context of a document for download this document. But until now every request failed.

$DocManagementClient = new SoapClient("http://[DOMAIN]/webservice/DocumentManagement.svc?wsdl");
$VersionContext = $DocManagementClient->GetVersion($_SESSION['Token']);

The Session "Token" contains the Token returned from from the Authentication-Process.

But I always get the message that there is an invalid usernamen/password specified or I receive an CGI-Error from the webserver.

After searching the whole morgning in Webservice-Section for a documentation I'm realy tired of it. Can anybody tell me where I can find a good documentation of the webservices or can help me to create the request to download or simply get the version-informations?

Thx
Markus

If you can't get it working on the API level, you could sink to the protocol level and do some investigation there.

I'd dump the SOAP communication of a working test-application in Java or .NET and compare it with the communication done by PHP. Then, with a little bit of luck, isolate th eimportant differences, find out why it is different and make PHP to behave the same way as the working application.

Hi, Markus.

Further to Ferda's comments, you could try compiling and running the LLTreeView samples to capture requests. There are different tracing options for Java and .NET that you could use.

For the GetVersion call, There should be parameters for the Node ID and the version number, which I don't see in your PHP code. Perhaps the token is being passed as the parameter for ID or something like that? That would explain the username/password error, if the token was interpreted as a method parameter.

Thanks,

Hi all,

thanks for help.

I have viewed the TreeView C# Projekt. Now I can see a little bit clearer what parameters wanted.

But it is not 100% clear. For example I try to use "GetVersionContentsContext" to work with its result for downloading a document (found also at the forum). I see that there the ID and VersionNum must be given but also the Token.

From the authentication I know that the data must be send as an array (Name=>Value) but this doesn't work.

*******

  $AuthClient = new SoapClient(http://[DOMAIN]/webservice/Authentication.svc?wsdl);
  $AuthToken = $AuthClient->AuthenticateUser(array('userName'=>'MYUSERNAME','userPassword'=>'MYPASSWORD'));


$DocManagementClient = new SoapClient("http://[DOMAIN]/webservice/DocumentManagement.svc?wsdl");

var $AuthTokenString = $AuthToken->AuthenticateUserResult;

$VersionContext = $DocManagementClient->GetVersionContentsContext(array('OTAuthentication'=>$AuthTokenString,'ID'=>'707935','versionNum'=>'0'));

Hi, Markus.

Your question is about your PHP SoapClient, which I don't think we can help with.

That said, we can help with questions about the web services themselves. Can you elaborate on how the request is not working? Can you send the request itself? By request I mean the actual SOAP request that is sent across the wire.

Also, since OTAuthentication is a SOAP header, maybe there's a different mechanism for setting it in your SoapClient object?

Thanks,

Scott

Hi,

the only problem ist that the webservice don't accept the token which I received from the authentication. Maybe this is the only hurdle I have to take but I don't know how I have to pass it. Strings and Integers (wanted by

Doesn't anyone knows how the token should be send?

Hi, Markus.

The authentication token should be passed as the value for the AuthenticationToken element of the OTAuthentication header.

In the case of a WCF proxy, the header is passed as the first parameter to the method call.

In the case of a JAX-WS proxy, the header can be set using the binding provider or using a SoapHandler (and perhaps other ways as well).

In the case of your PHP SoapClient, I'm afraid I'm not familiar with that tool. Perhaps this site will help? http://php.net/manual/en/soapclient.setsoapheaders.php

Thanks,

The authToken has to be placed in the header of the soap request, NOT the body.

Try to find out if you can add a soapheader entry named 'OTAuthentication' with a subEntry called 'AuthenticationToken', this will have the authToken as value.
In the end, the whole (raw xml)request should look something like this:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Header>
            <h:OTAuthentication xmlns:h="urn:api.ecm.opentext.com" xmlns="urn:api.ecm.opentext.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
                  <AuthenticationToken>blajoabjaopwebjapio2j3pijgbp</AuthenticationToken>
            </h:OTAuthentication>
    </s:Header>
    <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <GetSessionExpirationDate xmlns="urn:Core.service.livelink.opentext.com" />
    </s:Body>
</s:Envelope>

Depending on what soap client you use, it should automaticly add the namespaces('h', 's', 'urn', etc)

Good luck

Hi,

Has anyone actually managed to get this to work and would be able to share a working example?

We are attempting to replicate this in Adobe Coldfusion > Livelink and can authenticate and receive an authentication token but can't progress to return any data which requires the OTAuthorisation token

AxisFault faultCode: {urn:Core.service.livelink.opentext.com}Core.LoginFailed faultSubcode: faultString: Invalid username/password specified.

The username and password are valid and receive a token.

Many thanks

Dave

I’ve never worked with this implementation, but the invalid username/password is coming from the Content Server and indicates a failed login, even though you’re not trying to login.

This is an indication that Content Server is not receiving the token, the token has been modified, or it’s not where we’re looking for it.

Investigating the SOAP message from this failed request and a successful one (.Net would be the easiest/quickest) will likely show a difference in token handling.

Livelink security settings are worth investigating, but are unlikely the cause (?func=admin.securityvars)

Thanks,

Brad
