PowerShell SOAP Request answered with "error.validation.required"

[ruben.zimmermann]

Hi,

I am trying to retrieve the backup progress via SOAP in PowerShell.

Here my code:

$serverURL = 'https://auc521/platform-services/services/MaintenanceService?wsdl'

$soapRequest = [xml]@"
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.api.platform.vos.cisco.com">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:getBackupProgress/>
   </soapenv:Body>
</soapenv:Envelope>
"@

$ciscoUser = 'admin'

$ciscoPwd = 'UC123456!'

$header = @{"Authorization" = "Basic "+[System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($ciscoUser+":"+$ciscoPwd))}

$result = Invoke-WebRequest -Uri $serverURL -Headers $header -Method Post -Body $soapRequest -ContentType "text/xml"

$SOAP = $result.Content

$SOAP | Out-File -FilePath $logFile

The response I get is the following:

<?xml version='1.0' encoding='UTF-8'?>

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

  <soapenv:Body>

    <ns:getBackupProgressResponse xmlns:ns="http://services.api.platform.vos.cisco.com">

      <ns:return xmlns:ax214="http://api.platform.vos.cisco.com/xsd" xmlns:ax213="http://element.services.api.platform.vos.cisco.com/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ax213:MaintenanceResponse">

        <ax213:remoteMessages xsi:type="ax213:RemoteMessage">

          <ax214:error>true</ax214:error>

          <ax214:info>false</ax214:info>

          <ax214:messageKey>error.validation.required</ax214:messageKey>

          <ax214:messageType>internal.message.error</ax214:messageType>

          <ax214:warning>false</ax214:warning>

          <ax213:messageParams>wsa.replyto</ax213:messageParams>

        </ax213:remoteMessages>

        <ax213:result>internal.request.failed</ax213:result>

        <ax213:backupProgressResult xsi:nil="true" />

        <ax213:startBackupResult xsi:nil="true" />

        <ax213:updateScheduleResult xsi:nil="true" />

      </ns:return>

    </ns:getBackupProgressResponse>

  </soapenv:Body>

</soapenv:Envelope>

Can you please help me to fix it?

Thanks in advance

Ruben

It looks like the WS-Addressing info (which is required for PAWS requests) has not been included in the request XML.  See the developer guide for more details: https://developer.cisco.com/site/paws/documents/api-reference/#web-service-addressing

This request seems to work on my 10.5 lab system:

Thank you for the fast feedback :-)

I exchanged the variable content as suggested. My lines look as follows:

$soapRequest = [xml]@"

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ser="http://services.api.platform.vos.cisco.com"> 

  <soap:Header xmlns:wsa="http://www.w3.org/2005/08/addressing"> 

    <wsa:Action>urn:getBackupProgress</wsa:Action> 

    <wsa:ReplyTo> 

      <wsa:Address>http://www.w3.org/2005/08/addressing/anonymous</wsa:Address> 

    </wsa:ReplyTo> 

    <wsa:MessageID>uuid:dc75e529-34fb-4009-b594-d801ec86f39e</wsa:MessageID> 

  </soap:Header> 

  <soap:Body> 

    <ser:getBackupProgress/> 

  </soap:Body> 

</soap:Envelope> 

"@

The response I get is: The remote server returned an error: (500) Internal Server Error.

The XML portion seems to work copy/pasting and executing with soapUI for me against CUCM 10.5:

- Are you able to successful do a similar request using another tool (soapUI) or mechanism?

- Can you confirm the PAWS service is enabled on CUCM? Getting Started

- Can you capture the raw HTTP request, either somehow via power tools script, or by using something like Fiddler2?

[ruben.zimmermann]

Just downloaded Fiddler2 and could enable the SSL decryption! - Great hint! :-)

Here is the TextView:

<?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing"><wsa:Action>http://www.w3.org/2005/08/addressing/soap/fault</wsa:Action></soapenv:Header><soapenv:Body><soapenv:Fault><faultcode>soapenv:VersionMismatch</faultcode><faultstring>Transport level information does not match with SOAP Message namespace URI</faultstring><detail><Exception>org.apache.axis2.AxisFault: Transport level information does not match with SOAP Message namespace URI

   ...

</Exception></detail></soapenv:Fault></soapenv:Body></soapenv:Envelope>

Found than that changing the content type to: application/soap+xml works!!!

Thank you very much!

Kind regards
