Issue with Python/Zeep script to access CUCM PAWS using the wsdl.

[mb2855]

Hi All,

I am trying to retrieve information from my CUCM clusters via PAWS concerning node status and replication status for each node and the cluster as a whole.

The request works fine in SOAPUI (once I enabled WS-Addressing), and I have a Python script using the Requests library alone that also works. However, in trying to incorporate everything into a Python script using the Requests library, Zeep library, and the PAWS WSDL link, I continually get the following error when I call the 'getClusterStatus' method.

requests.exceptions.SSLError: HTTPSConnectionPool(host='10.x.x.x', port=8080): Max retries exceeded with url: /platform-services/services/ClusterNodesService.ClusterNodesServiceHttpsSoap11Endpoint/ (Caused by SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:997)')))

Thanks for any assistance you may provide.

The code is attached.

At least in some versions, the PAWS WSDLs have the incorrect service port definition, specifying 8080 instead of the actual 8443:

You should be able to work around that at run time by using Zeep's Client.create_service() method, e.g. something like:

service = client.create_service( '{http://services.api.platform.vos.cisco.com}ClusterNodesServiceHttpBinding',
f'https://{os.getenv("CUCM_ADDRESS")}:8443/platform-services/services/ClusterNodesService.ClusterNodesServiceHttpsEndpoint/' )

Thanks dstaudt.
Following your example I had to make a small change to get it to work.

See BOLDed parts that I changed.

service1 = client.create_service( '{http://services.api.platform.vos.cisco.com}ClusterNodesServiceSoap12Binding',

f'https://{node_ip}:8443/platform-services/services/ClusterNodesService.ClusterNodesServiceHttpsSoap12Endpoint/' )
