Error while invoking selectCmDeviceExt API

dilipreddy.guda — Tue, 20 Feb 2018 13:11:02 GMT

I am running into below issue while invoking "selectCmDeviceExt" API.

The idea is to fetch phone details whose model number is 688 (i.e. SX-80 devices)

code snippet :

SRV_CMSERVER='X.X.X.X' #PUB IP of SIN CUCM cluster

SRV_axl_port='8443'

SRV_user='appadmin'

SRV_passwd='XXXXXXX'

SRV_wsdl='https://'+SRV_CMSERVER+':'+SRV_axl_port+'/realtimeservice2/services/RISService70?wsdl'

SRV_location='https://'+SRV_CMSERVER+':'+SRV_axl_port+'/realtimeservice2/services/RISService70'

t = HttpAuthenticated(username='dilipreddy.guda', password='XXXXXXXX')

t.handler=urllib.request.HTTPBasicAuthHandler(t.pm)

ssl_def_context = ssl.create_default_context()

ssl_def_context.check_hostname = False

ssl_def_context.verify_mode = ssl.CERT_NONE

t1=urllib.request.HTTPSHandler(context=ssl_def_context)

t.urlopener = urllib.request.build_opener(t.handler,t1)

tns = 'http://schemas.cisco.com/ast/soap/'

imp = Import('http://schemas.xmlsoap.org/soap/encoding/', 'http://schemas.xmlsoap.org/soap/encoding/')

imp.filter.add(tns)

client=Client(SRV_wsdl,location=SRV_location,plugins=[ImportDoctor(imp)],transport=t)

result = client.service.selectCmDeviceExt('',{'SelectBy':'Name', 'Status':'Any', 'Class':'Phone', 'Model':'688', 'MaxReturnedDevices' : '1000'}) -- > This is where error is observed.

If I use "selectCmDevice" API with below WSDL then the API works fine. But the problem here is there is no "selectCmDeviceExt" API in this wsdl . Want to use "selectCmDeviceExt" API as this This request consolidates device records across nodes, returning only the device info for the latest registration.

SRV_wsdl='https://'+SRV_CMSERVER+':'+SRV_axl_port+'/realtimeservice/services/RisPort?wsdl'

SRV_location='https://'+SRV_CMSERVER+':'+SRV_axl_port+'/realtimeservice/services/RisPort'

result = client.service.SelectCmDevice('',{'SelectBy':'Name', 'Status':'Any', 'Class':'Phone', 'Model':'688', 'MaxReturnedDevices' : '1000'})

Would appreciate your help to resolve this issue. Let me know if any further details are required.

Looks like I was able to get it working with this code:

# Installing a root/CA Certificate
# (Tested on Ubuntu 16.10, 17.10)

# Retrieve certificate from CUCM
#    - openssl s_client -showcerts -connect cucm-node.example.com:443 </dev/null 2>/dev/null|openssl x509 >cucm-node.example.com.crt
# Store certificate on the client
#    - Create a directory for extra CA certificates in /usr/share/ca-certificates:
#        sudo mkdir /usr/share/ca-certificates/extra
#    - Copy the CA .crt file to this directory:
#        sudo cp foo.crt /usr/share/ca-certificates/extra/foo.crt
#    - Append the certificate path (relative to /usr/share/ca-certificates) to /etc/ca-certificates.conf
#        sudo dpkg-reconfigure ca-certificates

# In case of a .pem file, it must first be converted to a .crt file:
#    openssl x509 -in foo.pem -inform PEM -out foo.crt

from suds.client import Client

# import logging

# logging.basicConfig(level=logging.INFO)
# logging.getLogger("suds.transport").setLevel(logging.DEBUG)

client = Client("file:////home/dstaudt/Documents/Serviceability/v10.5(1)/RISService70.wsdl",
    location="https://ds-ucm105.cisco.com:8443/realtimeservice2/services/RISService70",
    username="Administrator",
    password="ciscopsdt")

CmSelectionCriteria = {
    "MaxReturnedDevices": "1000",
    "DeviceClass": "Phone",
    "Model": 30016,
    "Status": "Any",
    "NodeName": "",
    "SelectBy": "Name",
    "SelectItems": {
        "item": {
            "Item": "*"
        }
    },
    "Protocol": "Any",
    "DownloadStatus": "Any"
}

result = client.service.selectCmDevice("",CmSelectionCriteria)
print(result)

Note, I found this little sample, which helps you inspect the object schema created when the WSDL is imported by suds-jurko:

import sys, getopt
from suds.client import Client

def getAvailableMethods(client):
    methods = [method for method in client.wsdl.services[0].ports[0].methods]
    return methods

def printAvailableMethods(method_names):
    print("These are all the methods available: ")
    for method_name in method_names:
        param_names = getMethodParams(method_name)
        sys.stdout.write(" * " + method_name + ": ")
        for param_name in param_names:
            sys.stdout.write(param_name + " ")
        sys.stdout.write("\n")

def callSampleMethods(method_names):
    print("Calling all methods that don't need any parameters.")
    for method_name in method_names:
        if len(getMethodParams(method_name)) == 0:
            print(" * " + method_name)
            result = getattr(client.service, method_name)()
            print(result)

def getMethodParams(method_name):
    method = client.wsdl.services[0].ports[0].methods[method_name]
    params = method.binding.input.param_defs(method)
    param_names = []
    for param in params:
        param_names.append(param[0])
    return param_names

if __name__ == "__main__":

    # Start a client and point to the WSDL URL
    client = Client("file:////home/dstaudt/Documents/Serviceability/v10.5(1)/RISService70.wsdl",
        location="https://ds-ucm105.cisco.com:8443/realtimeservice2/services/RISService70",
        username="Administrator",
        password="ciscopsdt")
    print(client)

    # Get some info from available funtionality
    availableMethods = getAvailableMethods(client)
    printAvailableMethods(availableMethods)
    # callSampleMethods(availableMethods)
