Attached is an example of Python script that calls UCSD northbound Web Services API. This has been tested with Python 2.7 and UCSD 5.2. The example show how to execute a Workflow in UCSD.

Here is the Script:

import urllib2

import json

import time

ip_addr = "10.95.4.23"

username = "admin"

password = "admin"

workflowName = "DeployESXi"

def getApiKey (ip_addr, username, password):

    ip_addr = ip_addr

    username = username

    password = password

   

    url = 'http://'+ip_addr+'/app/api/rest?formatType=json&opName=getRESTKey&user='+username+'&password='+password

    # This packages the request (it doesn't make it)

    request = urllib2.Request(url=url)

    # Sends the request and catches the response

    response = urllib2.urlopen(request)

   

    return response.read().replace("\"", "")

apiKey = getApiKey(ip_addr, username, password)

url = 'http://'+ip_addr+'/app/api/rest?formatType=json&opName=userAPIGetMyLoginProfile&opData={}'

# This packages the request (it doesn't make it)

request = urllib2.Request(url=url, headers={"X-Cloupia-Request-Key" : apiKey})

# Sends the request and catches the response

response = urllib2.urlopen(request)

   

print response.read()

#######Execute a workflow#######

url = 'http://'+ip_addr+'/app/api/rest?formatType=json&opName=userAPISubmitWorkflowServiceRequest&opData={param0:"DeployESXi",param1:{"list":[{"name":"Hostname","value":"Nike"}]},param2:-1}'

request = urllib2.Request(url=url, headers={"X-Cloupia-Request-Key" : apiKey})

response = urllib2.urlopen(request)

j = json.loads(response.read())

serviceRequest = j['serviceResult']

print serviceRequest

######Check for completion######

flag = 0

while flag == 0:

    time.sleep(30)

    url = 'http://'+ip_addr+'/app/api/rest?formatType=json&opName=userAPIGetWorkflowStatus&opData={param0:'+str(serviceRequest)+'}'

    request = urllib2.Request(url=url, headers={"X-Cloupia-Request-Key" : apiKey})

    response = urllib2.urlopen(request)

    j = json.loads(response.read())

    status = j['serviceResult']

    if status == 1:

        print "Workflow "+workflowName+" with SR ID "+str(serviceRequest)+" is In Progress"

    elif status == 3:

        print "Workflow "+workflowName+" with SR ID "+str(serviceRequest)+" is Complete"

        flag = 1

    elif status == 2:

        print "Workflow "+workflowName+" with SR ID "+str(serviceRequest)+" Failed"

        flag = 1
