Issue Calling VCO workflow from Python script

[APJ_vm]

Hi

I am trying to call a VCO workflow from a python script on a ESXi 6.0 host. Hopefully this is the most appropriate forum. The below script works if I run it from a python install on my laptop. The expected out put is meant to be a listing of the Configure Mail workflow.

#! /bin/python
import urllib2
import base64
import ssl
import xml
from urlparse import urlparse


vroServer = '192.168.199.6:8281'
print vroServer
theurl = 'https://' + vroServer + '/vco/api/workflows/?conditions=name=Configure%20mail'
print theurl
username = 'vcoadmin@vsphere.local'
password = 'vcoadmin'

context = ssl.CERT_NONE
ssl._create_default_https_context = ssl._create_unverified_context

req = urllib2.Request(theurl)
print req
base64string = base64.encodestring('%s:%s' % (username, password))[:-1]
authheader =  "Basic %s" % base64string
req.add_header('User-agent', 'Mozilla/5.0')
req.add_header('Content-Type','application/xml')
req.add_header('Accept','application/xml')
req.add_header('Authorization', authheader)
print req
handle = urllib2.urlopen(req)
thepage = handle.read()
print thepage

The output I get is below

Traceback (most recent call last):
  File "./VCOTest.py", line 28, in <module>
    handle = urllib2.urlopen(req)

Thanks .

Looks like a network setup issue.

Check if there is a proxy/firewall installed. Also, verify that the network port is open.

BTW, the default username (assuming you haven't changed vCO authentication configuration) is just vcoadmin, not vcoadmin@vsphere.local.

This is just a test lab so there is no firewall or proxy involved. The python script I am trying to use works from a windows machine just not from my ESXi host. And my python skills are limited at best so not sure how or where to start troubleshooting. Maybe a tcmdump might show more info

So I figured it out after you mentioned firewall. I completely forgot about the firewall on the ESXi host itself. I just had to create a custom firewall rule and then I was able to call my VCO workflow.
