Digest Authentication for ROBOTFRAMEWORK - robotframework

Question

below is the begining of a script for testing a rest interface on a device , this device has a https server with Digest Authentication.
This is where i am encountering a problem below I have it set up I do not get an error so i assume
Set Digest Auth admin secret is valid
if it is what can I not authenticate:
#script
*** Settings ***
Resource variablesreal.txt
Library HttpLibrary.HTTP
Library PycURLLibrary
Library OperatingSystem
Test Setup Create HTTP Context ${HOST} https
*** Variables ***
${HEADER1} Content-Type: text/xml; charset=UTF-8
*** Test Cases ***
Set Digest Auth
Log Variables
Verbose
Add Header ${HEADER1}
Add Header version:1
Next Request Should Not Succeed
GET https://${HOST}/views
Set Digest Auth admin secret
GET https://${HOST}/views
Response Status Code Should Equal 200
Response Body Should Contain views
Log Response Status
Log Response
here is the out put from pybot hls.txt

Request should have succeeded, but was "401 Unauthorized".

Answer 1

I ended up adding this to RequestKeywords.py
def create_digest_session(self, alias, url, auth, headers={}, cookies=None, timeout=None, proxies=None, verify=False):
""" Create Session: create a HTTP session to a server
`url` Base url of the server
`alias` Robot Framework alias to identify the session
`headers` Dictionary of default headers
`auth` List of username & password for HTTP Digest Auth
`timeout` connection timeout
`proxies` proxy server url
`verify` set to True if Requests should verify the certificate
"""
digest_auth = requests.auth.HTTPDigestAuth(*auth) if auth else None
return self._create_session_local(alias, url, headers, cookies, digest_auth, timeout, proxies, verify)
