These scripts employ two different Cisco IM&P services. One is EPASSoap
,
obviously a SOAP API. The other is Presence Web Services
(PWS)
,
for which you can use SOAP or REST. The examples here use REST for PWS
.
You can download the documentation from here: (https://developer.cisco.com/site/im-and-presence/documents/presence_web_service/latest_version/)
-
Edit the json and list files to define your server, users, contact, etc. (see
SET YOUR PARAMETERS
below) -
Make sure the computer you're using for the endpoint can accept and respond to TCP port 5000 (generally via firewall settings)
-
Run the endpoint listener web service script
endpoint.py
$ python endpoint.py
- Run the script
pws-create.py
. This tells Cisco IM&P about the endpoint, and subscribes to presence notifications for a contact.
$ python pws-create.py
- Change the presence of the contact you defined in
enduser.json
. You can do this with a Jabber/XMPP client or with the scriptsetpresence.py
$ python setpresence.py <presence, such as AVAILABLE>
These are self-explanatory optional scripts for adding and deleting contacts for the end user. If you already have users and contacts set up to work with, you won't need these scripts.
The API requests to add and delete contacts are only available as SOAP
requests. So addcontacts.py
and delcontacts.py
both use EPASSoap,
not REST.
The API to set up your own presence notification handler is PWS
or
Presence Web Services
. You can use SOAP or REST here, but REST is a
simpler API to work with, so our examples use REST, pws-create.py
,
pws-delete.py
, endpoint.py
and (optional) setpresence.py
.
The REST API procedure is generally as follows:
-
Log in an application user with the username and password. This returns the app user session key
-
Use the app user session key to log in an end user with the end user username, which returns an end user session key
-
Use the session keys to access the API requests you want.
-
Log in the application user and end user.
-
Use the app user session key to specify an endpoint URL. This URL points to the web service that will receive presence notifications.
-
Use the end user session key to subscribe for presence notifications of a list of specified contacts. When the presence for one of these contacts changes, it will trigger a notification sent to the endpoint. It is the responsibility of the web service endpoint to fetch the actual presence status, whether it's BASIC presence or RICH presence.
This script is simply an "undo" for pws-create.py
. It unsubscribes
presence notifications for the contacts and unregisters the endpoint URL.
Use this script to clear the subscriptions and endpoint when you want to change anything and try again.
This is the web service that listens on port 5000 for REST-initiated
notifications that a contact's presence has changed. It responds by
using a REST request to fetch the BASIC presence for that contact,
and appends the presence status response to the file status.txt
.
This project works fine without this script if you want to change
the presence of a contact using any XMPP/Jabber client.
If you don't want to use an XMPP/Jabber client, you can use this script
to change the presence of the contact defined in enduser.json
.
Usage:
python setpresence.py <one of AVAILABLE, BUSY, DND, AWAY, UNAVAILABLE or VACATION>
Install Python 3.7. Follow the instructions for your OS from here: (https://docs.python.org/3.7/using/index.html)
On Windows, choose the option to add to PATH environment variable
While we use the commands pip
and python
in this documentation,
you may need to substitute them with pip3
and possibly python3
on
Linux or Mac.
It is good practice to create and work with a virtual environment. This lets you install a number of Python libraries needed only for your test project, and not necessarily installed in your default Python setup. See this link for instructions on how to set up a virtual environment for your operating system: (https://docs.python.org/3/tutorial/venv.html)
Follow the instructions for entering your virtual environment, and then proceed to install the necessary Python library dependencies for this project.
Once you have your virtual environment installed, execute the correct
activate
procedure for your OS so that you're operating from within
the virtual environment.
The commands you'll need to install dependencies will vary from OS to OS. Start with
$ pip install zeep
This should automatically install most libraries you'll need. If you get
a message when you run a script that says your import
doesn't work,
then try to pip install <that dependency>
.
Script Dependencies:
lxml
requests
zeep
json
The endpoint.py
script needs flask
, so run:
$ pip install flask
- [REQUIRED] Edit
serverparams.json
to point to your Cisco IM&P server and the administrator username and password credentials.
The file also contains the host IP for the endpoint URL. This is the URL for the web service that listens for presence notifications.
The default port for the web service is 5000, so you'll need to make
sure the PC or server running endpoint.py
can accept TCP traffic
over port 5000.
{
"params" : [
{
"SERVER" : "<your cimp server>",
"USERNAME" : "administrator",
"PASSWD" : "password"
"HOST": "<host IP of the ENDPOINTURL>"
}
]
}
- [REQUIRED] Edit
appuser.json
to include the username and password of your application user.
{
"params" : [
{
"USERNAME" : "<Application user name>",
"PASSWD" : "<Application user password>"
}
]
}
- [REQUIRED] Edit
enduser.json
to include the username of the user whose contacts you want to add, and the name of one of that user's contacts.
You want to specify only the user names, not the full JIDs. In other words,
you want joe
not [email protected]
.
The USERNAME
is the name of the end user whose contact's presence you want
to monitor.
The CONTACT
is the name of the user whose presence you want to monitor.
This data is used by the Presence Web Services (PWS) scripts
pws-create.py
, pws-delete.py
, setpresence.py
and endpoint.py
.
{
"params" : [
{
"USERNAME" : "<Jabber end user name>",
"CONTACT" : "<End user contact name you want to monitor for presence>"
}
]
}
- [OPTIONAL] Edit
contacts.list
to include contacts for your end user.
If the contact you specified for your end user already exists in
the end user's "buddy list" or "contacts" (or however your client
refers to contacts), you won't need to use addcontacts.py
.
In case you don't already have contacts for your test user, edit
contacts.list
to include the names of one or more contacts you want
to add (or delete later) with addcontacts.py
and delcontacts.py
.
Make sure one of these contacts is the CONTACT
you specified in
enduser.json
(see above).
For example, if you specified carlotta
as your CONTACT
, you'll want
carlotta
in the list:
[ "carlotta", "reed", "joe" ]
All contacts go into a group called Contacts
. This is hard coded
in the scripts, so you'd have to change the scripts to change that
group to another group name. This shouldn't be necessary for the
scripts to work.
If you're using the contacts only for testing purposes, you can remove
them when you're done with the script delcontacts.py
.
