how to get a session token in a discovery pattern for REST discovery

[RolandW1]

I would like to discover the HPE Oneview Global Dashboard appliance to retrieve hardware information using the REST API.

I need to get an authorization session token but I am unsure if this is possible using the OOTB pattern steps. Or how else this could be accomplished. I could not find any good documentation on this subject.

https://servername/rest/login-sessions/

To get a  token I need to send this:

Content-Type: Specifies the content type of the request body and should be set to application/json.
X-Api-Version: integer [ 2 .. 300 ] Required

I can query the version needed with the following url:

https://servername/rest/version 

which returns:

{

"minimumVersion": 2,
"currentVersion": 300

}

The request body should contain the following:

{

"authLoginDomain": "local",
"password": "secret",
"userName": "sarah"

}

I need to get an answer like this:

{

"token": "NTAxMjQzNDc2NzIyR2yWViDr0ENEJvM1cu7IJap7h_UmkDSj",
"user":

{

"domain": "local",
"user_roles":

[],
"userName": "administrator"

}

I need the token to be able to query the data from the appliance.

What kind of pattern step(s) can I use to accomplish this? I could not find an example in the OOTB patterns.

Can we use "basic authentication credentials here without hardcoding them?

Any help will be greatly appreciated!

Best regards,

Roland

Hi Roland,

Create a custom pattern operation (sa_custom_operation) where you can write scripts. Once it's been created you can use them in your patterns. You can have a look at the existing examples in that table for reference.

Hi Vivek,

Thanks, I have looked at that but could not find a good example. I am not a scripting god so maybe I overlooked it. Do you have the name/specific example from the existing examples? I don't see any doing something with posting for a session token?

Best regards,

Roland

I know this is an old thread but... still trying to get a Pattern for our newer HPE Synergy gear that now uses REST API unlike the really old stuff that the ServiceNow Discovery Pattern is for...

Have a Custom Operation written, but...

End up with an issue with scopes

Script calls RESTmessageV2 which is scoped sn_ws

     var restMessage = new sn_ws.RESTMessageV2();
     ....

When called in the Discovery Pattern returns an error = sn.ws is not defined
