$RequesterCloudUserID

$RequesterCloudUserID

gives the cloud user ID of the authenticated user requesting the current evaluation.

Details

  • If the current evaluation was not initiated by an authenticated user, $RequesterCloudUserID is None. This can occur, for example, if a desktop user has not authenticated against the cloud, or a cloud service not requiring authentication is being used.
  • $RequesterCloudUserID is always the cloud user ID for the requesting user in the cloud in which the evaluation is being done.

Basic Examples  (2)

Give the identify of the authenticated user requesting the evaluation:

Wolfram Language code: CloudEvaluate[$RequesterCloudUserID]

Publish an API that gives the identity of the requester:

Wolfram Language code: api = CloudPublish[APIFunction[{}, $RequesterCloudUserID&]]

Connect as a different user:

Wolfram Language code: CloudConnect["alice@example.com"]

Request the API while connected as a different user:

Wolfram Language code: URLRead[api, "Body"]

Disconnect from the cloud:

Wolfram Language code: CloudDisconnect[]

Request the API while not connected to the cloud:

Wolfram Language code: URLRead[api, "Body"]

Neat Examples  (1)

Log the details of each access to an API, including the identity of the caller:

Wolfram Language code: primes = CloudPublish[APIFunction[{"n" -> Integer}, (PutAppend[{Now, $RequesterCloudUserID, #n}, CloudObject["requests.log"]]; #n -> FactorInteger[#n])&]]
Wolfram Language code: ReadList[CloudObject["requests.log"]]
