Details

  • ServiceRequest gives a symbolic representation of a service request; it does not execute the request.
  • The following entries must be given in the association:
  • "Request"request to be made
    "Parameters"parameters for the request
    "Service"name of the service or service object
  • ServiceRequest[…]["prop"] extracts the value for the property "prop" of the service request.
  • Possible properties include all components and additional elements, as well as:

    "Request"request name
    "Parameters"request parameters
    "Properties"list of all possible properties
    "PropertyAssociation"association giving values of all properties

Create a request for "PubChem" service:

Wolfram Language code: req = ServiceRequest["PubChem", "Requests"]

List requests supported by the "PubChem" service:

Wolfram Language code: ServiceExecute[req]

Open a connection to an external service:

Wolfram Language code: pubchem = ServiceConnect["PubChem"]

Create a request:

Wolfram Language code: req = ServiceRequest[pubchem, "CompoundDescription", {"InChI" -> "InChI=1S/ClO2/c2-1-3"}]

Get properties:

Wolfram Language code: req["Properties"]

Extract properties from the request:

Wolfram Language code: req[{"Service", "Request", "Parameters"}]

Get request data as "PropertyAssociation":

Wolfram Language code: req["PropertyAssociation"]

Execute the request:

Wolfram Language code: ServiceExecute[req]

Submit the request and set result:

Wolfram Language code: ServiceSubmit[req, HandlerFunctions -> <|"ResultReceived" -> ((res = #EvaluationResult)&)|>]
Wolfram Language code: res

Build a request with an association:

Wolfram Language code: req = ServiceRequest[<|"Service" -> "PubChem", "Request" -> "Requests"|>]

Execute the request:

Wolfram Language code: ServiceExecute[req]
