Rest Services In MDriven

REST Services are services executed by connecting to a URL that defines operation and parameters and returns an answer – not seldom as JSON objects.

You must set the tagged value RestAllowed on the ViewModels you want to allow Rest access to.

Calling Existing REST Services

MDriven supports a couple of EAL operators to manage REST services. All operators reside on the selfVM variable which is available only in the ViewModel context.

Note! optionalnestingwithheaders is the name of the blue ViewModel class in the example below (as an OCL String).

The action GetExporttest retrieves data by converting another ViewModel to XML - it stores it in the variable vText.

The next action invokes RestPost to send that data to a URL address; it also says it should look at the nesting named 'Xml'. In this nesting, we have the STRINGCONTENT (see also OCLOperators RestPost) which gets its content from the vText variable. We also add the header Authorization with a bearer token to get access from the receiving service.
