createHTTPRequest()
Function that creates a new ScriptableHTTPRequest object, in order to issue REST/AJAX calls
to external servers.
This feature allows the data mapping process to complement its extraction process with
external data, including data that could be provided by an HTTP process in Workflow, for
instance a process that retrieves certain values from Workflow’s Data Repository. Another
possible use is to have a Postprocessor that writes the results of the extraction process to a file
and immediately uploads that file to a Workflow process.
The returned ScriptableHTTPRequest has a selection of the properties and methods of the
standard JavaScript XMLHTTPRequest object (see https://developer.mozilla.org/en-
US/docs/Web/API/XMLHttpRequest). Supported properties and methods are listed below.
Note
It is not possible to use the async mode, which can be set via the open() function of the
ScriptableHTTPRequest (see https://developer.mozilla.org/en-
US/docs/Web/API/XMLHttpRequest/open) in a data mapping configuration. Async-related
properties and methods of the ScriptableHTTPRequest object - for example .onreadystatechange,
.readyState and .ontimeout - are not supported.
The reason for this is that by the time the response comes back from the server, the DataMapper
script may have finished executing and gone out of scope.
