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Post-
processor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.
Itisnotpossibletousetheasyncmode,whichcanbesetviatheopen()functionoftheScript-
ableHTTPRequest(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.
