Receiving a uncomplete JSON file

#JSON #Ensemble

Hi Guys,

I'm using the below code but I'm getting an uncomplete JSON file, so it seems that the command S obj=Httprequest.HttpResponse.Data.Read(Httprequest.HttpResponse.Data.Size) is not reading the whole file, so maybe the file is too big so is there a max size or can I change something in my call ?

The uncomplete file that I received so far is about 3.5MB 

  

set Httprequest = ##class(%Net.HttpRequest).%New()
  Set Httprequest.SSLConfiguration="RTLS"                              
   Set Httprequest.Server="vibra-api-prod.azurewebsites.net"                 
  Set Httprequest.Https=1
  Set Httprequest.Timeout=30
  set Httprequest.ContentType="application/json"
  Do Httprequest.SetHeader("Accept","*/*")
  Do Httprequest.SetHeader("Accept-Language","en_US")
  Do Httprequest.SetHeader("Authorization","Bearer "_Token)
  set tSc = Httprequest.Post("/api/jobs")
  S StatusCode=Httprequest.HttpResponse.StatusCode
  S obj=Httprequest.HttpResponse.Data.Read(Httprequest.HttpResponse.Data.Size)

 

Thanks

Back of the napkin here, but I'm guessing that Eduard's dynamic object implementation wasn't available in 2014. 3.5mb seems suspicious as a string size limit so I would suggest trying to read the data into a stream explicitly. ex. from the latest IRIS documentation which I believe may still be pertinent to your use case.

Accessing the HTTP Response

set request=##class(%Net.HttpRequest).%New()
 set request.Server="tools.ietf.org"
 set request.Https=1
 set request.SSLConfiguration="TEST"
 set status=request.Get("/html/rfc7158")
 if $$$ISERR(status) {
         do $system.OBJ.DisplayError()
 } else {
         set response=request.HttpResponse
 }
 
 Set file=##class(%FileCharacterStream).%New()
 set file.Filename="c:/temp/rfc7158.html"
 set status=file.CopyFrom(response.Data)
 if $$$ISERR(status) {
         do $system.OBJ.DisplayError()
 }
 do file.%Close()
