Hi, all.
I have CSP application and it needs to get and process data from ajax request with json-content. JSON can be very big.
In this case:
TRY
{
Set RequestObj = ##class(%Object).$fromJSON(%request.Content.Read())
} CATCH(Exception) {
Set Status=Exception.AsStatus()
}
I get just part of getting JSON and validate error in $fromJSON.
If I try to read it all in cycle:
TRY
{
While (%request.Content.AtEnd = 0) {
Set Data=Data_%request.Content.Read()
}
Set RequestObj = ##class(%Object).$fromJSON(Data)
} CATCH(Exception) {
Set Status=Exception.AsStatus()
}
I get <MAXSTRING> error.
Increasing of MaxLocalLengt isn't solution.
Is there some good way parse big JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write.
