Hi,
I am successfully using the WebClient class in my code to send data to a server using the UploadValues method. When this works I receive a JSON object back containing, among other things, a status code of 1. If I send some invalid data to the server I should still receive a JSON object back but this time the status code should be 0 to indicate there was a problem. When the server issues a status of 0 it also raises a HTTP 4xx error which the WebClient throws as a System.Net.WebException. Is there a way to ignore the WebException because when my CATCH block catches it I dont actually receive my JSON object.
I am using 10.2B08.
Thanks.
My code looks like the following:
ASSIGN
lvWebClient = NEW System.Net.WebClient().
ASSIGN
lvByteResult = lvWebClient:UploadValues("serveraddress", lvParameters).
ASSIGN
lvEncoder = NEW System.Text.ASCIIEncoding().
ASSIGN
lvJsonString = lvEncoder:GetString(lvByteResult).
ASSIGN
lvReturnValue = TRUE.
CATCH e AS System.Net.WebException:
ASSIGN
THIS-OBJECT:ErrorMessage = e:getMessage(1).
END CATCH.
Thanks Peter. I have sorted this now and for anyone who may need it in the future here is what I did:
CATCH we AS System.Net.WebException:
DEFINE VARIABLE lvReader AS CLASS System.IO.StreamReader NO-UNDO.
ASSIGN
lvReader = NEW System.IO.StreamReader(we:Response:GetResponseStream()).
ASSIGN
THIS-OBJECT:ErrorMessage = we:getMessage(1).
lopResponse:ParseXmlResponse(INPUT lvReader:ReadToEnd()).
END CATCH.
