OpenEdge.http.net.pl server SOAP+XML response into a Longcha

Posted by CMI on 27-Feb-2018 15:25

Sorry if this question has already been asked but the search function on the community page does not seem to be working correctly.

Using the OpenEdge.http.net.pl (httpclient), What is the official way I get the response from the server which returns XML, into a LONCHAR?

The ContentType is "application/soap+xml".

Info:

OE 11.7.2 64bit

OS Windows 10 Pro.

BTW:

This does not work for me:

IF TYPE-OF(oResponse:Entity, WidgetHandle) then
DO:
DEFINE VARIABLE hXmlDoc AS HANDLE NO-UNDO.

hXmlDoc = cast(oResponse:Entity, WidgetHandle):Value.
hXmlDoc:save('longchar ', SOAPResponseXML).
END.

Why not do it like this? Should be pretty easy to trranslate to OE...

using System.IO;

using System.Net;

String URI = "somesite.com/somepage.html";

WebClient webClient = new WebClient();

Stream stream = webClient.OpenRead(URI);

String request = reader.ReadToEnd();

def var URI as char no-undo.

def var oWebclient as class System.Net.WebClient no-undo.

def var oStream as class System.IO.Stream no-undo.

def var lc as longchar no-undo.

oWebClient = New System.Net.WebClient().

oStream = New System.IO.Stream().

oStream = oWebClient.OpenRead(URI).

something like this :-)

Well, not really sure, but I would assume that after:

hXmlDoc = cast(oResponse:Entity, WidgetHandle):Value.


the variable hXmlDoc is already an X-DOCUMENT which contains the entire response from your HTTP call. Works better on Linux as well ;-)

Would this code still work if I ported to Linux?

The Problem is the SOAP+XML is some how not being recognised as being ofType 'WidgetHandle'. This may be because the XML does not have a <?xml version="1.0" ?> header. Who knows??

Somewhere before you call SOAP endpoint, add this line.  This should result in you getting the XML in a LONGCHAR
 
OpenEdge.Net.HTTP.Filter.Writer.EntityWriterRegistry:Registry
           :Put('application/soap+xml':u,    get-class(StringEntityWriter))
 
 
Note that these are static registries (in the sense that they persist for the lifetime of the session, or until you remove the entry.

There is also a BodyWriterREgistrty which is used to convert  the 'real' objects into HTTP bodies. If the XML is not real then you may want to add a similar line to handle the input longchar

OpenEdge.Net.HTTP.Filter.Writer.BodyWriterRegistry:Registry
           :Put('application/soap+xml':u,    get-class(StringBodyWriter))

Hi, Peter.

So I tried both:

OpenEdge.Net.HTTP.Filter.Writer.EntityWriterRegistry:Registry:Put('application/soap+xml':U,  get-class(StringEntityWriter)).
OpenEdge.Net.HTTP.Filter.Writer.BodyWriterRegistry:Registry:Put('application/soap+xml':u,    get-class(StringBodyWriter)).



and the TYPE-OF(oResponse:Entity, OpenEdge.Core.String) = TRUE but the CAST value of the LONGCHAR has a length of '?'.

Still not sure what is going on here?

I’m assuming that the request succeeded? With an acceptable status code?
 
If so, the next step is to check the logs, and then whether anything came back from the server.
 
Add the below to your code and you should have a fair amount of detail written into the log. You will also have request-raw.txt and response-data-received.txt files in your temp-dir; these are the actual (raw) requests and responses sent to the server.
 
log-manager:logfile-name = session:temp-dir + 'logging.log'.
log-manager:logging-level = 5.
log-manager:clear-log().
