The Progress docs spill plenty of ink on SOAP, but I'm having trouble finding the example for a simple HTTP GET/POST with Progress ABL.
How do I GET and POST strings to/from a URL?
Can the URL be https://?
Can Progress provide HTTP Basic or HTTP Digest authentication?
For future onlookers at this question:
Openedge now (since 11.5.1 I believe) has built in support for calling REST based webservices. These are enclosed in a provided .pl archive that is not in your PROPATH by default so that needs to be handled first (or the archive can be moved to a "better location").
The propath can be set in a number of ways, init files, registry, programatically etc. This is how it can be done in ABL (if done this way it must be repeated for each new session).
PROPATH = PROPATH + ",c:\pathtoprogress\OpenEdge\gui\OpenEdge.Net.pl".
There's also a version in "tty" directory, as well as an archive containing source code in the "src" directory.
Here's a very basic example:
USING OpenEdge.Net.HTTP.IHttpRequest.
USING OpenEdge.Net.HTTP.IHttpResponse.
USING OpenEdge.Net.HTTP.ClientBuilder.
USING OpenEdge.Net.HTTP.RequestBuilder.
DEFINE VARIABLE oRequest AS IHttpRequest NO-UNDO.
DEFINE VARIABLE oResponse AS IHttpResponse NO-UNDO.
oRequest = RequestBuilder:Get('http://stackoverflow.com/'):Request.
oResponse = ClientBuilder:Build():Client:Execute(oRequest).
MESSAGE
oResponse:StatusCode SKIP
oResponse:StatusReason SKIP
VIEW-AS ALERT-BOX.
Documentation for 11.6 can be found here.
