The TL:DR version is there will be a supported one in the 11.5.1 service pack. There is one (a 'tech preview' version) in 11.5.0.

Rest Client in OE 11.5?

Thread created by chrisrichardson

Is there a REST client in OE now (in 11.5)?

The documentation below talks about the rest adapter for the appserver.

http://documentation.progress.com/output/ua/OpenEdge_latest/index.html#page/pdsoe/introducing-openedge-rest.html#

But I want to connect to external rest services from within OE. Is it possible or do I need to create my own (possibly .net)?

Ah OK Peter, thanks for the info.

Any documentation around so I can have a play? - I see in a few of your other posts it's part of the ESAP - is that still available?

Hi,

The ESAP for 11.5 is closed since 11.5 has been released. I've attached the doc that was provided with the ESAP, which will work with 11.5.0. Note that the API has changed slightly between 11.5.0 and 11.5.1 (primarily via refactoring the various types to use interfaces, which the 11.5.0 code does not).

If you have 11.5.0 then you should be able to start playing with the HTTP library.

Thanks Peter, will check this out.

In the mean time I put this together based on some examples on here and elsewhere. This has got me going for now (I didn't want to go down to socket route!)

using System.*.

def var HttpClient as class System.Net.WebClient.
def var webResponse as longchar no-undo.
fix-codepage (webResponse) = "UTF-8". 

def var appKey as char no-undo initial "MyAppKey".

HttpClient = new  System.Net.WebClient().

HttpClient:Proxy:Credentials = System.Net.CredentialCache:DefaultNetworkCredentials.

HttpClient:Headers:Add("key",'"' + appKey + '"' ).

webResponse = HttpClient:DownloadString("http://api.worldbank.org/countries?format=json"). 

HttpClient:Dispose().
delete object HttpClient.

message string(webResponse) view-as alert-box.

This will work , of course, but only on Windows .

Note that the design of the HTTP library completely hides the fact that you're using sockets. The API used to make requests is completely technology-agnostic (so one could switch out the socket-based engine with something else).
