Re: Posting Requests To Microsoft Azure

[Paul Park <parkp@xxxxxxxxxx>]

   Hi Rainer
   Thanks for the pointer about Oauth. I'll do a bit of reading on that
   when I next get some "spare" time!
   Thanks,
   Paul

     Hi Paul,
     last year I realized a connection to a webservice with RPG and Oauth
     1.0 authentification.
     This was hard stuff.
     On [1]http://www.itjungle.com/tfh/tfh031815-story04.html is a story
     about Oauth 2.0 on IBM i.
     For testing a Oauth 2.0 connection you can use the RESTClient for
     Firefox or Postman for Chrome.
     best regards

     Hi
     I have a new requirement to post requests to a REST web service
     hosted on a Microsoft Azure platform.  I've had success in the past
     using Scott's HTTPAPI service program to post XML requests to a SOAP
     service, and I believe that posting to REST should be no problem
     either.
     I have two stumbling blocks that I know of, though, and they are
     shown on a page that explains how to make requests to the new
     service -
     [2]https://msdn.microsoft.com/en-us/library/azure/mt428036.aspx.
     I'll list them here:
     1) "To make a data request to the Data Catalog REST service, you
     need to supply an access token. In a .NET client app, you use the
     Windows Azure Authentication Library (ADAL) to get an access token."
     string authorityUri =
     [3]"https://login.windows.net/common/oauth2/authorize";;
       AuthenticationContext authContext = new
     AuthenticationContext(authorityUri);
       AuthenticationResult token = authContext.AcquireToken(resourceUri,
     clientId, new Uri(redirectUri), PromptBehavior.RefreshSession);
     2) "After you get an access token from Active Directory (AAD), you
     use the token to make a web request to the Data Catalog REST API. To
     create a Data Catalog REST web request, you add an access token to a
     request header."
     I have no idea how to tackle step 1 - get an access token. The
     example is .NET, and I suspect I can't do this.
     Step 2 - add the token to a request header might be possible, as
     I've seen examples that use http_setauth to pass a user id and
     password. Can I use http_setauth to send an access token?
     I've already prepared my boss for disappointment on this, but I need
     to know: is there a way to do step 1 in RPG?
     Thanks for any input.
