How to call a rest service with Basic authentication
Hi,
I'm getting mad trying to get data from an external REST service that uses Basic Authentication from Ensemble. The BO worked fine when I was using a test server without authentification, but as soon as we need to go to production I cannot have it working.
So far, I've created the username/password at the credentials page (Ensemble-Configure-Credentials). I've setup the BO to use this credentials. But nothing happens.
I've tried with the Rest Client (addon for Mozilla), and using the same address, port and user/pwd works just fine.
So, the question is: how can I use the Basic authentication in a BO in Ensemble? Any help woul be highly appreciated :)
SOLVED: It was my fault... it was failing because of the proxy :P
Are you using EnsLib.HTTP.OutboundAdapter?
Yes, I am. This is the class definition:
}
Everything seems fine.
I'd recommend checking with HTTP Debugging proxy what request actually gets sent. Article on that.
tl;dr plan:
Alternatively if you can run the BO locally you can modify the outbound adapter to send the request with Test=1 value and check what's sent.
Have you looked in the documentation?
Hi,
Yes, we have. Actually, that piece of code worked just fine before the authentication was set on place:
set st = ..Adapter.GetURL(tURL, .callResponse)
If $IsObject(callResponse)
{
}
Now, callResponse is not an object anymore :'(
Hi, at this point I would check what the value of 'st' is, as it seems the GetURL call might be failing.
Hi Steve,
Thanks for your help. Finally I got it working and I didn't remember to come here and close the topic. The error was not at Ensemble but at the proxy server.
Thanks anyway.
I have a working operation that uses the EnsLib.HTTP.OutboundAdapter.
The operation settings that I use are:
1. HTTP Server set to appropriate address
2. Credentials set to an entry in the Ensemble/Configure/Credentials where the username and password are set.
3. Connection Settings/SSL Configuration set to a very basic SSL/TLS Configuration. (This is in System Administrator/Security/SSL-TLS Configurations). By very basic what I mean is that it has a name and that is it. No other details or credentials or anything.
My code then looks like this:
{
set objResponse = ##class(test.Message.ResponseId).%New()
set objResponse.SubjectId = objRequest.SubjectId
set ..Adapter.URL = ..IdQueryURL // Property of the operation, setup in the configuration page
set status = ..Adapter.Get(.HttpResponse,"subjectId,subjectNamespace",objRequest.SubjectId,..IdNamespace)
if status {
set objResponse.StatusCode = HttpResponse.StatusCode
if HttpResponse.StatusCode = 200 {
do HttpResponse.Data.Rewind()
set string = HttpResponse.Data.Read()
set objDyn = ##class(%DynamicAbstractObject).%FromJSON(string)
set objItr = objDyn.%GetIterator()
while objItr.%GetNext(.key,.value) {
if key = "Id" set objResponse.Id = value quit
}
}
}
quit status
}
