Hi dev community,

I am currently working on a project to send documents to a RESTful based API that supports bearer 
Token Authorization.

When we try to fire a JSON request from our EnsLib.Rest.Operation towards the 3rd party API with a 
valid Token we keep receiving Authorization Error codes HTTP 401 back.

If we use the same request and same Token from a test utility such as Postman the request is 
successful and we are able to move past the authorization stage.

Authentication with REST

We are building a bunch of rest based services using Ens 2016.2 to serve our browser based application (Angular 4).

Two questions:

1. The initial authentication seems only work if credentials are placed in the url parameters.  Trying to use the Authorization header instead, the client code immediately complains about Access-Control-Allow-Origin. How can I resolve this?

 

2. After initial authentication, what is the proper way to send subsequent rest calls without having to include credential every time?

Posting to a REST service

Hello,

 

I come from a programming background, but haven't touched ObjectScript before my current job, so please forgive my ignorance.

 

Within an Ensemble system, I need to post some information to a RESTful web service. I'm just trying to figure out how to create a method which takes a simple message and posts this off to a RESTful web service?

 

Thanks in advance for any help.

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.

Hello,

 

I have a DB server (ser-app-db) where cache is installed as server.

I have a Web server (ser-app-w) where cache is installed as web server and configured as CSP gateway.

I followed the configuration guide (https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY...) and ser-app-w perfectly display the CSP and CLS pages.

 

But that's not working for my REST service, for exemple with the REST sample:

Is there any good documentation/tutorials on creating gateways in both directions between FHIR and Hl7v2 (for Health Connect)?

the scenarios I'm most interested in

1. Client application sends a FHIR demographic query to Health Connect - and the interface has to convert this to Hl7v2 QBP^Q11 message to the PAS.

2. Health connect sends a PDF document (from a file or HL7v2 interface) to an EPR over FHIR.

Thanks

Stephen

REST and IO redirection

Problem: I have a REST broker, and if I hit a code block, which does IO redirection, the REST reply becomes broken in one of the following ways:

  • Binary output
  • No output
  • First 4096 characters of the reply are missing

Consider the following REST broker:

I am relatively new to ensemble, but I am trying to build a REST operation using the enslib.Rest.Operation but I can't seem to get it to work at all. I am completely at loss here because the errors I am receiving are very unclear. I have tried a few different variants using PostURL and SendFormDataArray but I got errors on all variants. Suggestions are welcome.

Hi Dev Community,

My team is currently working on a project where we need to post pdf documents to a 3rd party REST API.

The API specifies a field in the JSON request message to contain the 'physical content' of the file as an array of bytes, example of the JSON request as follows - data truncated for readability purposes:

How do you search with REST

The question is pretty much in title. I'm developing a REST API, it has a search endpoint with 10 optional parameters. How do I pass them and stay RESTFul?

To ease the question a bit let's agree that:

  • all parameters are AND parameters, user can't make combos, ORs, etc. User can only provide values
  • all values are integers so I don't have to think about URL limits
  • all values are atomic
  • all conditions are about equivalency

Some options I know of:

1. URL parameters.

The REST webservice works perfectly when run on SOAP UI. This end point server is an https site that uses basic authentication (uname and pwd).  But when I run the request through an Enslib.Rest.Operation using a configured SSL and stored credentials, I get an "unauthorized" error, unless I explicitly hard code the password in the operation class. HS Version is 2014.1 .

I have 2 questions. Pardon me, they are both related!!

AWS API calls

This question is about calling AWS REST APIs. Based on:

http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html

AWS requires REST clients to call their APIs using Signature Version 4 which in case you don't know what I am talking about is a pain in the neck.  Here comes the question:

Has anybody, by any chance implemented the v4 signing alg. in COS? If yes, would she or he have the kind heart to share?

Thanks,

Chris

Hi,

I was looking at the ENSDEMO namespace in our Ensemble server. In the class Demo.REST.DirectoryOperation, there is a line that uses the macro $$$URLENCODE. I would like to know exactly what does this macro $$$URLENCODE() do. Specifically what value does it. Unfortunately, I can't find anything about this macro in the Ensemble Documentation.
