Hi Developers!

Today we launched the second programming contest on InterSystems IRIS, the landing.

The topic is the REST API.

And we introduced a few technology bonuses.

Here I want to provide details on what application eligible, what are the technology bonuses and how to collect all of them.

Here we go!

Hello Everyone,

We are currently in process of implementing REST APIs using IRIS and we are also looking at using Intersystems API Manager.

Our aim is to implement a Microservices Architechture where Services are small in size, bounded by contexts, autonomously developed, and independently deployable.

We are following a spec first approach where we are first defining the API specs into Swagger Hub and using IRIS API Management Service to build the REST classes i.e. the Specification class, Dispatch class and Implementation Class.

JSON Syntax

Hi,

I'm using InterSystem Cache v2015.2.5 and I'm implementing a REST API and returning JSON.

Following the documentation I see examples like this

Set obj = {"destinations": ["London","Madrid","Tokyo"]}
Write obj.%ToJSON()

However, I have a compilation error

ERROR #1054: Invalid expression : '{"destinations":'

Is there something that needs to be enabled on Studio to allow this syntax?

Thank you,

Rui

Hi,

So I am a front end developer working with REST API with Cache database on the BE. The BE guys are currently using Cache through a Windows virtual machine and they claim it is not possible to have a development server to work with. All the work they are doing is directly on the production server and changes are immediate and I think this is a bad idea going forward and we most definitely need a development server that has access to the same code base and different version (through git) to be able to do development. We also do all the testing on this production server with test accounts, but we cannot do automated testing with this setup.

Recently i've been using Restforms2 to create a CRUD API for a project. But it lacks some advanced functionality that we need, so we have created a production with a REST WS which handles those advanced methods. That works great but there's a drawback, it does not have authentication.

I would want to use the same authentication method as Restforms2 which is a basic auth using IRIS users and passwords.

Hi All,

Actually, I'm developing few restful API's. I want to create a authentication tokens and display it on my login restful API. If I'm using CSP sessionId, how can I validate the session Id's in another or continues restful API's. else, is there any other approach to handle this task.

My Primary goal is, I have to integrate 2 different front end applications. One is Zen framework another one is web pages from Python.

If any lead, it would be appreciated.

Thanks,

Arun Kumar Durairaj.

Hi All,

I am trying to get JSON data from a REST api. I am using my web browser to get the data by hitting the URL.

The data is receiving properly, but the JSON contains a few HTML tags.

These tags are not not receiving in the browser while hitting the url. Is there any way to overcome this issue ?

Thanks,

WebSockets v REST?

Most frameworks support either REST or WebSockets, and don't make it easy to switch between the two, and/or support both styles of application at the same time. WebSockets offer many advantages over REST, eg:

- most benchmarks show WebSocket messaging to be significantly faster than over HTTP

Hi all

Does anyone have an easy way of reading the cdata in the xml response returned buy a Webservice?

At the moment I have a XML class and then I use read.Correlate() to read through that XML bit.

However, depending on the message I have different things in the CData and I don't want to create a class for each one of these.

The API returns the cddata as KeyValueOfstringstring.

Hello to all,

I'm trying to post some form data from a form I made in React to the backend of cache fetching a REST-service.
Receiving and processing a JSON-object is no problem but how can I handle Form Data?

The frontend is sending the form as form data and also includes one or more files.

What is the easiest way to process this data in my REST.Broker- class?

Best regards,

Simon

Object Synchronization is a feature that has been around for a while, since Caché days, but I wanted to explore a bit more how it works. I've always thought that database automatic synchronization is complex by nature but, for some particular scenarios shouldn't be so hard. So I considered a very simple use case (OK, perhaps the typical one, I'm not discovering anything... but if it's common and it works, it's good wink ).

Hi

I have been experimenting with the creation of a set of REST services for an app. The basic GET operation is set to create a %ZEN.proxyObject instance, and then set an instance of a Persistant class as a property, which gives me all of the values I want to return. However, it also gives me some values that I don't want to return over REST (because they are both private, and large registered objects which will bog down performance)

I need to redirect user to a url, which is 5000+ characters long.
To do that I set:

set %response.Redirect = url

However, in the browser I receive this header:

LOCATION: <First 3972 characters of the 'url' variable>

In WriteHTTPHeader method of %CSP.Response, where the LOCATION header is
written:

Write "Location: ", <Redirect>,!

After I added a buffer flush, after the above-mentioned line:
