Hello All,

I am just wondering if there is any inbuilt function or utility available in IRIS to clean up "null" elements from JSON e.g. I want to remove "null" elements from payload below before I do any processing with it.

{

recipients: [ 

{ "name":"Utsavi", "email":"utsavi@gmail.com"},

{ "name":"Utsavi 1", "email":"utsavi1@gmail.com"},

null, null

],

content:[null, {"title":"Test.pdf", "data":"ygwehfbnwfbhew"} ]

}

Thanks & Regards,

Asynchronous REST

In this article I'd like to discuss asynchronous REST and approaches to implementing it.

Why do we need asynchronous REST? Simply put - answering the request takes too much time. While most requests usually can be satisfied immediately, some can't. The reasons are varied:

  • You need to perform time-consuming calculations
  • Performing action actually takes time (for example container creation)
  • etc.

The solution to these problems is asynchronous REST. Asynchronous REST works by separating request and real response. Here's an example, let's consider the following simple async REST broker:

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.

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:

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.

Hello.

The idea of this post is to introduce Frontier: An abstraction layer that allows Rapid REST development.

REQUIREMENTS:

Why?

Have you ever found yourself dealing with repetitive tasks like mounting objects, serializing them and eventually handling multiple errors for multiple cases? Frontier can boost your development by making you focus on what really matters: your application.
 

Frontier is made to stop you from WRITE'ing by instead forcing your methods to return values.
It's designed to make you code clean, and you'll see the why pretty soon.

This is the Part 1, where you'll learn he basics about how to work with Frontier. That means at the end of this part you should be capable of 

creating GET requests without difficulties. Since this also serves as a way to introduce the framework, I'll be calling this part: Core concepts.

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:

Retrieving REST Data

I'm sending data via ajax to my REST service, and while retrieving any information sent in the url parameter is easy when they're defined in the route, I can't get anything if I store information in the data parameter. For example:

$.ajax({
               url: "ServerURL",
               data: { "some": "json" } //How do I get this information?

...

I've looked at many common solutions such as here:

REST POST 405 error

I'm testing out the new %CSP.REST way of creating an api and having a problem with a POST getting a 405 error.

I get data returned when I do a GET, so I don't think it's a configuration issue or a class issue.

I have no problem with %CSP.Page when creating a REST type method. So what am I missing?

Can someone give me some advice?

Thank you.

Hello,

I want to convert a json, which passed on in the a REST call, into a request message. 

I use method %ConvertJSONToObject of the %ZEN.Auxiliary.altJSONProvider class.

Set sc = ##class(%ZEN.Auxiliary.altJSONProvider).%ConvertJSONToObject(%request.Content, "TestRequest", .request)

Is there an alternative for this? I want to avoid to use the %ZEN library.

Best Regards

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.

REST Services Cataloging

I've been building up a REST services API, consisting of a dozen or so classes referenced from a Dispatch class, which has route mappings for the first piece of the URI.  I'd like to have the Dispatch class be able to output all of the available Services, with some documentation.  Is there something like a %Library resource that I could use to pull this information from each of the classes?

Thanks

Chris
