Hello

I'm in the process of creating a TestClass which simulate a HTTP POST call to REST-based web services and while I am having success, I'm struggling on how to parse out the results to a JSON format

Here is down the code part which concerns parsing the HttpResponse.Data variable into JSON :

s httprequest=##class(%Net.HttpRequest).%New() 
s httprequest.Server="http://127.0.0.1"
s httprequest.Port="57772"
s httprequest.Https = 0
s httprequest.ContentType="application/json"
s httprequest.Authorization = "Basic X1N5c3RlbTpTWVM="
d httprequest.EntityBody.Write(json)
s sc = httprequest.

Hi All,

I am new to webservice and UPS. I have tried the sample URL's that UPS have given for testing in PHP codes and it works just perfect for me.

But when i try to hit the same URL's in Ensemble. it gives some errors from UPS.

If anyone of you guys here has any knowledge about UPS integration or the webservice please help me. it will be much appreciated and helpful.

The ensemble code that i am trying with is,

  set AuthToken=##class(%Net.HttpRequest).%New()
  set AuthToken.SSLConfiguration="UPS"
  set AuthToken.Https=1
  set AuthToken.Server="wwwcie.ups.com"
  Set AuthToken.

Catching Bad Guys with iFind and 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:

Hi guys,

is there a way to get the Call-Parameter in an UrlMap to call a method that lies in another class?

Example:

I have a generic class 'RestApi' where I define all my routes for the different Rest-Services I offer - in order to get the same URL for every service.

 <Route Url="/checkUID/:uid/:supplierid/" Method="GET" Call="checkUID"/>

This way the checkUID-Method has to be in the class 'RestApi' where my routes are defined.

Building Durable APIs: New REST Tooling

Hi Guys,
Can you please guide me to get rid of this issue. Please find the image files with this post.

Please let me know, before we are developing an API what are all the setup/Configuration(Apache/web server) need to do in my machine. 

If any lead would be appreciated. 

I don't know, in XMLNamespace parameter which URL need to use.  

.

Thanks,

... but let’s first look at error handling.

How do I set an URL when I post a httpRequest via SendFormArray of my Ensemble Business Operation. Here is my code: 

Class CareHome.RestApiClient Extends EnsLib.REST.Operation
{
Parameter INVOCATION = "Queue";
Method Login(pRequest As CareHome.Request.LoginRequest, Output pResponse As Ens.StringResponse)
{

set tURL = ..Adapter.URL_"login/login"

set httpRequest = ##class(%Net.HttpRequest).%New()
 set httpRequest.ContentType="application/json"
 do ..ObjectToJSONStream(pRequest,.jsonStream,"aeliw")
 set httpRequest.EntityBody = jsonStream
  
 set tSC = ..Adapter.SendFormDat

I have an application in Cache 2013 (No Ensemble) which need to consume a REST web API over internet.

Can somebody please help me by pointing out the documentation or provide me code sample  for consuming the REST API from a routine/class.

I am using Cache 2008 (No Ensemble) .

I have an Ensemble installation and just build my first RestService (using %CSP.Rest that forwards them to my Business Service). This works nice and fine when I use postman to make REST calls over http (port 57772). However when I attempt to make a request using https over port 443 I receive the following error:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html>
    <head>
        <title>404 Not Found</title>
    </head>
    <body>
        <h1>Not Found</h1>
        <p>The requested URL /csp/healthshare/fcoffice/rest/ping was not found on this server.

As many of you, our partners, are more widely using modern UI frameworks to create client front-end, you may have encountered a question, "So how do I secure my data when I just finished developing all new fancy browser based client experience?"

The answer is easy. Use a standard, proven OAuth2 and OpenID!

"OK, but how can I do it? I have never done it before."

No problem, just have a look here, if your client is Angular (not AngularJS) based, there is a demo project available for you to review and get inspired!

Hello, evrybody, I'm writing one project using CSP("OnPreHTTP"), and also REST angular. At the beginning I wrote purely on csp, then I decided to use angular for the flexibility of the client part. Now I can not design logging, I created a table App.

Hi, Community!

Suppose If you develop a client js application which works with Caché server via REST API (CSP Gateway).

What are the options for Authentication and working with Caché session then?

Hi team,

i send an http request to my rest class, i want to extract ID , full name , pass word from this request , can you show me how doing it.

thank's

Angular, JSON, and REST – Oh My!

Hello again and welcome to the next tutorial on this series: Part 4 - Sharing data across router methods.  Here we are going to learn how to share a object containing data that is available for read across every router methods.
You're required to complete at least the Part 1 before entering this one. Still, this is supposed to be a really short tutorial, since there isn't much to be said about data sharing.

I am sending a file in Postman and receiving a status 200OK. but i need to get the response in the body too. I have Implemented the class %CSP.REST to get the %request and %response. There is no default method to invoke and post the content via %Response class. Can any one suggest me the sample code for that.

Hi everyone! My company has a Zen ERP application with CSP delegated authentication. Now, we're developing a separated BI application, using Angular, which consumes DeepSee REST API services. Both applications access the same Caché database.

How to implement single sign-on strategy in order to allow an already authenticated ERP user to access DeepSee REST services? Has anyone already implemented something like that?

Thanks in advanced.

Hello again and welcome to the Part 3 - Using the SQL API!
If you have been wondering about how to use SQL along with Frontier, you came to the right place. That's because since Frontier wraps the common Caché SQL API within it's own, you need to use the API provided from it. But you don't need  to worry about its learning curve, because the Frontier SQL API is really simple.
If you arrived here without checking the Part 1, I'd recommend you doing so, because Part 1 covers the essential for getting started with Frontier routers.

Hi, 

I am a beginner on intersystems technologies ! and i want implements Oauth2 for our projects ( Angular 2 + Caché REST  Backend). 

i read the article that the link  is below : 

https://community.intersystems.com/post/cach%C3%A9-open-authorization-framework-oauth-20-implementation-part-1

But : i need to create  all servers ( Auth and Resource ) on Caché and dont' to use google server.

Also, i need   to be able to consume Oauth from my web services as caché REST application (whitout csp ui) .

An Idea  Please ?

Thank you

Yani

I've mentioned the QEWD project in this group before: it's a Node.js-based platform for web, Native and REST applications which tightly integrates with Cache.  It uses a somewhat different philosophy to the use of Node.js than the norm, and I've now published an article that explains this approach and the unique benefits that arise as a result.

It turns out that, integrated via QEWD, Cache is an ideal bed-fellow for Node.js.  QEWD makes the integration of Cache and Node.js exceptionally fast, simple and intuitive to use, but also extremely powerful.

Hello again! Welcome to the Part 2 - Handling payloads! 

If you're new to this series, I'd recommend you to check out the Part 1 - Core concepts. You'll need a basic understanding about how Frontier works before continuing with the Part 2.

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

REQUIREMENTS:

• Caché 2016.2 or higher.
• Frontier.

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.

Hi

I tried to access one server to another server in Cache Rest Service, I tried 

Parameter HandleCorsRequest = 1;

and

<Route Url="/data/:first/:second" Method="GET" Call="GetData" Cors="true"/>

But not working,

Can anyone tell me the solution??

Thanks in advance!!
