#API

Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components.

I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.

What this article is about

  • Generation of an AST for a GraphQL request and its validation
  • Generation of documentation
  • Generation of a response in the JSON format

Hello Everyone,

We are planning to build angular UI and Cache REST as backend. Can we deploy angular in Cache Private web server.

What would be the best way to do it. Did any one configure apache with csp gateway . if so can anyone guide me to a good document or some steps here which might help.

I have looked into this - https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY...

Somehow i am not able to join the dots .

I have a simple app which tries to establish a connection with a Cache database instance via Global API for Java:

import com.intersys.globals.Connection;
import com.intersys.globals.ConnectionContext;

public class Assignment {

    public static void main(String[] args) {
        Connection connection = ConnectionContext.getConnection();
        connection.connect("SAMPLES", "_SYSTEM", "SYS");
    }

}

The expection I am getting:

0 36
0 733 
Set httprequest=##class(%Net.HttpRequest).%New()
	Set httprequest.Server="www.intersystems.com"
	Do httprequest.Get("/")
	Do httprequest.HttpResponse.OutputToDevice()
	Do httprequest.Get("/cache/")
	Do httprequest.HttpResponse.OutputToDevice()

The above is the code which i found in this link http://docs.intersystems.com/latest/csp/documatic/%25CSP.Documatic.cls?P...

REST Data Limit

I'm experimenting with sending large amounts of data in a POST payload to be stored as a stream. However I've noticed that no matter how many characters are in the message, Cache only gets about 32k of them, cutting off the rest. Conversely as expected it can only send about 32k worth of characters in a payload.

Before I get creative, is there a REST message size limit that can be changed? Or is there something else going on here?

Thank you!

UPS - SOAP WebServices Not Working

Hi all,

I have started using the UPS in my application for shipment and cancellation.

I have the WSDL from the UPS.

I have imported the WSDL via Studio->Tools->addins and finish the process to get the Package implemeted in my studio.

Now the SOAP method contains a URL which is for their live system so i manually changed the URL with their Testing URL.

They are also providing the sample shipment numbers which we can use to test the cancellation process.

I am trying that shipment number to void(cancel) the shipment by call the method.

First-class functionwiki

In computer science, a programming language is said to have first-class functions if it treats functions as first-class citizens. This means the language supports passing functions as arguments to other functions, returning them as the values from other functions, and assigning them to variables or storing them in data structures. Some programming language theorists require support for anonymous functions (function literals) as well. In languages with first-class functions, the names of functions do not have any special status; they are treated like ordinary variables with a function type.

This post continues the article “Declarative development in Caché”.

[2, 3, 5, 7, 11, 13, 17].forEach(function(i) {
  console.log(i);
});

How to do something like this in Caché using COS?

Below are some exercises on this topic.

TCP adaptor + SSH Tunnel

Greetings.

We have one vendor who requires us to send data using TCP

through an SSH port forwarding tunnel that is set up in advance.

UNIX scripts maintain this, and the Ensemble interface uses a TCP Adapter.

I was thinking that Ensemble could maintain the SSH tunnel,

which would improve our detecting of issues.

Has anyone done something like this?

I see that the class %Net.SSH.Session has a method ForwardPort,

but it doesn't stand up the tunnel by itself. Instead, it appears
