At the end of our last lesson, we ended with our page displaying a nice (but garish) Angular Material Toolbar, and our Widget data displaying in a list of Material cards.  Our page feels a bit static, and we already know that the large number of Widgets that we will be dealing with will not be especially usable on a static list.  What can we do to help?

A filtering function would be very helpful, so let's add a text input to the top of the page. We will bind this to a variable in the $scope - widgetFilterText so that Angular has access to the value we type in.

We finished our last lesson with our Widgets Direct page receiving a Welcome message as a property of a JSON object, which was unpacked and displayed on the page. However, we are on Lesson 3, and we still haven't had any talk of displaying widgets yet.  

Let's change that.  Widgets Direct are a leader in widget and widget accessories, so we clearly have numerous items to display.   To transfer this, we will need to declare and return our first array.  Let's go back to our REST.Dispatch class, and add this data to our Service.

We are using an F5 load balancer to route public traffic to our IS server. My goal is to block public access to the Management Portal, and only allow what we want to expose, such as REST/SOAP services. At the F5, they can block URL wildcards or specific ports, so those are our options.

Since the URLs for the web services are in the same path ([host]/csp/healthshare/[namespace]/*), I can't see any URL wildcards happening. That leads me to ports; is there a way to put services on a specific port for all services, and everything else stay on a standard web port?

Maybe someone has a logger for  incoming CSP requests and willing to share? Debugging  high traffic HTTPS application and wireshark just doesn't cut it sometimes. So I thought I'd ask here.  I'm especially interested in getting raw stream of incoming request.

Is there a way to generate or create a WADL or some form of service definition for a class containing REST services or on a specific URL?

Let's say I need to process these urls in one REST method:

http://host:port/REST/arg1/arg2/arg3
http://host:port/REST/arg1/arg2/
http://host:port/REST/arg1/arg2
http://host:port/REST/arg
http://host:port/REST/

Currently I need to define URL Map like this (assuming /REST web app):

XData UrlMap
{
<Routes>
   <Route Url="/:arg1" Method="GET" Call="GET"/>
   <Route Url="/:arg1/:arg2" Method="GET" Call="GET"/>
   <Route Url="/:arg1/:arg2/" Method="GET" Call="GET"/>
   <Route Url="/:arg1/:arg2/:arg3" Method="GET" Call="GET"/>
</Routes>
} 

Is there a way to get all these URLs in one route:

This earlier article already announced the new iKnow REST APIs that are included in the 2017.1 release, but since then we've added extensive documentation for those APIs through the OpenAPI Specification (aka Swagger), which you'll find in the current 2017.1 release candidate. Without wanting to repeat much detail on how the APIs are organised, this article will show you how you can consult that elaborate documentation easily with Swagger-UI, an open source utility that reads OpenAPI specs and uses it to generate a very helpful GUI on top of your API.

I have a Enslib.REST.operation which I want to use to send a JSON message. In Ensemble I am using the request message to the Business operation as an input for ObjectToJsonStream function so I can send it out (this is the way to go right?). However, I am now running into the fact that one of the attributes (template_name) contains an underscore and that I am not allowed to use the underscore to define the property in my ensemble RequestMessage:

Property template_name As %String;

What's the best way to resolve this?

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.

The call I am trying to product is a simple ping message to the Mandrill APIat https://mandrillapp.com/API/1.0/users/ping.json (for more details see: https://mandrillapp.com/api/docs/users.JSON.html#method=ping).

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

I created the sample rest services in Cache, I also set output in JSON format.

Can anyone explain how to pass JSON in Rest Services using POSTMAN?

Thanks.

I created a simple CRUD operation using Rest Services in Cache.

 Class EX.example Extends %CSP.REST
{

XData UrlMap
{
<Routes>
<Route Url="/insert/:loc/:ssn/:name" Method="GET" Call="hello"/>
<Route Url="/update/:key/:loc/:ssn/:name" Method="GET" Call="iam"/>
<Route Url="/delete/:key" Method="GET" Call="there"/>
<Route Url="/findid/:key" Method="GET" Call="now"/>
</Routes>
}

ClassMethod hello(name As %String, ssn As %String, loc As %String) As %Status
{
s mName=$zcvt(name,"U"),mKey=ssn,mLoc=loc
s ns=$namespace
znspace "USER"
try{
s obj=##class(Sample.Classes).%New()
s obj.

Hi all,

I have the following problem with a WebApi that I've developed in EBS.

I have a GET method that reads the parameters and puts into a message to process.

Class MyApp.BS.ServiceRestBase Extends (%CSP.REST, Ens.BusinessService)

XData UrlMap [ XMLNamespace = "http://www.intersystems.com/urlmap" ]
{
<Routes>
<Route Url="/login" Method="GET" Call="Login"/>
</Routes>
}
/// Login
ClassMethod Login() As %Status
{

// Get the parameters
set login = %request.Get("login")
set password = %request.Get("password")
set app = %request.Get("app")

I'm trying to implement Crud operation in rest services.

I'm confused about this implementation. 

Is it possible to call rest services method in CSP pages?

If not means, can you tell me another way?

I need some examples or reference to implement Crud operations.

Thanks

Hi, I tried the new rest file in User namespace. But I couldn't run it.

Here the Code:

 Class com.Testing Extends %CSP.REST
{

XData UrlMap
{
<Routes>
<Route Url="/insert" Method="POST" Call="one"/>
<Route Url="/print" Method="POST" Call="two"/>
<Route Url="/update" Method="POST" Call="three"/>
</Routes>
}

ClassMethod one()
{
Write "This is 1st Method!!"
Quit
}

ClassMethod two()
{
Write !,"This is 2nd method"
Quit
}

ClassMethod three()
{
Write 

This is the code here:

I got error in form tag declaring

Can anyone help me to resolve this error!!

Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.

I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.

- This can be slow/bad in applications with large data?

- It's better/recommended to use ZenReports even with ZenMojo applications?

I'm new to learn Rest Services in Cache.

I have REST.DocServer class file in local system. When I tried to run this file I have the error as HTTP ERROR 403. 

Can anyone help me to run this sample Rest Services program?

Thanks in Advance.

Hi,

I have Healthshare/Ensemble version 2015.2.1.

I created Business Operation in my ENSDEMO namespace that will connect to an external REST endpoint to send data to this external REST Service.

I also created an http service in Home>Healthshare>Service Registry, under the Service Type: http. I entered the REST endpoint Name, Host, SSL Configuration, and URL.

In my ENSDEMO production, the Business Operation is using EnsLib.HTTP.OutboundAdpater and my custom Rest business operation class. In the Basic Settings, for HTTP Server, I entered #NameofRegistryService.

Hi-

Im curious if there is any specific configuration that has to be done on an IIS web server to serve up RESTful web services.

I have a server that has IIS installed, with the CSP gateway.  a second server that has Cache installed on it.

I have configured a web application using the Cache System Management Portal for the web services that has a dispatch class pointing to my dispatch class.

I have created an application mapping in my CSP Gateway Management Portal on the web server such that url's with /webservices prefix are routed to my cache server.

I'm currently re-engineering an application from CSP pages directly accessing COS Methods, to an Angular/Material front end accessing a REST DAL.  Both the Angular front end and REST services are hosted from the same Caché instance and the same namespace, but the REST services have their own CSP application, with all calls being routed through a Dispatch class.  

I've come across an architecture issue recently, and am trying to assess the options I have.  At present, we encode a call to a class which takes in an OID and returns the Stream to the browser.

Hi all (and specifically Eduard L. ;)

The Ensemble Workflow REST API provided here:

https://github.com/intersystems-ru/EnsembleWorkflow

(and mentioned before in this Community, also as the basis of the Angular UI, also available in the same Git) 

Has some very basic documentation as to how to work with the API (which also seems to be possibly a little out-dated as I think the /login URL is deprecated, for example).

Is there somewhere a more comprehensive documentation of this API?

Hi,

I am working with this Ensemble Business Operation, which extends the EnsLib.Rest.Operation.

http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY…

I built the OpenWeatherMap Rest Operation described in the article above.

I would like to access the weather.id weather.main, and weather.description. However, these objects are in a JSON Array.

How do you access these three objects in Objectscript.

In my,  Test.REST.WeatherOperation class, I added these three lines.

            set pResponse.WeatherId = tProxy.weather.id
            set pResponse.WeatherMain = tProxy.

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.

Thank you for your help yesterday at the Belfry.

When I try to subscribe to the RSS feeds using some news readers they do not accept them.

The W3C validator makes a lot of suggestions about what might be wrong, but my guess is that the feed title is blank.  Could this be fixed please?

We tested REST Services  as described for Caché DocServer example and for requests using http protocol it works without problems. However when we use the https protocol for the same REST Service it is not available. Our infrastructure is as follows: Apache with openssl, which works on the other hand well for CSP with https. If we switch on the web gateway http trace facility we could see the request of CSP pages by https://. but again a request of a REST Service by https:// will not result in a entry in the tracer.

I'm working on a REST service which will include a binary stream as a request property. I'm currently encoding the stream as BASE64 and passing it as a string value, but I was wondering if there is anything in the Caché JSON support that may be a better fit for encoding this data? Thanks Chris

A beginner’s guide to position Ensemble in regards to MicroServices Architecture (MSA). MSA is getting more visibility in the Enterprise Java world therefore it is vital to understand what is behind the buzz. I make a (humble) attempt to write my view and share with you.

Background

First of all I must confess. Early this summer our Czech colleague Daniel Kutac was asking me to collect some information about a health care product developed in Hungary. When I got the feedback from the related company, it turned out, that the product is a modular system, based on MicroServices Architecture (MSA).

This is a beginner’s guide to the design of a “MicroService” implemented in Ensemble. “MicroService” is a popular phrase these days which has a broad interpretation. My interpretation is: “MicroService” is a “NoSQL Service”. A what? The answer is in the article.

We learnt what the difference is between SQL and NoSQL databases. For me the difference is nearly the same between a SOA Web Service and a “MicroService”. I am going to explain it through an example.

Please note, that although this is a beginner’s guide, I assume deep technology knowledge on data modelling, RESTful services and Ensemble.

Beginner’s guide to RESTful Application Program Interface (API) design and documentation. Through the example you will learn some common pattern for RESTful API.

Before you read

You need to know

• How to create RESTful web service in Ensemble
• How to consume RESTful web service in Ensemble
• How to pass service parameters
• How to return service result

What is a Service API?

What is an Application Programming Interface? Is it something materialized? Is it a single programming unit? What is an API for? From my point of view an API is something which is determined by the program code in an indirect way.
