#API

Good afternoon - I am in the process of writing a AngularJS front-end for some CoS functions that my integration team uses for auditing, analyzing and various other purposes. I have re-tooled the functions to return JSON results that AngularJS can then interpret and display. Many kudos to the AngularJS series on this site for giving me a jump start.

One of these functions uses %SQL.Statement to prepare a class query on %Dictionary.CompiledClassQuery, Summary.This works perfectly if I give the web app making the call %All privileges but obviously I don't want to do that.

Hello Cache Developers:  I was curious if anyone has ever created a TWAIN interface to their Cache Application?  I am new to TWAIN and hence the reason for this question. From what I understand, TWAIN is software used by various digital imaging software and TWAIN provides an API for applications to call to be able to import images into their application.  I work with a healthcare application and was wondering what types of things are required for a Cache Web Application to call the TWAIN API to be able to load images into a Cache table.

Hi I'm using ensemble/cache 2016 is a NTML auth possible. Any code examples?

Currently I've got

set hr3 = ##class(%Net.HttpRequest).%New()
set hr3.Username = "xxxxxx/xxxxxxxxx" 
set hr3.Password = "xxxxxxx"
do hr3.Get("http://xxxxxxxxx/CaseNoteTracking/api/CaseNoteTrackingAPI/Get")

From the looks of things I need a http 1.1 request?

Hi,

Need your help on executing  ##Class(Backup.General).ExternalFreeze() and ##Class(Backup.General).ExternalThaw()   operations in

Atelier REST API setup. Please provide us example code if any.

I am working on my first REST operation concept and had a question about the Property Parameters. If I put a value in CAPTION, does that mean that when I use it in my call that it will come out in the URL?

For example...

Property enumerationType As %String(CAPTION = "enumeration_type");

Then in my operation...

Set tURL=..Adapter.URL_"?q="_pRequest.enumerationType

Hi,

We are trying to write an external backup application to backup Cache Database. After going through the Cache DB documentation, we have found that in Backup.General class there are methods for creating snapshot (Freeze/Thaw) which is required during backup. Are there REST APIs for the same?

Also we have the option of selecting individual DB instances in the management portal.  What are the methods/APIs of getting the DB list, so that user can select individual DB instances in an external backup application ? Do we have the methods/APIs to freeze/thaw the individual DB instances ?

Thanks!

Hi dev community,

I am currently  working on an interface that needs to communicate to a SOAP/ITK endpoint.

I am using the EnsLib.ITK.AdapterKit.Operation.SOAPOperation to interface with an ITK 
service, but it is proving to be more complex than originally expected to set up the web client 
against that particular end-point since I haven't been provided with a WSDL from ITK service side as 
the vendor state they are following the ITK standard and no WSDLs are needed.

I have set up an EnsLib.ITK.AdapterKit.Operation.SOAPOperation within Health Share production and 
we are currently

Hi all.

I want to insert my dataframe into InterSystems IRIS. So, I tried to do this:

df = spark.read.load("/home/imported-openssh-key/zeppelin-0.8.0-bin-all/bin/resultData3/DF.json", format="json")
df.write.format("com.intersystems.spark").\
option("url", "IRIS://localhost:51773/DEDUPL").\
option("user", "********").option("password", "********").\
option("dbtable", "try.test1").save()

And got this error:

Py4JJavaError: An error occurred while calling o80.save.

Hello Experts,

I am working on SOAP WSDL, where I am getting below error, I could not figure out where the error is hitting in code. Error says,

"ERROR #6248: SOAP response is a SOAP fault: faultcode=Client faultstring=Badly formed SOAP Message faultactor= detail= <error xmlns="http://www.intersystems.com/trak/ws"> <text>ERROR #5002: Cache error: &lt;METHOD DOES NOT EXIST&gt;zXMLNew+1^Custom.ENXX.Integration.WebService.Schema.DemogData.1 *%New,Custom.ENXX.Integration.WebService.Schema.DemogData</text> </error>"

I don't have any method as such described in the error -

Hello Experts,

I have a silly question of using InsertParam method and usage. I understand it is name value pair. I am using GET method to send a url and to get the details from server. URL has multiparameter

URL -  api/Identifier/Image/?Verify.EDD={EDD}&Verify.Ethnicity={ETHNICITY}

I have used the URL in a method and called that method directly in the business operation. I am using Insertparam method -

do httpRequest.InsertParam("EDD",..Data.Verify.EDD)
do httpRequest.InsertParam("ETHNICITY",..Data.Verify.Ethnicity)

where httpRequest is an object of %Net.HttpRequest class

Question is how will

SQL gateway.

It is not "compiling" correct the properties(get; set;)  in the class, and generating 2 methods of :

GetuProperty and SetuProperty.

so it's not equivalent to standard  methods interface handling.

SQL gateway.

There is a basic problem with sql gateway,

while building the proxy methods, with:

d ##class(%Net.Remote.Gateway).%ExpressImport(class, port, host, 0, classObj)
it causes error messages as something in the class is not correct,

while this class passed OK all Visual Studio of C#

and same class working OK under the %Activate Assembly link

I think there is also problem  with overload methods (same methods names).

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

Hi everyone,

are you curious which topics we are going to cover at this year’s Global Summit? You have come to the right place! I will provide you with a sneak peek of what you can expect from the areas I am responsible for.

Hi Community!

Please welcome a new video on InterSystems Developers YouTube:

I have an Enslib REST web service using an http host. How can it be converted to use https?

Hi all. Today we are going to use k-means algorithm on the Iris Dataset.

Note: I have done the following on Ubuntu 18.04, Apache Zeppelin 0.8.0, python 3.6.5.

Introduction

K-Means is one of the simplest unsupervised learning algorithms that solves the clustering problem.It groups all the objects in such a way that objects in the same group (group is a cluster) are more similar (in some sense) to each other than to those in other groups.For example, assume you have an image with a red ball on the green grass.K-Means will split all pixels into two clusters.

Hi all. When I try to do this in Apache Zeppelin:

Hi Community,

Is there any way to integrate or access the data from cloud Integration tool called SnapLogic.

Does InterSystems support any integration? Or can you suggest any sandbox available for FHIR to download and access the data.

Thanks

Hello,

In all web services, i need to my get login and token. So with Postman, i tried to call a HTTP request where I put the login/token in the header :

I tried to get data from Http request header. The REST APi use %CSP.REST. I tried something like that : 

But it didn't work..

Someone can give me some example or other method ?

Hi guys,

I am using the %Net.HttpRequest method to get data from a server.

The server will continuously send data. Is there any way that i can able to read the HttpResponse data line by line so that if at a particular line i may terminate the request.

Please advice.

Thanks,

Arya

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?… 
How do the above code works and can i be able to run this?

Thanks in advance.

Hi!

It is often necessary to run some external command such as a python program or a shell script from inside Caché/Ensemble. There are three ways of doing this:

• $ZF(-1) - Runs the command and waits for it to finish.  
• $ZF(-2) - Runs the command and don't wait for it to finish.
• Using CPIPE device - Runs the command and opens a device for you to read its output or (exclusive or here!) write to its input.

$ZF(-1) is normally more interesting because it allows you to recover the return code of the program you are calling.If that is important to you, that is the way to go.

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!

Hi All,

Does anybody has experience with Angular application and have implemented some solution in order to track and record pageviews?

We are interested in to know how to capture those pageviews information and call a Caché REST Api in order to store those data.

Thanks.

I am trying to write an application that will take some information on the database make a call to the Google API distance matrix and get the information to use with rest of the application without using the ensemble part of the development is this possible and how can I do my communication with the  API from a cache class thanks in  advance

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 :

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.

And i am facing the error as below,
