I have a text file that I pick up in a Business Service and need to send it to our vendor via JSON.  I assumed (probably wrongly) that I could just create a RESTful Business Operation, plug in the server IP and URL as well as complete some of the other fields on the BO to send the file.  When I do this, I get the following error:

ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>zOnMessage+5^EnsLib.HTTP.GenericOperation.1 *HTTPHeaders,Ens.StreamContainer -- logged as '-' number - @' Set tHeaderKey="" For { Set tHeaderKey=pRequest.HTTPHeaders.Next(tHeaderKey) Quit:""=tHeaderKey Set

Hi Developers,

🎯 Creating REST API with InterSystems IRIS, ObjectScript and Docker

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.

GET /search?param1=value1&param2=value2...

Quick and easy but I'm not sure it's really RESTFul

2. POST body

POST /search
{

Hi!

We are using Rest Service with inheritance of  %CSP.Rest, and we are having the following problem: when we receive 100 request from single IP adress - this creates 100 CSP sessions and takes 100 user licence for each request for few seconds. What can we do do about this? We've  set this parameter:

Parameter UseSession As Integer = 1;

Thank you in advance!

Hello friends,

I am trying to create REST API in Cache. I am getting a response from postman but when I tried to launch the same URL on the browser, I am getting service unavailable error.

This is my URL http://localhost:57772/widgetsdirect/rest/Gunwant

Any help is greatly appreciated.

We've just published an update to the Serenji extension for VS Code. Starting with this version (3.0.7) you can now debug the code that implements your REST services. Here's a taster:

Hi Guys,

Some time ago, InterSystems introduced the concept of %DynamicObjects.
This feature is a powerful tool that makes it very easy to convert any string of JSON text to objects and vice versa.
However, in the work that J2 Interactive is doing for our customers, there are a couple of things that "need some tweaking".

Very often, we create REST services for our customers. Those services have a payload (in JSON format) that contains information that our customer expects in the form of an object that is proprietary to them.
We can easily convert that JSON stream to a %DynamicObject, but, if we try to

Hello!

My goal is to serve files using REST classes only (no filesystem should be used), and I am a halfway far from it.

What I am succeeded in, is serving character files (html/css/javascript/etc) using the next approach:

Object Synchronization is a feature that has been around for a while, since Caché days, but I wanted to explore a bit more how it works. I've always thought that database automatic synchronization is complex by nature but, for some particular scenarios shouldn't be so hard. So I considered a very simple use case (OK, perhaps the typical one, I'm not discovering anything... but if it's common and it works, it's good ). You can download from GitHub and compile it into your system, generate sample data and play a bit with it. It's done for InterSystems IRIS but it also should work in last

IRIS provides us with anti login CSRF attack mitigation, however this is not the same as a CSRF attack, as login attacks only occur on the login form. There are currently no built-in tools to mitigate CSRF attacks on api calls and other forms, so this is a step in mitigating these attacks.

See the following link from OWASP for the definition of a CSRF attack:

https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)

The method shown in this article for mitigating these attacks is currently not proactive, but a minimum that needs to be combined with other attack vector prevention methods,

Hello community,

I am trying to parse the below HttpResponse in Cache. Cannot get the Iterator to work. Is there a single loop which can parse both or single messages and grab the error?

]
}
 

{
error: {
txt1:[
'error msg1',

'error msg2'

Hi Dev Community,

My team is currently working on a project where we need to post pdf documents to a 3rd party REST API.

The API specifies a field in the JSON request message to contain the 'physical content' of the file as an array of bytes, example of the JSON request as follows - data truncated for readability purposes:

{
    "CaptureSource":2,
    "RecipientID":"ID34",
    "Document": {
        "Guid":"5D847A4E9CC1485382DC4A5F5DC80D6C",

I'm not sure how to actually interact with the result set I get from doing something like this.  I want to return something like:

[{"field1":1, "field2":2}, {"field1":2, "field2":10}]

I'm finding it very difficult to get it in this format, since %Print appends a newline onto the end of the {} object it prints.

Here's the closest I've gotten:

set query = "select JSON_OBJECT('field1': field1, 'field2":field2) from MyTable where x=? and y=?"

    set tStatement = ##class(%SQL.Statement).%New()

Hi All,

I have a REST dispatcher class in which I enabled the Parameter HandleCorsRequest = 1;

I can able to access the API using Postman, but not with my web application. It throws the below error.

Access to XMLHttpRequest at 'https://ec2-10-200-XXX-X.com/REST/MRM/get/Message?MessageCode=ERR0006&L…' from origin 'https://ec2-80-106-XX-XXX..com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Is this something need to be modified in the apache config file ?

Hi Guys, 

I have a DB server (ser-app-db) where IRIS is installed as server.

I have a Web server (ser-app-w) where IRIS is installed as web server and configured as CSP gateway.

I followed the configuration guide 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:

http://ser-app-db/REST/CRM/Get?ReqID=123(GET): work and show the request

http://ser-app-w/REST/CRM/Get?ReqID=123(GET): return a 404.

I am using Apache server in Linux box.

I am not sure what I am missing in the config.

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.

Hi dev community,

I am currently working on a project to send documents to a RESTful based API that supports bearer 
Token Authorization.

When we try to fire a JSON request from our EnsLib.Rest.Operation towards the 3rd party API with a 
valid Token we keep receiving Authorization Error codes HTTP 401 back.

If we use the same request and same Token from a test utility such as Postman the request is 
successful and we are able to move past the authorization stage.

We are inputting the Token in the header of the HTTP request as specified by the 3rd party API 
specification.

Hi there,

    I'm trying to develop a  program calling Cache REST service twice with Cors. The first is fetching some information of a patient with GET request, the second is using obtained information to call another REST service(implemented in the same class though) with POST to  perform other tasks.

Is there a quick way to see if an SSL/TLS configuration name is valid, short of switching over to %SYS and checking Security.SSLConfigs:Exists?
