#REST API

17

Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services. Web services that conform to the REST architectural style, called RESTful Web services (RWS), provide interoperability between computer systems on the Internet. RESTful Web services allow the requesting systems to access and manipulate textual representations of Web resources by using a uniform and predefined set of stateless operations. Other kinds of Web services, such as SOAP Web services, expose their own arbitrary sets of operations.

Hi,
Trying to work with REST protocol, using IIS 8, both client and server are Cache servers,
I have the following problem-
When I send a PUT command, I get the following error:
<HTML><HEAD><TITLE>Length Required</TITLE>
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<BODY><h2>Length Required</h2>
<hr><p>HTTP Error 411. The request must be chunked or have a content length.</p>
</BODY></HTML>

Hi All,

I hope someone can help me with the following, it's about the usage of the class EnsLib.HL7.Service.HTTPService.

Working situation right know.

In IIS we've got a site configured who is dealing with the client certificate, etc and redirect the full request to http://localhost/csp/healthshare/NAMEPSACE/EnsLib.HL7.Service.HTTPServic... and the web gateway redirects the request to Business Service 'EnsLib.HL7.Service.HTTPService.cls'.

Hi all,

When passing on the content of a file in a REST API call, I need to put the original file name in an HTTP header. As it happens, some file names have non-8-bit characters in them ("å", "ö", and the like), and these arrive garbled on the other side. Does anybody know the correct way to encode them (assuming they should be encoded at all)?

$zconvert(filename, "O", "UTF8") does not appear to be it. I'm leaning towards $zconvert(filename, "O", "URL"), but leaning isn't good enough.

Thanks,
Otto

This quick guide shows how to serve HTTPS requests with InterSystems API Management. Advantage here is that you have your certs on one separated server and you don't need to configure each backend web-server separately.

Here's how:

1. Buy the domain name.

2. Adjust DNS records from your domain to the IAM IP address.

3. Generate HTTPS certificate and private key. I use Let's Encrypt - it's free.

4. Start IAM if you didn't already.

5. Send this request to IAM:

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

or "Bonus Breakage"

In our last lesson, we added a relationship between 2 persistent classes. We are clearly going to need to start creating REST Services to expose CRUD operations for each of these classes, but before we do that, we should really finish defining our linkages. We added code to our Widget toJSON to spool off related Accessory data, so we should really do the reciprocal and allow Accessories to return all Widgets that are compatible.

I have tried many methods from super classes of %CSP.REST but I can't find a method I can override that will run after the %response object is created so I can set a header that is common to each implementation method. It's one line of code in each method to set the header but it would like to make it super easy, simple and just have a method that runs on, before, after the implementation method to set this common header (we want to return the API version in each responses HTTP headers.

IIS Routing Question

I have a question about the routing of IIS.

If I have a javascript application that has a single entry point app.html. Is it possible to configure the IIS server such that both the urls

addr:port/entry1

addr:port/entry2

to provide the same app.html and let the javascript code from application decide what component to load next, depending on the path of the URL ?

My IIS server is configured such that when I do a GET url1, ir tries to send entry1.html , respectively entry2.html when I do GET url2.

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?

Hi Developers!

I stuck with one interesting problem.

For example, let's use this template repo. If you build this container A using docker-compose and then run the container it exposes REST-API which is available on:

localhost:52773/person/all

The question is how to make this REST-API accessible from another docker container B running on the same machine? E.g. with IRIS 2019.4 Community from this repo?

The problem is that for the second container localhost it's something which belongs to container B.

I think I need to set up a network between containers somehow. E.g. using docker-compose. But is there any simpler way?

_spec for swagger-ui from spec class

Surely you wanted to use the OpenAPI Specification (OAS) JSON you used for your spec class on the iris-web-swagger-ui iris package. The generated OAS from the ##class(%REST.API).GetWebRESTApplication(...) method is very crude, with no description on the parameters or the expected response structure.

So after creating your REST application from an OAS you should have:

DNA Similarity and Classification was developed as a REST API utilizing InterSystems Vector Search technology to investigate genetic similarities and efficiently classify DNA sequences. This is an application that utilizes artificial intelligence techniques, such as machine learning, enhanced by vector search capabilities, to classify genetic families and identify known similar DNAs from an unknown input DNA.
