#REST API

19

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.

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!

I am trying to use the automated unittest class for a %CSP.Rest service.

So my Unittest code set's %request and %response from %CSP.Req/resp respectively

I build a tProxy with the fields I need for the post and set it %ToJson... I have tried seting %request.Content = tProxy (and not)

I call the method for the post url directly...

When that method calls %fromJson to set an object with the info. I passed...

- when I don't set %request.content.. I get a error '5035 - premature end of data code 12'

Retrieving REST Data

I'm sending data via ajax to my REST service, and while retrieving any information sent in the url parameter is easy when they're defined in the route, I can't get anything if I store information in the data parameter. For example:

$.ajax({
               url: "ServerURL",
               data: { "some": "json" } //How do I get this information?

...

I've looked at many common solutions such as here:

Hi.. I have an issue where we are using OAuth2.0 with the ZAUTHENTICATE routine. Once our token is validated we are using a users lan id (passed on the ID token) to find a software defined username in a Cache Global.

That is all working fine in ZAUTHENTICATE.. I am setting the software defined username in the Properties("Comment") array and wanting to reference it in the Rest Service Dispatch class.

I have an Ensemble installation and just build my first RestService (using %CSP.Rest that forwards them to my Business Service). This works nice and fine when I use postman to make REST calls over http (port 57772). However when I attempt to make a request using https over port 443 I receive the following error:

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.

Hi everyone! My company has a Zen ERP application with CSP delegated authentication. Now, we're developing a separated BI application, using Angular, which consumes DeepSee REST API services. Both applications access the same Caché database.

How to implement single sign-on strategy in order to allow an already authenticated ERP user to access DeepSee REST services? Has anyone already implemented something like that?

Thanks in advanced.

Posting to a REST service

Hello,

I come from a programming background, but haven't touched ObjectScript before my current job, so please forgive my ignorance.

Within an Ensemble system, I need to post some information to a RESTful web service. I'm just trying to figure out how to create a method which takes a simple message and posts this off to a RESTful web service?

Thanks in advance for any help.
