GeoEvent Java SDK - Develop custom input (POST)

Question

Hello everyone!

My goal is to develop my own input connector for GeoEvent in Java.
Basically, it is enough to completely repeat the input 'Poll an External Website for JSON', but with some improvement of the 'Post Body' option when using the Post method.

As part of my task, I need to make a Post request and each time specify the ID of a new object in the body. For example, I would like the json to be read from the .txt file and the object ID to be included in the body parameter. As a result, a Post request is made for the object id=22, then the process is repeated again and I request data for the object id=23 and so on.

The goal: to make the input dynamic. So that the object id automatically changes in it.

Can anyone please tell me if this is possible? Where to start? Or is it already possible to use some kind of transport in the sample for development?

This needs to be done within 3-4 weeks. But I am a beginner in Java (I have good experience with javaScript, python).

Thanks a lot!

@EricIronside  Hello!
Thank you so much for your help. This material has been incredibly useful in our research on how connectors work in GeoEvent. We were able to dive deep into how transports and connectors operate.
Unfortunately, the task was limited by both time and our technical knowledge of Java. As a result, we didn’t start developing our own code, though it certainly sounds like a very interesting challenge!

However, while working on other projects, we encountered a similar issue and discovered that similar problems can be solved by creating a custom Python script for GeoEvent Server (ArcGIS for Python API). The articles on the community about how to update input in GeoEvent using Python scripts were very helpful and easy to understand.💛

So, I hope that when the time comes to return to this task, we will be using Python.

Once again, thank you so much for your help! It’s incredibly valuable!🔥

P.S. So, I’d like to mark this comment as the solution. If needed, don't hesitate to use Python!😁
