During simulation some members of the Systems Engineering Professionals Discord server realized that although it is possible to create an opaque action containing Python code in Cameo, but they are unable to use external libraries (like numpy). We came up with an idea how to solve this problem: create a separate application in Python exposing an HTTP interface and write custom opaque actions in Cameo for communication purposes.
This is a Proof Of Concept of calling an HTTP server written in Python from Cameo during simulation.
The application will open a TCP port on localhost and accepts HTTP requests, and sends responses. In the model (see model/PythonSimulation.mdzip) we have custom opaque actions that are able to:
- Create a JSON structure
- Send the JSON structure to the server
- Receive and process the response received from the server
This is strictly a proof of concept and not intended to be used directly in a real system.
Requirements:
- Python latest
- PIP latest
Execute the following commands:
pip install -r requirements.txtto install all the requirementspython app.pyto start the application
To check whether the application is running, enter http://localhost:5000/ in your browser and see the response.
