Hey @arjun if you could provide more context like the issue you are working on or could raise a draft PR then we can provide you much better insights…
but yeah normally if you want to extract post data then it is typically done by accessing the request object and then parsing the body and specify the method parameter like what the method expects to return after the post request is made
i think you can use rest end points to of controller configiration to do send request from the front end to the back end
look at the controller specific to your page and then follow plus like the earlier suggestion share a pr so that folks can help you out
If your using spring you need the restController class then you can use axios or fetch library to extract the data into the react application you research on that you will not regrate am also studying that notify me if you get most ideal results from your research please
