How can I receive a http request in Java/Python? - swift

Question

I am quite new to HTTP requests, I am currently building an app which sends a question to a server, the server sends a response which the app receives and displays on the screen. This is the Swift code I use:
let url = URL(string: "https://reqres.in/api/users?page=2")!
var request = URLRequest(url: url)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
request.httpBody = encoded
print("started request")
URLSession.shared.dataTask(with: request) { data, response, error in
// handle the result here
}.resume()
I have already done a lot of research, but I just found code for sending an HTTP request from Java/Python, not receiving one. I am running my own PC at home which should work as a server, what code do I need in Python/Java to receive the request from Swift and respond to it?

I think that quickest way would be running spring boot app with #RestController class and #PostMapping method inside that will handle your request.
You'll need to create spring boot project with Spring Web dependency from https://start.spring.io/
Download it and add new file with controller class that will handle your rest requests.
Example controller:
#RestController
public class ExamplaryController {
#PostMapping(value = "api/users")
public ResponseEntity<WhateverTypeYouWantToBeReturned> putDataExample(#RequestParam Integer page) {
//code smth here
return result;
}
}
