How to create a real simple json server?

i'm looking a way to create a simple json server which would only get some data and work with them. Without a deep schemas and etc.

All posted answers in web is to deep, difficult, or using deprecated methods/modules :(

All what i need that is:

Client:

requests.post('http://localhost:80108', json={'data':'test'})

Server:

....
....
....
data = json.loads(rcv_data)
if data['data'] == 'test':
    print('Simple test')

Ty for answers. Flask is that what i was looking for.

Server:

from flask import Flask
from flask import request
import json

app = Flask(__name__)

def post_actions(data):
        return {
            'Action1': func1,
            'Action2': func2,
            'Action3': func3,
            }.get(data['Action'])(data['Data'])

@app.route("/", methods=['GET', 'POST'])
def indx():
    if request.method == 'POST':
        if request.data:
            rcv_data = json.loads(request.data.decode(encoding='utf-8'))
            rsp = post_actions(rcv_data)
            if rsp:
                return rsp
            else:
                return '200'
        else:
            return '404'

if __name__ == "__main__":
    app.run(host='localhost', port='43560')

Client:

import requests

data = {'Action': 'Action2',
        'Data': ['MILK', 'BREAD', 'WATER']}

response = request.post('http://localhost:43560/', json=data)
print(response.text)
>>>'200'

So you basically need to exchange jsons with a server? Have you thought of a simple REST API? You can implement one with Flask or even easier with Flask-Restful + standard json module.

This isn't a simple answer but I'd recommend looking at how to make a django api app. It is a good starting point. Then use tutorialspoint to you get you to where you need to be. A previous answer mentioned flask. Flask is very similar to django but I'd recommend django over flask if you plan on building this out as a larger project.

JSON is not the important part here, serializing and deserializing JSON data is done by the standard library json module.

What you need is a simple server that accepts requests and calls Python code; there are several small frameworks that would fit the bill, Flask is a good option.
