Consume JSON with a CherryPy web application

ajaxJSON.js

//assuming that you're using jQuery

var myObject = { "my_key": "my_value" };

$.ajax({
    type: "POST",
    url: "my_route",
    data: JSON.stringify(myObject),
    contentType: 'application/json',
    dataType: 'json',
    error: function() {
        alert("error");
    },
    success: function() {
        alert("success");
    }
});

jsonApp.py

import cherrypy
import simplejson

class Root:
    
    @cherrypy.expose
    @cherrypy.tools.json_out()
    @cherrypy.tools.json_in()
    def my_route(self):
        
        result = {"operation": "request", "result": "success"}
        
        input_json = cherrypy.request.json
        value = input_json["my_key"]
        
        #All responses are serialized to JSON. This the same as
        #return simplejson.dumps(result)
        return result
