angular.js - angularjs interacting with backend

Question

Using Angular as a front-end page, how to interact with the back-end (the back-end uses the Flask framework)? For example, how does the front end transmit data to the back end, and how does the back end get the data and transmit it to the front end?

Answer 1

json format $http service

Answer 2

Usually inject $http service and interact with the background through get/post

module.controller("YourCtrl", [$scope, $http,
    function(scope, http) {
    // your controller code here:
    }])
