如何在angularjs中从数据库中添加新行？

<div ng-app="myApp" ng-controller="myCtrl">
  <table>
    <tr>
      <th>Name</th>
      <<th>Email</th>
    </tr>
    <tr ng-repeat="user in users">
      <td>{{user.name}}</td>
      <td>{{user.email}}</td>
    </tr>
  </table>
  <input type="text" ng-model="newUser.name" placeholder="Name">
  <input type="text" ng-model="newUser.email" placeholder="Email">
  <button ng-click="addUser()">Add User</button>
</div>

var app = angular.module('myApp', []);

app.controller('myCtrl', function($scope, $http) {
  $scope.users = [];

  $http.get('/api/users').then(function(response) {
    $scope.users = response.data;
  });

  $scope.addUser = function() {
    $http.post('/api/users', $scope.newUser).then(function(response) {
      $scope.users.push(response.data);
      $scope.newUser = {};
    });
  };
});
