Angular - $http.post send data as json

Question

I have a javascript variable which is an array of MyObjects. I can display this variable to the view with the following code:

    <tr ng-repeat="user in lala.users">
        <td>{{ user.firstName }}</td>
        <td>{{ user.lastName }}</td>
    </tr>

How can I send this to a server as json using post ?

Answer 1

Assuming it's a person object:

let postMessage = JSON.stringify({
  'person': {
    'firstName': this.user.firstName,
    'lastName': this.user.lastName
  }
});

then you can use the postMessage to send it with the:

let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
this.http.post('URL', postMessage, options)

Answer 2

you need to inject $http to you controller or Server or factory.

      $http.post('/saveusers', users).then(function(data) {
        $scope.message = data;
    });
