Retrieve items in Angular by sending a POST request

Question

Retrieve items in Angular by sending a POST request

I am currently developing my first application using Angular and have encountered a challenge. I have the address for a POST request with an authentication token, structured like this:

http://example.com/orders?authentication_token=123456

I need to implement a ng-submit or ng-click function that will send this request, retrieve a set of items, and display them on the page. Additionally, I have a JSON body structure for the items:

{
"order": {
    "seller_id":84,
    "price":123,
    "delivery_date":"12-12-2025",
    }
}

What is the most efficient way to achieve this?

Answer №1

In order to achieve your goal, you will need to create an angular service that communicates with the server to fetch data, and an angular controller that interacts with the service to retrieve the data and display it on the user interface.

Let's name the service MyService:

app.service('MyService', function($http) {
    var params = {}; // some parameters
    this.getData = function(successCallback, failureCallback) {
        $http.post("URL", params).then(function(data) {
            successCallback(data);
        }, function(data, status) {
            failureCallback(data, status);
        });
    }
});

The controller will be named MyCntrl:

app.controller('MyCntrl', function($scope, MyService) {

    function successCallback(data) {
        $scope.itemList = data;  
    }

    function failureCallback(data, status) {
        $scope.itemList = {};
    }

    $scope.handleClick = function() {
        MyService.getData(successCallback, failureCallback);
    }
});

I am confident that this approach will help you meet your requirements!

Imagine you have an orderCtrl in your application. Depending on your app's requirements, you can use either ng-click or ng-submit. Invoke the function someFunction() which initiates a $http post request, allowing you to handle both successful and failed responses.

app.controller('orderCtrl', function($scope, $http) {

  $scope.someFunction = function(){
  var data = {}; // Prepare your data here. 
  $http({
    method : "POST",
    url : "specify your url here",
    data : data
  }).then(function mySucces(response) {
      var response = response.data;
       // Handle your success here
    }, function myError(response) {
      // Handle the failure here
  });

 });
});

Note :

If you are using a form and you want to trigger this function after the user has filled in all the information, then use ng-submit. If it is independent, then use ng-click.

I want to emphasize again, it all depends on what you are trying to achieve.
