Ways to retrieve API data utilizing the $http service

My current project involves using the Riot Games API, but this example utilizes the REST Countries API. You can find more information at

The technology stack I am using is MEAN.IO and below you will see a snippet of my code:

test.html

<html ng-app="lolData">
  <head>
    <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
    <link rel="stylesheet" href="https://code.getmdl.io/1.1.3/material.indigo-pink.min.css">
    <script defer src="https://code.getmdl.io/1.1.3/material.min.js"></script>
    <meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>

   <section id="center" ng-controller="summonerStats">
      <form ng-submit="search()">
        <div class="mdl-textfield mdl-js-textfield">
          <input class="mdl-textfield__input" type="text" id="summonerName" placeholder="Summoner Name">
          <label class="mdl-textfield__label" for="sample1"></label>
        </div>
        <input class="mdl-button mdl-js-button mdl-button--raised mdl-button--colored" type="submit" value="Search"/>           

      <p ng-show="show">
        {{ mystats.name }}
      </p>

    </form>
   </section>   
</body> 
</html>

test.js

'use strict';

var lolData = angular.module('lolData', []);
console.log("before controller");

lolData.controller('summonerStats', function($scope, $http) {        
   var url = "https://restcountries.eu/rest/v1/alpha/co";
   console.log("inside controller");
   $scope.show = false;       
   $scope.search = function() {                                                          
    $http.get(url)
    .success(function(response) {
        $scope.mystats = response;
        $scope.show = true;
        console.log("inside success controller");
    });
};                
});

Upon refreshing the page, the code runs until the "before controller" console.log statement. However, the browser fails to enter the lolData.controller block, resulting in an error displayed in the console.

Additionally, HTML seems to have issues accepting embedded JavaScript scopes.

If anyone has insights on what might be causing these issues, please share.

Update 1:

I've included the index.html file on Codepen: Index.html

Similarly, the Header.html file is available on Codepen as well: header.html

Answer №1

It seems like you might be experiencing an issue with $http.success (and $http.error) which has been deemed obsolete since version 1.4.4 of AngularJS. The recommended approach is to use callback functions for handling success and error cases.

var url = "https://restcountries.eu/rest/v1/alpha/co";
$http.get(url).then(
  function successCallback(response) {
    $scope.mystats = response;
    $scope.show = true;
    console.log("inside success controller");
  }, function errorCallback(error) {
     console.log(error);
});

Answer №2

It appears that your response object may not be functioning as expected.

According to Angular's documentation, the response object contains various properties associated with the returned data.

To properly handle the response, you should use:

$scope.mystats = JSON.parse(response.data);
