Issue encountered while attempting to load external JSON file from server in AngularJS

Currently, I am attempting to load a JSON file from the server. Below is my services.js file:

angular.module('starter.services', [])

/**
 * A simple example service that returns some data.
 */
.factory('Friends', function($http) {

  var friends;
 //here is the code for server access
  $http.get('http://wwww.root5solutions.com/ionictest/get.json').then(function(msg){
      console.log("The console output is: "+msg.data);
      friends=msg.data;
      console.log("Data received from server: "+friends.data);
  });

  return {
    all: function() {
      return friends;
    },
    get: function(friendId) {

      return friends[friendId];
    }
  }
});

Unfortunately, it is not functioning as expected. Below is the error message displayed in the console:

XMLHttpRequest cannot load http://www.root5solutions.com/ionictest/get.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access. 

Answer №1

I have encountered the same issue before, but I believe this solution will help you overcome it.

To fix this problem on a Windows system, you can create a Chrome shortcut on your desktop, then right-click on it and go to properties. In the Shortcut tab, edit the "target" path to be: "C:\Program Files\Google\Chrome\Application\chrome.exe" --args --disable-web-security

NOTE: Remember to close Chrome after making these changes, and then reopen it.


Answer №2

Make sure to add the URL to your whitelist

Give this a try

.config(function($sceDelegateProvider) {

    $sceDelegateProvider.resourceUrlWhitelist([
        // Allow same origin resource loads.
        'self',
        // Allowing loading from another domain we own. Please note the difference between * and **.
        'http://wwww.root5solutions.com/ionictest/**',
    ]);
})

Answer №3

The root of this issue lies in my limited testing approach, as I only tested using a browser. Upon testing on an actual device or emulator, the functionality works flawlessly. Fortunately, no additional coding is required to address this problem.
