Having some trouble parsing the response of my basic AngularJS app that consumes Yelp's API using $httpProvider.interceptors.
This is the structure of my app:
var app = angular.module("restaurantList", []);
The yelpAPI service handles authentication and generates an HTTP request. The received data is output to the Web Console as follows:
app.controller("mainCtrl", ["$scope", "yelpAPI", function ($scope, yelpAPI) {
$scope.restaurants = [];
yelpAPI.get(function (data) {
$scope.restaurant = data;
console.log($scope.restaurant);
});
}]);
The data from the request looks like this:
Object {region: Object, total: 37, businesses: Array[20]}
I aim to parse the array nested in the businesses property. My approach was to utilize $httpProvider.interceptors for this purpose.
The initial configuration of $httpProvider.interceptors:
app.config(function ($httpProvider) {
$httpProvider.interceptors.push(function () {
return {
response: function (response) {
return response;
}
}
});
});
The updated version of $httpProvider.interceptors:
app.config(function($httpProvider) {
$httpProvider.interceptors.push(function() {
return {
response: function(response) {
var old_response = response.businesses,
new_response = [];
for (var i = 0; i < old_response.length; i++) {
var obj = old_response[i],
new_obj = {
restaurant_name: obj.name,
phone_number: obj.display_phone,
yelp_rating: obj.rating,
reservation_url: obj.reservation_url
};
new_response.push(new_obj);
}
return new_response;
}
}
});
});
An error is now showing up -
TypeError: Cannot read property 'businesses' of undefinedEDIT #1
After printing the response using console.log(response), I realized that response.businesses should actually be response.data.businesses. This fixed the error, but now my $http call is returning undefined. Do you have any insights on what could be causing this issue?
EDIT #2
app.factory("yelpAPI", function($http, nounce) {

var consumerSecret = "my_consumer_secret",

signature = oauthSignature.generate(method, url, params, consumerSecret, tokenSecret, {

$http.jsonp(url, {
