How to access external resource (JSON DATA) via $resource in AngularJS

I'm trying to retrieve weather data from openweathermap.org (JSON) ,

this is my service code:

weatherApp.service('forecastService', [ '$resource', '$sce', function 
 ($resource, $sce) {

    this.getWeather = function (city, numDays){

        var key = 'b3cc85931eae059522f3a9b8c5260f6e';

        var link = function() {
           return $sce.trustAsResourceUrl("http://api.openweathermap.org/data/2.5/forecast/");
        };

        var weatherAPI = $resource(link(), { callback: "JSON_CALLBACK" }, { get: { method: "JSONP" }});

        var weatherResult = weatherAPI.get({ q: city, cnt: numDays, appid: key });

        return weatherResult;
    };

}]);

this is my controller code:

weatherApp.controller('forecastController', ['$scope', '$log', 'forecastService', function($scope, $log, forecastService) {

    $log.info(forecastService.getWeather('Davao City', '5'));

}]);

Kept on getting this error, please help T_T

I know it is too late, but I just had the same question as you did and solved.

I think the issue comes from using trustAsResourceUrl, it passes the url as undefined when angular tries to split it, it gives an error.

I just added the openweathermap domain to the whitelist and then create the resource without trustAsResourceUrl:

weatherApp.config(function($sceDelegateProvider){
    $sceDelegateProvider.resourceUrlWhitelist([
   // Allow same origin resource loads.
   'self',
   // Allow loading from openweathermap
   'http://api.openweathermap.org/**']);
});

And then create the resource:

$scope.weatherAPI = $resource("http://api.openweathermap.org/data/2.5/forecast", {get: {method: "JSONP"}});

Notice that I removed the { callback: "JSON_CALLBACK" }, it was causing another error.

Regards.
