Ok, I have changed my code. Here it is:
Service
angular.module('myModule').factory("service", function ($http, $q) {
var requestUri = 'http://localhost:/localfile.txt';
return {
getData : function(){
var deferred = $q.defer();
var response = $http.get(requestUri);
response.success(function (data) {
deferred.resolve(data);
});
response.error(function (data) {
alert('Error');
});
// Return the promise to the controller
return deferred.promise;
}
}
});
Controller:
var promise = service.getData();
$scope.data = promise.then(function (data) {
alert('Success: ' + data);
}, function (reason) {
alert('Failed: ' + reason);
}
);
When I run it I get the alert that says Failed ...
BTW, if I change my service to this:
getData : function(){
var deferred = $q.defer();
deferred.resolve('1234');
return deferred.promise;
}
Then I get Success
