How to make http call in service but get response by the controller? AngularJS
I`ve got a service where I call http,the problem is that I dont understand how to use $scope.photos in the controller.How to config controller and service to do this?
app.service('httpService',function($scope,$http){
function getAll() {
$http.get('/allphotos').then(function success(response) {
$scope.photos = response.data;
}, function error(err) {
console.log('error is:' + err.err)
});
}
});
app.controller('ctrl',function ($scope, httpService) {
}

First of all never use $scope inside Service/Factory/Provider. The scope is related to controllers only, a.e. deals with bind views with controllers.
You have a method getAll() that should return Promise and you will be able to resolve it inside your controller.
Something like:
app.service('httpService',function(,$http){
this.getAll = function() {
return $http.get('/allphotos').then(function(response) {
// ^ 'getAll' returns Original Promis comes from '$http'
return response.data;
// ^ here we resolve 'response.data'
}, function(err) {
console.log('error is:' + err.err)
});
}
});
And now in controller do:
app.controller('ctrl',function ($scope, httpService) {
httpService.getAll().then(function(data) {
$scope.data = data;
}, function error(err) {
console.log('error is:' + err.err)
});
}
