AngularJS SyntaxError: Unexpected token in JSON at position 0

Question

I'm trying to do a pagination using angularJS + codeigniter, I have a controller called by "Cursos" and a function called by "api" to get the data

the function api code:

    $currentPage = $this->uri->segment(3); # Pagina atual
    $sizePage = $this->uri->segment(4); # Tamanho da pagina (num de itens que serão listados)
    $searchText = $this->uri->segment(5); # Argumento de pesquisa
    $offset = ($currentPage - 1) * $sizePage; // Obter o offeset da pagina para obter os resultados paginados
    $r = $this->cursos->obterCursos(0,$nomeCurso=null,"array",$sizePage,$offset);
    $array = array('DadosDosCursos' => $r, 'totalCount' => count($r));
    header('Content-Type: application/json');


    return $this->output
    ->set_content_type('application/json')
    ->set_status_header(200)
    ->set_output(json_encode($array));

    exit(json_encode($array));

and the result looks ok:

{"DadosDosCursos":[{"i_imc_ID":"2","i_imc_cargaHoraria":"40 horas","i_imc_categoriaIDS":"1,2","i_imc_dataCreated":"2017-02-20 11:36:36","i_imc_etapasAprendizagem":"Etapa 1\r\netapa 2","i_imc_imagemLogo":"web-design-criacao-de-sites_04042016162740.png","i_imc_imagemMiniatura":"imagepress-impressos-profissionais_05012016115837.jpg","i_imc_metaDescriptions":"meta description","i_imc_metaTags":"meta tags","i_imc_nome":"Nome do curso 2","i_imc_softwaresIDS":"1","i_imc_status":"1","i_imc_subtitulo":"Subtitulo aqui","i_imc_textoApresentacao":"Apresenta\u00e7\u00e3o"},{"i_imc_ID":"1","i_imc_cargaHoraria":"80 horas","i_imc_categoriaIDS":null,"i_imc_dataCreated":"2017-02-17 00:00:00","i_imc_etapasAprendizagem":"Etapa 1","i_imc_imagemLogo":"modelagem-com-3ds-max--v-ray--photoshop_04042016163311.png","i_imc_imagemMiniatura":"imageweb-criacao-de-sites_14122015100956.jpg","i_imc_metaDescriptions":"meta description","i_imc_metaTags":"meta tags","i_imc_nome":"Curso de desenvolvimento de sistemas","i_imc_softwaresIDS":"1","i_imc_status":"0","i_imc_subtitulo":"subtitulo","i_imc_textoApresentacao":null}],"totalCount":2}

my angularJS controller:

app.controller('activityTableCtrl', function($scope, $http) {

    $scope.currentPage = 1;
    $scope.totalItems = 0;
    $scope.pageSize = 10;
    $scope.searchText = '';
    getData();

    function getData() {
    $http.get('http://localhost/estudo/site/cursos/api/' + $scope.currentPage + '/' + $scope.pageSize
    //$http.get("../assets/api/database.json"
        )
        .then(function(data) {




            $scope.activity = [];
            $scope.totalItems = data.totalCount;
            $scope.startItem = ($scope.currentPage - 1) * $scope.pageSize + 1;
            $scope.endItem = $scope.currentPage * $scope.pageSize;

            if ($scope.endItem > $scope.totalCount) {
                $scope.endItem = $scope.totalCount;
            }

            angular.forEach(data.DadosDosCursos, function(temp){
                $scope.activity.push(temp);
            });

        });
    }

    $scope.pageChanged = function() {
        getData();
    }
    $scope.pageSizeChanged = function() {
        $scope.currentPage = 1;
        getData();
    }
    $scope.searchTextChanged = function() {
        $scope.currentPage = 1;
        getData();
    }
 })

I'm getting this error on console.log SyntaxError: Unexpected token in JSON at position 0

I tried to load from another URL with JSON and everything was done well

This may or may not answer your question but it would be better if you just replaced this loop:

angular.forEach(data.DadosDosCursos, function(temp){
                $scope.activity.push(temp);
            });

With:

$scope.activity = data.DadosDosCursos

Because you are already emptying your $scope.activity array in the beginning of then and you are not modifying any structure of entries within data.DadosDosCursos ;)
