And non of them solved my problem.

I would like to use Giant Bombs API: http://www.giantbomb.com/api/

Yes i took a look at the forum posts nothing works.

$http({
        method: 'JSONP',
        url: 'http://www.giantbomb.com/api/game/3030-4725/',
        params: {
            api_key: $rootScope.api_key,
            format: 'jsonp',
            callback: 'JSON_CALLBACK'
        }
    }).then(function (data) {
        $scope.data = data;
        console.log($scope.data)
    });

Error

Uncaught SyntaxError: Unexpected token :

Could someone give me a hint?

Because its really frustrating, I even wrapped the data with JSON_CALLBACK() same result


Solution

  • The reason of this is, that angular requires service returns jsonp, but it doesn't

    Your code does this request:

    http://www.giantbomb.com/api/game/3030-4725/?json_callback=angular.callbacks._0&format=jsonp
    

    And in network console you can see the response:

    {"error":"'jsonp' format requires a 'json_callback' arguement","limit":0,"offset":0,"number_of_page_results":0,"number_of_total_results":0,"status_code":103,"results":[]}
    

    so the parameter for callback should be named: json_callback, not just callback.

    $http({
            method: 'JSONP',
            url: 'http://www.giantbomb.com/api/game/3030-4725/',
            params: {
                format: 'jsonp',
                json_callback: 'JSON_CALLBACK'
            }
        })
    

    After that I can see in response error about api key - this will probably be ok in your instance. So I uppose you will get correct JSONP

    http://www.giantbomb.com/api/game/3030-4725/?json_callback=angular.callbacks._0&format=jsonp
    
    {"error":"Invalid API Key","limit":0,"offset":0,"number_of_page_results":0,"number_of_total_results":0,"status_code":100,"results":[]}
    

    The other problem would be that your function in then doesn't get data directly, but response, which is objects which carry data, so:

    .then(function (response) {
            $scope.data = response.data;
            console.log(response.data)
        });
    

    The last one recommendation, do not use $scope in controllers, rather use "controller as" syntax.
