Question

我有一个发出$ HTTP.GET请求的服务，起初我试图访问对象$$状态，但是里面的值是未定义的，所以我在这里红了一下promises和异步调用： http://blog.ninja-squad.com/2015/05/28/angularjs-promises/

我红了所有的东西后我再次尝试按照指导，但它仍然不适合我:-(，请指教，我想访问值对象。

service:
function ConnectMe($http) {

function OnAction() {

    this.create = function (search, key) {
        return $http.get("https://www.tastekid.com/api/similar?q=" + search + "&verbose=1&k=" + key).then(function (response) {
            return response.data;
        });

    };
}

var connection = new OnAction();

return function () {
    return connection;
};
}


controller:
function TasteConroller($scope, ConnectMe) {
$scope.apiKey = "https://www.tastekid.com/api/similar?q=" + $scope.UserPick + "&verbose=1&k=254357-MatureAm-A31YEAIX";
$scope.UserPick = "red+hot+chili+peppers";
$scope.Key = "254357-MatureAm-A31YEAIX";
var srv = ConnectMe();

srv.create($scope.UserPick, $scope.Key).then(function(data) {
    $scope.results = data;
}), function() {
    $scope.error = 'unable to get the ponies';
};

console.log($scope.results);

您的服务代码看起来有点可疑。我通常会创建这样的服务;

function ServiceFunc( $http, $q ){
    return {
        OnAction: function( search, key ){ 
            return $http.get(...)
                   .then( function( rsp ){ return rsp.data.foo })
                   .catch( function( err ){ $q.reject( err )})
    }
}

我认为你可能有更深层次的功能，而你实际上并没有调用它。

Angular.js承诺$ http.get
