Angular 在 http.get 函数 returns 之前调用的成功函数

Angular success function called before http.get function returns

我有一个 angular 控制器,它发出 HTTP GET 请求并承诺 return,调用错误函数成功。我现在的代码有时会在 GET 请求 return 之后执行成功函数,有时会在它之前执行。我的承诺处理有什么问题吗?需要注意的是,有时 http GET 甚至没有被调用(或者至少它的断点)并且成功函数无论如何都会发生。这是我的代码:

.controller('CheckOutCtrl', ['$scope', '$http', function($scope, $http) {
    //Controller for checkout feature
    $scope.owner = "Unclaimed"; //Default owner
    $scope.endDate = "";
    $scope.unclaimed = true;
    $scope.showpopup = false; //Should we show the popup that checkout is successful or returned
    $scope.currentOwner = false; //Show return date
    $scope.popuptext = "";

    $scope.checkOut = function(){ //Extends or creates a check out
        $http.get("/checkout/extend/code/" + code + "/username/" + userName).then(
            function success(response, status, headers, config) {
                console.log("Checked out or extended");
                $scope.showpopup = true;
                $scope.currentOwner = true;
                $scope.popuptext = response.data; //Show airport checked out until or error
                console.log($scope.popuptext);
                init(); //Update current owner
            },
            function error(response, status, headers, config) {
                $scope.error = response;
                console.error("Check out error:", response);
            }
        );
    };
}

我发现这是因为 Angular 将 GET 请求缓存了一段时间,并且正在使用我的请求的缓存版本。
