AngularJS Poller抛出

Question

我正在尝试为一个应用程序设置轮询，并且我有一个实现，它在最初运行的地方执行最小值，获得第一个响应，但是在调用$timeout时失败并抛出一个异常(参见下面)。我不明白为什么它不能正常投票，它看起来应该工作，API说$timeout需要一个函数.有什么想法吗？

如果我注释掉第65行$timeout(.)，我不会得到错误。

异常

Error: [$http:badreq] Http request configuration must be an object.  Received: function ()
http://errors.angularjs.org/1.4.7/$http/badreq?p0=function%20()
    at angular.js:68
    at $http (angular.js:10189)
    at scoreboard-service.js:65
    at processQueue (angular.js:14745)
    at angular.js:14761
    at Scope.$eval (angular.js:15989)

    at Scope.$apply (angular.js:16097)
    at done (angular.js:10546)
    at completeRequest (angular.js:10744)

轮询工厂和.run中的初始化。

轮询工厂

/**
 *
 */
.factory('ScoreboardPollFactory', ['ConfigSettings', 'ScoreboardFactory', '$http', '$timeout',
    function (ConfigSettings, ScoreboardFactory, $timeout) {

        var pollingTimeout = ConfigSettings.pollingTimeout;
        var data = {response: {}, calls: 0};

        var poll = function (courtId) {

            var courtId = 1; // testing app so hardcoded for now till API is ready

            console.log(ScoreboardFactory); // debug: has correct factory object, and never makes it back here after hitting $timeout

            ScoreboardFactory.getCourtScore(courtId).then(function (response) {
                data.response = response.data
                data.calls++;

                console.log(response); // debug: contains first response
                console.log(data);
                console.log(poll); // debug: outputs poll function

                $timeout(function() { // <-- this is line 65 from error
                    poll(courtId);
                }, pollingTimeout);
            });
        }

        poll();

        return {
            data: data
        };
    }])

/**
 *
 */
.run(['ScoreboardPollFactory', function (ScoreBoardPollFactory) {
}]);

这是你的问题(排好队，这样你就可以看到发生了什么事)

.factory('ScoreboardPollFactory',
            ['ConfigSettings', 'ScoreboardFactory', '$http', '$timeout',
    function (ConfigSettings,   ScoreboardFactory,   $timeout) {

您将$http服务注入为$timeout。

我建议使用像ng-注释这样的构建工具来创建依赖注入数组，从而避免遇到类似的问题。
