Question

我正在尝试从openweathermap.org（JSON）中检索天气数据，

这是我的控制器代码：

weatherApp.controller('forecastController', ['$scope', '$log', 'forecastService', function($scope, $log, forecastService) {

    $log.info(forecastService.getWeather('Davao City', '5'));

}]);

这是我的服务代码：

weatherApp.service('forecastService', [ '$resource', '$sce', function 
 ($resource, $sce) {

    this.getWeather = function (city, numDays){

        var key = 'b3cc85931eae059522f3a9b8c5260f6e';

        var link = function() {
           return $sce.trustAsResourceUrl("http://api.openweathermap.org/data/2.5/forecast/");
        };

        var weatherAPI = $resource(link(), { callback: "JSON_CALLBACK" }, { get: { method: "JSONP" }});

        var weatherResult = weatherAPI.get({ q: city, cnt: numDays, appid: key });

        return weatherResult;
    };

}]);

Kept on getting this error, please help T_T

在您的情况下，weatherResult变量是一个promise对象。您可以通过以下方式获取控制器中的$ http调用返回值：

  myPromiseReturningServiceFunctionCall.$promise(successFunction(data) {
          // Do something with the data.
      }, errorFunction(error) {
      }
   )

所以在你的情况下代码应该是：

forecastService.getWeather('Davao City', '5').$promise(
      successFunction(data) {
          // Do something with the data.
      }, errorFunction(error) {
      })

有关$ resource的更多信息，您可以随时参考docs。返回部分将为您提供更多信息。
