如何通过AngularJS $资源

我试图从openweathermap.org（JSON）检索天气数据检索外部资源（JSON），

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

在你的情况下，weatherResult变量是一个promise对象。

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

所以你的情况的代码应该是：：您可以通过在控制器中得到$ HTTP调用的返回值

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

有关$资源的更多信息，你可以随时参考docs 。返回部分将对此进行更多启发。
