javascript - Angular Controller 不控制台记录数据。然而，Service 正在传递数据。

Question

我的后端已链接到该服务。当我在 Controller 上调用函数时，它会在服务中执行该函数，并控制台记录数据。从服务到 Controller 的数据是通过 Promise 传递的。我正在获取适当的数据。但是，为了将数据绑定(bind)到我的示波器上，我需要 Controller 上的数据。当我通过控制台记录数据时，控制台日志未定义。我不确定我做错了什么。

Controller

"use strict";

app.controller("weatherCtrl", function($scope, weatherService) { //START APP

// ***********************************************
// *************** GET LATEST DATA ***************
// ***********************************************  
    $scope.getTodaysWeather = function() { //OPEN FUNCTION
        weatherService.getWeatherData().then(function(data) {
            console.log("Weather Control", data);
            // $scope.todaysWeather = data;

        });
    }; //CLOSE FUNCTION

    $scope.getTodaysWeather(); //INVOKE THE FUNCTION

}); //CLOSE APP

服务

"use strict";

app.service("weatherService", function($http, $q) { //START APP

// ***********************************************
// *************** GET LATEST DATA ***************
// ***********************************************
    this.getWeatherData = function() { //OPEN FUNCTION
        var defer = $q.defer(); //promise 
        $http.get("/app/weather/weatherData")
        .success(function(response) { //callback for resolve
            console.log("Main Service Data", response); 

            var weatherDataObj = response.report;
            var weatherDataArray = [];

            for (var key in weatherDataObj) {
                weatherDataArray.push({
                    max_temp: weatherDataObj.max_temp,
                    min_temp: weatherDataObj.min_temp
                });
            }
            console.log("weatherDataArray from Service", weatherDataArray);
            defer.resolve(); //successful promise
        })
        .error(function(err) {
            defer.reject(err);
        });
        return defer.promise; //return promise "q"
    }; //CLOSE FUNCTION

}); //CLOSE APP

            defer.resolve(weatherDataArray); //YOU NEED TO RESOLVE THE DATA
        })
        .error(function(err) {

        });
        return defer.promise; //return promise "q"
    }; //CLOSE FUNCTION

}); //CLOSE APP
