我一直在这一天大部分时间都在猛烈抨击,并且无法将$ scope.weatherData解析为未定义的任何内容:(
这是我的view1控制器:
'use strict';
angular.module('myApp.view1', ['ngRoute'])
.config(['$routeProvider', function ($routeProvider) {
$routeProvider.when('/view1', {
templateUrl: 'view1/view1.html',
controller: 'View1Ctrl',
resolve: {
weatherData: ['$q', 'weatherSvc', function ($q, weatherSvc, options) {
var lat = 0;
var lon = 0;
var deferred = $q.defer();
navigator.geolocation.getCurrentPosition(
deferred.resolve,
deferred.reject,
options);
deferred.promise.then(function (position) {
lat = position.coords.latitude;
lon = position.coords.longitude;
console.log('lat:' + lat + ' lon:' + lon);
var data = weatherSvc.query(lat, lon);
console.log(data); // <-- data is a promise at this point but log has already fired in the controller
data.then(function(data){
console.log(data.data);
return data;
});
});
}]
}
});
}])
.controller('View1Ctrl', ['$scope', 'weatherData', function ($scope, weatherData) {
$scope.weatherData = weatherData;
console.log(weatherData);
}]);
这是weatherSvc
angular.module('myApp.services', [])
.factory('weatherSvc', ['$http', function ($http) {
'use strict';
function rangeLimit(value, min, max) {
value = (value >= min) ? value : min;
value = (value <= max) ? value : max;
return value;
}
var sdo = {
query: function (lat, lon, refresh) {
// validations
refresh = refresh || false;
// valid lat = -90...90
// valid lon = -180...180
lat = rangeLimit(lat, -90, 90);
lon = rangeLimit(lon, -180, 180);
var promise = $http({
method: 'GET',
url: 'http://api.openweathermap.org/data/2.5/forecast/daily?lat=' + lat + '&lon=' + lon + '&mode=json'
});
promise.success(function (data, status, headers, conf) {
return data;
});
return promise;
}
};
return sdo;
}]);
获取位置,向天气服务器发出api get请求,但$ scope.weatherData永远不会被填充。
