Angular ui-router通过resolve获取异步数据

Question

我想显示一个表格,其中包含与编辑项目相对应的数据.我ui-router用于路由.我定义了一个州:

myapp.config(function($stateProvider) {

    $stateProvider.
    .state('layout.propertyedit', {
        url: "/properties/:propertyId",
        views : {
            "contentView@": {
                templateUrl : 'partials/content2.html', 
                controller: 'PropertyController'
            }
        }
    });

在PropertyController,我想设置$scope.property来自以下呼叫的数据(Google Cloud Endpoints):

    gapi.client.realestate.get(propertyId).execute(function(resp) {
        console.log(resp);
    });

我不知道是否可以使用,resolve因为数据是异步返回的.我试过了

    resolve: {
        propertyData: function() {
            return gapi.client.realestate.get(propertyId).execute(function(resp) {
                console.log(resp);
            });
        }
    }

第一个问题,propertyId未定义.你怎么得到propertyId的url: "/properties/:propertyId"？

基本上我想设置$scope.property在PropertyController向resp通过异步调用返回的对象.

编辑:

myapp.controller('PropertyController', function($scope, , $stateParams, $q) {

    $scope.property = {};

    $scope.create = function(property) {
    }

    $scope.update = function(property) {
    }

function loadData() {
    var deferred = $q.defer();

    gapi.client.realestate.get({'id': '11'}).execute(function(resp) {
        deferred.resolve(resp);
    });

    $scope.property = deferred.promise;
}

});

您需要阅读文档以求解决.Resolve函数是可注入的,您可以使用$stateParams从路由中获取正确的值,如下所示:

resolve: {
    propertyData: function($stateParams, $q) {
        // The gapi.client.realestate object should really be wrapped in an
        // injectable service for testability...

        var deferred = $q.defer();

        gapi.client.realestate.get($stateParams.propertyId).execute(function(r) {
            deferred.resolve(r);
        });
        return deferred.promise;
    }
}

最后,一旦解析,解析函数的值可在控制器中注入:

myapp.controller('PropertyController', function($scope, propertyData) {

    $scope.property = propertyData;

});
