AngularJs-路由解析器链接

Question

每当使用路由解析器在路径中传递了dropDraft时，我都试图删除草稿数据并加载原始数据。

我的用例是删除承诺必须在获取数据之前完成。

Delete和Get正在运行paralley。如何制作

resolve: {
   data: [
          '$route',
          '$q',
          'service1',
          function ($route, $q, service1) {
            var deferred = $q.defer();
            var getDataPromise = service1.getData($route.current.params); 
            if ($route.current.params.deleteDraft) {
               var deleteDraftPromise = service1.deleteDraft($route.current.params.id);
               deleteDraftPromise.then(function () {
                     getDataPromise.then(function (resultData) {
                        deferred.resolve(resultData);
                     });
               });
            } 
            else {
                     getDataPromise.then(function (resultData) {
                           deferred.resolve(resultData);
                      });
                 }
            return deferred.promise;
            }
      ]

一个接一个地解决

resolve: {
data: ['$route', '$q', 'service1', function ($route, $q, service1) {
    var deferred = $q.defer();
    if ($route.current.params.deleteDraft) {
        service1.deleteDraft($route.current.params.id, function (res) {
            service1.getData($route.current.params, function (argument) {
                deferred.resolve(argument);
            });
        });
    } else {
        service1.getData($route.current.params, function (argument) {
            deferred.resolve(argument);
        });
    }
    return deferred.promise;
}]

}
