javascript - $resource 无法从 json 获取数组

Question

我想从服务器(java)获取数组对象。下面是 Angular 方法:

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

        var authors = authorResource.query(function() {
            console.log(authors);
        }).$promise.then( function(){
                deferred.resolve( "Adding book have gone correctly." );
            }, function(){
                deferred.reject("Error during adding new book.");
            });
    }

在控制台 Firebug 中我看到这个:[{"author_id":7,"author":"Dan Brown"}] 但authors数组是空的。你能告诉我为什么吗？

您需要将作者分配给返回的服务器数据。

authorResource.query(function() {
        console.log(authors);
    }).$promise.then( function(data){
            authors = data;
            deferred.resolve( "Adding book have gone correctly." );
        }, function(){
            deferred.reject("Error during adding new book.");
        });
