Backbone.js中的自定义RESTapi响应

Question

My REST api returns data in json in following format for `/api/users`:
{
    "objects":[
        {"User":{"id":"1","created":"2013-02-13 09:22:42","modified":"2013-02-13 09:22:42","username":"[e-mail]","role":"admin"}},
        {"User":{"id":"2","created":"2013-02-13 09:22:55","modified":"2013-02-13 09:22:55","username":"[e-mail]","role":"analyst"}},
        {"User":{"id":"3","created":"2013-02-13 09:23:02","modified":"2013-02-13 09:23:02","username":"[e-mail]","role":"moderator"}},
        {"User":{"id":"4","created":"2013-02-13 09:23:10","modified":"2013-02-13 09:23:10","username":"[e-mail]","role":"representative"}}
        ],
    "meta":
        {"page":1,"pageCount":1,"prevPage":false,"nextPage":false,"limit":20,"count":4,"sort":null,"direction":null}
}

对于/api/users/{id}，它以以下格式返回数据：

{"User":{"id":"1","created":"2013-02-13 09:22:42","modified":"2013-02-13 09:22:42","username":"[e-mail]","role":"admin"}

如何将其与Backbone.js Collection和Model集成？我知道Backbone.js希望api返回对象dict数组或纯对象dict-有办法改变它吗？

是的。您可以覆盖model.parse或collection.parse。例如：

var UserCollection = Backbone.Collection.extend({
                model: User, 
                url: '/api/users',
                parse: function(response) {
                        // process response.meta when necessary...
                        return response.objects;
                    });
                }
            });
var UserModel = Backbone.Model.extend({
                 //...
                 parse: function(response) {
                        return response.User;
                    });
                }
            });
