问题描述
我正在尝试一个与Ember对话的API的Loopback。
I'm trying out Loopback for an API that will talk to Ember.
Ember需要将JSON包含在keys中,例如对于一个帐户:
Ember requires JSON to be contained in 'keys', e.g. for an account:
{ account:
{ domain: 'domain.com',
subdomain: 'test',
title: 'test.domain.com',
id: 1
} }
我在Google小组上发现了一些有关如何更改响应的建议,以便Ember将使用afterRemote钩子接收它。
I've found some advice on the Google group about how to alter the response so that Ember will receive it, using afterRemote hooks.
例如。在我的模型/ account.js中:
E.g. in my models/account.js:
module.exports = function(Account) {
Account.afterRemote('**', function (ctx, account, next) {
if(ctx.result) {
if(Array.isArray(ctx.result)) {
ctx.res.body = { 'accounts': account };
} else {
ctx.res.body = { 'account': account };
}
}
console.log(ctx.res.body);
next();
});
};
我看到响应是应该在控制台中的。但是在localhost的JSON输出:3000 / api / accounts不显示更改的JSON对象。
I see that the response is as it should be in the console .. however the JSON output at localhost:3000/api/accounts does not show the altered JSON object.
在Loopback中更改JSON响应/请求的正确方法是什么?
What is the correct way to alter the JSON response / requests in Loopback?
理想情况下,可以将其应用于所有模型。
Ideally in a general way so it can be applied to all Models.
推荐答案
通过使用 DS.RESTAdapter
与 DS.JSONSerializer
像这样:
// app/adapters/application.js
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
host: 'http://loopback-api-host',
namespace: 'api',
defaultSerializer: 'JSONSerializer'
});
在Ember Data中,用于与后端数据存储进行通信的逻辑位于适配器中,Ember Data适配器有一些关于REST API应该如何看待的内置假设,如果您的后端约定与这些假设不同,Ember Data可以轻松更改其功能是通过交换或扩展默认适配器。
"In Ember Data, the logic for communicating with a backend data store lives in the Adapter. Ember Data's Adapter has some built-in assumptions of how a REST API should look. If your backend conventions differ from these assumptions Ember Data makes it easy to change its functionality by swapping out or extending the default Adapter."
