如何在路由或控制器中访问 RESTAdapter 的主机和命​​名空间? [英] How do you access RESTAdapter's host and namespace inside a route or controller?

问题描述

我在一些控制器和路由中使用了一些自定义的 AJAX 请求，例如:

I have a few custom AJAX requests that I use inside of some controllers and routes, for example:

 var loginRoute = Ember.Route.extend({

   actions: {

     submitLogin: function(user, pass) {

       var data = { username: user, password: pass };

       Ember.$.post('http://192.168.2.10/api/v1/login', data).then();
     }

   }
 });

这很好用，但在开发时我可能有不同的 IP(例如更改路由器)我希望能够访问我在扩展 RESTAdapter 时定义的 URL(主机 + 命名空间)，这样我只需更改 host 和/或 namespace 一次，而不是在我执行自定义 ajax 请求的每个地方.

This works fine, but while developing I may have a different IP (e.g. changing routers) and I'd like to be able to access the URL(host + namespace) I defined when I extended the RESTAdapter so that I only have to change the host and/or namespace once, instead of every place where I do a custom ajax request.

 App.ApplicationAdapter = DS.RESTAdapter.extend({
   host: 'http://192.168.2.10',
   namespace: 'api/v1'
 });

推荐答案

原来你可以通过 this.store.adapterFor('application')

新的 submitLogin 方法可能如下所示:

The new submitLogin method could look like this:

 submitLogin: function(user, pass) {

   var data = { username: user, password: pass },
       host = this.store.adapterFor('application').get('host'),
       namespace = this.store.adapterFor('application').namespace,
       postUrl = [ host, namespace, 'login' ].join('/'); // http://192.168.2.10/api/v1/login

   Ember.$.post(postUrl, data).then();
 }
