问题描述

我对 angularJS 很陌生.我正在搜索从 RESTful API 访问服务，但我没有任何想法.我该怎么做?

I am very new to angularJS. I am searching for accessing services from RESTful API, but I didn't get any idea. How can I do that?

推荐答案

Option 1: $http service

AngularJS 提供了 $http 服务正是您想要的:使用 JSON 向 Web 服务发送 AJAX 请求并从它们接收数据(这非常适合与 REST 服务对话).

Option 1: $http service

AngularJS provides the $http service that does exactly what you want: Sending AJAX requests to web services and receiving data from them, using JSON (which is perfectly for talking to REST services).

举个例子(取自 AngularJS 文档并稍作修改):

To give an example (taken from the AngularJS documentation and slightly adapted):

$http({ method: 'GET', url: '/foo' }).
  success(function (data, status, headers, config) {
    // ...
  }).
  error(function (data, status, headers, config) {
    // ...
  });

选项 2:$资源服务

请注意，AngularJS 中还有另一个服务，$resource service 以更高级的方式提供对 REST 服务的访问(示例再次取自 AngularJS 文档):

Option 2: $resource service

Please note that there is also another service in AngularJS, the $resource service which provides access to REST services in a more high-level fashion (example again taken from AngularJS documentation):

var Users = $resource('/user/:userId', { userId: '@id' });
var user = Users.get({ userId: 123 }, function () {
  user.abc = true;
  user.$save();
});

选项 3:重新定义

此外，还有第三方解决方案，例如Restangular.请参阅其文档，了解如何使用它.基本上，它更具声明性，并从您那里抽象出更多细节.

Option 3: Restangular

Moreover, there are also third-party solutions, such as Restangular. See its documentation on how to use it. Basically, it's way more declarative and abstracts more of the details away from you.
