AngularJS $http 和 $resource [英] AngularJS $http and $resource

问题描述

我有一些网络服务要调用.$resource 或 $http，我应该使用哪个?

I have some web services that I want to call. $resource or $http, which one should I use?

$resource:https://docs.angularjs.org/api/ngResource/service/$resource

$http:https://docs.angularjs.org/api/ng/service/$http

读完上面两个 API 页面后，我迷路了.

After I read the two above API pages I am lost.

您能否用简单的英语向我解释一下有什么区别，我应该在什么情况下使用它们?如何构建这些调用并将结果正确读入 js 对象?

Could you please explain to me in plain English what is the difference and in what situation should I use them? How do I structure these calls and read the results into js objects correctly?

推荐答案

$http 用于通用 AJAX.在大多数情况下，这就是您将要使用的.使用 $http，您将手动进行 GET、POST、DELETE 类型调用并处理对象他们自己回来.

$http is for general purpose AJAX. In most cases this is what you'll be using. With $http you're going to be making GET, POST, DELETE type calls manually and processing the objects they return on your own.

$resource 包装 $http 以在 RESTful Web API 场景中使用.

$resource wraps $http for use in RESTful web API scenarios.

笼统地说:RESTful Web 服务将是一种具有一个数据类型端点的服务，该数据类型基于 GET、POST、PUT、DELETE 等.所以使用$resource，你可以调用GET 来获取资源作为 JavaScript 对象，然后更改它并使用 POST 将其发送回，甚至使用 DELETE 将其删除.

Speaking VERY generally: A RESTful web service will be a service with one endpoint for a data type that does different things with that data type based on HTTP methods like GET, POST, PUT, DELETE, etc. So with a $resource, you can call a GET to get the resource as a JavaScript object, then alter it and send it back with a POST, or even delete it with DELETE.

...如果这是有道理的.

... if that makes sense.
