API接口：

API接口是什么？

API全称是：Application Programming Interface，即：应用程序接口。开发人员可以使用这些API接口进行编程开发，而又无需访问源码，或理解内部工作机制的细节。

比较常见的现实场景是，在开发安卓应用时需要使用到安卓系统提供的API，在进行Windows桌面应用开发时需要用到微软系统提供的API，在进行微信小程序开发时可使用微信开放接口API。

更为常见的是，API接口很可能是远程的服务端API，其背后采用Java、PHP、C#、Pyhon、C/C++、Ruby、Scala等一种或多种后端语言开发搭建，提供了数据存储、通讯、各类服务等功能。一般是使用HTTP协议进行通讯，使用JSON格式序列化返回接口结果和数据。

API接口的地位与作用

API接口是项目开发过程中必要的组成部分之一，是客户端应用与服务端应用通信和桥梁。

除此之外，从专业角度来说，API不仅代表着接口本身，还蕴含了服务端的整体系统架构、数据存储、服务端管理、第三方系统的整合等，只是对外看来，表现出来的是API接口。

可以说，API接口直接使用方是客户端应用，地位是客户端与服务端之间的通信桥梁，是信息化的桥梁，所担负的作用是把业务功能通过接口服务形式具体化，为应用编程开发提供技术支持。
