API介面：

API介面是什麼？

API全稱是：Application Programming Interface，即：應用程式介面。開發人員可以使用這些API介面進行程式設計開發，而又無需訪問原始碼，或理解內部工作機制的細節。

比較常見的現實場景是，在開發安卓應用時需要使用到安卓系統提供的API，在進行Windows桌面應用開發時需要用到微軟系統提供的API，在進行微信小程式開發時可使用微信開放介面API。

想了解API介面，這一篇夠了

更為常見的是，API介面很可能是遠端的服務端API，其背後採用Java、PHP、C#、Pyhon、C/C++、Ruby、Scala等一種或多種後端語言開發搭建，提供了資料儲存、通訊、各類服務等功能。一般是使用HTTP協議進行通訊，使用JSON格式序列化返回介面結果和資料。

API介面的地位與作用

API介面是專案開發過程中必要的組成部分之一，是客戶端應用與服務端應用通訊和橋樑。

除此之外，從專業角度來說，API不僅代表著介面本身，還蘊含了服務端的整體系統架構、資料儲存、服務端管理、第三方系統的整合等，只是對外看來，表現出來的是API介面。

可以說，API介面直接使用方是客戶端應用，地位是客戶端與服務端之間的通訊橋樑，是資訊化的橋樑，所擔負的作用是把業務功能透過介面服務形式具體化，為應用程式設計開發提供技術支援。
