这篇文章来分享下api接口对接如何实现,还有源码,希望对新手有所帮助。

api接口对接如何实现,php如何对接api

什么是API?

我的回答:API( 应用程序编程接口):一般来说,这是一套明确定义的各种软件组件之间的通信方法。

什么是API?我们不妨用一个小故事展示出来:

研发人员A开发了软件A,研发人员B正在研发软件B。

有一天,研发人员B想要调用软件A的部分功能来用,但是他又不想从头看一遍软件A的源码和功能实现过程,怎么办呢?

研发人员A想了一个好主意:我把软件A里你需要的功能打包好,写成一个函数;你按照我说的流程,把这个函数放在软件B里,就能直接用我的功能了!

其中,API就是研发人员A说的那个函数。

进一步解释:

比如c语言的fopen()函数来打开一个文件,感觉非常简单。

但是操作到底层是非常复杂的,打开文件需要扫描硬盘,找到我文件位置,然后读取部分数据,并放进i/o缓存中,放进内存。

这些数据都是0,1序列,还要对照ASCII表或者unicode表翻译成字符,再在显示器上显示出来。如果这个过程让程序员来完成,简直就是个噩梦。不可能的事。

怎么办呢?

操作系统就想了一个很好的办法。它预先把复杂的操作写在一个函数里面,编译成一个组件(一般是动态链接库)程序员只需要简单的调用这些函数就可以用完成复杂的工作。

这些封装好的函数就叫做API。

参考:如何对接伪原创API 更加通俗讲:别人写好的代码,或者编译好的程序,提供给你使用,就叫做api。

因为你使用了别人的代码( 或者程序)中的某个函数,类,对象,就叫做使用了某个api。
