HomeBackend DevelopmentPHP Tutorial如何判断访问来源?

一个后台系统,既有面向app的json输出,也有面向pc的html输出。
如何判断访问的来源?
通过php代码自动判断,还是让前端带上参数判断,还是使用不同的url。这些都可以实现,一般是采用哪种方法的,想看下经验之谈。


回复讨论(解决方案)

我个人一般是让前端带上参数判断。

怎么方便怎么来
前端方便加,就加个来源,后端自己也可以获取user_agent

url带上标示处理

PC 也可能需要 json输出(比如 ajax 应用)
所以不能做自动识别,应显式的指定数据类型

如果app过来的都以json格式输出的话 我觉得可以在app过来的请求头中加上某个标识

API 通常以 REST 方式工作,url 一般写作
服务器/资源路径/资源名.后缀
常见 后缀 为 html、xml、json(最常用的可省略),是很容易检查的
