一行命令, 静态json变身api

作为一个前端开发者, 你可以会遇到没有测试数据的尴尬, 而这次我们用json-server, 优雅的解决这个问题

效果

关于 json-server

json-server

全局安装方式:

npm install -g json-server

使用方式: 如果有一个名为douyu.json的文件, 它的启动命令为

json-server --watch douyu.json

启动界面

json-server最外层json的值, 默认只支持数组和对象

使用axios发出请求

axios.get("http://localhost:3000/data")
.then(res=> {    return (res.data.rl)
})
