2-4 vue- cli数据mock

一、新建mock文件夹

二、配置vue.config.js

const data = require("./mock/index.json");
module.exports = {
    devServer: {
        port: 8080,
        before(app) {
            app.get("/cart", (req, res) => {
                res.json(data);
            });
        }
    }
}

三、请求数据

mounted(){
    axios.get("/cart").then(res=>{
      console.log(res)
    })
}
