This time I will show you how to use mpvue to build a small program, and what are the precautions for building a small program with mpvue. The following is a practical case, let's take a look.
mpvue is a front-end framework that uses Vue.js to develop small programs (an open source project of Meituan). The framework is based on the core of Vue.js, and mpvue has modified the runtime and compiler implementations of Vue.js so that it can run in a small program environment, thereby providing convenience for small programs. Program development introduces a complete Vue.js development experience.

var fly=new Fly(); //创建fly实例
//添加拦截器
fly.interceptors.request.use((config,promise)=>{
//给所有请求添加自定义header

return config;
})
