mpvue中使用flyjs全局拦截的实现代码

npm install flyio

var Fly=require("flyio/dist/npm/wx")
var fly=new Fly

// 请求拦截
fly.interceptors.request.use((request)=>{
 
 request.body.appId = 'xxx'
  // 用户的openId在获取之后添加到全局变量中如果存在，我们将它添加到请求参数里面
 let openId = Vue.prototype.globalData.openId;
 if(openId){
  request.body.openId = openId
 }
})

// 响应拦截
fly.interceptors.response.use(
 (response) => {
 
 
 },
 (err) => {
  //发生网络错误后会走到这里
  //return Promise.resolve("ssss")
  wx.hideLoading();
  wx.showToast({
   title:'网络不流畅，请稍后再试！',
   icon:'none',
  });
 
 })

// 将fly挂载在Vue的原型上
Vue.prototype.$flyio = fly

const Fly = require("flyio/dist/npm/wx")
const fly = new Fly
Vue.prototype.$http = fly;
 
fly.interceptors.request.use((request) => {
 //给所有请求添加自定义header
 if (api.Get('token')) {
  request.timeout = 30000,
   request.headers = {
    "content-type": "application/json",
    "cld.stats.page_entry": api.Get('scene'),
    "version": store.state.version,
    "token": api.Get('token')
   }
  wx.showLoading({
   title: "加载中",
   mask: true,
  });
  return request;
 } else {
  fly.lock();//锁住请求
  return Public.Load().then(res => {
   request.timeout = 30000,
    request.headers = {
     "content-type": "application/json",
     "cld.stats.page_entry": api.Get('scene'),
     "version": store.state.version,
     "token": api.Get('token')
    }
   wx.showLoading({
    title: "加载中",
    mask: true,
   });
    //等待token返回之后在解锁，
   fly.unlock();
   return request;//继续之前的请求，
  })
 }
})
 
fly.interceptors.response.use(
 (response) => {
  wx.hideLoading();
  return response
 },
 (err) => {
  wx.hideLoading();
  if (err.status == 0) {
   return "网络连接异常"
  } else if (err.status == 1) {
   return "网络连接超时"
  } else if (err.status == 401) {
   return "用户未登录"
  } else {
   if (err.response.data.message) {
    return err.response.data.message
   } else {
    return '请求数据失败,请稍后再试'
   }
  };
  // Do something with response error
 }
)
