2.返回拦截
fly.interceptors.response.use(

if (response.data.code === 1001) {
mpvue.navigateTo({url: ‘../accredit/main‘}) // 返回提示需要登陆需要跳转授权登陆页 或者弹窗 授权只能通过按钮触发
}
if (response.data.code === 1002) {
fly.lock() //token过期 锁住拦截器
return store.dispatch(‘accreditLogin‘).then(res => { // 使用新起的拦截器发送登陆接口
}).finally(() => fly.unlock()).then(() => {
return fly.request(response.request) // 返回上一个请求
})
}
return promise.resolve(obj)
}
}
