Vue-resource拦截器判断token失效跳转

在拦截器中设置全局的token判断，意味着每次http请求都会校验token，与后台约定好的token过期返回码可以自定义跳转路径；

var token = window.localStorage.getItem("token");Vue.http.interceptors.push(function(request, next) {    request.headers.set('token', token); //setting request.headers    next(function(response){        if(response.body.code===401){ //与后台约定登录失效的返回码            parent.location.href ='/login.html';        }        return response    })})
