Vue如何为GET或POST请求设置请求头

npm install vue-cookies --save

import Vue from 'vue'
import VueCookies from 'vue-cookies'
Vue.use(VueCookies);

this.$cookies.set("自定义名字",后台获取的token)

 //Login.vue
 Login(){   //登录
           this.$http.post('home/login',                            {"uPwd":this.password,"uPhone":this.account}).then(result=>{
                        if(result.body.status===200){
                            this.$cookies.set("auth",result.body.data);
                            let redirect=decodeURIComponent(this.$route.query.redirect||"/home");
                            this.$router.push({path:redirect});
                        }else{
              Toast('输入密码或账号错误，请重新输入');
                        }
                     }).catch(function(){
              console.log("服务器异常");
                     })
                }
         }

//index.js
Vue.http.interceptors.push((request, next) => {
    //请求发送前的处理逻辑
    request.headers.set('auth', VueCookies.get("auth"))
    next((response) => {
        //请求发送后的处理逻辑
        //根据请求的状态，response参数返回给successCallback或errorCallback
        return response
    })
})

//设置请求消息头
