通过vue如何设置header

this.$http
        .post(netUrl, change, {
          headers: {
            Authorization: "Bearer " + this.$cookies.get("token")
          }
        })
        .then(
          response => {
            console.log(response.data);
            if (response.data != null) {
            }
          },
          response => {
            console.log("error");
          }
        );

 headers: {
    Authorization: "Bearer " + this.$cookies.get("token")
  }

Vue.http.interceptors.push((request, next) => {
      // ...
      // 请求发送前的处理逻辑
     request.beforeSend = function() {
             request.headers['token'] = “token”;
     }
  next((response) => {
      // ...
      // 请求发送后的处理逻辑
      // ...
      // 根据请求的状态，response参数会返回给successCallback或errorCallback
      return response
  })

request.headers.set('token', "Bearer ")

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

import Vue from 'vue'
import VueCookies from 'vue-cookies'
Vue.use(VueCookies);
Vue.http.interceptors.push((request, next) => {
  // 请求发送前的处理逻辑
  request.headers.set('Authorization', "Bearer " + VueCookies.get("token"))
  next((response) => {
    // 请求发送后的处理逻辑
    // 根据请求的状态，response参数会返回给successCallback或errorCallback
    return response
  })
})
