import axios from 'axios'
    import router from '@/router'
    
    axios.defaults.timeout = 3000
    axios.defaults.baseURL = ''
    
    axios.interceptors.request.use(
      config => {
        //  const token = getCookie('名称')
        config.data = config.data
        config.headers = {
          'Content-Type': 'application/json; charset=utf-8'
        }
        if (config.url === '/api/login/index') {
    
        } else {
          if (localStorage.getItem('Authorization')) {
            config.headers.Authorizatior = localStorage.getItem('Authorization')
          }
        }
        //  if (token) {
        //  config.params = {'token': token}
        //  }
        return config
      },
      error => {
        return Promise.reject(error)
      }
    )
    
    axios.interceptors.response.use(
      response => {
        //返回错误跳转到首页
        if (response.data.code === 0) {
          router.push({
            path: '/',
            querry: {
              redirect: router.currentRoute.fullPath
            }
          })
        }
        return response
      },
      error => {
        if (error.response) {
          switch (error.response.status) {
            case 401:
              localStorage.removeItem('Authorization')
              router.push('/login')
          }
        }
        return Promise.reject(error)
      }
    )
    
    /**
     * 封装get方法
     * @param url
     * @param data
     * @returns {Promise}
     */
    
    export function fetch (url, params = {}) {
      return new Promise((resolve, reject) => {
        axios.get(url, {
          params: params
        })
        .then(response => {
          resolve(response.data)
        })
        .catch(err => {
          reject(err)
        })
      })
    }
    
    /**
     * 封装post请求
     * @param url
     * @param data
     * @returns {Promise}
     */
    export function post (url, data = {}) {
      return new Promise((resolve, reject) => {
        axios.post(url, data)
        .then(response => {
          resolve(response.data)
        }, err => {
          reject(err)
        })
      })
    }
    
    /**
     * 封装patch请求
     * @param url
     * @param data
     * @returns {Promise}
     */
    
    export function patch (url, data = {}) {
      return new Promise((resolve, reject) => {
        axios.patch(url, data)
          .then(response => {
            resolve(response.data)
          }, err => {
            reject(err)
          })
      })
    }
    
    /**
     * 封装put请求
     * @param url
     * @param data
     * @returns {Promise}
     */
    export function put (url, data = {}) {
      return new Promise((resolve, reject) => {
        axios.put(url, data)
          .then(response => {
            resolve(response.data)
          }, err => {
            reject(err)
          })
      })
    }

main.js调用

import { fetch, post, patch, put } from '@/util/fetch'
    
    Vue.prototype.get = fetch
    Vue.prototype.post = post
    Vue.prototype.patch = patch
    Vue.prototype.put = put

视图页面使用

export default {
      name: 'login',
      data () {
        return {
          mobile: '',
          password: ''
        }
      },
      components: {
        XInput,
        XButton,
        Group,
        Box
      },
      methods: {
        handleLogin () {
          let params = {}
          params.username = this.mobile
          params.password = this.password
          this.post('/api/driver/index', params).then((data) => {
            console.log(data)
          }).catch((error) => {
           console.log(error)
          })
        }
      }
    }
