vue.js axios使用

1. 自定义配置

/**

 * http配置
 */

import axios from ‘axios‘
import utils from ‘@/config/cookieUtils‘

// axios 配置
axios.defaults.baseURL = store.state.gateway_url

axios.defaults.headers.post[‘Content-Type‘] = ‘application/json‘

// http request 拦截器
axios.interceptors.request.use(
  config => {
      config.headers[‘Access-Token‘] = ‘xxxxxxxxxxx‘
    return config
  },
  err => {
    return Promise.reject(err)
})

// http response 拦截器
axios.interceptors.response.use(
  response => {
    var serverResult = response.data.serverResult
    if (serverResult && serverResult.resultCode !== ‘200‘ && serverResult.resultCode !== ‘10007‘ && serverResult.resultCode !== ‘10008‘ && serverResult.resultCode !== ‘10010‘) {
      var msg = serverResult.resultMessage
      console.log(‘msg = ‘ + msg)
      return Promise.reject(response)
    }
    return response
  },
  error => {
    // console.log(JSON.stringify(error));//console : Error: Request failed with status code 402
    if (error.response && error.response.data) {
      var errorJson = error.response.data
      if (errorJson.resultCode && errorJson.resultCode === 4210) {
        ElementUI.Message(
          {
            type: ‘error‘,
            message: ‘您的账号是退出状态，请重新登录！‘,
            onClose: function () {
              location.reload()
            }
          })
        return
      }
    }
    return Promise.reject(error.response.data)
})

export default axios

2.引入配置

import axios from ‘@/config/http‘

Vue.prototype.axios = axios

/* eslint-disable no-new */
const starter = new Vue({
  el: ‘#app‘,
  i18n,
  router,
  store,
  axios,
  lodash,
  render: h => h(App)
})
