安装

利用npm安装npm install axios --save

封装

request.js：

import axios from 'axios'
import { Message } from 'element-ui'
import store from '../vuex/index'

/* eslint-disable new-cap */
const service = new axios.create({
  timeout: 20000
})

service.interceptors.request.use(
  config => {
    if (config.url.indexOf('token=') === -1) {
      // 把token参数拼接在url后
      config.url = `${config.url}?token=${window.sessionStorage.token.replace(/"/g, '')}`
    }
    return config
  },
  error => {
    window.console.log(error)
    Promise.reject(error)
  }
)

service.interceptors.response.use(
  response => {
    if (
      response.request.responseType === 'blob' // 文件上传，返回文件流
    ) {
      return response
    }
    const res = response.data
    if (res.baseRes) {
      res.code = res.baseRes.code
      res.desc = res.baseRes.desc
    }
    if (res.code !== 100) {
      store.commit('updateLoading', false)
      Message({
        message: res.desc,
        type: 'error',
        duration: 3 * 1000
      })
      if (res.code === 919 || res.code === 918) {
        // 登陆过期。
        setTimeout(() => {
          Message({
            message: response.data.baseRes.desc,
            type: 'error'
          })
          // 跳转到登陆页面
          window.location.href = 'xxx'
        }, 3000)
      } else {
        return response.data
      }
    } else {
      return response.data
    }
  },
  error => {
    store.commit('updateLoading', false)
    Message({
      message: error.message,
      type: 'error',
      duration: 3 * 1000
    })
    return Promise.reject(error)
  }
)

export default service

api/common/index.js：

import request from '@/utils/request'

export function getSystemMenu (params) {
  return request({
    method: 'get',
    url: `${window.msBaseUrl}services/systemMenu.json`,
    params
  })
}

export function getMallCategoryList (params) {
  return request({
    url: `${window.msNewBaseUrl}config/list`,
    method: 'post',
    data: params
  })
}

页面使用：

import { getSystemMenu } from '@/api/common/index'
const params = {
    skuId: this.formData.skuId,
    platForm: 1
}
queryProdSkuId(params)
      .then(
        res => {
          if (res.baseRes.code == 100) {
            let data = res.baseRes.result          
          } else {
            this.formData.skuId = null
          }
        },
        err => {
        }
)
      .catch(err => {
})
