vue使用axios多环境多api配置

封装axios的js方法

import axios from 'axios'
import {
  MessageBox,
  Message
} from 'element-ui'
import store from '@/store'
import {
  getToken
} from '@/utils/auth'

// create an axios instance
const service = axios.create({
  baseURL: process.env.VUE_APP_BASE_API,
  timeout: 20000 // request timeout
})

// request interceptor
service.interceptors.request.use(
  config => {
    // do something before request is sent

    // 统一设置请求消息头token
    const mytoken = {
      client: 'backstage',
      token: getToken()
    }
    if (store.getters.token) {
      config.headers['x-access-token'] = JSON.stringify(mytoken)
    }
    return config
  },
  error => {
    // do something with request error
    console.log(error) // for debug
    return Promise.reject(error)
  }
)

// response interceptor
service.interceptors.response.use(
  /**
   * If you want to get http information such as headers or status
   * Please return  response => response
   */
  response => {
    const res = response.data
    if (res.code !== 0) {
      Message({
        message: res.message || 'Error',
        type: 'error',
        duration: 5 * 1000
      })

      if (res.code === 2001) {
        // to re-login
        MessageBox.confirm('登录超时，请重新登录', '提示', {
          confirmButtonText: '重新登录',
          cancelButtonText: '取消',
          type: 'warning'
        }).then(() => {
          store.dispatch('user/resetToken').then(() => {
            location.reload()
          })
        })
      }
      return Promise.reject(new Error(res.message || 'Error'))
    } else {
      return res
    }
  },
  // 相应失败的处理
  error => {
    console.log('err' + error) // for debug
    Message({
      message: error.message,
      type: 'error',
      duration: 4 * 1000
    })
    return Promise.reject(error)
  }
)

export default service

使用axios方法封装api

import request from '@/utils/request' // 引入封装的请求方法

export function allShopList(data) {
  return request({
    url: '/allStore/shopList',
    method: 'post',
    data,
    baseURL: process.env.VUE_APP_PEISONG_API // url = base url + request url 重写基础地址
  })
}

配置环境变变量

新建 .env.development .env.production .env.staging 文件编写环境变量如

NODE_ENV = production

# just a flag
ENV = 'staging'

# base url
VUE_APP_URL = 'xxxxxx'

# base api
VUE_APP_BASE_API = 'xxxxx'

# peisong api
VUE_APP_PEISONG_API = 'xxxxx'

每个文件写对应地址就可以了 修改package.json文件配置,就可以用对应指令区分打包测试或者成产环境

'scripts': {
     "dev": "vue-cli-service serve",
    "build:prod": "vue-cli-service build",
    "build:stage": "vue-cli-service build --mode staging",
}

Api的使用

在对应vue文件引入需要的api方法，传入需要的参数用promise处理就好了
