1,下載
npm install axios -S
2, qs不用引入
需要引入vant 的彈出框 因?yàn)橄旅嬗玫?/p>

http.js文件

import axios from "axios";
import { Toast } from "vant";
import QS from 'qs';
// import router from '../router';
// 環(huán)境的切換
// if (process.env.NODE_ENV == 'development') {    
//     axios.defaults.baseURL = 'https://www.baidu.com';} 
// else if (process.env.NODE_ENV == 'debug') {    
//     axios.defaults.baseURL = 'https://www.ceshi.com';
// } 
// else if (process.env.NODE_ENV == 'production') {    
//     axios.defaults.baseURL = 'https://www.production.com';
// }
let localhosts = "http://www.oa.com/v1.0"; //請求的后臺(tái)域名
axios.interceptors.request.use(
  config => {
    //請求之前(可以設(shè)置token)
    // if (localStorage.getItem('token')){  // 判斷是否存在token命满，如果存在的話堪夭，則每個(gè)http header都加上token
    config.headers.common['Token'] = localStorage.getItem('tokenMobile') || ''
    // }
    return config;
  },
  error => {
    Toast(error);
    return Promise.reject(error);
  }
);
axios.interceptors.response.use(
  response => {
    //數(shù)據(jù)拿到之后
    return response.data;
  },
  error => {
    Toast("Http請求失敗须肆，請聯(lián)系管理員");
    return Promise.reject(error.response);
  }
);
function successfun(res) {
  //處理后臺(tái)返回的非200錯(cuò)誤
  if (res.code === 0) {
    return res;
  } else {
    Toast(res.message);
    return res;
  }
}
function errorfun(res) {
  if (res.code != 0) {
    Toast(res.message);
    return res;
  }
}
export default {
  post(url, data) {
    //post請求
    return axios({
      method: "post",
      baseURL: localhosts,
      url,
      data: QS.stringify(data),
    }).then(
      res => {
        return successfun(res);
      },
      err => {
        return errorfun(err);
      }
    );
  },
  get(url, params) {
    //get請求
    return axios({
      method: "get",
      baseURL: localhosts,
      url,
      params,
    }).then(
      res => {
        return successfun(res);
      },
      err => {
        return errorfun(err);
      }
    );
  }
};

api.js文件

export default {
  enterprise_wechat_menus: "/enterprise_wechat/menus",
  flow_dev_common: "/flow/dev_common" 
};

其他頁面調(diào)用

created(){

   this.http.post(this.api.enterprise_wechat_menus)
   .then(res => {
        this.content = res.data
    });
            
 },

作為參考的路由文件router/index.js 腳手架的目錄和文件,里面加了攔截器和保存token
