vue axios 的封装

//http.js


import Vue from 'vue'
import axios from "axios"



const Axios = axios.create({
  timeout: 30000,
  //responseType:"json",
  withCredentials:false,
});


/**
  axios访问前的拦截，增加配置信息
  baseURL=反向代理的URL地址，配置在nginx、apache下有效,tomcat下请配置为/
  data=将json转换为字符发送
  headers = 设置HTTP头文件，其中token是登陆时从服务器获取的
  withCredentials = 提交时是否携带cookie
*/

  config => {

    var token = sessionStorage.getItem("account.token") || "";
    if (token && token != "") {
      config.headers = {
        "Authorization": 'Bearer ' + token,

/**
 * 封装get方法

 * @returns {Promise}
 */

const get = function (url, param = {}) {
  return new Promise((resolve, reject) => {
    Axios.get(url, {
        params: JSON.stringify(param),
      })
      .then(response => {
        resolve(response.data);
      })
      .catch(err => {
        resolve({
          code: "no",
          msg: err.err
        });
        //reject(err)
      })
  }) 
}

const post = function (url, param = {}, bURL=Vue.prototype.config.proxy) {
  let config = {
    baseURL:bURL
  }
  return new Promise((resolve, reject) => {    
    Axios.post(url, param, config).then(response => {
        resolve(response.data);

    }).catch(err => { 
      var t = err.err.response.data
      resolve(t);
    })
  })
}

export default {
  install: function (Vue, Option) {
    Object.defineProperty(Vue.prototype, "$http", {
      value: Axios
    });
    Object.defineProperty(Vue.prototype, "$get", {
      value: get
    });
    Object.defineProperty(Vue.prototype, "$post", {
      value: post
    });
  }
};

然后在main.js中引入：
import axios from '@/assets/js/http.js'
Vue.use(axios);

在项目中使用：
this.$post(this.api.organize.list, p).then((res) => {});
