在Vue中如何使用Cookie操作实例

# 全局安装 vue-cli
$ npm install --global vue-cli
# 创建一个基于 webpack 模板的新项目
$ vue init webpack my-project
# 安装依赖，走你
$ cd my-project
$ npm install

//获取cookie、
export function getCookie(name) {
 var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");
 if (arr = document.cookie.match(reg))
  return (arr[2]);
 else
  return null;
}

//设置cookie,增加到vue实例方便全局调用
export function setCookie (c_name, value, expiredays) {
 var exdate = new Date();
 exdate.setDate(exdate.getDate() + expiredays);
 document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString());
};

//删除cookie
export function delCookie (name) {
 var exp = new Date();
 exp.setTime(exp.getTime() - 1);
 var cval = getCookie(name);
 if (cval != null)
  document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();
};

import axios from 'axios' //引用axios
import {getCookie} from './util' //引用刚才我们创建的util.js文件，并使用getCookie方法

// axios 配置
axios.defaults.timeout = 5000; 
axios.defaults.baseURL = 'http://localhost/pjm-shield-api/public/v1/'; //这是调用数据接口

// http request 拦截器，通过这个，我们就可以把Cookie传到后台
axios.interceptors.request.use(
  config => {
    const token = getCookie('session'); //获取Cookie
    config.data = JSON.stringify(config.data);
    config.headers = {
      'Content-Type':'application/x-www-form-urlencoded' //设置跨域头部
    };
    if (token) {
      config.params = {'token': token} //后台接收的参数，后面我们将说明后台如何接收
    }
    return config;
  },
  err => {
    return Promise.reject(err);
  }
);


// http response 拦截器
axios.interceptors.response.use(
  response => {
//response.data.errCode是我接口返回的值，如果值为2，说明Cookie丢失，然后跳转到登录页，这里根据大家自己的情况来设定
    if(response.data.errCode == 2) {
      router.push({
        path: '/login',
        query: {redirect: router.currentRoute.fullPath} //从哪个页面跳转
      })
    }
    return response;
  },
  error => {
    return Promise.reject(error.response.data)
  });
