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cookieexport 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axiosimport {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)  });export default axios;/** * fetch 请求方法 * @param url * @param params * @returns {Promise} */export function fetch(url, params = {}) {  return new Promise((resolve, reject) => {    axios.get(url, {      params: params    })    .then(response => {      resolve(response.data);    })    .catch(err => {      reject(err)    })  })}/** * post 请求方法 * @param url * @param data * @returns {Promise} */export function post(url, data = {}) {  return new Promise((resolve, reject) => {    axios.post(url, data)      .then(response => {        resolve(response.data);      }, err => {        reject(err);      })  })}/** * patch 方法封装 * @param url * @param data * @returns {Promise} */export function patch(url, data = {}) {  return new Promise((resolve, reject) => {    axios.patch(url, data)      .then(response => {        resolve(response.data);      }, err => {        reject(err);      })  })}/** * put 方法封装 * @param url * @param data * @returns {Promise} */export function put(url, data = {}) {  return new Promise((resolve, reject) => {    axios.put(url, data)      .then(response => {        resolve(response.data);      }, err => {        reject(err);      })  })}
