How to delete cookies in vuejs?
vue.js sets, gets and deletes cookies
The project needs the front-end to obtain the cookies returned by the background and make judgments based on them. I used it under the main.js entry file
Specific code:
new Vue({ el: '#app', router, template: '<App/>', components: { App }, methods:{ //读取cookie,需要注意的是cookie是不能存中文的,如果需要存中文,解决方法是后端先进行编码encode(),前端取出来之后用decodeURI('string')解码。(安卓可以取中文cookie,IOS不行) getCookie(name) { var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)"); if (arr = document.cookie.match(reg)){ return true; // return (arr[2]); }else{ return false } }, //设置cookie name为cookie的名字,value是值,expiredays为过期时间(天数) setCookie (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 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(); } }, created(){ this.setCookie('openId',123,2) if (this.getCookie('openId')) { console.log('has cookie') this.delCookie ('openId') }else{ console.log('has not cookie') } } })
