nodejs获取cookie

//cookie之后转换为对象

req.cookie={};

const cookieStr=req.headers.cookie;

cookieStr.split(';').forEach(item=>{

if(!item)

{

return

}

const arr=item.split('=')

const key=arr[0]

const val =arr[1]

req.coolie[key]=val

})

 

服务器端操作cookie

res.setHeader('Set-Cookie','username=${data.username};path=/;httponly')//httponly只允许后端修改，不允许前端修改

设置cookie过期时间

const getCookieExpires=()=>{

const d=new Date()

d.setTime(d.getTiem()+(24*60*60*1000))//当前时间加一天

return d.toGMTString()

}

之后在上面httponly后面加上expires=${getCookieExpires()}
