如何在 nodejs socket.io 中创建 cookie

Question

im trying to create a cookie while using socket.io. I am able to read cookies but cannot find any information on how to create one.

 socket.on('test', async function(){
    
    //  view set cookies (works!)
    console.log('cookies', socket.handshake.headers.cookie);

    // create cookie here...
});

thank you

Answer 1

您可以像在 mdn 文档中使用 setcookies() 那样设置 cookie 并使用 cookie api 读取它

Answer 2

You can do it the same way as document.cookie , but instead of:

document.cookie = ";mycookie=myval";

you do:

socket.handshake.headers.cookie = ";mycookie=myval; expires=cookieDate; path=cookiePathOnWebsite"

for example:

var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = date.toGMTString();
socket.on('test',async function(){
  socket.handshake.headers.cookie = ";foo=bar; expires="+date+";path=/"
});

would set a cookie at the main page of your website, with foo defined as bar !
