1.手动获取

手动查看cookie，找到B站cookie的 SESSDATA, DedeUserID, bili_jct

2.js/jq获取

在B站的页面使用，输出B站cookie的DedeUserID和bili_jct

SESSDATA为HttpOnly，js不能获取。

'use strict'

var cookie_arr = document.cookie.split(';');

for(var i = 0; i < cookie_arr.length; i++) {
    var ckname = cookie_arr[i].split('=')[0];
    var ckcont = cookie_arr[i].split('=')[1];
    if(ckname == ' DedeUserID') {
        console.log('DedeUserID: ' + ckcont);
    }
    else if(ckname == ' bili_jct') {
        console.log('bili_jct: ' + ckcont);
    }
}

3.python获取

适用于Edge浏览器

登录后关闭浏览器使用
