headers 中添加了 cookie 但是请求头中始终没有携带

[hanxiaomin]

var site = new Site
{
CycleRetryTimes = 1,
SleepTime = 200,
Headers = new Dictionary<string, string>()
{
{ "Accept","/" },
{ "Referer", "https://ad.tt.com/login/"},
{ "Cookie","tt_webid=6582711285758166536" },
{ "Connection","keep-alive" },
{ "Content-Type","application/x-www-form-urlencoded" },
{ "User-Agent","Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36"}
}
};

默认的，HttpClientHandler的UseCookies为True，Cookie由CookieContainer维护，所以写到请求头的Cookie会被忽略，应该写入关联的CookieContainer；

非常抱歉，第一次用dotnetspider, 应该怎么去关联CookieContainer呢？
