为什么进行重定向时未设置cookie? [英] Why are the cookies not being set when doing a Redirect?

问题描述

或者也许我做错了，为什么在进行重定向时未设置cookie?

Or maybe i am doing it wrong, why are the cookies not being set when doing a Redirect?

static void doLogin()
{
    var req = HttpContext.Current.Request;
    ...
    user_cookie.set(userId, loginId);
    ...
    HttpContext.Current.Response.Redirect(req["returnLocation"]);
}

static public void set(long userId, long loginId)
{
    var cookies = HttpContext.Current.Request.Cookies;
    var u = new HttpCookie("userId", userId.ToString());
    u.HttpOnly = true;
    var l = new HttpCookie("loginId", loginId.ToString());
    l.HttpOnly = true;
    cookies.Add(u);
    cookies.Add(l);
}

推荐答案

您正在将cookie添加到请求.Cookies集合，您希望将其添加到响应.改为收集Cookie.

You're adding cookies to the Request.Cookies collection, you'll want to add them to the Response.Cookies collection instead.

还要注意，Response.Redirect将中止我所见过的当前线程，这有时会导致问题.Response.Redirect(url，false)将重定向而不会中止.

Also note that Response.Redirect will abort the current thread which I've seen cause problems on occasion. Response.Redirect( url, false ) will redirect without aborting.
