Question

我有来自两台不同机器的两个浏览器进入测试页面。测试页面正在检索cookie。如果没有，它会创建一个cookie。

public string GetUserCookieId()
{
    string cookieName = "CookieId3";

    HttpCookie userInfoCookies = Request.Cookies[cookieName];

    string cookieId = "";

    if (userInfoCookies != null)
        cookieId = userInfoCookies.Value;

    if (string.IsNullOrEmpty(cookieId))
    {
        cookieId = Guid.NewGuid().ToString();

        HttpCookie cookie = new HttpCookie(cookieName);
        cookie.Value = cookieId;
        cookie.Expires = DateTime.Now.AddDays(90);
        Response.SetCookie(cookie);
    }

    return cookieId;
}

两台浏览器计算机都在页面上显示相同的Cookie值。这甚至一旦我将cookie重命名为“CookieId3”。请告诉我我哪里出错了。

如您所见，该方法不是静态的。谢谢

当从ClassLibrary访问代码时，问题似乎是Request和HttpContext.Current.Request之间的区别。

有人能够对此有所了解吗？！

以下作品。

public string GetUserCookieId()
{
    string cookieName = "CookieId18";

    HttpCookie userInfoCookies = HttpContext.Current.Request.Cookies[cookieName];

    string cookieId = "";

    if (userInfoCookies != null)
        cookieId = userInfoCookies.Value;

    if (string.IsNullOrEmpty(cookieId))
    {
        cookieId = Guid.NewGuid().ToString();

        HttpCookie cookie = new HttpCookie(cookieName);
        cookie.Value = cookieId;
        cookie.Expires = DateTime.Now.AddDays(90);
        HttpContext.Current.Response.SetCookie(cookie);
    }

    return cookieId;
}

Cookie与两个不同的浏览器计算机客户端相同
