HttpWebRequest 添加 cookie 异常

Question

我正在尝试使用 cookie 创建 HttpWebRequest：

        HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://myweb.com/get_my_web/");
        req.Method = "POST";

        if (req.CookieContainer == null)
        {
            req.CookieContainer = new CookieContainer();
        }

        System.Net.Cookie newCookie = new System.Net.Cookie("sessionid", AppData.sessionid,
                        "\\", "myweb.com");
        req.CookieContainer.Add(newCookie);

在req.CookieContainer.Add(newCookie); 我得到这个异常：

An unhandled exception of type 'System.Net.CookieException' occurred in System.dll

Additional information: The 'Domain'='myweb.com' part of the cookie is invalid.

知道这里有什么问题吗？

错误消息具有误导性 - 问题出在 cookie 路径而不是域中。 "\\" 是无效路径，我想你的意思是/：

System.Net.Cookie newCookie = new System.Net.Cookie("sessionid", AppData.sessionid,
    "/", "myweb.com");
