Answer 1

您可以使用 HttpWebRequest 执行此操作:

public static string GetRedirectedUrls(string url)
{
    StringBuilder sb = new StringBuilder();
    while (!string.IsNullOrWhiteSpace(url))
    {
        sb.AppendLine(url);
        HttpWebRequest request = HttpWebRequest.CreateHttp(url);
        request.AllowAutoRedirect = false;
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        {
            url = response.GetResponseHeader("Location");
        }
    }

    return sb.ToString();
}
