我正在按照本教程讲解如何授权和从Web-api服务器获取承载令牌。通过fiddler在那里执行的任务非常简单，但是，当我尝试从控制台应用程序执行相同操作时，请求失败，并显示400 Bad Request Error。这是向服务器发出请求的代码：

var request = WebRequest.Create("http://localhost:12698/token") as HttpWebRequest;
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    request.CookieContainer = new CookieContainer();         
    var authCredentials = "userName=" + user + "&password=" + password;
    byte[] bytes = System.Text.Encoding.UTF8.GetBytes(authCredentials);
    request.ContentLength = bytes.Length;
    using (var requestStream = request.GetRequestStream()){
        requestStream.Write(bytes, 0, bytes.Length);
    }

    using (var response = request.GetResponse() as HttpWebResponse){
        authCookie = response.Cookies["access_token"];
    }

有人可以帮助我确定我在做什么错吗？还是我应该使用其他方法来获取身份验证令牌？
