Question

我有这个代码试图通过Yahoo!进行身份验证它在我的本地服务器上工作正常，但在我的实时服务器上发出的相同请求失败。当它调用GetResponse()时，它会返回（401）Unauthorized错误。谁能帮我理解为什么？如果您需要更多信息，请与我们联系。

try
{
    string url = "https://api.login.yahoo.com/oauth/v2/get_request_token?oauth_callback=" + Server.UrlEncode("http://www.dowdlefolkart.com/extensions/contacts/webform1.aspx");
    url = GetUrl(url, consumerKey, consumerSecret);

    var req = System.Net.HttpWebRequest.Create(url);
    using (var res = req.GetResponse().GetResponseStream())
    {
        ....
    }
}
catch (Exception ex)
{
    Response.Write("ERROR" + ex.Message);
}

以下是完整的错误异常：

更新

我收到了Fiddler的错误。

oauth_problem=timestamp_refused&oauth_acceptable_timestamps=1314119105-1314120305

所以看起来我的实时服务器的时间戳不正确。这就是我创建时间戳的方式：

string timestamp = Math.Floor((DateTime.UtcNow - new DateTime(1970, 1, 1)).TotalSeconds).ToString();

Answer 1

我发现了这个问题。出错的原因是时间戳无效。它比允许的略大。使用Fiddler我能够确定这个问题。错误是：oauth_problem=timestamp_refused&oauth_acceptable_timestamps=1314119105-1314120305。

然后我登录到我的实时服务器并将系统时钟调整到需要的状态。显然快了15分钟。一旦我调整了这个错误就消失了。谢谢@Darin Dimitrov的帮助。

雅虎，OAuth http请求。适用于localhost但不适用于实时服务器
