c# - Twitterizer 底层连接已关闭

Question

我使用 twitterizer 发推文和关注，但是在文件 TwitterCommand.cs 中，在线

responseData = ConversionUtility.ReadStream(exceptionResponse.GetResponseStream());

我得到一个异常:底层连接已关闭:服务器关闭了预期保持事件状态的连接。

exceptionResponse 为 null，所以上面的代码看起来像抛出异常:

// The exception response should always be an HttpWebResponse, but we check for good measure.
HttpWebResponse exceptionResponse = wex.Response as HttpWebResponse;

if (exceptionResponse == null)
{
    throw;
}

不明白为什么会这样=\

Uri，在代码中:http://api.twitter.com/1/statuses/update.json ，因此，更新状态(推文)时会出现异常。

我使用这段代码进行更新:

TwitterStatusAsync.Update(token, tweet, null, TimeSpan.FromSeconds(0), (resp) =>
        {
            TwitterAsyncResponse<TwitterStatus> response = resp;
            if (response.Result != RequestResult.Success)
            {
                this._twtLogger.addLine(String.Format("{0}: error when get response from server", account.title));
                this._twtLogger.addLine(String.Format("{0}: {1}", account.title, response.ErrorMessage));
                return;
            }

            this._twtLogger.addLine(String.Format("{0}> {1}: Tweeted ok!", response.ResponseObject.CreatedDate, account.title));
        });

添加:

这似乎是连接问题。检查您的代理/防火墙设置。另外，尝试同步调用，看看它是否有效。 (我怀疑它不会，但它可能会帮助您调试问题。)
