Twitterizer 底层连接已关闭答案

【问题标题】：Twitterizer the underlying connection was closedTwitterizer 底层连接已关闭

【问题描述】：

我使用 twitterizer 进行推文和关注，但在文件 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活动状态的连接。

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，代码为：http://api.twitter.com/1/statuses/update.json，所以在更新状态（推文）时会出现异常。

为了更新我使用这个代码：

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：

【问题讨论】：

你能发布异常的堆栈跟踪吗？

【解决方案1】：

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。）

【讨论】：

这发生在 30 分钟或 1 小时的漂亮推文之后。 =\
无法理解如何解决这个问题 :( 同步也出现异常崩溃。
