在我的网站主页中频繁刷新推文而未达到速率限制答案

【问题标题】：Refresh tweets frequently in my site homepage without reaching to the rate limit在我的网站主页中频繁刷新推文而未达到速率限制
【发布时间】：2013-07-02 11:13:40
【问题描述】：

我正在开发需要向用户显示实时推文的网站。我使用 Tweet Sharp 库来获取推文。我的网站需要经常刷新推文，但有时我会收到 {"The remote server returned an error: (429) Too Many Requests."} 错误。由于我的网站需要实时信息，我必须经常获取推文。我怎样才能做到这一点？如何在不达到速率限制的情况下获取最新推文？

 TwitterService service=new TwitterService(AppSetting.objTwitterClientInfo.ConsumerKey, AppSetting.objTwitterClientInfo.ConsumerSecret, AppSetting.objTwitterModerateInfo.ModerateAccessToken, AppSetting.objTwitterModerateInfo.ModerateAccessTokenSecret);

        var options = new ListTweetsOnHomeTimelineOptions();
        options.ExcludeReplies = false;
        options.Count = intTotalRec;
        var lstTwitterStatus = service.ListTweetsOnHomeTimeline(options);

【问题讨论】：

为什么不直接使用他们提供的 twitter 小部件？ twitter.com/settings/widgets
经过一番谷歌搜索后我的猜测是这样的； dev.twitter.com/docs/streaming-apis
我不能使用 Twitter 小部件，我的要求不同。我正在与股票相关的网站上工作。它需要来自多个 Twitter 帐户的数据。
@dutt ：是的，我看到了 Twitter 建议的有关 Streaming API 的文档。但我不知道如何实现它，因为我是 Twitter 新手。

你可以像这样使用流式API：-

public void Can_stream_from_user_stream() {
            const int maxStreamEvents = 5;

            var block = new AutoResetEvent(false);
            var count = 0;


            service.StreamUser((streamEvent, response) =>
            {
                if (streamEvent is TwitterUserStreamEnd)
                {
                    block.Set();
                }

                if (response.StatusCode == 0)
                {
                    if (streamEvent is TwitterUserStreamFriends)
                    {
                        var friends = (TwitterUserStreamFriends)streamEvent;
                        Assert.IsNotNull(friends);
                        Assert.IsNotNull(friends.RawSource);
                        Assert.IsTrue(friends.Ids.Any());
                    }

                    if (streamEvent is TwitterUserStreamEvent)
                    {
                        var @event = (TwitterUserStreamEvent)streamEvent;
                        Assert.IsNotNull(@event);
                        Assert.IsNotNull(@event.TargetObject);
                        Assert.IsNotNull(@event.RawSource);
                        Console.Write(@event.Event + "\n" + @event.Source + "\n" + @event.Target);
                    }

                    if (streamEvent is TwitterUserStreamStatus)
                    {
                        var tweet = ((TwitterUserStreamStatus)streamEvent).Status;
                        Assert.IsNotNull(tweet);
                        Assert.IsNotNull(tweet.Id);
                        Assert.IsNotNull(tweet.User);
                        Assert.IsNotNull(tweet.RawSource);
                        Assert.IsNotNull(tweet.User.ScreenName);
                        Console.WriteLine(tweet.User.ScreenName + "\n" + tweet.Text);
                    }

                    if (streamEvent is TwitterUserStreamDirectMessage)
                    {
                        var dm = ((TwitterUserStreamDirectMessage)streamEvent).DirectMessage;
                        Assert.IsNotNull(dm);
                        Assert.IsNotNull(dm.Id);
                        Assert.IsNotNull(dm.Sender);
                        Assert.IsNotNull(dm.Recipient);
                        Assert.IsNotNull(dm.RawSource);
                        Console.WriteLine(dm.SenderScreenName + "\n" + dm.RecipientScreenName + "\n" + dm.Text);
                    }

                    if (streamEvent is TwitterUserStreamDeleteStatus)
                    {
                        var deleted = (TwitterUserStreamDeleteStatus)streamEvent;
                        Assert.IsNotNull(deleted);
                        Assert.IsTrue(deleted.StatusId > 0);
                        Assert.IsTrue(deleted.UserId > 0);
                    }

                    if (streamEvent is TwitterUserStreamDeleteDirectMessage)
                    {
                        var deleted = (TwitterUserStreamDeleteDirectMessage)streamEvent;
                        Assert.IsNotNull(deleted);
                        Assert.IsTrue(deleted.DirectMessageId > 0);
                        Assert.IsTrue(deleted.UserId > 0);
                    }

                    count++;
                    if (count == maxStreamEvents)
                    {
                        block.Set();
                    }
                }
                else
                {
                    Assert.Ignore("Stream responsed with status code: {0}", response.StatusCode);
                }
            });

            block.WaitOne();
            service.CancelStreaming();
        }
