从服务器端以编程方式发送 Google Analytics 事件不起作用

Question

我们想从服务器端向谷歌分析发送自定义事件跟踪信息。为此，我参考了这篇SO post，并提出了以下代码片段，但不知何故它没有将事件的信息发送到 GA。我调试了代码以查看响应，它返回200 (OK)状态，响应类似于通过客户端跟踪事件时的响应。我们已经等了几天，看看事件是否被跟踪，但它没有。    public static void TrackEvent(string category, string action, string label)    {        string gaCodeTest = "UA-xxxxxx-2";        ASCIIEncoding encoding = new ASCIIEncoding();        string cid = Guid.NewGuid().ToString();        string postData =            "v=1&tid=" + gaCodeTest + " &cid=" + cid + "&t=event" +            "&ec=" + category +            "&ea=" + action +            "&el=" + label;        byte[] data = encoding.GetBytes(postData);        HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("https://www.google-analytics.com/collect");        myRequest.Method = "POST";        myRequest.ContentType = "application/x-www-form-urlencoded";        myRequest.ContentLength = data.Length;        Stream newStream = myRequest.GetRequestStream();        newStream.Write(data, 0, data.Length);        var response = (HttpWebResponse)myRequest.GetResponse();        //var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();        newStream.Close();    }
