我们有一个由多个页面组成的 Web 应用程序。我们将我们的 Web 应用程序域注册到 Google Analytics，并且页面浏览量跟踪按预期工作（在 Analytics 面板中，我们可以看到每个页面的页面浏览量）。现在我们希望将此页面查看信息存储在我们数据库的后端。所以我们想创建一个每天运行一次的后端进程，并从 Analytics API 中获取页面浏览量。

这当然需要在代码中完成。从初步研究看来，为了访问 Analytics API，必须进行身份验证过程，这意味着人类用户必须输入 ID 和密码。

问题是，只能用代码完成吗？

    //-------------- Get Auth Token -------------------

    WebClient webClient = new WebClient();
    NameValueCollection data = new NameValueCollection();
    data.Add("accountType", "GOOGLE");
    data.Add("Email", "xxxx@gmail.com");
    data.Add("Passwd", "xxxx");//Passwd, not a misspell.
    data.Add("service", "analytics");
    data.Add("source", "xxxx-xxxx-xx");//Could be anything.

    byte[] bytes = webClient.UploadValues("https://www.google.com/accounts/ClientLogin", "POST", data);
    string tokens = Encoding.UTF8.GetString(bytes);
    string authToken = extractAuthToken(tokens);

    //-------------- Get page views -------------------

    string feed = "https://www.google.com/analytics/feeds/data";

    //Required:
    string ids = "ga:xxxx";
    string metrics = "ga:pageviews";
    string startDate = "2011-06-25";
    string endDate = "2011-07-25";

    //Optional:
    string dimensions = "ga:pagePath";
    string sort = "-ga:pageviews";            

    string feedUrl = string.Format("{0}?ids={1}&dimensions={2}&metrics={3}&sort={4}&start-date={5}&end-date={6}",
        feed, ids, dimensions, metrics, sort, startDate, endDate);

    webClient.Headers.Add("Authorization", "GoogleLogin " + authToken);
    string result = webClient.DownloadString(feedUrl);

    //-------------- Extract data from xml -------------------

    XDocument xml = XDocument.Parse(result);
    var ns1 = "{http://www.w3.org/2005/Atom}";
    var ns2 = "{http://schemas.google.com/analytics/2009}";

    var q = from entry in xml.Descendants()
            where entry.Name == ns1 + "entry"
            select new
            {
                PagePath = entry.Element(ns2 + "dimension").Attribute("value").Value,
                Views = entry.Element(ns2 + "metric").Attribute("value").Value
            };

    //-------------- Do something with data -------------------
    foreach (var page in q)
    {
        Debug.WriteLine(page.PagePath + " " + page.Views);                
    }

    //-------------- Help Method -------------------
    private string extractAuthToken(string data)
    {          
        var tokens = data.Split(new string[] { "\n" }, StringSplitOptions.RemoveEmptyEntries);            
        return tokens.Where(token => token.StartsWith("Auth=")).Single();
    }
