我们有一个由几个页面组成的Web应用程序.我们已将我们的网络应用域注册到Google Analytics,并且网页浏览量跟踪按预期工作(在Google Analytics面板中,我们可以看到每个网页的网页浏览量).现在我们希望此页面视图信息存储在我们的DB内部的后端.因此,我们希望创建一个每天运行一次的后端流程,并从Analytics API中获取页面视图.
这当然需要在代码中完成.从最初的研究看来,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,它只能用代码完成吗？
解决方法
//-------------- 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();
}
