在asp.net中集成Google Analytic时出现404错误请求错误

Question

我在asp.net中集成了Google Analytic，这给了我错误的404错误请求。我正在使用google anayltics v3，其中https://www.google.com/analytics/feeds/data是绝对的。这就是为什么我使用https://www.googleapis.com/analytics/v2.4/data而是再次404这一行出错

string result = webClient.DownloadString（feedUrl）; 当我删除代码时 feedUrl = https://www.google.com/analytics/feeds/data?ids=ga:UA-55271282-1&dimensions=ga:pagePath&metrics=ga:pageviews&sort=-ga:pageviews&start-date=2011-06-25&end-date=2011-07-25“

任何帮助将不胜感激。
