我正在尝试使用本地控制台应用程序从Google Analytics(分析)中检索数据。我无需提取到Google帐户即可提取某些数据,而仅使用API。
问题是我没有获得正确的值,而且我不确定如何格式化代码以提取正确的值。我不会在特定时间范围内检索所有访客,在这种情况下,本例中为“ 2012-01-01”-“ 2014-02-20”。在Google Analytics(分析)信息中心中查看时,实际访问者人数大约是其10倍。调试代码时,我得到的数字是15000。我在控制台中显示d.TotalResults可能是错误的,变量“ d”包含许多不同的属性。
这是我正在运行的代码:
public static void Main(string[] args)
{
var serviceAccountEmail = "MY@developer.gserviceaccount.com";
var certificate = new X509Certificate2(@"C:\Users\User\Desktop\key.p12", "notasecret", X509KeyStorageFlags.Exportable);
var credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = new[] { AnalyticsService.Scope.Analytics }
}.FromCertificate(certificate));
// Create the service.
//Twistandtango
var gas = new AnalyticsService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "TestGoogleAnalytics",
});
var r = gas.Data.Ga.Get("ga:MYProfileID", "2012-01-01", "2014-02-20", "ga:visitors");
//Specify some addition query parameters
r.Dimensions = "ga:pagePath";
r.Sort = "-ga:visitors";
r.MaxResults = 5;
//Execute and fetch the results of our query
Google.Apis.Analytics.v3.Data.GaData d = r.Execute();
Console.WriteLine(d.TotalResults);
Console.ReadLine();
}

我正在尝试使用此工具https://ga-dev-tools.appspot.com/explorer/查询我想要的结果。当我在代码中实现它时,它看起来像这样:
public static void Main(string[] args)
{
var serviceAccountEmail = "MY@developer.gserviceaccount.com";
var certificate = new X509Certificate2(@"C:\Users\User\Desktop\key.p12", "notasecret", X509KeyStorageFlags.Exportable);
var credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
Scopes = new[] { AnalyticsService.Scope.Analytics }
}.FromCertificate(certificate));
// Create the service.
//Twistandtango
var gas = new AnalyticsService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = "TestGoogleAnalytics",
});
var r = gas.Data.Ga.Get("ga:MYProfileID", "2012-01-01", "2014-02-20", "ga:visits");
//Specify some addition query parameters
r.Dimensions = "ga:visitCount";
r.Metrics = "ga:visits";
r.Segment = "gaid::-1";
//r.Sort = "-ga:visitors";
r.MaxResults = 10000;
//Execute and fetch the results of our query
Google.Apis.Analytics.v3.Data.GaData d = r.Execute();
Console.WriteLine(d.TotalResults);
Console.ReadLine();
}
}

但是,将度量(r.Metrics = "ga:visits";
)添加到项目后,出现以下错误:
错误7无法将属性或索引器“ Google.Apis.Analytics.v3.DataResource.GaResource.GetRequest.Metrics”分配给它-只读
另外,这是Analytics v3中的类索引:
有谁知道这是如何工作的?如何从指定的时间范围内检索访问者的总数?
谢谢
您的问题是您在 data.ga.get 方法中提供指标,而不使用 r.metrics 指标添加更多指标,并用 , 分隔它们。在本例中, ga:visits 是您请求的指标。
var r = gas.Data.Ga.Get("ga:MYProfileID", "2012-01-01", "2014-02-20", "ga:visits");

尺寸不是必填字段,因此您可以删除并 r.Dimensions = "ga:visitCount";
查看返回的内容。
请记住, Google.Apis.Analytics.v3.Data.GaData d = r.Execute();
如果行数多于最大结果集,则简单地执行操作不会返回所有行。您需要检查下一个链接以确保没有更多行。
更新以回答以下有关下一个链接的问题。您当前将max-results设置为 10000,这是一个块中可以返回的最大行数。如果行数超过 10000 行,那么您将获得请求下一行行所需的下一个链接。TotalResult 将为您提供应返回的总行数。下面我不断使用 .execute 请求更多数据,直到不再有 Next 链接。
List result = new List();
do {
try
{
GaData DataList = request.Execute(); // Make the request
result.AddRange(DataList.Rows); // store the Data to return later
// hack to get next link stuff
totalResults = (!DataList.TotalResults.HasValue) ? 0 : Int32.Parse(DataList.TotalResults.ToString());
rowcnt = rowcnt + DataList.Rows.Count;
NextLink = DataList.NextLink;
request.StartIndex = rowcnt + 1 ;
}
catch (Exception e)
{
Console.WriteLine("An error occurred: " + e.Message);
totalResults = 0;
}
} while (request.StartIndex <= totalResults);
