我需要在我使用asp.net Web表单(C#)构建的CMS Web应用程序的仪表板页面中集成来自Google Analytics的非常基本的报告.
我记得我能够在2015年使用API?? V3进行的测试中做到这一点,但是现在,使用V4,我总是收到一条错误消息,即验证需要OAuth2.
I need to access to a specific analytics account I own, not the account of the user that navigate in the CMS!
因此,我使用Google API Manager提供的API KEY.我已经给了API Key所有权限.
API密钥类似于：“d471c3ce04612f143ff0Be319aac2e17d0159add”
这是代码
using Google.Apis.AnalyticsReporting.v4;
using Google.Apis.Services;
using System;
using Google.Apis.AnalyticsReporting.v4.Data;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.IO;
using Google.Apis.Auth.OAuth2;
using System.Threading;
using Google.Apis.Util.Store;
using System.Web;
public static class GoogleAnalyticsAPI
{
static string vmcApiKey = "<<API-KEY>>";
public static void Test()
{
AnalyticsReportingService ars = GetService(vmcApiKey);
// Create the DateRange object.
DateRange dateRange = new DateRange() { StartDate = "2017-01-01", EndDate = "2017-04-28" };
// Create the Metrics object.
Metric sessions = new Metric { Expression = "ga:sessions", Alias = "Sessions" };
//Create the Dimensions object.
Dimension browser = new Dimension { Name = "ga:browser" };
// Create the ReportRequest object.
// Create the ReportRequest object.
ReportRequest reportRequest = new ReportRequest
{
ViewId = "<<VIEW-ID>>",
DateRanges = new List<DateRange>() { dateRange },
Dimensions = new List<Dimension>() { browser },
Metrics = new List<Metric>() { sessions }
};
List<ReportRequest> requests = new List<ReportRequest>();
requests.Add(reportRequest);
// Create the GetReportsRequest object.
GetReportsRequest getReport = new GetReportsRequest() { ReportRequests = requests };
// Call the batchGet method.
GetReportsResponse response = ars.Reports.BatchGet(getReport).Execute();
}
public static AnalyticsReportingService GetService(string apiKey)
{
try
{
if(string.IsNullOrEmpty(apiKey))
throw new ArgumentNullException("api Key");
return new AnalyticsReportingService(new BaseClientService.Initializer()
{
ApiKey = apiKey,
ApplicationName = "AnalyticsReporting API key example",
});
}
catch(Exception ex)
{
throw new Exception("Failed to create new AnalyticsReporting Service", ex);
}
}
在Test()方法的最后一行,ars.Reports.BatchGet(getReport).Execute();我收到错误：
Google.Apis.Requests.RequestError
Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential.
但是再次使用OAUTH2身份验证我访问用户数据并不是我想要的.
我需要访问我拥有的特定帐户,由浏览CMS的用户独立访问.
解决方法:
API密钥仅用于访问公共数据,这意味着您只能将其与metadata api一起使用.
Google Analytics数据是用户拥有的私人数据.由于这是您尝试访问的自己的数据,因此您应该创建一个服务帐户.服务帐户是预先授权的.转到Google开发人员控制台并创建service account credentials.然后获取服务帐户电子邮件地址,并将其作为用户添加到Google Analytics分析网站管理部分的ACCOUNT级别.它必须是ACCOUNT级别.您现在已授权服务帐户访问该帐户的数据.
服务帐户验证

从我的Google-api-Dotnet示例项目Reporting API中删除了代码
创建服务后,您应该能够使用样本页面上的代码C#
