使用API密钥分析报告v4
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，我总是会收到一条错误消息，即validation需要OAuth2。
我需要访问我拥有的特定分析帐户，而不是在CMS中导航的用户帐户！
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 = "<>"; 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 = "<>", DateRanges = new List() { dateRange }, Dimensions = new List() { browser }, Metrics = new List() { sessions } }; List requests = new List(); 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请求缺少必需的身份validation凭据。 预期的OAuth 2访问令牌，登录cookie或其他有效的身份validation凭据。
但是再次使用OAUTH2身份validation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 。
API密钥仅用于访问公共数据，这意味着您只能将其与元数据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服务帐户凭据 。 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。

从我的Google API 报告API API示例项目中删除了代码
创建服务后，您应该可以使用C＃的示例页面上的代码
