Question

我正在尝试从Google AnalyticsAPI中提取一些数据。但是，当我运行应用程序时，我收到403错误 - 执行请求失败：https://www.google.com/analytics/feeds/data?ids=ga:12345678&dimensions=ga:date&metrics=ga:visits&start-date=2014-02-16&end-date=2014-02-19&sort=ga:day

我不确定代码或网址是否有问题？

此行导致错误：

return service.Query(dataQuery);

这是浏览器中的错误：

远程服务器返回错误：（403）Forbidden。

描述：执行期间发生了未处理的异常   当前的网络请求。请查看堆栈跟踪了解更多信息   有关错误的信息以及它在代码中的起源。

Answer 1

403表示您可能无权读取数据。如果您确定使用的是正确的用户名/密码，请确保配置文件ID也正确无误。

当您登录分析时，您的网址类似于https://www.google.com/analytics/web/?hl=en-GB#home/aXXXXXXXXwYYYYYYYYpZZZZZZZZ/

确保您分配给PROFILE_ID的号码是'p'后的号码（在我的情况下为“ga：ZZZZZZZZ”）。

如果这对您没有帮助，我建议您切换到OAuth身份验证，因为您使用的旧方式已被Google弃用，并且无法保证可以正常运行。

Answer 2

我不相信客户登录适用于您需要使用oauth2的Google分析。代码看起来像这样。

UserCredential credential; 
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
          new ClientSecrets { ClientId = "YourClientId", ClientSecret = "YourClientSecret" },
          new[] { AnalyticsService.Scope.AnalyticsReadonly},
          "user",
          CancellationToken.None,
          new FileDataStore("Drive.Auth.Store")).Result; }

一旦您拥有身份验证，您只需要创建所有请求的AnaltyicsService然后通过此服务。

AnalyticsService service = new AnalyticsService(
                           new BaseClientService.Initializer() {
                           HttpClientInitializer = credential,
                           ApplicationName = "Analytics API sample", });
