使用 Web 应用程序对“https://accounts.google.com/o/oauth2/token”的 Web 请求失败

Question

我在 GoogleConsoleAPI 中有 SERVICE 帐户。我的控制台应用程序工作正常，我正在从 GoogleAnalytics 获取数据但是当我在 WEB 应用程序中实现相同的代码并尝试访问数据时 我得到了例外

消息 - ProtocolException 被捕获。 对“https://accounts.google.com/o/oauth2/token”的 Web 请求失败。

StackTrace - 在 c:\code.google.com\google-api-dotnet-client\default\Tools\BuildRelease\bin\Release\release140\default 中的 Google.Apis.Requests.ClientServiceRequest`1.Execute() \Src\GoogleApis\Apis\Requests\ClientServiceRequest.cs：第 88 行 在 GoogleAnalyticsDataAccess.GoogleDataAccess.GetDataFromGoogle(GoogleParameterEntity gparamEntity) 在 C:\Users\g.shirpurkar\Documents\Visual Studio 2010\Projects\GoogleAnalyticsDataAccess\GoogleAnalyticsDataAccess\GoogleDataAccess.vb:line 94

有人建议我，对于 web 应用程序，我使用相同的服务帐户。它是否正确 ？如果没有请告诉我步骤，如何解决这个问题？

对我有用的是确保范围设置是这样的： https://www.googleapis.com/auth/analytics.readonly 而不仅仅是“analytics.readonly”
