[英]How to authorize Google anlaytics data api with OAuth2
I am trying to connect to the new Google Analytics Data api using C# to request data from the new google analytics GA4.我正在尝试使用 C# 连接到新的谷歌分析数据 api 以从新的谷歌分析 GA4 请求数据。 The only sample i can find is Quickstart client libraries .net This does work but it uses a service account.
我能找到的唯一示例是快速启动客户端库 .net这确实有效,但它使用服务帐户。 The cloud .net client library google-cloud-dotnet only has examples for using a service account.
云 .net 客户端库google-cloud-dotnet仅包含使用服务帐户的示例。
When i try to pass it desktop app credentials for using Oauth" authorization i get当我尝试传递它使用 Oauth 的桌面应用程序凭据时,我得到了授权

After several hours of digging around i found that you can use ICredential using a builder.经过几个小时的挖掘,我发现您可以使用生成器来使用 ICredential。 This works with a Desktop app credentials, for installed applications.
这适用于已安装的应用程序的桌面应用程序凭据。
