以下示例显示如何使用Oauth2为已安装的应用授权Google cloud resource manager API。

// Key file from google developer console (INSTALLED APP)
var PathToInstalledKeyFile = @"C:\Development\FreeLance\GoogleSamples\Credentials\credentials.json";

// scope of authorization needed for the method in question.
var scopes = "https://www.googleapis.com/auth/cloud-platform";

// Installed app authorizaton.
var credential = GoogleWebAuthorizationBroker.AuthorizeAsync(GoogleClientSecrets.FromFile(PathToInstalledKeyFile).Secrets,
    new []{  scopes },
    "userName",
    CancellationToken.None,
    new FileDataStore("usercreds", true)).Result;

var client = new ProjectsClientBuilder()
{
    Credential = credential,
}.Build();

var projects = client.ListProjects(new FolderName("123"));

注意对于一个web应用程序来说代码是不同的。Web授权和客户端库是不一样的。我以前没有尝试过通过web oauth连接任何云api。
