代码如下
static void Main(string[] args)
{
// Register the authenticator. The Client ID and secret have to be copied from the API Access
// tab on the Google APIs Console.
var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description);
provider.ClientIdentifier = "272908629865.apps.googleusercontent.com";
provider.ClientSecret = "4UmdiNDILOV5bv-qRQz2XUwA";
var auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthentication);
// Create the service and register the previously created OAuth2 Authenticator.
var service = new TasksService(auth);
TaskLists results = service.Tasklists.List().Fetch();
foreach (TaskList list in results.Items)
{
Console.WriteLine(list.Title);
}
}
private static IAuthorizationState GetAuthentication(NativeApplicationClient arg)
{
// Get the auth URL:
IAuthorizationState state = new AuthorizationState(new[] { TasksService.Scopes.Tasks.ToString() });
state.Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl);
Uri authUri = arg.RequestUserAuthorization(state);
// Request authorization from the user (by opening a browser window):
Process.Start(authUri.ToString());
Console.Write(" Authorization Code: ");
string authCode = Console.ReadLine();
Console.WriteLine();
// Retrieve the access token by using the authorization code:
return arg.ProcessUserAuthorization(authCode, state);
}
运行

Process.Start(authUri.ToString());时浏览器里面的结果是：
OAuth2.0 错误：invalid_scope You can email the developer of this application at:[email protected] Some requested scopes were invalid. {invalid=[Tasks]}
