Question

任何人都可以告诉我通过OAuth2生成刷新令牌的到期时间。实际上它通常会返回2个参数访问令牌和刷新令牌。我们使用刷新令牌，以便在访问令牌过期时生成新的访问权限。但谷歌日历版本3，我使用刷新令牌来调用日历API。但是在这里我遇到令牌过期的问题。所以任何人都可以建议我在令牌到期时我该怎么办。据我所知，刷新令牌没有到期时间。请使用刷新令牌检查以下代码以创建日历服务： -

 private CalendarService CreateService(string token)
{        
    KeyValuePair<string, string> credentials = Common.Get3LOCredentials();
    var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description);
    provider.ClientIdentifier = credentials.Key;
    provider.ClientSecret = credentials.Value;
    var auth = new Google.Apis.Authentication.OAuth2.OAuth2Authenticator<NativeApplicationClient>(provider, (p) => GetAuthorization(provider, token));
    CalendarService service = new CalendarService(new BaseClientService.Initializer()
    {
        Authenticator = auth,
        ApiKey = ConfigurationManager.AppSettings["APIkey"].ToString(),
        GZipEnabled = false
    });       
    return service;
}

private static IAuthorizationState GetAuthorization(NativeApplicationClient arg, String Refreshtoken)
{
    IAuthorizationState state = new AuthorizationState(new[] { CalendarService.Scopes.Calendar.GetStringValue() });
    state.Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl);
    state.RefreshToken = Refreshtoken;        
    return state;
}

刷新令牌不会过期，但可以撤销它们。您，令牌处理程序可以revoke the token yourself programatically或最终用户可以revoke the token in their account settings。确保您正确using the refresh token to get a new access token并且您没有尝试使用已过期的访问令牌。

您可以编辑问题以显示您遇到的确切错误吗？
