c# - Windows 服务停止

Question

我有一个 Windows 服务，该服务应该以一定的时间间隔运行(目前出于测试目的设置为 1 分钟)，并从我们的数据库获取数据，然后将信息上传到我们的 Google 日历。在 Debug模式下，一切运行良好，但是当 Windows 服务在我的 PC 上自行运行时，它似乎在“Inside StartGoogleCalendar”EventLog 条目处停滞。为什么它在 Debug模式下运行得很好，但在生产模式下却停滞不前？难道我做错了什么？下面是代码。

protected override void OnStart(string[] args)
{
    EventLog.WriteEntry("Service Started: " + DateTime.Now.ToLongDateString());
    _timer = new System.Timers.Timer(1 * 60 * 1000);
    _timer.Elapsed += new System.Timers.ElapsedEventHandler(fireGoogle);
    _timer.Start();
}

protected override void OnStop()
{
    EventLog.WriteEntry("Service Stopped: " + DateTime.Now.ToLongDateString());
}

private void fireGoogle(object sender, System.Timers.ElapsedEventArgs e)
{
    EventLog.WriteEntry("Firing Google: " + DateTime.Now.ToLongDateString());
    StartGoogleCalendar();
}

public void StartGoogleCalendar()
{
    try
    {
        EventLog.WriteEntry("Inside StartGoogleCalendar");
        authorization Auth = new authorization();
        EventLog.WriteEntry("Done with Auth");
        calendar ipamCal = new calendar();
        EventLog.WriteEntry(Auth.EventLogEvent());
        EventLog.WriteEntry("GAPI Calendar Schedule complete");
    }
    catch (Exception ex)
    {
        EventLog.WriteEntry(ex.Data.ToString() + ": INNER EXCEPTION: " + ex.InnerException.ToString() + " - GENERAL MESSAGE: " + ex.Message.ToString() + " - SOURCE: " + ex.Source.ToString() );
    }
}

这是“授权”代码(client_secrets.json 确实存在，因为它在 Debug模式下工作):

    private static EventLog _el = new EventLog();
    public authorization()
    {
        globals.scopes = new List<string>();
        _authCredentials();
    }

    private void _authCredentials()
    {
        globals.scopes.Add("https://www.googleapis.com/auth/calendar");

        try
        {
            _el.WriteEntry("Inside _authcredentials");
            using (FileStream _stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
            {
                _el.WriteEntry("Attempting to get credentials");
                globals.userCredentials = GoogleWebAuthorizationBroker.AuthorizeAsync(GoogleClientSecrets.Load(_stream).Secrets, globals.scopes, "Today-at-IPAM", CancellationToken.None, new FileDataStore("calendar_new.dat")).Result;
                _el.WriteEntry(globals.userCredentials.Token.ToString());
            }

            _el.WriteEntry( "Google Authorization - SUCCESS");
        }
        catch (Exception ex)
        { _el.WriteEntry( "Google Authorization - FAILED\r\n\tReason: " + ex.InnerException.Message); }
    }

    public String EventLogEvent()
    { return globals.eventLogEvents; }

您必须测试几件事: 1/在windows系统中添加服务时是否指定了完整的执行路径 请引用命令行。 SC CREATE "ServiceName"DisplayName= "显示服务名称"binpath= "C:\User\Service.exe"start= auto obj= "NT AUTHORITY\LocalService"

2/您用来启动服务的帐户是什么，权限是否正确？ 请引用上例中的参数obj。

3/“client_secrets.json”目录和文件的权限是什么
