cancelleError:API调用日志服务。刷新（）被显式取消如何刷新gae中的日志以防止此错误？

Question

实际上，我面临着一个与此类似的问题post。我的应用程序能正常运行10分钟，但过了这段时间后，我总是会遇到这样的错误：

我正在使用cron作业调用页面。然后，此页面将启动一个任务队列（推送）。在这里，我试图覆盖自动刷新设置，但没有达到任何改善。在

^{pr2}$

在这个队列中有一个递归方法，它在尚未到达最终状态的情况下调用自己。如您所见，我已经尝试手动刷新日志，但没有任何效果。有人知道该怎么做吗？提前谢谢！在

def detectClosingValue():
    logging.info('detectClosingValue started')
    query = "SELECT * FROM DaxValue WHERE date = DATE('%s')" % str(datetime.datetime.now().date())
    q = db.GqlQuery(query)
    daxValue = q.get()
    if not daxValue.isTradingDay:
        return False

    else:
        previous = getLatestValue()[0]
        time.sleep(5)
        i = 1

        while i < 10:
            logservice.flush()
            logging.info("retrieved close %d value at %s" % (i, str(previous)))
            if previous != getLatestValue()[0]:
                time.sleep(25)
                detectClosingValue()
            i += 1
            time.sleep(10)

        daxValue = q.get()
        daxValue.close = getLatestValue()[0]
        daxValue.high = getLatestValue()[3]
        daxValue.low = getLatestValue()[2]
        daxValue.opn = getLatestValue()[1]
        daxValue.popDate = datetime.datetime.now()
        daxValue.put()
        logging.info("stored close value at %s" % str(daxValue.close))
        return True

根据this post，当使用队列中的日志引发{}时，就会发生该错误。在

如果你的应用程序只运行了10分钟，那么试着少运行一点，比如9:55分钟，以允许日志被正确刷新。在
