我有两个函数，一个叫做queue_task（），另一个叫做disburse_transaction（）， queue_task只是安排了一个执行disburse_transaction的任务，现在在disburse_transaction内部，正在尝试内发出一个http请求，以防万一发生任何连接异常或任何引发异常的事情，现在在except块内，我想重新运行queue_task，可以吗，如果可以，请问如何存档？
下面是queue_task函数
def queue_task(url,data,method,loan_id):
scheduler.queue_task(disburse_transaction,
pvars=dict(url=url,data=data,method=method,loan_id=loan_id,count=5),
start_time=get_current_date(),
retry_failed=5)
下面是disburse_transaction函数，就像您可以看到int除外块试图重新调用queue_task一样，但是当我检查db.scheduler_task时，没有其他任务了，
def disburse_transaction(url,data,method,loan_id):
# make http request using library requests
trans_rec = db((db.holding_account.loan_id == loan_id) &(db.holding_account.transaction_status == 'Pending')).select().first()
if trans_rec:
loan=db.loan(trans_rec.loan_id)
if method == 'POST':
r =None
try:
r = requests.post(url+'update_customer.php',json.dumps(data))
if int(r.status_code) == 200:
db.holding_account(trans_rec.id).update_record(transaction_status="Completed")
db.commit()
# if Transaction is successful
# Lets get the loan_return period
return_period = loan.loan_return_period
accept_date = get_current_date()
repay_amount = 0.15 * loan.amount + loan.amount
if return_period:
# Now let us copy this loan record to loan_accepted table
add_rec = db.loan_accepted.insert(loan_id=loan.id, status='Under Service',
general_status='Accepted', accept_date=accept_date,
interest_rate=0.15, deadline=add_days(accept_date, return_period),
repay_amount=repay_amount)
db.commit()
if add_rec:
# When all this is done
update = loan.update_record(status='Accepted')
db.commit()
# Send client SMS
# code here
else:
return None
else:
queue_task(url, data, POST_METHOD, loan_id)
except:
queue_task(url, data, POST_METHOD, loan_id)
else:
#chances are 99.9% we shall never fall here
return None
