Question

我在日期比较方面遇到了一些问题。功能检查域和时间的DB，如果找不到域，则执行代码并插入到DB中。如果存在域和日期，则检查日期是否早于24小时并执行功能。

数据库条目如下所示：

domain          inform_date
pl23.domain.lt  1426690221

功能是：

### Inform function
def information( domain ):
  inform_timelimit = now - (inform_time*3600)
  cur.execute("SELECT inform_date FROM php_inform_date WHERE `domain` = %s", (domain))
  time_send = cur.fetchone()
  if time_send == None:
    cur.execute("REPLACE INTO php_inform_date VALUES (%s, %s)", (domain, now))
    (...)
  if inform_timelimit > time_send[0]:
    cur.execute("REPLACE INTO php_inform_date VALUES (%s, %s)", (domain, now))
    (...)

变量timelimit是unixtime：

now = int(time.time())
inform_timelimit = now - (24*3600)

找到域时出错：

Traceback (most recent call last):
  File "/opt/php-secure-sendmail/secure_sendmail.py", line 84, in <module>
    information(domain)
  File "/opt/php-secure-sendmail/secure_sendmail.py", line 41, in information
    if inform_timelimit > time_send[0]:
TypeError: 'NoneType' object is unsubscriptable

PS。抱歉我的英语不好;）

我找到了解决方案。只需改变逻辑：

### Inform function
def information( domain ):
  cur.execute("SELECT inform_date FROM php_inform_date WHERE `domain` = %s", (domain))
  time_send = cur.fetchone()
  ### if no information about time in DB do action:
  if time_send == None:
    (.....)
  else:
    ### if found entry, then check 24 hour limit / inform_time - includet from config file (24 hours / or can change)
    inform_timelimit = now - time_send[0]
    if inform_timelimit > inform_time:
      (.....)

Python unixtime比较
