本文实例讲述了python将MongoDB里的ObjectId转换为时间戳的方法。分享给大家供大家参考。具体分析如下:

MongoDB里的_id字段前四位是时间戳的16进制表示,通过Python可以很容易从_id中提取出时间戳来

def timestamp_from_objectid(objectid):
 result = 0
 try:
  result = time.mktime(objectid.generation_time.timetuple())
 except:
  pass
 return result

调用方法:

print(timestamp_from_objectid(ObjectId('5217a543dd99a6d9e0f74702')))

返回:1377252547.0

PS:这里再为大家推荐一个本站Unix时间戳转换工具,附带了各种语言(Python/PHP/java/MySQL等)Unix时间戳的操作方法:

希望本文所述对大家的Python程序设计有所帮助。
