我正在使用新的ReplicaSetConnection方法建立到我的mongodb集群的连接。这个改变实际上归结于用pymongo.ReplicaSetConnection替换pymongo.Connection。我将连接用于我的目的，然后在连接上调用end_request以确保在连接上调用disconnect（）之前刷新连接。这可以确保在长时间运行后，我没有大量半连接的套接字。这在我使用Connection时效果很好，但是当我使用ReplicaSetConnection时，pymongo抱怨说我试图在数据库对象上运行end_request（），尽管事实上我绝对是在调用ReplicaSetConnection对象。这是pymongo中的新东西吗？或者这是驱动程序中的错误？以下是我遇到的问题的手动运行。mongodb：在ReplicaSetConnection上调用end_request会引发数据库错误
>>> import pymongo
>>> s = pymongo.ReplicaSetConnection("192.168.1.1:27017, 192.168.1.2:27017", replicaSet='rep1', safe=True)
>>> s
ReplicaSetConnection([u'192.168.1.1:27017', u'192.168.1.2:27017'])
>>> s.read_preference = pymongo.ReadPreference.SECONDARY
>>> s
ReplicaSetConnection([u'192.168.1.1:27017', u'192.168.1.2:27017'])
>>> type(s)
<class 'pymongo.replica_set_connection.ReplicaSetConnection'>
>>> d = s['test']
>>> s.end_request()
