mongodb - MongoClient insert_one 工作，而 mongoengine 连接不工作（未经授权）

Question

我尝试在身份验证后使用 mongoengine 接口插入文档，但仍然被拒绝。使用 MongoClient 不会发生这种情况......

这是 mongoengine 尝试插入一个文档：

In [1]: from mongoengine import connect

In [2]: db = connect(host='localhost', port=27017, username='root', password='pass')

In [3]: db.local.col.insert_one({'a':1})

失败了，但 MongoClient 出于某种原因工作：

In [4]: from pymongo import MongoClient

In [5]: col = MongoClient(host='localhost', port=27017, username='root', password='pass')

In [6]: col.local.col.insert_one({'a':1})
Out[6]: <pymongo.results.InsertOneResult at 0x7ff2a347a8c0>
