pymongo升级4.0后的认证问题
最近pip install pymono后，连接时认证出现问题，报了TypeError: 'Collection' object is not callable. If you meant to call the 'authenticate' method on a 'Database' object it is failing because no such method exists.的错
Traceback (most recent call last): File "D:/work/py/test.py", line 37, in <module> admin.authenticate("root", "123456") File "C:\python3\lib\site-packages\pymongo\collection.py", line 2583, in __call__ self.__name) TypeError: 'Collection' object is not callable. If you meant to call the 'authenticate' method on a 'Database' object it is failing because no such method exists.
之前一直这样连接是没有问题的，于是再想是不是版本问题，查找一通文档后，确实是pymongo升级到4.0后的认证方式改变
官方文档中解释如下：
之前的认证方式：
client = pymongo.MongoClient("127.0.0.1", 43127) admin = client.get_database("admin") # 连接所需数据库 admin.authenticate("root", "123456")
解决办法：
1、把pymongo降到4.0以下
pip uninstall pymongo
pip install pymongo==3.xx.xx
2、更改为新的认证方式：
client = pymongo.MongoClient("127.0.0.1", 43127, username="root", password="123456")
