python连接mongo

1.报错

pymongo.errors.ServerSelectionTimeoutError: s-8vbb1ba3aa777034.mongodb.zhangbei.rds.aliyuncs.com:3717: timed out,s-8vbb2c155414aa44.mongodb.zhangbei.rds.aliyuncs.com:3717: timed out

原因:库里面没有对应的collection!!

2.代码

def init_motor(datas):
# def init_motor():
    db_url='127.0.0.1'
    # db_url='172.26.178.248'

    db=client[db_name][db_collection]
    # 查询测试
    # 查询一个collection
    # num=db.estimated_document_count()
    # print(num)

    # 批量插入
    try:

    except BulkWriteError as e:
