用Pymongo连接MongoDB取数

2017-11-22

最近有需要用python从MongoDB上取数的需求，于是研究了一下Pymongo，在此做个小记。

from pymongo import MongoClient
client = MongoClient('mongodb://x.x.x.x:xxxxx')

db = client.[DATABASES_NAME]

print(db.collection_names())  # show the names of all the collections in selected database

collections = db[COLLECTION_NAME]

collections.find('{xxx:xxxxx,xxx:xxx}')  # Execute the query, which is equivalent to db.getCollection('xxx').find({})
collections.find_one  #same as db.getCollection('xxx').findOne({})
