我有这个 JSON 文件，currencies.json:
{
"AUD": 1.5978,
"BGN": 1.9558,
"BRL": 4.0726,
"CAD": 1.5868,
"CHF": 1.1703,

"CZK": 25.405,
"DKK": 7.4478,
"GBP": 0.87285,
"HKD": 9.6889,
"HRK": 7.4398,
"HUF": 312.9,
"IDR": 16993.0,
"ILS": 4.2984,
"INR": 80.255,
"ISK": 122.1,

"KRW": 1330.3,
"MXN": 22.88,
"MYR": 4.8365,
"NOK": 9.5715,
"NZD": 1.7024,
"PHP": 64.64,

"THB": 38.495,
"TRY": 4.888,

"ZAR": 14.52
}
Python 中的这种连接:
from pymongo import MongoClient
client = MongoClient('localhost', 27017)
db = client['countries_db']
collection_currency = db['currency']
我的数据库名称是 countries_db 与 currency 集合。
有没有办法使用 python 将文件导入数据库？
感谢您的帮助。
最佳答案
您可以使用 insert_one 从文件中读取数据并将其插入到集合中方法:
import json
from pymongo import MongoClient
client = MongoClient('localhost', 27017)
db = client['countries_db']
collection_currency = db['currency']
with open('currencies.json') as f:
file_data = json.load(f)
# if pymongo < 3.0, use insert()
collection_currency.insert(file_data)
# if pymongo >= 3.0 use insert_one() for inserting one document
collection_currency.insert_one(file_data)
# if pymongo >= 3.0 use insert_many() for inserting many documents
collection_currency.insert_many(file_data)
client.close()
