获取MongoDB内指定数据库的全部集合的名称

import pymongo
from flask import Flask
import pymysql
from pymongo import MongoClient

app = Flask(__name__)



mongo_client = pymongo.MongoClient(host="172.16.31.171",port=27017)
USER_MONGO = mongo_client["DATA"]

def col_names():
    result = USER_MONGO.list_collection_names(session=None)
    return result

print(col_names())

@app.route('/')
def hello_world():
    return 'Hello World!'


if __name__ == '__main__':
    app.run()

以此类推 修改相关MongoDB的配置就可以了
