- mongoDB 는 본인의 DB 계정에서의 데이터베이스 URL 을 이용하면 접속 가능합니다

from flask import Flask, render_template, request, jsonify

app = Flask(__name__)

# DB
from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:test@cluster0.wpvuwzi.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

@app.route('/')
def home():
    return render_template('index.html')


@app.route("/homework", methods=["POST"])
def homework_post():

    name_receive = request.form['name_give']
    comment_receive = request.form['comment_give']

    doc = {
        'name': name_receive,
        'comment': comment_receive,
    }

    db.fan.insert_one(doc)
    return jsonify({'msg': 'POST 연결 완료!'})


@app.route("/homework", methods=["GET"])
def homework_get():
    fan_list = list(db.fan.find({}, {'_id':False}))
    # print(fan_list)
    return jsonify({'fans': fan_list})

if __name__ == '__main__':
    app.run('0.0.0.0', port=5000, debug=True)


# 4주차 과제
# 2가지 기능 구현
