Flask로 API만들기 과정

필요한 파일 & 폴더
templates - index.html
static (img, css파일)
app.py

Flask, pymongo, dnspython 패키지 설치
mongo DB 사이트 켜둘것

app.py:

from flask import Flask, render_template, request, jsonify
app = Flask(__name__)

from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:[email protected]/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.bluehouse.insert_one(doc)
    return jsonify({'msg':'저장완료'})

@app.route("/homework", methods=["GET"])
def homework_get():
    all_users = list(db.bluehouse.find({}, {'_id': False}))
    return jsonify({'comments':all_users})

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

딕셔너리 따옴표 더 넣었는지, 빼먹지 않았는지 주의
js에서 ; 이거 넣었는지, 안 넣었는지 주의
get과 post의 db이름 통일 --> 이거 안맞추고 있다가 클라이언트 append만 3시간 들여다봄
ajax에서 data={"name_give":name, "comment_give":comment}, <-- 따옴표 넣을 것.
$ 대신 # 넣지않았는지 살펴볼 것

참고:
