화성땅 사기에서 앱파이에 오타가 있는건지... 계속 안되는거 같습니다... 
어디가 오류인지... 
아래쪽 종료코드1 보이는데  flask를 또 깔아야하는 건가요?? 


from flask import Flask, render_template, request, jsonify

app = Flask(__name__)

from pymongo import MongoClient

client = MongoClient('mongodb+srv://test:sparta@cluster0.9rynep1.mongodb.net/cluster0?retryWrites=true&w=majority')
db = client.dbsparta


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


@app.route("/mars", methods=["POST"])
def web_mars_post():
    name_receive = request.form['name_give']
    address_receive = request.form['address_give']
    size_receive = request.form['size_give']


doc = {
    'name': name_receive,
    'address': address_receive,
    'size': size_receive

}
db.mars.insert_one(doc)

 return jsonify({'msg': '주문 완료!'})


@app.route("/mars", methods=["GET"])

    return jsonify({'msg': 'GET 연결 완료!'})

    app.run('0.0.0.0', port=5000, debug=True)
