스파르타 코딩클럽 수강 4주차 개발일지

스파르타코딩클럽 이현 2021. 7. 30. 03:57

Flask 프레임워크: 서버를 구동시켜주는 편한 코드 모음. 서버를 구동하려면 필요한 복잡한 일들을 쉽게 가져다 쓸 수 있어서 설치해야됨.

 

Flask 서버를 만들 때, 항상, 프로젝트 폴더 안에, ㄴstatic 폴더 (이미지, css파일을 넣어둬야함) ㄴtemplates 폴더 (html파일을 넣어둬야함 *index.html) ㄴapp.py 파일

 

 

from flask import Flask, render_template

app = Flask(__name__)

 

def home():

      return render_template('index.html')

if __name__ == '__main__':

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

 

 

----GET 요청 API코드

@app.route('/test', methods=['GET'])

def test_get():

      title_receive = request.args.get('title_give')

      print(title_receive)

      return jsonify({'result':'success', 'msg': '이 요청은 GET!'})

 

----GET 요청 확인 Ajax코드

$.ajax({

      type: "GET",

      url: "/test?title_give=봄날은간다",

      data: {},

      success: function(response){

      console.log(response) } })

 

----POST 요청 API코드

@app.route('/test', methods=['POST'])

def test_post():

      title_receive = request.form['title_give']

      print(title_receive)

      return jsonify({'result':'success', 'msg': '이 요청은 POST!'})

 

----POST 요청 확인 Ajax코드

$.ajax({

       type: "POST",

       url: "/test",

       data: { title_give:'봄날은간다' },

       success: function(response){

             console.log(response) } })

 

 

준비되면 시작한다.

    1. 클라이언트와 서버 확인하기
    2. 서버부터 만들기  app.py
    3. 클라이언트 만들기 index.html
    4. 완성 확인하기

예시 : app.py

from flask import Flask, render_template, jsonify, request

app = Flask(__name__)

from pymongo import MongoClient

client = MongoClient('localhost', 27017)
db = client.dbhomework


## HTML 화면 보여주기
@app.route('/')
def homework():
return render_template('index.html')


# 주문하기(POST) API
@app.route('/order', methods=['POST'])
def save_order():
name_receive = request.form['name_give']
count_receive = request.form['count_give']
address_receive = request.form['address_give']
number_receive = request.form['number_give']

doc = {
'name' : name_receive,
 'count' : count_receive,
 'address' : address_receive,
 'number' : number_receive,

 }
db.shoporder.insert_one(doc)

return jsonify({'msg': '주문 완료!'})

# 주문 목록보기(Read) API
@app.route('/order', methods=['GET'])
def view_orders():
orders = list(db.shoporder.find({},{'_id':False}))
return jsonify({'all_orders': orders})

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