1. Flask
- API서버를 만들기 위해 자주 사용되는 Python의 마이크로 웹 프레임워크
- 패키지 설치 필요 : 파이참의 경우 file -> setting -> python interpreter
- 폴더생성 필요 : static(이미지,css파일) /tamplates(html파일)
- 기본 코드 : app.py
from flask import Flask
app = Flask(__name__)
@app.route('/')
def home():
return 'This is Home!'
if __name__ == '__main__':
app.run('0.0.0.0',port=5000,debug=True)- POST(API코드(서버)/Ajax코드(클라이언트))
@app.route('/test', methods=['POST']) #요청URL, 요청방식
def test_post():
title_receive = request.form['title_give'] #요청데이터
print(title_receive)
return jsonify({'result':'success', 'msg': '이 요청은 POST!'}) #성공메세지$.ajax({
type: "GET",
url: "/test?title_give=봄날은간다",
data: {},
success: function(response){
console.log(response)
}
})- GET(API코드(서버)/Ajax코드(클라이언트))
@app.route('/test', methods=['GET'])
def test_get():
title_receive = request.args.get('title_give') #요청데이터가 없는경우 없어도 됨
print(title_receive)
return jsonify({'result':'success', 'msg': '이 요청은 GET!'}) #응답데이터를 보내야함$.ajax({
type: "GET",
url: "/test?title_give=봄날은간다",
data: {},
success: function(response){
console.log(response)
}
})2. PyMongo
- 파이썬에서 MongoDB제어하기 위해 사용하는 패키지
- 플라스크와 마찬가지로 패키지 설치 필요
3. 퀴즈 1
- 제목 저자 리뷰를 입력하면 아래 목록에 추가됨
- 예시 : http://spartacodingclub.shop/bookreview
- 서버 코드
from flask import Flask, render_template, jsonify, request
app = Flask(__name__)
from pymongo import MongoClient
client = MongoClient('localhost', 27017)
db = client.dbsparta
## HTML을 주는 부분
@app.route('/')
def home():
return render_template('index.html')
## API 역할을 하는 부분
@app.route('/review', methods=['POST'])
def write_review():
title_receive = request.form['title_give']
name_receive = request.form['name_give']
review_receive = request.form['review_give']
doc = { 'title': title_receive,
'name' : name_receive,
'review' : review_receive
}
db.bookreview.insert_one(doc)
return jsonify({'msg': '저장완료'})
@app.route('/review', methods=['GET'])
def read_reviews():
reviews = list(db.bookreview.find({}, {'_id': False}))
return jsonify({'all_reviews' : reviews})
if __name__ == '__main__':
app.run('0.0.0.0', port=5000, debug=True)- 클라이언트

- 정보(url, review)를 입력하면 해당 url 메타태그에서 이미지와 설명, 제목을 추출하여 카드 목록에 추가함
