웹개발 종합반 4주차
2023. 4. 8. 17:16ㆍ항해99
스파르타 코딩클럽 웹개발 종합반 수업내용을 정리한 것입니다.
api 개발 순서
1) 데이터 명세
2) 클라이언트와 서버 확인하기
3) 서버부터 만들기
4) 클라이언트 만들기
5) 완성 확인하기
- 잘 모르는 기능 먼저 만들기
Flask
https://flask.palletsprojects.com/en/2.2.x/quickstart/
Quickstart — Flask Documentation (2.2.x)
Quickstart Eager to get started? This page gives a good introduction to Flask. Follow Installation to set up a project and install Flask first. A Minimal Application A minimal Flask application looks something like this: from flask import Flask app = Flask
flask.palletsprojects.com
- 파일을 만들고 가상환경을 만들어야 한다.
# 터미널
python3 -m venv venv
pip install flask
1) 시작코드
# 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=5001,debug=True)- 맥은 포트 5000 이 안된다.
- localhost:5001 도메인으로 접속하면 사이트를 확인할 수 있다.
from flask import Flask
app = Flask(__name__)
@app.route('/')
def home():
return 'This is Home!'
@app.route('/mypage')
def mypage():
return '<button>버튼입니다</button>'
if __name__ == '__main__':
app.run('0.0.0.0',port=5001,debug=True)
2) HTML 파일 연동
파일 생성
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<title>Document</title>
<script>
function hey() {
alert("안녕!");
}
</script>
</head>
<body>
<button onclick="hey()">나는 버튼!</button>
</body>
</html>from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def home():
return 'This is Home!'
@app.route('/mypage')
def mypage():
return render_template('index.html')
if __name__ == '__main__':
app.run('0.0.0.0',port=5001,debug=True)
3) API 만들기
- GET 요청
- 통상적으로 데이터 조회(Read) 를 요청할 때 사용한다.
- ex) 영화 목록 조회 : 데이터 전달 > URL 뒤에 물음표를 붙여 key=value 로 전달
# app.py
from flask import Flask, render_template, request, jsonify
app = Flask(__name__)
@app.route('/')
def home():
return render_template('index.html')
@app.route('/test', methods=['GET']) # GET 요청으로 test 창구로 들어온다
def test_get():
title_receive = request.args.get('title_give') # title_give 데이터가 있으면 title_receive 변수에 저장
print(title_receive) # 볼 수 있게 출력
return jsonify({'result':'success', 'msg': '이 요청은 GET!'}) # result는 success, msg 는 '이 요청은 GET!' 이렇게 내려준다
if __name__ == '__main__':
app.run('0.0.0.0',port=5001,debug=True)<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<title>Document</title>
<script>
function hey() {
fetch("/test")
.then((res) => res.json())
.then((data) => {
console.log(data);
});
}
</script>
</head>
<body>
<h1>제목을 입력합니다</h1>
<button onclick="hey()">나는 버튼!</button>
</body>
</html>
- POST 요청
- 컴퓨터끼리 알아들을수 있는 방법으로 데이터를 왔다 갔다 함
- 우리 눈에 보이지 않는다.
- 통상적으로 데이터 생성(Create), 변경(Update), 삭제(Delete) 요청할 때 사용
- ex) 회원가입, 회원탈퇴, 비밀번호 수정 : 데이터 전달 > 바로 보이지 않는 HTML
# app.py
from flask import Flask, render_template, request, jsonify
app = Flask(__name__)
@app.route('/')
def home():
return render_template('index.html')
@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!'})
if __name__ == '__main__':
app.run('0.0.0.0',port=5001,debug=True)<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<title>Document</title>
<script>
function hey() {
let formData = new FormData();
formData.append("title_give", "블랙팬서");
fetch("/test", { method: "POST", body: formData })
.then((res) => res.json())
.then((data) => {
console.log(data);
});
}
</script>
</head>
<body>
<h1>제목을 입력합니다</h1>
<button onclick="hey()">나는 버튼!</button>
</body>
</html>- post 는 formData 로 실어나른다.
화성땅 공동구매

여태 배운것들이 손에 익지는 않았는데 같은부분, 비슷한부분을 반복하며 학습할 수 있게 해준 주차 였고 Flask 를 통해 더욱 쉽게 백엔드를 접해볼수 있었던거 같다.
이전에는 주먹구구식으로 api를 만들었지만 api 개발 순서를 보며 변화하며 순서에 맞게 api 를 만들다보니 흥미가 더욱 늘었던 주차였습니다.
