Flask 시작하기 - 서버만들기

flask 시작코드

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)

 

Flask 시작하기 - HTML파일주기

index.html 예제 코드

<!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/3.4.1/jquery.min.js"></script>

Flask 시작하기 - 본격 API만들기

post요청 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!'})

 

GET요청 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!'})

 

GET요청 확인 Ajax코드

$.ajax({
    type: "GET",
    url: "/test?title_give=봄날은간다",
    data: {},
    success: function(response){
       console.log(response)
    }
  })

 

POST요청 확인 Ajax코드

$.ajax({
    type: "POST",
    url: "/test",
    data: { title_give:'봄날은간다' },
    success: function(response){
       console.log(response)
    }
  })
