[항해99 사전준비] 웹개발 종합반 4주차

1. Flask

패키지 설치 -> Flask

• 기본코드 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)

* 프로젝트안에 static, templates 디렉토리 생성

 

2. API 와 클라이언트 연결

• 기본예제 app.py

from flask import Flask, render_template, request, jsonify
app = Flask(__name__)

from pymongo import MongoClient
client = MongoClient('내 URL')
db = client.dbsparta

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

@app.route("/mars", methods=["POST"])
def 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.orders.insert_one(doc)

    return jsonify({'msg': '주문 완료!'})

@app.route("/mars", methods=["GET"])
def mars_get():
    orders_list = list(db.orders.find({},{'_id':False}))
    return jsonify({'orders':orders_list})

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

• index.html (script)

$(document).ready(function () {
            show_order();
        });
function show_order() {
    $('#order-box').empty()
    $.ajax({
        type: 'GET',
        url: '/mars',
        data: {},
        success: function (response) {
            let rows = response['orders']
            for (let i = 0; i < rows.length; i++) {
                let name = rows[i]['name']
                let address = rows[i]['address']
                let size = rows[i]['size']

                let temp_html = `<tr>
                                    <td>${name}</td>
                                    <td>${address}</td>
                                    <td>${size}</td>
                                  </tr>`
                $('#order-box').append(temp_html)
            }

        }
    });
}
function save_order() {
    let name = $('#name').val()
    let address = $('#address').val()
    let size = $('#size').val()

    $.ajax({
        type: 'POST',
        url: '/mars',
        data: { name_give:name, address_give:address, size_give:size },
        success: function (response) {
            alert(response['msg'])
            window.location.reload()
