POST와 GET 모두 아래와 같은 순서로 만들 것이다.

1. 클라이언트와 서버 연결 확인하기

2. 서버 만들기

3. 클라이언트 만들기

4. 완성 확인하기

▶ POST API 만들기

이름, 주소, 평수 저장하기(Create → POST)

1. 요청 정보: URL= /mars, 요청 방식 = POST

2. 클라이언트(ajax) → 서버(flask) : name, address, size

3. 서버(flask) → 클라이언트(ajax) : 메시지를 보냄 (주문 완료)

* 서버 만들기

→ name, address, size 정보를 받아서 저장

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

    return jsonify({'msg': '주문 완료'})

* 클라이언트 만들기

→ name, address, size 정보 보내기

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()
                }
            });
        }

▶ GET API 만들기

저장된 주문을 화면에 보여주기(Read → GET)

1. 요청 정보: URL= /mars, 요청 방식 = GET

2. 클라이언트(ajax) → 서버(flask) : (없음)

3. 서버(flask) → 클라이언트(ajax) : 전체 주문을 보내주기

* 서버 만들기

→ 받아올 것 없이 orders에 주문 정보를 담아서 내려주기만 하면 됨

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

* 클라이언트 만들기

function show_order() {
            $.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)
                    }
                }
            });
        }

완성된 전체코드이다.
