post 연습

요청 정보 : URL= /mars, 요청 방식 = POST
클라(ajax) → 서버(flask) : name, address, size
서버(flask) → 클라(ajax) : 메시지를 보냄 (주문 완료!)

[서버 코드 - app.py]
@app.route("/mars", methods=["POST"])
def mars_post():
    sample_receive = request.form['sample_give']
    print(sample_receive)
    return jsonify({'msg': 'POST 연결 완료!'})
    



[클라이언트 코드 - index.html]
function save_order() {
    $.ajax({
        type: 'POST',
        url: '/mars',
        data: { sample_give:'데이터전송' },
        success: function (response) {
            alert(response['msg'])
        }
    });
}

<button onclick="save_order()" type="button" class="btn btn-warning mybtn">주문하기</button>





- 서버부터 만들기
    - `name`, `address`, `size` 정보를 받아서, 저장
    
    ```python
    @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!'})
    ```
    
- 클라이언트 만들기
    - 이번엔 `name`, `address`, `size` 정보를 보내주자
    
    ```jsx
    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()
            }
        });
    }
    ```

완성 확인하기
- DB에 잘 들어갔는지 확인

get연습

[서버 코드 - `app.py`]

```python
@app.route("/mars", methods=["GET"])
def mars_get():
    return jsonify({'msg': 'GET 연결 완료!'})

[클라이언트 코드 - index.html]

$(document).ready(function () {
    show_order();
});
function show_order() {
    $.ajax({
        type: 'GET',
        url: '/mars',
        data: {},
        success: function (response) {
            alert(response['msg'])
        }
    });
}

서버 만들기

받을 것 없이 orders 에 주문정보를 담아서 내려주기만 하면 된다!

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

클라이언트 만들기

응답을 잘 받아서 for 문으로 붙여주기

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)
            }

        }
    });
}

완성 확인하기

화면을 새로고침 했을 때, DB에 저장된 리뷰가 화면에 올바르게 나타나는지 확인.
