[항해99 사전준비] 웹개발종합반 - 4주차 개발일지

2022. 2. 15. 16:36Hanghae99

4주 차 목표

  • Flask 프레임워크를 활용해서 API를 만들기
  • '화성에 땅 사기' API를 만들고 클라이언트에 연결하기
  • '스파르타 피디아' API를 만들고 클라이언트와 연결하기
  • (실습) 팬 방명록 만들기

 

4주 차 실습

 

1. 닉네임과 응원 댓글 db에 저장하기

(index.html)

// script 태그 내부
<script>
function save_comment() {
	let name = $('#name').val()
    let comment = $('#comment').val()

    $.ajax({
    	type: 'POST',
        url: '/homework',
        data: {name_give: name, comment_give: comment},
        success: function (response) {
              alert(response['msg'])
              window.location.reload()
        }
    })
}
</script>

(app.py)

@app.route("/homework", methods=["POST"])
def homework_post():
    name_receive = request.form['name_give']
    comment_receive = request.form['comment_give']

    doc = {
        'name' : name_receive,
        'comment' : comment_receive
    }
    db.guestbooks.insert_one(doc)
    return jsonify({'msg':'저장완료'})

2.  작성한 내용 화면에 보여주기

 

(index.html)

<script>
function show_comment() {
	$.ajax({
    type: "GET",
    url: "/homework",
    data: {},
    success: function (response) {
    	let rows = response['guestbook']
        for (let i = 0; i < rows.length; i++) {
        let name = rows[i]['name']
        let comment = rows[i]['comment']

        let temp_html = `<div class="card">
                           <div class="card-body">
                               <blockquote class="blockquote mb-0">
                                  <p>${comment}</p>
                                  <footer class="blockquote-footer">${name}</footer>
                               </blockquote>
                           </div>
                         </div>`
                         $('#comment-list').append(temp_html)
        }
     }
    });
}
</script>

(app.py)

@app.route("/homework", methods=["GET"])
def homework_get():
    guestbook_list = list(db.guestbooks.find({},{'_id': False}))
    return jsonify({'guestbook':guestbook_list})

결과

 

 

+ ) 개발환경이 Windows에서 Mac으로 최근에 바뀌었는데 로컬에서 포트번호 5000을 사용하고 있다 해서 터미널을 통해

sudo lsof -PiTCP -sTCP:LISTEN

kill [PID]

입력해주었지만 어째서인지 자동 재연결이 되어 port:5000을 사용할 수 없었다. 이 부분에서 시간이 소요되었지만 방법을 찾을 수 없었고 결국 app.py 에서 포트번호를 8000으로 바꾸고 실행시켜주었다. (어떻게든 5000으로 실행 시키고 싶었다,, )
