1. POST

 

서버만들기(app.py)

from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:sparta@cluster0.hxjcjic.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

dbprac에서 db에 연결하기 위해 mongodb 가져오기 

 

 

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

    doc = {
        'name':name_receive,
        'comment':comment_receive,
    }
    db.fan.insert_one(doc)
    return jsonify({'msg':'응원 남기기 완료!'})

클라이언트에서(index_html) 받아와야될 값 name_give, comment_give  변수 선언

DB에 저장해야되니 doc = { name : 저장될 값 }

db.db에 저장될 폴더 이름.insert_one(doc)

msg : 저장된 후 사용자에게 완료 메세지 보여주기

 

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

from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:sparta@cluster0.hxjcjic.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta


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

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

    doc = {
        'name':name_receive,
        'comment':comment_receive,
    }
    db.fan.insert_one(doc)
    return jsonify({'msg':'응원 남기기 완료!'})

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

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

완성코드(app.py)

 

 

 

 

클라이언트(index.html) 만들기

 

input // id="name", id="comment" 값 확인

 

 

function save_comment(){
    let name = $('#name').val()
    let comment = $('#comment').val()

가져와야되는 데이터 변수선언 $('#id값')

 

$.ajax({
type: 'POST',
url: '/fan',
data: { name_give:name, comment_give:comment},

app.py(서버)가 가져오라는 데이터 값 name_give, comment_give 입력

 

success: function (response) {
alert(response['msg'])

window.location.reload()

입력이 완료되면 메세지와 새로고침

입력

 

DB에 저장된 값 확인

 

2. GET(보여주기) 

 

서버만들기

 

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

 

새로고침 후 잘 연결 됫는지 확인

 

여러개 찾기 복사 후 app.py GET 추가

 

@app.route("/fan", methods=["GET"])
def pan_get():
    fan_list = list(db.fan.find({}, {'_id': False}))
    return jsonify({'fans':fan_list})

all_users 변수 이름 fan_list 변경 

db.users.find -> db.fan.find 변경 ( db 어디다가 저장할지 체크 ) 

'fans':fan_list // fans라는 키로 fan_list를 받아옴

 

 

 

클라이언트 만들기

 

 

function show_comment(){
$.ajax({
type: "GET",
url: "/fan",
data: {},
success: function (response) {
console.log(response)

console.log 찍어 보기

 

app.py에서 만들어둔 fans 값 db에 연동 잘 되는지 확인
하나 추가해서 확인 한번 더 해보기
추가된거 확인

 

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

        console.log(name,comment)

    }
}
});
}

 

for문으로 콘솔 찍어서 확인

 

 

붙여줘야 되는 곳, id값 확인

 

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)

temp_html 작성 

아까 확인 했던 id 값 $('#commnet-list') 넣어주고 . append(teml_html)

 

기존에 있던건 삭제

 

db에 있는 값 잘 읽어오는 모습

 

테스트로 추가 해보기

 

추가 된 모습
