1.가상환경 설정

$ python -m venv venv

  1. templates 폴더 생성

  2. 설치

$ pip install flask pymongo dnspython requests bs4

조각 기능 구현해보기

BeautifulSoup 기능

or:title, type, image

위의 네이버 영화 페이지 코드를 확인해보면 아래와 같다.
meta 태그가 있는 property가 og인 코드를 확인할 수 있다.

meta태그가 있는 property가 og title인 것을 가져와보자

import requests
from bs4 import BeautifulSoup

url = 'https://movie.naver.com/movie/bi/mi/basic.naver?code=191597'

headers = {'User-Agent' : 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36'}
data = requests.get(url,headers=headers)

soup = BeautifulSoup(data.text, 'html.parser')

ogtitle = soup.select_one('meta[property="og:title"]')
print(ogtitle['content'])

터미널에 출력해보면 아래와 같이 ogtitle이 나온다.

ogtitle, ogdesc, ogimage를 출력해보자

ogtitle = soup.select_one('meta[property="og:title"]')['content']
ogdesc = soup.select_one('meta[property="og:description"]')['content']
ogimage = soup.select_one('meta[property="og:image"]')['content']
print(ogtitle, ogdesc, ogimage)

포스팅 하기(post)

영화 url과 코멘트를 입력 받아서 url에 있는 title, desc, image를 가져온 후 DB에 저장

서버 만들기(app.py)

url기반으로 크롤링 기능 구현

import requests
from bs4 import BeautifulSoup
def movie_post():
    url_receive = request.form['url_give']
    comment_receive = request.form['comment_give']

    headers = {'User-Agent' : 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36'}
    data = requests.get(url_receive, headers=headers)

    soup = BeautifulSoup(data.text, 'html.parser')

    ogtitle = soup.select_one('meta[property="og:title"]')['content']
    ogdesc = soup.select_one('meta[property="og:description"]')['content']
    ogimage = soup.select_one('meta[property="og:image"]')['content']

받은 data 데이터베이스에 넣기
app.py에 import

from pymongo import MongoClient
client = MongoClient('mongodb+srv://sparta:test@cluster0.safzmwr.mongodb.net/?retryWrites=true&w=majority')
db = client.dbsparta
doc = {
     'title' : ogtitle,
     'desc' : ogdesc,
     'image' : ogimage,
     'comment' : comment_receive
}
db.movies.insert_one(doc)

클라이언트 만들기(index.html)

function posting() {
	let url = $('#url').val()
	let comment = $('#comment').val()

	let formData = new FormData();
    formData.append("url_give", url);
    formData.append("comment_give", comment);

    fetch('/movie', { method: "POST", body: formData }).then((res) => res.json()).then((data) => {
		alert(data['msg'])
        window.location.reload()
	})
}

보여주기(get)

서버 만들기

@app.route("/movie", methods=["GET"])
def movie_get():
    all_movies = list(db.movies.find({},{'_id':False}))
    return jsonify({'result': all_movies})

html에 붙여주기

function listing() {
	fetch('/movie').then((res) => res.json()).then((data) => {
    let rows = data['result']
    rows.forEach((a) => {
    	let comment = a['comment']
        let title = a['title']
        let desc = a['desc']
        let image = a['image']
        
        let temp_html = `<div class="col">
        	<div class="card h-100">
            	<img src="${image}"
                	class="card-img-top">
                <div class="card-body">
                	<h5 class="card-title">${title}</h5>
                    <p class="card-text">${desc}</p>
                    <p>⭐⭐⭐</p>
                    <p class="mycomment">${comment}</p>
                </div>
          </div>
     </div>`
     ('#cards-box').append(temp_html)
                    
     })
  })
}

별점 추가

body 태그 내 input-groupt mb-3 클래스 추가

<div class="input-group mb-3">
	<label class="input-group-text" for="inputGroupSelect01">별점</label>
    <select class="form-select" id="star">
    	<option selected>-- 선택하기 --</option>
        <option value="1">⭐</option>
        <option value="2">⭐⭐</option>
