Practice. MongoDB
Let's update Web crawling data from the previous practice
code
import requests
from bs4 import BeautifulSoup
# 타겟 URL을 읽어서 HTML를 받아오고,
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('https://movie.naver.com/movie/sdb/rank/rmovie.naver?sel=pnt&date=20210829',headers=headers)
# HTML을 BeautifulSoup이라는 라이브러리를 활용해 검색하기 용이한 상태로 만듦
# soup이라는 변수에 "파싱 용이해진 html"이 담긴 상태가 됨
# 이제 코딩을 통해 필요한 부분을 추출하면 된다.
soup = BeautifulSoup(data.text, 'html.parser')
movies = soup.select('#old_content > table > tbody > tr')
for movie in movies:
a = movie.select_one('td.title > div > a')
if a is not None:
title = a.text
rank = movie.select_one('td:nth-child(1) > img')['alt']
star = movie.select_one('td.point').text
print(rank, title, star)
- let's add the basic structure of Pymongo under BeautifulSoup.
from pymongo import MongoClient
client = MongoClient('여기에 URL 입력')
db = client.dbsparta
import requests
from bs4 import BeautifulSoup
from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:sparta@cluster0.grgzlle.mongodb.net/?retryWrites=true&w=majority')
db = client.dbsparta
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('https://movie.naver.com/movie/sdb/rank/rmovie.naver?sel=pnt&date=20210829',headers=headers)
soup = BeautifulSoup(data.text, 'html.parser')
movies = soup.select('#old_content > table > tbody > tr')
for movie in movies:
a = movie.select_one('td.title > div > a')
if a is not None:
title = a.text
rank = movie.select_one('td:nth-child(1) > img')['alt']
star = movie.select_one('td.point').text
print(rank, title, star)
- delete
print(rank, title, star)since we are not usingprint()but updating the data in MongoDB.
Adding to Mongo
# 저장 - 예시 doc = {'name':'bobby','age':21} db.users.insert_one(doc)
-add doc = {}
for movie in movies:
a = movie.select_one('td.title > div > a')
if a is not None:
title = a.text
rank = movie.select_one('td:nth-child(1) > img')['alt']
star = movie.select_one('td.point').text
doc = {
}
- title values should be in 'title'
for movie in movies: a = movie.select_one('td.title > div > a') if a is not None: title = a.text rank = movie.select_one('td:nth-child(1) > img')['alt'] star = movie.select_one('td.point').text doc = { 'title':title }
