웹개발 4주차

1. flask 를 이용한 개발환경 만들기. app.py // static // templates(index.html)

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

from pymongo import MongoClient
client = MongoClient('localhost', 27017)
db = client.dbsparta

## HTML을 주는 부분
@app.route('/')
def home():
    return render_template('index.html')

## API 역할을 하는 부분

@app.route('/review', methods=['POST'])
def write_review():
    sample_receive = request.form['sample_give']
    print(sample_receive)
    return jsonify({'msg': '이 요청은 POST!'})


@app.route('/review', methods=['GET'])
def read_reviews():
    sample_receive = request.args.get('sample_give')
    print(sample_receive)
    return jsonify({'msg': '이 요청은 GET!'})


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

import requests
from bs4 import BeautifulSoup

url = 'https://movie.naver.com/movie/bi/mi/basic.nhn?code=171539'

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')

#### 여기에 코딩을 해서 meta tag를 먼저 가져와보겠습니다.

```python
url_image = og_image['content']
url_title = og_title['content']
url_description = og_description['content']

print(url_image)
print(url_title)
print(url_description)
```
#### 가져온 meta tag의 content를 가져와봅시다.

url_image = og_image['content']
url_title = og_title['content']
url_description = og_description['content']

print(url_image)
print(url_title)
print(url_description)
