웹개발 종합반 4주차 개발일지3

4주차 목표

Flask 프레임워크를 사용해서 API를 만들 수 있다.

화성에 땅사기 API를 만들고 클라이언트에 연결한다.

스파르타피디아 API를 만들고 클아이언트와 연결한다.

 

- 스파르타피디아

프로젝트를 세팅하자

3개를 꼭 만들자

패키지도 설치하자 flask, pymongo, dnspython, bs4, requests

 

URL에서 페이지 정보를 가져와보자 meta태그 스크래핑

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')

# 여기에 코딩을 해서 meta tag를 먼저 가져와보겠습니다.
og_image = soup.select_one('meta[property="og:image"]')['content']
og_title = soup.select_one('meta[property="og:title"]')['content']
og_description = soup.select_one('meta[property="og:description"]')['content']

print(og_image)
print(og_title)
print(og_description)

뼈대를 준비하자

app.py

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

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

@app.route("/movie", methods=["POST"])
def movie_post():
    sample_receive = request.form['sample_give']
    print(sample_receive)
    return jsonify({'msg':'POST 연결 완료!'})

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

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

POST 포스팅하기

1. 요청 정보 : URL= /movie, 요청 방식 = POST

2. 클라(ajax) → 서버(flask) : url, star, comment

3. 서버(flask) → 클라(ajax) : 메시지를 보냄 (포스팅 완료!)

 

서버

@app.route("/movie", methods=["POST"])
def movie_post():
    url_receive = request.form['url_give']
    star_receive = request.form['star_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')

    og_image = soup.select_one('meta[property="og:image"]')
    og_title = soup.select_one('meta[property="og:title"]')
    og_description = soup.select_one('meta[property="og:description"]')

    image = og_image['content']
    title = og_title['content']
    description = og_description['content']

    doc = {
        'image':image,
        'title':title,
        'desc':description,
        'star':star_receive,
        'comment':comment_receive
    }

    db.movies.insert_one(doc)

    return jsonify({'msg':'POST 연결 완료!'})

클라이언트

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

    $.ajax({
        type: 'POST',
        url: '/movie',
        data: {url_give: url, star_give: star, comment_give: comment},
        success: function (response) {
            alert(response['msg'])
            window.location.reload()
        }
    });
}

GET 보여주기

1. 요청 정보 : URL= /movie, 요청 방식 = GET

2. 클라(ajax) → 서버(flask) : (없음)

3. 서버(flask) → 클라(ajax) : 전체 영화를 보내주기

 

서버

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