請安裝anaconda,其中附帶的spyder方便運行完查看變量

1.進入cmd控制臺，

輸入 pip install BeautifulSoup4

pip install requests

2.編寫代碼，代碼已經很清晰了，直接運行不會報錯并有成功的結果def getNewsDetail(newsUrl):

import requests

from bs4 import BeautifulSoup

from datetime import datetime

newsWeb = requests.get(newsUrl)

newsWeb.encoding = 'utf-8'

soup = BeautifulSoup(newsWeb.text,'lxml')

result = {}

result['title'] = soup.select('.main-title')[0].text

result['newsSource'] = soup.select('.source')[0].text

timeSource = soup.select('.date')[0].text

result['datetime'] = datetime.strptime(timeSource,'%Y年%m月%d日 %H:%M')

result['article'] = soup.select('.article')[0].text

result['editor'] = soup.select('.show_author')[0].text.strip('責任編輯：')

result['comment'] = soup.select('.num')[0].text

return result

def parseListLinks(url):

import requests

import json

newsDetails = []

request = requests.get(url)

jsonLoad = json.loads(request.text.lstrip(' newsloadercallback(').rstrip(');'))

newsUrls = []

for item in jsonLoad['result']['data']:

newsUrls.append(item['url'])

for url in newsUrls:

newsDetails.append(getNewsDetail(url))

return newsDetails

if __name__ == '__main__':
