大家好，本篇文章主要講的是用python爬取今日說法每期數(shù)據(jù)，感興趣的同學趕快來看一看吧，對你有幫助的話記得收藏一下

實驗目的

主要是獲取2021年今日說法每期節(jié)目主要內(nèi)容及時間
今日說法的網(wǎng)址為：http://tv.cctv.com/lm/jrsf/index.shtml
當時怎么寫的思路有點不太記得了，先把代碼貼上，后續(xù)有時間再補上。

代碼

import xlwt
import re

import requests


# url = "https://tv.cctv.com/lm/jrsf/index.shtml"

def get_data(page):
    url = 'https://api.cntv.cn/NewVideo/getVideoListByColumn?id=TOPC145146466500891' \
          '4&n=1000&sort=desc&p={pageNo}&mode=0&serviceId=tvcctv&cb=Callback'.format(pageNo=page)
    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 '
                      '(KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36'
    }
    response = requests.get(url=url, headers=headers)
    return response.text
    # print(response.text)


if __name__ == "__main__":

    headers = {
        'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 '
                      '(KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36'
    }

    book = xlwt.Workbook(encoding='utf-8', style_compression=0)
    sheet = book.add_sheet('今日說法', cell_overwrite_ok=True)

    count = 0
    for page in range(1,5):
        page_content = get_data(page)
        obj = re.compile(r'url":"(.*?.shtml)"', re.S)
        imgUrl = re.findall(obj, page_content.replace('\\', ''))
        for i in range(len(imgUrl)):
            resp = requests.get(url=imgUrl[i], headers=headers)
            resp.encoding = 'utf-8'

            obj2 = re.compile(r'更新時間：</em>(.*?)</p>', re.S)
            time = re.findall(obj2, resp.text)
            obj3 = re.compile(r'視頻簡介：</em>(.*?)</p>', re.S)
            jianjie = re.findall(obj3, resp.text)
            content = []
            content.append(time)
            content.append(jianjie)
            for j in range(2):
                sheet.write(count, j, content[j])
                count+=1

    book.save("./data_5.xls")
