基于bs4中的一个模块BeautifulSoup进行解析数据的一种方法
爬取诗词名句中三国演义小说
1.导入库

import requestsfrom bs4 import BeautifulSoup

2.发起请求

url = 'https://www.shicimingju.com/book/sanguoyanyi.HTML'headers = {        'User-Agent': 'Mozilla/5.0 (windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36 Edg/89.0.774.63'    }resp = requests.get(url=url,headers=headers)

3.BeautifulSoup进行解析数据

#实例化一个BeautifulSoup对象soup = BeautifulSoup(resp,'lxml')#解析出章节标题和详情页urlli_List = soup.select('.book-mulu > ul > li')for li in li_List:    Title = li.a.string    detail_url ='https://www.shicimingju.com/' + li.a['href']    detail_text = requests.get(url=detail_url,headers=headers)	soup_detail = BeautifulSoup(detail_text,'lxml')    content = soup_detail.find('div',class_='chapter_content').text

4.结果发现有数据乱码 进行处理后，代码如下：

import requestsfrom bs4 import BeautifulSoupurl = 'https://www.shicimingju.com/book/sanguoyanyi.HTML'headers = {        'User-Agent': 'Mozilla/5.0 (windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36 Edg/89.0.774.63'    }resp = requests.get(url=url,headers=headers)#处理乱码数据resp.enCoding = 'utf-8'resp.apparent_enCodingresp = resp.text#实例化一个BeautifulSoup对象soup = BeautifulSoup(resp,'lxml')#解析出章节标题和详情页urlli_List = soup.select('.book-mulu > ul > li')for li in li_List:    Title = li.a.string    detail_url ='https://www.shicimingju.com/' + li.a['href']    detail_text = requests.get(url=detail_url,headers=headers)    detail_text.enCoding = 'utf-8'    detail_text.apparent_enCoding  # 处理乱码    detail_text = detail_text.text    soup_detail = BeautifulSoup(detail_text,'lxml')    content = soup_detail.find('div',class_='chapter_content').text    print(Title,content,'\n')

5.总结
BeautifulSoup的一个简单用法，后面继续补充。。。
