一、步骤

1. 定位到2021必看片
2. 从2021必看片中提取到子页面的链接地址
3. 请求子页面的链接地址。拿到我们想要的下载地址....

二、代码

1、获取页面信息

import requests
import re


headers = {

	"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.54 Safari/537.36 Edg/95.0.1020.40"
}

url = "https://dytt89.com" 

# verify=False 去掉安全验证
resp = requests.get(url,headers=headers,verify=False)
# 指定字符集
resp.encoding = 'gbk'
print(resp.text)

resp.close()

2、获取子页面链接

import requests
import re


headers = {

	"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.54 Safari/537.36 Edg/95.0.1020.40"
}

url = "https://dytt89.com" 

resp = requests.get(url,headers=headers,verify=False)
resp.encoding = 'gbk'

# 匹配子页面链接的标签的正则
obj1 = re.compile(r'2021必看热片.*?<ul>(?P<ul>.*?)</ul>',re.S)
# 匹配子页面链接的正则
obj2 = re.compile(r"<a href='(?P<href>.*?)'",re.S)

result1 = obj1.finditer(resp.text)
for i in result1:
	ul = i.group('ul')
  
        # 提取子页面链接
	result2 = obj2.finditer(ul)
	for j in result2:	
		print(j.group('href'))
	
resp.close()

3、提取数据

import requests
import re


headers = {

	"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.54 Safari/537.36 Edg/95.0.1020.40"
}

url = "https://dytt89.com" 

resp = requests.get(url,headers=headers,verify=False)
resp.encoding = 'gbk'

obj1 = re.compile(r'2021必看热片.*?<ul>(?P<ul>.*?)</ul>',re.S)
obj2 = re.compile(r"<a href='(?P<href>.*?)'",re.S)
obj3 = re.compile(
r'◎片　　名(?P<movie>.*?)<br />.*?'
r'<td style="WORD-WRAP: break-word" bgcolor="#fdfddf"><a href="(?P<download>.*?)&tr'
,re.S)


result1 = obj1.finditer(resp.text)

# 定义一个列表存储子页面链接
Child_Href_list = []

for i in result1:
	ul = i.group('ul')

	result2 = obj2.finditer(ul)	
	for j in result2:
                # 获取完整的子页面链接	
		Child_Href = url + j.group('href')
                # 将链接添加到列表中
		Child_Href_list.append(Child_Href)
		
for k in Child_Href_list:
	Child_Resp = requests.get(k,headers=headers,verify=False)
	Child_Resp.encoding = 'gbk'
        # 提取电影名和种子
	result3 = obj3.search(Child_Resp.text)
	print(result3.group('movie').strip())
	print(result3.group('download'))
	
resp.close()
