python爬虫爬取某网站视频的示例代码

把获取到的下载视频的url存放在数组中（也可写入文件中），通过调用迅雷接口，进行自动下载。（请先下载迅雷，并在其设置中心的下载管理中设置为一键下载）

实现代码如下：

from bs4 import BeautifulSoup
import requests
import os,re,time
import urllib3
from win32com.client import Dispatch
class DownloadVideo:
  def __init__(self):
    self.r = requests.session()
    self.url=self.get_url()
    self.download_urla=[]
    self.download_urlb=[]
    self.url_set=["%s/shipin/list-短视频.html"%self.url]
  #获取最新网址
  def get_url(self):
    urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
    a=self.r.get('https://www.k58.com',verify=False)
    b=a.url
    return b
  #几页内容的网址
  def url_set1(self,n):
    if n==2:
      url="%s/shipin/list-短视频-2.html"%self.url
      self.url_set.append(url)
    elif n>=3:
      m=n+1
      for i in range(2,m):
        url="%s/shipin/list-短视频-%d.html"%(self.url,i)
        self.url_set.append(url)
    else:
      pass
  #分别加载每一个页内容的网址
  def download_url1(self):
    for j in self.url_set:
      urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
      r=self.r.get(j,verify=False)
      sp1=r.content
      soup = BeautifulSoup(sp1, "html.parser")
      sp2 = soup.find_all(class_="shown")
      for i in sp2:
        url1=re.findall('<a href="(.*?)" rel="external nofollow" ',str(i))
        u=self.url+url1[0]
        self.download_urla.append(u)
  #分别获取各个视频的下载链接
  def download_url2(self):
    for i in self.download_urla:
      urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
      r=self.r.get(i,verify=False)
      sp1=r.content
      soup = BeautifulSoup(sp1, "html.parser")
      sp2 = soup.find_all(class_="form-control input-sm copy_btn app_disable")
      for j in sp2:
        url2=j["data-clipboard-text"]
        self.download_urlb.append(url2)
        #将链接写入txt中
        # self.write_txt(url2)
  #迅雷下载
  def thunder_download(self):
    try:
      thunder = Dispatch("ThunderAgent.Agent64.1")
      for i in self.download_urlb:
        thunder.AddTask(i)
        thunder.CommitTasks()
        time.sleep(2)
    except:
      print("请下载迅雷，并在其设置中心的下载管理中设置为一键下载")

  def mkdir(self,path):
    folder = os.path.exists(path)
    if not folder:
      os.makedirs(path)
    else:
      pass
  def write_txt(self,c):
    self.mkdir(r"D:\AAAAA")
    file_name=time.strftime('%Y%m%d_%H%M%S.txt')
    with open(r"D:\AAAAA\%s"%file_name,'a') as f:
      f.write(c+"\n")

if __name__ == '__main__':
  d=DownloadVideo()
  #数字表示几页的内容
  d.url_set1(5)
  d.download_url1()
  d.download_url2()
  d.thunder_download()
