import requests

from lxml import etree

class Spider(object):

def __init__(self):

self.headers = {"User-Agent":"Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36"}

self.offset = 1

def start_work(self, url):

print("正在爬取第 %d 页......" % self.offset)

self.offset += 1

response = requests.get(url=url,headers=self.headers)

html = response.content.decode()

html = etree.HTML(html)

video_src = html.xpath('//div[@class="video-play"]/video/@src')

video_title = html.xpath('//span[@class="video-title"]/text()')

next_page = "http:" + html.xpath('//a[@class="next"]/@href')[0]

# 爬取完毕...

if next_page == "http:":

return

self.write_file(video_src, video_title)

self.start_work(next_page)

file_name = title + ".mp4"

file_name = "".join(file_name.split("/"))

print("正在抓取%s" % file_name)

with open(file_name, "wb") as f:

f.write(response.content)

if __name__ == "__main__":

spider = Spider()

for i in range(0,3):

# spider.start_work(url="https://ibaotu.com/shipin/7-0-0-0-"+ str(i) +"-1.html")

t = threading.Thread(target=spider.start_work, args=("https://ibaotu.com/shipin/7-0-0-0-"+ str(i) +"-1.html",))

t.start()
