不同磁力链网站网页内容都不同，需要定制
1，并发爬取
并发爬取后，好像一会就被封了
import requests
from lxml import etree
import re
from concurrent.futures import ThreadPoolExecutordef get_mlink(url, headers):"""输入某影片磁力链所在的网页，返回该网页中的磁力链"""r = requests.get(url, headers=headers)select = etree.HTML(r.text)try:magnetlink = select.xpath('//textarea[@id="magnetLink"]//text()')return magnetlink[0]except AttributeError:return Nonedef get_page_mlinks(url, headers):"""输入某一页搜索结果，返回该网页中所有的元组（url, 影片大小，时间，磁力链）"""r = requests.get(url, headers=headers)select = etree.HTML(r.text)div_rows = select.xpath('//div[@class="row"]')def get_each(se):size = se.xpath('.//div[@class="col-sm-2 col-lg-1 hidden-xs text-right size"]//text()')date = se.xpath('.//div[@class="col-sm-2 col-lg-2 hidden-xs text-right date"]//text()')href = se.xpath('.//a/@href')try:return href[0], size[0], date[0], get_mlink(href[0], headers)except IndexError:passwith ThreadPoolExecutor() as executor: # 并发执行爬取单个网页中所有的磁力链res = executor.map(get_each, div_rows)return resdef get_urls(baseurl, headers, suffix=None):"""输入搜索网页，递归获取所有页的搜索结果"""if suffix:url = baseurl + suffixelse:url = baseurlr = requests.get(url, headers=headers)select = etree.HTML(r.text)page_suffixes = select.xpath('//ul[@class="pagination pagination-lg"]''//li//a[@name="numbar"]/@href')# 有时该站会返回/search/.../search/...search/.../page，需要处理下p = r'/search/[^/]+/page/\d+(?=\D|$)'page_suffixes = [re.search(p, i).group() for i in page_suffixes]# 如果还有下一页，需要进一步递归查询获取r = requests.get(url + page_suffixes[-1], headers=headers)select = etree.HTML(r.text)next_page = select.xpath('//ul[@class="pagination pagination-lg"]''//li//a[@name="nextpage"]/@href')if next_page:page_suffixes = page_suffixes + get_urls(baseurl, headers, next_page[0])return page_suffixesif __name__ == '__main__':keyword = "金刚狼3"baseurl = 'https://*网站url*/search/{}'.format(keyword) # 该站是采用get方式提交搜索关键词headers = {"Accept-Language": "en-US,en;q=0.8,zh-TW;q=0.6,zh;q=0.4"}urls = get_urls(baseurl, headers)new_urls = list(set(urls))new_urls.sort(key=urls.index)new_urls = [baseurl + i for i in new_urls]with ThreadPoolExecutor() as executor:res = executor.map(get_page_mlinks, new_urls, [headers for i in range(7)])for r in res:for i in r:print(i)
2，逐页爬取
手工输入关键词和页数
超过网站已有页数时，返回None
爬取单个搜索页中所有磁力链时，仍然用的是并发
import requests
from lxml import etree
from concurrent.futures import ThreadPoolExecutordef get_mlink(url, headers):"""输入某影片磁力链所在的网页，返回该网页中的磁力链"""r = requests.get(url, headers=headers)select = etree.HTML(r.text)try:magnetlink = select.xpath('//textarea[@id="magnetLink"]//text()')return magnetlink[0]except AttributeError:return Nonedef get_page_mlinks(url, headers):"""输入某一页搜索结果，返回该网页中所有的元组（url, 影片大小，时间，磁力链）"""r = requests.get(url, headers=headers)select = etree.HTML(r.text)div_rows = select.xpath('//div[@class="row"]')def get_each(se):size = se.xpath('.//div[@class="col-sm-2 col-lg-1 hidden-xs text-right size"]//text()')date = se.xpath('.//div[@class="col-sm-2 col-lg-2 hidden-xs text-right date"]//text()')href = se.xpath('.//a/@href')try:return href[0], size[0], date[0], get_mlink(href[0], headers)except IndexError:passwith ThreadPoolExecutor() as executor: # 并发执行爬取单个网页中所有的磁力链res = executor.map(get_each, div_rows)return resif __name__ == '__main__':keyword = input('请输入查找关键词>> ')page = input('请输入查找页>> ')url = 'https://btsow.pw/search/{}/page/{}'.format(keyword, page)headers = {"Accept-Language": "en-US,en;q=0.8,zh-TW;q=0.6,zh;q=0.4"}r = get_page_mlinks(url, headers)for i in r:print(i)
