爬虫-简单爬取视频

Posted 2020-11-22 xiaowangba9494

 

1、请求Headers里

 

URL请求地址，分析得出加载视频个数

1625830,1625746,等等为加载更多视频过滤条件

 

2、去除后缀，拿原始链接可以请求数据

分析得知start=0 为第一个视频

 

3、查看源代码，下面为真实数据请求地址

 

 

4、代码

# 获取视频
import re
res = requests.get(‘https://www.pearvideo.com/category_loading.jsp?reqType=5&categoryId=1&start=0‘)

reg_text =‘<a href="(.*?)" class="vervideo-lilink actplay">‘
obj = re.findall(reg_text,res.text)
print(obj) # ‘video_1626266‘列表集合

for url in obj:
    url = ‘https://www.pearvideo.com/‘+url
    res1 = requests.get(url)
    # 获取真实的视频资源请求地址
    obj1 = re.findall(‘srcUrl="(.*?)"‘,res1.text)
    print(obj1) # [‘https://video.pearvideo.com/mp4/adshort/20191125/cont-1626232-14630171_adpkg-ad_hd.mp4‘]
    name = obj1[0].rsplit(‘/‘,1)[1]
    print(name) # cont-1626232-14630171_adpkg-ad_hd.mp4
    # 发送请求资源
    res2 = requests.get(obj1[0])
    with open(name,‘wb‘)as f:
        # 流式保存
        for line in res2.iter_content():
            f.write(line)
