目标网址:梨视频
然后我们找到科技这一页:https://www.pearvideo.com/category_8。其实你要哪一页都行,你喜欢就行。嘿嘿…
这是动态网站,所以咱们直奔network 然后去到XHR:
找规律,这个应该不难,我就直接贴网址上来咯,想要锻炼的可以找找看哈:
https://www.pearvideo.com/category_loading.jsp"text-align: center">
代码如下:
import requests import parsel,re import os target = "https://www.pearvideo.com/videoStatus.jsp" url = "https://www.pearvideo.com/category_loading.jsp" res = requests.get(url) res.encoding="utf-8" html = parsel.Selector(res.text) lists = html.xpath('/html/body/li/div/a/@href').getall() for each in lists: print("https://www.pearvideo.com/"+each)
output;
https://www.pearvideo.com/video_1703486
https://www.pearvideo.com/video_1703189
https://www.pearvideo.com/video_1703161
https://www.pearvideo.com/video_1702880
https://www.pearvideo.com/video_1702773

顺利拿到,然后进入播放页面,却发现找不到MP4视频,怎么办?经过我一番努力(扯掉了几十根头发后)发现,它在另外一个网址里面
咋办?当然要想办法把这个网址搞到手啦,仔细分析下,发现这个网址非常陌生呀,唯一稍微熟悉点的就是那串数字了,前面我们拿到播放页的网址后面那串数字和这个对比,完全是一模一样的,这样的话那就好搞了,咱们直接用拼接的方式把它接上去就可以了,看代码:
for each in lists: url_num = each.replace('video_',"") urls = target+url_num print(urls) `` ```python output: https://www.pearvideo.com/videoStatus.jsp"text-align: center">恩,很明显,是遇到反爬机制了,这个好搞,要什么给什么就行,代码如下:
headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36', 'Referer': 'https://www.pearvideo.com/video_'+ str(url_num) } html = requests.get(urls,headers=headers).text print(html)搞定!!
最后我们看一下MP4能不能播放:
西八!404!!恩,这里就稍微有点麻烦了,还得找数据,把里面的时间戳改成 ‘cont-数字‘,感觉写了好多,手都有点累了,我就直接上代码了:
import requests import parsel,re import os target = "https://www.pearvideo.com/videoStatus.jsp" url = "https://www.pearvideo.com/category_loading.jsp" res = requests.get(url) res.encoding="utf-8" html = parsel.Selector(res.text) lists = html.xpath('/html/body/li/div/a/@href').getall() # print(lists[2:]) # 提取视频后面的数字,数字是最重要的,需要传给 Referer 和 urls for each in lists: url_num = each.replace('video_',"") urls = target+url_num # print(urls) headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36', 'Referer': 'https://www.pearvideo.com/video_'+ str(url_num) } html = requests.get(urls,headers=headers).text cont = 'cont-' + str(url_num) # 提取 mp4 视频 srcUrl = re.findall(f'"srcUrl":"(.*"',html)[0] # 替换视频里面的时间戳,改为可以真正播放的数据 new_url = srcUrl.replace(srcUrl.split("-")[0].split("/")[-1],cont) print(new_url) # 使用视频后缀当视频名称 filename = srcUrl.split("/")[-1] # 保存到本地 with open("./images/"+filename,"wb") as f: f.write(requests.get(new_url).content)以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
