今天闲着没事，用selenium抓取视频保存到本地，只爬取了第一页，只要小于等于5分钟的视频。。。
为什么不用requests，没有为什么，就因为有些网站正则和xpath都提取不出来想要的东西，要么就是接口出来的数据加密，要么就因为真正的视频url规律难找！
selenium几行代码轻轻松松就搞定！
from selenium import webdriver import requests #设置无界面模式 opt=webdriver.ChromeOptions() opt.set_headless() class VideoCrawl(object): video_box=[]#收集video真正的url def __init__(self,url): self.driver=webdriver.Chrome(options=opt)#设置无界面模式 self.driver.get(url) #程序运行完毕，析构函数关闭selenium def __del__(self): print("爬取结束。。。。。",len(VideoCrawl.video_box),VideoCrawl.video_box) self.driver.close() def run(self): self.get_detail_info() #获取列表页所有详情页的url def get_detail_info(self): detail_info = self.driver.find_elements_by_xpath(‘//a[@class="video-wrap statpid"]‘) detail_url=[] for i in detail_info: detail_url.append(i.get_attribute(‘href‘))#获取视频页url video_playtime_list=self.driver.find_elements_by_xpath(‘//span[@class="video-duration"]‘) video_playtime_list=[i.text for i in video_playtime_list] for res in zip(detail_url,video_playtime_list): playtime=res[1].split(":")[0] # print("playtime--------",playtime) if int(res[1].split(":")[0])<=5:#播放时间小于5分钟的要 # print(res[0],"解析的url",playtime) self.parse_video(res[0],res[1]) else: pass #解析详情页 def parse_video(self,url,t): self.driver.get(url) videoobj = self.driver.find_elements_by_xpath(‘//video‘) video_url=videoobj[0].get_attribute(‘src‘) title=self.driver.find_elements_by_xpath(‘//h1[@class="video-title"]‘)[0].text print(‘video_url--------‘,video_url,title,t) #保存video到本地 self.save_video(video_url,title,t) #类变量统计video_url VideoCrawl.video_box.append(video_url) #保存,请求video_url，二进制保存为mp4 def save_video(self,url,title,t): filename="video"+title+"-"+t.replace(":","")+".mp4" video=requests.get(url).content with open(filename,"wb") as file: file.write(video) print(f"{filename}写入文件完毕") if __name__ == ‘__main__‘: crawl=VideoCrawl(‘https://v.huya.com/cat/7‘) crawl.run()
运行结果如下：
