It is my first time to public some notes on this platform, and I just want to improve myself by recording something that I learned everyday.
Partly , I don't know much about network crawler , and that makes me just understanding something that floats on the surface.
But since I was learning three days when I got a method to craw some videos on the web.
I am very excited, I just know how to craw something from the internet to computer hard disk. It is a start, surely, this is the first step, I just got to keep moving.
Step 1: Find a video on the web page, then plays the video online, press the keyboard shortcuts F12, it occurs element-checked page
as the following pictures:
Click .ts file and then you will see the URL, that is the point.
Step 2: Writing python code, as following:
1 from multiprocessing import Pool 2 import requests 3
4
5 def demo(i): 6 try: 7 url = "https://vip.holyshitdo.com/2019/5/8/c2417/playlist%0d.ts"%i 8 #simulate browser
9 print(url) 10 headers={'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36Name','Referer':'http://91.com','Content-Type': 'multipart/form-data; session_language=cn_CN'} 11 r = requests.get(url, headers=headers) 12 #print(r.content) save the video with binary format
13 with open('./mp4/{}'.format(url[-10:]),'wb')as f: 14 f.write(r.content) 15 except: 16 return ""
17
18
19 if __name__=='__main__': # program entry
20 pool = Pool(10) # create a process pool
21 for i in range(193): 22 pool.apply_async(demo,(i,)) # execute
23
24
25 pool.close() 26 pool.join()
Step 3:Running code
Step 4 : Last but not least, merge .ts fragments into MP4 format.
Get to the terminal interface , under the saved diretory and use command line "copy /b *.ts newfile.mp4"
