I. Grab List
First tap on the Dance section to first select the Otaku Dance list.
Then open F12's control panel and you can find an entry/x/web-interface/newlist?rid=20&type=0&pn=1&ps=20&jsonp=jsonp&callback=jsonCallback_bili_57905715749828263 url, where rid is the subcategory of station B and pn is the number of pages.
I tried to open the address in the browser actually reported 404, but in the control panel the return value of this address is clearly the video list. I tried to remove the callback parameter and got the desired result.
As we all know, bid is the unique ID of a video on B site, to get the bid, we can extract the aid from the return value of the url above, and then convert the aid to bid.
Str = 'fZodR9XQDSUm21yCkr6zBqiveYah8bt4xsWpHnJE7jL5VG3guMTKNPAwcF' # A prepared string of specified characters
Dict = {}
# Put each character of the string into the dictionary one by one, e.g. f for 0 Z for 1 and so on.
for i in range(58):
Dict[Str[i]] = i
s = [11, 10, 3, 8, 4, 6, 2, 9, 5, 7] # Necessary decryption lists
xor = 177451812
add = 100618342136696320 # The string of numbers to be subtracted or added at the end #
def algorithm_enc(av):
ret = av
av = int(av)
av = (av ^ xor) + add
# Convert the format of the BV number (BV + 10 characters) into a list for later manipulation.
r = list('BV ')
for i in range(10):
r[s[i]] = Str[av // 58 ** i % 58]
return ''.join(r)
def find_bid(p):
bids = []
r = (
'/x/web-interface/newlist?&rid=20&type=0&pn={}&ps=50&jsonp=jsonp'.format(p))
data = ()
archives = data['data']['archives']
for item in archives:
aid = item['aid']
bid = algorithm_enc(aid)
(bid)
return bids
Second, get the CID of the video
To download a 1080 video, bid is not enough, you need the SESSDATA value from the login cookie and the cid.
First log in to Site B to copy the SESSDATA from the cookie into the object header. Copy the SESSDATA from the cookie into the object header with the address/x/player/pagelist?bvid= url returns the cid.
def get_cid(bid):
url = '/x/player/pagelist?bvid=' + bid
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36',
'Cookie': 'SESSDATA=182cd036%2C1636985829%2C3b393%2A51',
'Host': ''
}
html = (url, headers=headers).json()
infos = []
data = html['data']
cid_list = data
for item in cid_list:
cid = item['cid']
title = item['part']
({'bid': bid, 'cid': cid, 'title': title})
return infos
III. Download video
video/x/player/playurl Comes from a list of recommendations after each video is played.
Finally, use the function to download the video.
def get_video_list(aid, cid, quality):
url_api = '/x/player/playurl?cid={}&bvid={}&qn={}'.format(cid, aid, quality)
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36',
'Cookie': 'SESSDATA=182cd036%2C1636985829%2C3b393%2A51',
'Host': ''
}
html = (url_api, headers=headers).json()
video_list = []
for i in html['data']['durl']:
video_list.append(i['url'])
return video_list
def schedule_cmd(blocknum, blocksize, totalsize):
percent = 100.0 * blocknum * blocksize/ totalsize
s = ('#' * round(percent)).ljust(100, '-')
('%.2f%%' % percent + '[' + s + ']' + '\r')
()
def download(video_list, title, bid):
for i in video_list:
opener = .build_opener()
= [
('User-Agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36'),
('Accept', '*/*'),

('Referer', '/video/'+bid),
('Origin', ''),
('Connection', 'keep-alive'),
]
filename=('D:\\video', r'{}_{}.mp4'.format(bid,title))
try:
.install_opener(opener)
(url=i, filename=filename, reporthook=schedule_cmd)
except:
print(bid + "Download exception, file:" + filename)
