小鹅通 pri-cdn-tx.xiaoeknow.com开头的视频下载方法
环境
方法一：手动抓包拼接下载地址
pri-cdn-tx.xiaoeknow.com开头的视频，m3u8文件中ts地址是加密的，没有办法直接提取出来替换
1.解析sign、us
def get_detail_info(self, resource_id):
"""
提取视频原始下载地址和参数：
'param': '?sign=8c366cd81db547a00172a39d032444f0&t=63948ea8&us=bvZemXXVQx'
"""
headers = {
'user-agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Mobile Safari/537.36 Edg/105.0.1343.33',
'cookie': self.cookie
}
data = {
'bizData[resource_id]': resource_id,
'bizData[product_id]': self.product_id,
'bizData[opr_sys]': 'Win32'
}
response = requests.post(url, headers=headers, data=data)
response = response.json()
video_info = response['data']['video_info']
video_length = video_info['video_length']
file_name = video_info['file_name']
video_urls = response['data']['video_urls']
# m3u8 解密
video_urls = json.loads(self.dec_m3u8(video_urls))
results = []
for video_url in video_urls:
host = video_url['ext']['host']
path = video_url['ext']['path']
baseuri = host + '/' + path + '/'
param = '?' + video_url['ext']['param']
m3u8url = video_url['url']
# print(baseuri, param)
info = {
'm3u8url': m3u8url,
'baseuri': baseuri,
'param': param,
'file_name': file_name
}
results.append(info)
return results
2.去视频播放页面抓包，随便抓一个ts链接
3.手动拼接完整m3u8地址
加密参数：
sign=1cedf0ef8927be6e5ac8fb12ec86d44e&t=63974ac0&us=tPzxDODjWL
ts地址：
https://encrypt-k-vod.xet.tech/2919df88vodtranscq1252524126/ab176def5285890794132337419/drm/v.f230.ts?start=0&end=196655&type=mpegts&sign=3f0b7ebfaa621ee2d9ac9dd5266b635c&t=63974e6c&us=VyiZZyhZvP
方法二：根据视频信息脚本自动导出下载地址
# 店铺IP
APPID = 'appsw2t0vpw1085'
# 视频id
# resource_id = 'v_637cc24ee4b0edc794f95a2a'
# 专栏id
product_id = 'p_5d8f2045bcc1d_i2P94QXd'
# 登录cookie
COOKIE = 'ko_token=354b9d9b1708677a7ed5a5b7ff29754f'
1.获取指定专栏下所有视频id
def get_h5_resource(self):
"""
根据课程ID获取课程目录：H5页面 网页端
ko_token：随便抓个1.0或者2.0的包，提取token
column_id：课程ID
"""
cookie = str(self.cookie).split('=')[1]
headers = {
"Host": "appav87zodt7514.h5.xiaoeknow.com",
"sec-ch-ua": "\"Chromium\";v=\"106\", \"Google Chrome\";v=\"106\", \"Not;A=Brand\";v=\"99\"",

}
data = {
"bizData[column_id]": self.product_id, # 课程ID
"bizData[page_index]": "1",
"bizData[page_size]": "20",
"bizData[sort]": "desc"
}
response = requests.post(url, headers=headers, cookies=cookies, data=data)
total = response.json().get("data").get("total")
print(f'共：{total} 节课程')
data = response.json().get("data").get("list")
resource_title = [i.get("resource_title") for i in data]
resource_id = [i.get("resource_id") for i in data]
for i in zip(resource_title, resource_id):
print(i)
yield i
2.提取视频原始下载参数，及加密参数
def get_detail_info(self, resource_id):
"""
提取视频原始下载地址和参数：
'param': '?sign=8c366cd81db547a00172a39d032444f0&t=63948ea8&us=bvZemXXVQx'
"""
headers = {
'user-agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Mobile Safari/537.36 Edg/105.0.1343.33',
}
data = {
'bizData[resource_id]': resource_id,
'bizData[product_id]': self.product_id,
'bizData[opr_sys]': 'Win32'
}
response = requests.post(url, headers=headers, data=data)
response = response.json()
video_info = response['data']['video_info']
video_length = video_info['video_length']
file_name = video_info['file_name']
video_urls = response['data']['video_urls']
# m3u8 解密
video_urls = json.loads(self.dec_m3u8(video_urls))
results = []
for video_url in video_urls:
host = video_url['ext']['host']
path = video_url['ext']['path']
baseuri = host + '/' + path + '/'
param = '?' + video_url['ext']['param']
m3u8url = video_url['url']
# print(baseuri, param)
info = {
'm3u8url': m3u8url,
'baseuri': baseuri,
'param': param,
'file_name': file_name
}
results.append(info)
return results
3.提取ts加密文件并拼接下载地址
# 下载m3u8文件
response = requests.get(m3u8url).text
# 解key 不用key也能下载
# keyurl = re.findall('URI="(.+?)"',response)[0] + f'&uid={USERID}'
# key = base64.b64encode(requests.get(keyurl).content).decode()
# print(f'key: {key}')
# 找到一个ts链接去生成m3u8链接
# 普通视频提取ts文件
# temp_url = re.findall('#EXTINF.+\n(.+?)_.+\?start=',response,re.DOTALL)[0] + '.m3u8'
# https://pri-cdn-tx.xiaoeknow.com域名的视频提取ts文件：v.f230.m3u8
temp_url = re.findall(',+\n(.+?).ts\?start=', response, re.DOTALL | re.M | re.S)[0] + '.m3u8'
print(temp_url)
# 替换m3u8域名地址，构造下载m3u8视频下载地址
m3u8url = self.decrypt(baseuri + temp_url + param)
print(file_name, m3u8url)
效果
