获取用户主页分享链接：用户主页右上角点开，获取分享链接

得到类似分享链接：在抖音，记录美好生活！https://v.douyin.com/eSN7g1c/

运行程序，批量下载该用户无水印视频：

获取用户抖音昵称，并创建同名文件夹存放视频

校验用户所有时间段是否发布过视频，校验数量为0则跳过，不为0则进行下载

下载并保存，数量和用户主页视频数量一致

验证一下，确实无水印，bingo！

分享程序思路

1.根据用户页面分享的链接提取url2.根据url来进行请求，通过禁用重定向来获取headers['location'],再从中提取sec_id3.拼接该用户所有视频列表请求url，然后在下载保存即可。下面给出一个请求参数示例：params = { 'sec_uid' : 'MS4wLjABAAAAbtSlJK_BfUcuqyy8ypNouqEH7outUXePTYEcAIpY9rk', #每个用户不同 'count' : '200', #每次请求返回视频list中视频条数，不建议太大 'min_cursor' : '1612108800000',#用户视频开始时间，带毫秒的时间戳 'max_cursor' : '1619251716404',#用户视频结束时间，带毫秒时间戳 'aid' : '1128',#未知参数，可有可无 '_signature' : 'PtCNCgAAXljWCq93QOKsFT7QjR' #签名值，直接从请求参数里面复制一个就能一直用}

关键代码： 1).提取分享链接中的url

string = input('粘贴分享链接：')
shroturl = re.findall('[a-z]+://[\S]+', string, re.I|re.M)[0]

2).请求上述url，禁用重定向获取location的value，在正则提取出sec_id

startpage = requests.get(url=shroturl, headers=headers, allow_redirects=False)
location = startpage.headers['location']
sec_uid = re.findall('(?<=sec_uid=)[a-z，A-Z，0-9, _, -]+', location, re.M|re.I)[0]

3).拼接请求用户信息url，获取用户昵称，也可以获取其他信息，这里只取昵称

getname = requests.get(url='https://www.iesdouyin.com/web/api/v2/user/info/?sec_uid={}'.format(sec_uid), headers=headers).text
userinfo = json.loads(getname)
name = userinfo['user_info']['nickname']

4).创建用户昵称同名文件夹，切换到该路径下

Path = name
if os.path.exists(path=Path) == False:
    os.mkdir(path=Path)
else:
    print('directory exist')
os.chdir(path=Path)

5).视频时间戳生成，原本可以直接使用一个大跨度的时间段，但是在测试中发现时间跨度太大的话，下载的视频数量会变少，多次测试后确定以1个月为间隔，年份从2018到2021，基本上也没有更早的视频了吧

year = ('2018','2019','2020','2021')
month = ('01','02','03','04','05','06','07','08','09','10','11','12')
timepool = [x+'-'+y+'-01 00:00:00' for x in year for y in month ]
print(timepool)
k = len(timepool)
for i in range(k) :
    if i < k-1 :
        print('begintime='+timepool[i])
        print('endtime='+timepool[i+1])
        beginarray = time.strptime(timepool[i], "%Y-%m-%d %H:%M:%S")
        endarray = time.strptime(timepool[i+1], "%Y-%m-%d %H:%M:%S")
        t1 = int(time.mktime(beginarray) * 1000)
        t2 = int(time.mktime(endarray) * 1000)
        print(t1,t2)

6).到这里，params里面的参数都拿到了，直接拼接视频列表url，把返回结果存入json中。

awemeurl = 'https://www.iesdouyin.com/web/api/v2/aweme/post/?'
       awemehtml = requests.get(url=awemeurl, params=params, headers=headers).text
       data = json.loads(awemehtml)

7).直接从json中提取我们要的内容{“视频数量”，“视频title”，“无水印视频url”}，然后还等啥，下载吧

awemenum = len(data['aweme_list'])
        print(awemenum)
        for i in range(awemenum):
            videotitle = data['aweme_list'][i]['desc'].replace("?", "").replace("\"","").replace(":","")
            videourl = data['aweme_list'][i]['video']['play_addr']['url_list'][0]
            start = time.time()
            print('{} ===>downloading'.format(videotitle))
            with open(videotitle+'.mp4', 'wb') as v:
                try:
                    v.write(requests.get(url=videourl, headers=headers).content)
                    end = time.time()
                    cost = end - start
                    print('{} ===>downloaded ===>cost {}s'.format(videotitle, cost))
                except Exception as e:
                    print('download error')
