实现效果

寻找接口

首先需要用手机分享一个视频的链接出来
此处例子：https://v.douyin.com/JLJyYYr/

然后新建一个无痕窗口，打开开发者工具，设置UA为移动端才可以播放

找到开发者工具的network选项卡，可以发现访问链接以后进行了302跳转，分析一下既可以发现跳转的链接中附带了视频ID，所以我们要获取到这个ID，方法有很多，可以禁止重定向跳转（在请求时加上一个参数：allow_redirects=False），或者不加限制，在请求完成后，返回请求完成的URL，然后拆分一下接口一获取到ID

接下来继续分析一下其他的请求，着重看一下与刚找到ID有关的。然后可以找到以下的链接;

然后查看一下返回的数据：

格式化输出一下，发现了一个这个键值对：

这个就是获取视频的接口了，然后去除水印的话，只需要把接口地址中的playwm替换成play（去掉wm就行）

实现

代码：

import requests
import json
#获取抖音地址
url = input("请输入抖音地址：")
header = {
    "Referer": "https://v.douyin.com/",
    'User-Agent': "Mozilla/5.0 (Linux; Android 8.0.0; Pixel 2 XL Build/OPD1.170816.004) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Mobile Safari/537.36",
}
#获取到视频id
r = requests.get(url, headers = header)
url = r.url
id = url.split("video/")[1].split("/?")[0]
#获取到有水印视频地址
url="https://www.iesdouyin.com/web/api/v2/aweme/iteminfo/?item_ids=" + id
r = requests.get(url, headers = header)
#获取到无水印视频地址
video = json.loads(r.content)["item_list"][0]
url = video["video"]["play_addr"]["url_list"][0]
url = url.replace("playwm","play")
#开始下载
r = requests.get(url,headers = header)
with open(video["desc"]+".mp4", "wb") as code:
     code.write(r.content)
     print("下载成功")
