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")
