写获取抖音用户所有视频代码

抖音用户所有视频的获取需要通过抓取抖音的API来实现。以下是Python代码示例：

import requests

user_id = "抖音用户ID"
sec_uid = "抖音用户sec_uid"

# 设置请求头
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3",
    "Referer": "https://www.douyin.com/",
    "Accept-Encoding": "gzip, deflate, br",
    "Accept-Language": "zh-CN,zh;q=0.9"
}

# 获取用户视频列表
video_list_url = "https://www.iesdouyin.com/web/api/v2/aweme/post/"
params = {
    "user_id": user_id,
    "sec_uid": sec_uid,
    "count": "21",
    "max_cursor": "0",
    "aid": "1128",
    "_signature": "在此处输入_signature参数的值"
}
video_list_response = requests.get(video_list_url, headers=headers, params=params)
video_list_data = video_list_response.json()
video_list = video_list_data["aweme_list"]

# 遍历视频列表获取视频信息
for video in video_list:
    video_url = video.get("video", {}).get("play_addr", {}).get("url_list", [])[0]
    video_desc = video.get("desc", "")
    print(video_url)
    print(video_desc)

需要注意的是，获取用户视频列表需要在请求参数中包含用户ID和sec_uid两个参数。其中_signature参数需要通过抖音的加密算法计算得出，可以通过抓取抖音的APP源代码来获取算法实现。
