python 截取海康威视视频图片代码

以下是 Python 截取海康威视视频图片的代码：

import requests
from urllib.parse import urlencode

# 登录海康威视获取 cookie
login_url = 'http://your_ip_address/ISAPI/Security/userCheck'
login_data = {'userName': 'your_username', 'password': 'your_password'}
response = requests.post(login_url, data=login_data)
cookie = response.headers['Set-Cookie']

# 获取海康威视视频截图
snapshot_url = 'http://your_ip_address/ISAPI/Streaming/channels/101/picture'
snapshot_data = {'videoResolutionWidth': '1920', 'videoResolutionHeight': '1080'}
snapshot_headers = {'Cookie': cookie}
response = requests.get(snapshot_url + '?' + urlencode(snapshot_data), headers=snapshot_headers)

# 保存截图到本地
with open('snapshot.jpg', 'wb') as f:
    f.write(response.content)

请将 `your_ip_address`、`your_username` 和 `your_password` 替换为你自己的海康威视设备的 IP 地址、用户名和密码。
