如何从Unsplash API返回的URL获取图像？

import requests

def download_image(url, file_path):
    response = requests.get(url, stream=True)
    if response.status_code == 200:
        with open(file_path, 'wb') as file:
            for chunk in response.iter_content(1024):
                file.write(chunk)

# 发送GET请求到Unsplash API获取图像URL
api_url = 'https://api.unsplash.com/photos/random'
access_key = 'YOUR_ACCESS_KEY'
response = requests.get(api_url, params={'client_id': access_key})
if response.status_code == 200:
    # 解析API响应并提取图像URL
    data = response.json()
    image_url = data['urls']['regular']

    # 下载图像
    download_image(image_url, 'image.jpg')
