要获得Vimeo缩略图，我需要哪个代码？

import requests

def get_vimeo_thumbnail(video_id):
    api_url = f"https://vimeo.com/api/v2/video/{video_id}.json"
    response = requests.get(api_url)
    if response.status_code == 200:
        data = response.json()
        thumbnail_url = data[0]['thumbnail_large']
        return thumbnail_url
    else:
        return None

# 示例用法
video_id = "123456789"  # 替换为您要获取缩略图的Vimeo视频ID
thumbnail_url = get_vimeo_thumbnail(video_id)
if thumbnail_url:
    print("Vimeo缩略图URL:", thumbnail_url)
else:
    print("无法获取Vimeo缩略图")
