最近用到了GLASS的LAI产品，但这个产品的文件夹分得很细，我需要的影像又有8个瓦片，一个一个点击很麻烦，于是探索了批量下载的方法

一、下载1幅

import requests
import re
import os
import requests
import re# 网页URLurl = "http://www.glass.umd.edu/LAI/MODIS/250m/2003/009/"  #网址# 本地文件夹路径
local_folder = r"F:\BH\1.data\2.area data\LAI"# 确保本地文件夹存在
if not os.path.exists(local_folder):os.makedirs(local_folder)# 发送HTTP请求获取网页内容
response = requests.get(url)# 使用正则表达式提取文件链接
file_links = re.findall(r'href=[\'"]?([^\'" >]+)', response.text)# 遍历文件链接，下载包含特定关键词的文件 hdf
for file_link in file_links:if ".hdf" in file_link and "h26v05" in file_link:# 下载文件file_url = url + "/" + file_linkfile_name = os.path.join(local_folder, file_link.split("/")[-1])with open(file_name, 'wb') as f:response_file = requests.get(file_url)f.write(response_file.content)print("ok")

二、下载n
