用python调用AlistClient 批量递归下载百度网盘指定目录文件,基于Alist

import os
import requests
from alist import AlistClient
from urllib.parse import unquote, urlparse

def download_file(url, local_path):
    response = requests.get(url, stream=True)
    total_size = int(response.headers.get('content-length', 0))
    downloaded_size = 0
    
    with open(local_path, 'wb') as f:
        for chunk in response.iter_content(chunk_size=8192):
            if chunk:
                f.write(chunk)
                downloaded_size += len(chunk)
                if total_size > 0:
                    percent = downloaded_size * 100 / total_size
                    print(f"\rDownloading: {percent:.1f}% ({downloaded_size}/{total_size} bytes)", end='')
        print()  # 换行

def create_local_path(base_url, url):
    parsed = urlparse(url)
    path = parsed.path
    # 去掉/d/前缀
    if path.startswith('/d/'):
        path = path[3:]
    # 去掉文件名后的参数
    path = path.split('?')[0]
    print(path)
    # 创建本地路径
    local_path = os.path.join('c:/videos/', path)
    print(local_path)
    os.makedirs(os.path.dirname(local_path), exist_ok=True)
    return local_path

client = AlistClient("http://localhost:5244", "admin", "123456")
fs = client.fs
fs.chdir("/")

for path in fs.iter(max_depth=-1):
    if path.name.endswith(".mp4"):
        decoded_url = unquote(path.url)
        if '第2周' in decoded_url:
            print(f"Downloading: {decoded_url}")
            local_path = create_local_path("http://localhost:5244", decoded_url)
            download_file(decoded_url, local_path)
            print(f"Saved to: {local_path}")
        else:
            print(f"Skipping: {decoded_url} (does not contain '第2周')")
