python下载文件到指定目录

import requests
import os

def download_file(url, directory):
    # 确保目标目录存在
    if not os.path.exists(directory):
        os.makedirs(directory)

    # 提取文件名
    filename = url.split('/')[-1]
    filepath = os.path.join(directory, filename)

    try:
        # 发送HTTP请求
        response = requests.get(url, stream=True)
        response.raise_for_status()  # 如果请求失败，抛出HTTPError异常

        # 写入文件
        with open(filepath, 'wb') as file:
            for chunk in response.iter_content(chunk_size=8192):
                if chunk:
                    file.write(chunk)
        print(f"文件已成功下载到 {filepath}")
    except requests.exceptions.HTTPError as http_err:
        print(f"HTTP错误发生: {http_err}")
    except Exception as err:
        print(f"其他错误发生: {err}")

# 使用示例
url = 'http://example.com/file.zip'
directory = '/path/to/save'
download_file(url, directory)
