要使用requests库下载文件,通常的做法是发送一个GET请求到目标URL,并将响应内容写入文件。下面是一个基本的示例: importrequestsdefdownload_file(url, filename): response = requests.get(url)withopen(filename,'wb')asf: f.write(response.content) download_file('https://example.com/file.zip','file.zip'...
2. 用requests模块 requests模块是最流行的库之一,安装它非常简单:pip install requests。 import requests url = 'https://example.com/file.txt' file_name = 'file.txt' # 发起 GET 请求并下载文件 response = requests.get(url) # 保存文件 with open(file_name, 'wb') as f: f.write(response.cont...

pip install requests 使用get方法下载文件 import requests def download_file(url, local_filename): response = requests.get(url, stream=True) if response.status_code == 200: with open(local_filename, 'wb') as out_file: for chunk in response.iter_content(chunk_size=1024): ...
from multiprocessing.pool import ThreadPool 我们导入了操作系统和时间模块，以检查下载文件所需的时间。模块ThreadPool 允许您使用池运行多个线程或进程。让我们创建一个简单的函数，将响应以块的形式发送到文件：def url_response(url):path, url = url r = requests.get(url, stream = True)with open(path, ...
使用Python的requests库可以简单地下载文件并保存到本地。下面是使用requests库下载文件的代码示例: import os # 创建文件保存目录 save_dir = "downloads" if not os.path.exists(save_dir): os.makedirs(save_dir) # 下载文件并保存到本地 for file_link in file_links: response = requests.get(file_link...
