response = requests.get(url) if response.status_code == 200: # 将响应的内容写入文件 with open(filename, 'wb') as file: file.write(response.content) else: print("下载失败,响应码:", response.status_code) download_file("http://example.com/file", "local_file.ext") 二、启用流式下载 ...
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'...
fileName = "1.ico" download(netPath,localPath,fileName) 去掉fileName使用网络名称 import requests def download(netPath,localPath): #分割 split = netPath.split('/') #获取最后一个元素 fileName = split[len(split)-1] r = requests.get(netPath) with open(localPath+fileName, "wb") as cod...

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: ...

通常,我们都会用 requests 库去下载,这个库用起来太方便了。 方法一 使用以下流式代码,无论下载文件的大小如何,Python 内存占用都不会增加: defdownload_file(url): local_filename = url.split('/')[-1] # 注意传入参数 stream=True withrequests.get(url, stream=True)asr: ...
在Python中,可以使用requests库来实现文件下载功能。以下是一个简单的示例: importrequestsdefdownload_file(url, save_path):response = requests.get(url)withopen(save_path,'wb')asfile: file.write(response.content)# 调用示例url ='http://example.com/file.txt'# 文件的URLsave_path ='path/to/save/...
