Python3实现requests请求下载url文件到指定目录

python2 实现参考：blog.csdn/tankpanv/article/details/100731081

python3版本

def urldownload(url,filename=None): """ 下载文件到指定目录 :param url: 文件下载的url :param filename: 要存放的目录及文件名，例如：./test.xls :return: """ down_res = requests.get(url) with open(filename,'wb') as file: file.write(down_res.content)

判断下载文件是否存在

import os def test_download(): url = self.download() Common.urldownload(url,filename='./test.xls') # path = pathlib.Path('./test.xls') #方法一 path = './test.xls' assert os.path.exists(path)==True #方法二 os.remove(path)
