python使用requests下载文件

import requests
dest_name = "dest.xlsx"
dest_file_path = os.path.join(sql_file_dir, dest_name)



url = 'http://testurl/api/export_file'  # as an example
urlData = requests.post(url).content  # Get the content from the url
with open(dest_file_path, 'wb') as f:
    f.write(urlData)

注：如果输出的是xlsx文件open文件时用的模式一定要是wb的，用a的会失败
