这篇文章主要介绍python如何递归下载文件夹下所有文件，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
最近想备份网站，但是php下载文件的大小是有大小限制的，而我也懒得装ftp再下载了，就想着暂时弄个二级域名站，然后用python(python3)的requests库直接下载网站根目录下的所有文件以及文件夹。（0-0就是这么任性）
1.安装requests库
pip install requests
2.下载文件夹下所有文件及文件夹
这里需要处理的地方主要是文件夹，这里我们判断出该链接是文件夹时，自动创建文件夹，并递归继续进行操作，否则判断该链接是文件，直接使用requests get方法下载，话不多说，看代码

import requests
import re
import os
import sys
def help(script):
text = 'python3 %s https://www.bobobk.com ./' % script
print(text)
def get_file(url,path):##文件下载函数
content = requests.get(url)
print("write %s in %s" % (url,path))
filew = open(path+url.split("/")[-1],'wb')
for chunk in content.iter_content(chunk_size=512 * 1024):
if chunk: # filter out keep-alive new chunks
filew.write(chunk)
filew.close()
def get_dir(url,path): #文件夹处理逻辑
content = requests.get(url).text
if "Index of" in content:
sub_url = re.findall('href="(.*?)" rel="external nofollow" ',content)
print(sub_url)
for i in sub_url:
if "/" in i:
i = i.split("/")[0]
print(i)
if i!="." and i!="..":
if not os.direxists(path+i):
os.mkdir(path+i)
get_dir(url+"/"+i,path+i+"/")
print("url:"+url+"/"+i+"\nurl_path:"+path+i+"/")
else:
get_file(url+"/"+i,path)
else:
get_file(url,path)
if __name__ == '__main__':
if not sys.argv[1]:
help(sys.argv[0])
exit(0)
else:
get_dir(sys.argv[1],"./")</pre><p>至此，就在本地目录完全还原下载原网站的路径和文件了。</p><p>以上是“python如何递归下载文件夹下所有文件”这篇文章的所有内容，感谢各位的阅读！希望分享的内容对大家有帮助，更多相关知识，欢迎关注创新互联行业资讯频道！</p> <br>
