I'm trying to download some public data files. I screenscrape to get the links to the files, which all look something like this:
ftp://ftp.cdc.gov/pub/Health_Statistics/NCHS/nhanes/2001-2002/L28POC_B.xpt
我在 Requests 库网站上找不到任何文档.p>
I can't find any documentation on the Requests library website.
推荐答案
requests 库不支持 ftp 链接.
requests library doesn't support ftp links.
要从 FTP 服务器下载文件,您可以:
To download a file from FTP server you could:
import urllib urllib.urlretrieve('ftp://server/path/to/file', 'file') # if you need to pass credentials: # urllib.urlretrieve('ftp://username:password@server/path/to/file', 'file')
或者:
import shutil import urllib2 from contextlib import closing with closing(urllib2.urlopen('ftp://server/path/to/file')) as r: with open('file', 'wb') as f: shutil.copyfileobj(r, f)
Python3:
import shutil import urllib.request as request from contextlib import closing with closing(request.urlopen('ftp://server/path/to/file')) as r: with open('file', 'wb') as f: shutil.copyfileobj(r, f)
