[英]Use python Requests to download an compressed tar.gzfile and unzip it using tar
我需要使用請求調用來下載tar gz文件,我發現request.get自動解壓縮了文件,我嘗試使用此處提供的解決方案,但是當我嘗試使用tar解壓縮文件時,它說它不是gzip格式。
我嘗試了以下方法:
response = requests.get(url,auth=(user, key),stream=True)
if response.status_code == 200:
with open(target_path, 'wb') as f:
f.write(response.raw)
if response.status_code == 200:
with open(target_path, 'wb') as f:
f.write(response.raw)
raw = response.raw
with open(target_path, 'wb') as out_file:
while True:
chunk = raw.read(1024, decode_content=True)
if not chunk:
break
out_file.write(chunk)
上述所有解壓縮時都會引發錯誤:
$ tar -xvzf /tmp/file.tar.gz -C /
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
注意:不能使用urllib.open,因為我需要身份驗證等,因此我必須使用請求庫
您只需要將f.write(response.raw)
更改為f.write(response.raw.read())
試試下面的代碼,這應該為您提供正確的tar gz文件。
import requests
url = 'https://pypi.python.org/packages/source/x/xlrd/xlrd-0.9.4.tar.gz'
target_path = 'xlrd-0.9.4.tar.gz'
response = requests.get(url, stream=True)
if response.status_code == 200:
with open(target_path, 'wb') as f:
f.write(response.raw.read())
