Question

我有一个网址，我可以针对

发出curl请求

curl --insecure --header "Expect:" \ 
     --header "Authorization: Bearer <api key>" \
     https://some-url --silent --show-error --fail -o data-package.tar -v

我在这里尝试使用请求模块

r = requests.get('https://stg-app.conduce.com/conduce/api/v1/admin/export/' + id, 
                 headers=headers)
r.content ##binary tar file info

如何将其写入类似tarfile的数据包？

Answer 1

content将是您可以写出的整个文件（以字节为单位）。

import requests

r = requests.get('...YOUR URL...')

# Create a file to write to in binary mode and just write out
# the entire contents at once.
# Also check to see if we get a successful response (add whatever codes
# are necessary if this endpoint will return something other than 200 for success)
if r.status_code in (200,):
    with open('tarfile.tar', 'wb') as tarfile:
        tarfile.write(r.content)

如果您正在下载任意tar文件并且它可能相当大，您可以choose to stream it代替。

import requests

tar_url = 'YOUR TAR URL HERE'
rsp = requests.get(tar_url, stream=True)
if rsp.status_code in (200,):
    with open('tarfile.tar', 'wb') as tarfile:
        # chunk size is how many bytes to read at a time,
        # feel free to adjust up or down as you see fit.
        for file_chunk in rsp.iter_content(chunk_size=512):
            tarfile.write(chunk)

请注意，此模式（使用wb模式打开文件）通常应该与编写任何类型的二进制文件一起使用。我建议阅读writing file documentation for Python 3（Python 2 documentation here）。

如何直接将内容写入tar文件？
