是否可以搜索特定版本的软件包何时发布？

Question

是否可以在特定包被推送到 Pypi 时进行搜索？即

pip search foo==0.17 
foo (0.17) {SOME DATE}     
pip search foo==0.18 
foo (0.18) {SOME OTHER DATE}

我可以在 Pypi 的页面上看到发布历史，但是它可以通过 pip 获得吗？我不想看到版本号，我想要它的发布日期。

是的，这是可能的。 PyPI 有一个 API 格式的所有包信息。

示例：https://pypi.org/pypi/{YOUR_PACKAGE}/json

import json
import requests


def search(package_name, version):
    url = 'https://pypi.org/pypi/%s/json' % package_name
    response = requests.request('GET', url)
    if response.ok:
        json_response = json.loads(response.content)
        uploads = json_response['releases'][version]
        for upload in uploads:
            print('upload date %s | filename = %s' % (upload['upload_time'], upload['filename']))


search('pandas', '0.24.2')

输出：
