使用 JSON 和 Python 的 API GET 请求时收到错误

Question

在使用 JSON RESTful 服务和 Python3 时，我在尝试执行 API 获取请求时遇到错误。任何帮助表示赞赏。我应该使用来自这个网站https://nvd.nist.gov/developers/vulnerabilities# 的 API 说明。我已经有了 CVE 编号，它列在下面我的 URL 中。

import requests
import json

response = requests.get('https://services.nvd.nist.gov/rest/json/CVE-2021-40463/1.0/').json()

print (response)

    response = requests.get('https://services.nvd.nist.gov/rest/json/CVE-2021-40463/1.0/').json()
