使用 API GET 請求以及 JSON 和 Python 時收到錯誤

Question

在使用 JSON RESTful 服務和 Python3 時，嘗試執行 API 獲取請求時出現錯誤。 任何幫助表示贊賞。 我應該使用來自本網站https://nvd.nist.gov/developers/vulnerabilities#的 API 指令。 我已經有了 CVE 編號，它在下面的 URL 中列出。

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()

您的 URL 是錯誤的。 利用
