使用 JSON RESTful 服務和 Python3 時，我在嘗試執行 API 獲取請求時遇到錯誤。任何幫助表示贊賞。我應該使用本網站https://nvd.nist.gov/developers/vulnerabilities# 的API 說明。我已經有了 CVE 編號，它列在我下面的 URL 中。
import requests
import json
response = requests.get('https://services.nvd.nist.gov/rest/json/CVE-2021-40463/1.0/').json()
print (response)
File "/Users/xxxx/Desktop/UT_Code/UT_Homework.py", line 4, in <module>
response = requests.get('https://services.nvd.nist.gov/rest/json/CVE-2021-40463/1.0/').json()
File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/requests/models.py", line 910, in json
return complexjson.loads(self.text, **kwargs)
