FCC National Broadband Map API 连接故障求助

问题背景

我排查FCC国家宽带地图API的连接问题已有多时，判断BDC Public Data API Specifications中列出的端点已不可用、故障或下线——调用该端点时完全收不到任何响应（无论成功还是失败）。

测试代码及现象

我使用Python的requests库发起GET请求，代码如下：

import requests

# API Base URL
base_url = "https://broadbandmap.fcc.gov/api/public/map"

# User Credentials
username = "username@domain.com"
with open("token.txt", "r") as file:  # token.txt 存储从FCC网站获取的hash_value
    hash_value = file.read().strip()

# 3.1 获取"As Of Dates"列表
list_as_of_dates_url = f"{base_url}/listAsOfDates"
print(list_as_of_dates_url)
list_as_of_dates_headers = {"username": username, "hash_value": hash_value}
print("Making GET request to provided URL")
list_as_of_dates_response = requests.get(list_as_of_dates_url, headers=list_as_of_dates_headers)
print("GET Request complete.")
print('3.1 View List of "As Of Dates" Response: ', list_as_of_dates_response.json())

运行脚本后，请求会无限挂起，永远无法打印出“GET Request complete”。

浏览器测试的错误信息

我将list_as_of_dates_url粘贴到浏览器地址栏，手动在请求头中添加username和hash_value键值对，收到以下CSP相关错误：

“Refused to connect to 'https://broadbandmap.fcc.gov/api/public/map/listAsOfDates' because it violates the following Content Security Policy directive: "default-src 'none'". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.”
“Refused to connect to 'https://broadbandmap.fcc.gov/api/public/map/listAsOfDates' because it violates the document's Content Security Policy.”

但API规范中从未提及需要设置connect-src。
