尝试在 Python 中为 API 'requests.get' 的许多错误

【中文标题】尝试在 Python 中为 API \'requests.get\' 的许多错误

【英文标题】：Many errors trying to 'requests.get' for an API in Python尝试在 Python 中为 API 'requests.get' 的许多错误

【问题描述】：

我正在尝试学习使用 python 访问 API。 我什至都在努力克服第一道障碍。

按照我放的教程：

import requests

response = requests.get("https://api.open-notify.org/astros.json")

print(response.status_code)

使用了开放通知 api，因为它非常简单，有利于学习。

运行脚本后，我得到的只是本文底部显示的错误消息。

我发帖是希望有人以前遇到过这个问题并且知道解决方案，或者有人只是知道解决方案。

任何指导将不胜感激！

谢谢。

【问题讨论】：

有趣的是，我在本地得到这个：requests.exceptions.SSLError: HTTPSConnectionPool(host='api.open-notify.org', port=443): Max retries exceeded with url: /astros.json (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1122)')))

【参考方案1】：

https://api.open-notify.org/astros.json 在您的浏览器中给出了类似的错误。问题是它不支持HTTPS。 http://api.open-notify.org/astros.json 有效。

这里有个问题：https://github.com/open-notify/Open-Notify-API/issues/9

【讨论】：

就我个人而言，我觉得这很多不太安全。任何 API 都应该强制使用 HTTPS
