Python 请求库的新手，得到 \'[Errno 61] Connection refused\'答案

【问题标题】：New to Python requests library, getting '[Errno 61] Connection refused'Python 请求库的新手，得到 \'[Errno 61] Connection refused\'
【发布时间】：2023-02-03 10:27:04
【问题描述】：

我到处搜索，找不到似乎适合我的用例的修复程序。我在我的 M1 mac 上遇到了一些 Python3 安装问题，但我认为它现在运行正常。

只是想学习/使用 requests library，但是当我尝试运行 this 时，非常简单的 python 代码：

import requests

response = requests.get("https://api.open-notify.org/this-api-doesnt-exist")
print(response.status_code)

我收到以下错误...

关于如何解决这个问题的任何建议？我正在拔头发。

谢谢！

【问题讨论】：

实际网站是http://api.open-notify.org/this-api-doesnt-exist，它不是https网站，而是http网站

标签： python python-3.x python-requests

【解决方案1】：

Connection Refused 表示主机 (api.open-notify.org) 没有监听您请求中的端口（https 在端口 443 上）。

我尝试连接到端口 80（纯 http），这对我有用：

>>> response = requests.get("http://api.open-notify.org/this-api-doesnt-exist")
>>> print(response.status_code)
404

为了笑，我尝试连接到基本网址

>>> response = requests.get("http://api.open-notify.org")
>>> print(response.status_code)
500
>>> response
<Response [500]>
>>> response.text
'<html>
<head><title>500 Internal Server Error</title></head>
<body bgcolor="white">
<center><h1>500 Internal Server Error</h1></center>
<hr><center>nginx/1.10.3</center>
</body>
</html>
'

太感谢了！哇，这么简单。哈哈

【解决方案2】：

抱歉，但这并不能解决此处发布的问题。

当需要特定 URL 的特定数据时，将 URL 更改为基本 URI 并不能真正起作用。在这种情况下：“http://api.open-notify.org/this-api-doesnt-exist"
