New to Python requests library, getting '[Errno 61] Connection refused'-CodePudding

I've searched high and low and can't find a fix that seems to fit my use case. I've had some Python3 install issues on my M1 mac but think it's now running okay.

Just trying to learn / work with the requests library, but when I try to run this very simple python code:

import requests

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

I get the below error...

Any advice on how to fix this? I'm pulling my hair out.

Thank you!

CodePudding user response：

Connection Refused means that the host (api.open-notify.org) is not listening on the port (https is on port 443) in your request.

I tried connecting to port 80 (plain http) instead and that worked for me:

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

For laughs, I tried connecting to the base url

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