Can't access API programmatically?

Omeka S
1

I have a new and relatively empty Omeka S installation where I can access API results in a browser window but with a python script I get “‘Connection aborted.’, RemoteDisconnected(‘Remote end closed connection without response’”

My API url: https://maevekane.net/mni-archive/api/items

My code:

import requests
import json

url = "https://maevekane.net/mni-archive/api/items"
try:
    results = requests.get(url) # make a variable that will call the url and contain the data that is requested
    results.raise_for_status() # Raise an HTTPError for bad responses (4xx or 5xx)
    data = results.json()
    print(data)
except requests.exceptions.ConnectionError as e:
    print(f"Connection error. Details: {e}")
except requests.exceptions.Timeout as e:
    print(f"Timeout Error. Details: {e}")
except requests.exceptions.RequestException as e:
    print(f"An unexpected error occurred during the request. Details: {e}")
except json.JSONDecodeError:
    print("Error: Could not decode JSON from the response. The server might have returned non-JSON data or an empty response.")

I can get other Omeka API results (eg, https://wardepartmentpapers.org/api/items) just fine with this code so I think it must be something with my own Omeka installation? The items are all public so I don’t think it’s an authentication issue.

Hi, maybe you could try to add headers to your request so it does not get rejected? There are plenty of examples over the web.

Try this:

import requests
import json

url = "https://maevekane.net/mni-archive/api/items"

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"
}

try:
    results = requests.get(url, headers=headers, timeout=30)
    results.raise_for_status()
    data = results.json()
    print(data)
except requests.exceptions.ConnectionError as e:
    print(f"Connection error. Details: {e}")
except requests.exceptions.Timeout as e:
    print(f"Timeout Error. Details: {e}")
except requests.exceptions.RequestException as e:
    print(f"An unexpected error occurred during the request. Details: {e}")
except json.JSONDecodeError:
    print("Error: Could not decode JSON from the response.")

If that still doesn’t help, the issue may be related to TLS/SSL and how your Python environment handles the server certificate. You can test this hypothesis by temporarily adding verify=False to your requests.get() call (not for production, but for diagnostic purposes only).If setting verify=False resolves the issue, the actual cause is likely the SSL certificate chain, and the solution would be to update the certifi package (pip install --upgrade certifi) or install the certificate package for your operating system.

It was the lack of headers, thank you both. I was able to access other omeka sites without headers so didn’t know I’d need them for my own install.
