Python: download a report from SQL Server Reporting Services with requests

Question

I’m trying to get a report from SQL Server Reporting Services with the py package requests, but I’m getting the 401 error. If I access the SQL server via web, there is a pop-up asking me for user/pwd, I guess I’m failing to replicate this step via Python code.

These don’t work:

url = "report-url"

requests.get(url, auth=(usr,pwd))

session = requests.Session() 
session.auth = (usr,pwd)
session.get(url)

Answer 1

There’s a related thread on Microsoft Q&A discussing accessing SSRS reports over the network
Here’s another ref about SSRS URL access
Since your sample code only implemented basic auth with the HTTP GET method I highly recommend reading the above threads cause it might be a problem related to the environment.
If you want to take care of the pop-up, you can ref this answer about implementing a headless browser or WebKit

SSRS uses NTML auth method. By default SSRS does not allow username and password.

This code snippet include the library required.

import os
import requests
from requests_ntlm import HttpNtlmAuth

# Variables
username = os.environ.get("USERNAME")
password = os.environ.get("PASSWORD")
domain = os.environ.get("DOMAIN")
cert_path = os.environ.get("CERT_PATH")

# Create a session with NTLM authentication
session = requests.Session()
session.auth = HttpNtlmAuth(f'{domain}\{username}', password)
session.verify = cert_path #if you have HTTPS
