config.py Breakdown

Centralized configuration loader for API endpoints and authorization headers. Pulls values from .env and defines fallbacks for local use.

1. Load .env File

from dotenv import load_dotenv
load_dotenv()

Purpose	Loads environment variables from a .env file into Python
Fallback	Defaults are used if the .env file or variables are missing

2. Ollama API Configuration

OLLAMA_URL = os.getenv("OLLAMA_URL", "http://localhost:11434").rstrip("/")
OLLAMA_EMBEDDING_URL = os.getenv("OLLAMA_EMBEDDING_URL", f"{OLLAMA_URL}/api/embeddings")

Variable	Description	Default
OLLAMA_URL	Base URL for Ollama API	http://localhost:11434
OLLAMA_EMBEDDING_URL	Embedding endpoint	${OLLAMA_URL}/api/embeddings

rstrip("/") ensures no double slashes in concatenated URLs.

3. Open WebUI API Configuration

OPEN_WEBUI_URL = os.getenv("OPEN_WEBUI_URL", "http://localhost:3000").rstrip("/")
OPEN_WEBUI_TOKEN = os.getenv("OPEN_WEBUI_TOKEN", "Bearer YOUR_OPEN_WEBUI_TOKEN")

Variable	Description	Default
OPEN_WEBUI_URL	Base URL for Open WebUI	http://localhost:3000
OPEN_WEBUI_TOKEN	Bearer token for API authentication	Placeholder token

4. HTTP Headers

HEADERS = {
    "Authorization": OPEN_WEBUI_TOKEN,
    "Content-Type": "application/json"
}

Key	Value
Authorization	Bearer token pulled from .env
Content-Type	JSON encoding for API payloads

Used by functions that interact with Open WebUI such as:

query_open_webui()
upload_file_to_knowledge()

.env Example

# Ollama configuration
OLLAMA_URL=http://localhost:11434
OLLAMA_EMBEDDING_URL=http://localhost:11434/api/embeddings

# Open WebUI configuration
OPEN_WEBUI_URL=http://localhost:3000
OPEN_WEBUI_TOKEN=Bearer sk-abc123xyz
