ditto-client 0.4.0

Eclipse Ditto Python Client

Eclipse Ditto Client

Eclipse Ditto Project - https://eclipse.dev/ditto/index.html

This repository is the python client generated using Microsoft Kiota (https://github.com/microsoft/kiota-python) and a CLI based client.

Install

uv add ditto-client

Running Ditto

There are 3 modes in which you can run Eclipse Ditto from this repository

Mode 1

A docker compose that has nginx as a reverse proxy and configured to do Basic Authentication.

# to start nginx reverse proxy based setup (that uses Basic Authentication)
uv run poe compose-ba-up

# to stop nginx reverse proxy based setup
uv run poe compose-ba-down

Mode 2

A docker compose that exposes the Eclipse Ditto Gateway at port 8081 and sets ENABLE_PRE_AUTHENTICATION=true

In this mode, the client application directly talks to the gateway and sets the header

# to start with out nginx and pre-auth setup
uv run poe compose-pre-up

# to stop
uv run poe compose-pre-down

Mode 3

A docker compose that exposes the Eclipse Ditto Gateway at port 8081 and sets ENABLE_PRE_AUTHENTICATION=false and requires JWT based authentication

In this mode, the client application first gets the JWT token from the issuer and then pass it to the gateway

Look at assets/ditto/ditto-gateway-jwt.yml to learn about the settings (A mock oauth server is included)

# to start with out nginx and pre-auth setup
uv run poe compose-jwt-up

# to stop
uv run poe compose-jwt-down

Usage - API

Basic Authentication

auth_provider = BasicAuthProvider(user_name=_USERNAME, password=_PASSWORD)

request_adapter = HttpxRequestAdapter(auth_provider)
request_adapter.base_url = "http://host.docker.internal:8080"

ditto_client = DittoClient(request_adapter)

response = await ditto_client.api.two.things.get()

Default setup for Ditto uses Ngix with basic authentication. A custom authentication provider has been included in the library to support it. See BasicAuth Provider.

See examples/basic.py for the full usage

Pre Authentication

auth_provider = PreAuthProvider(auth_subject="ditto:ditto")

request_adapter = HttpxRequestAdapter(auth_provider)
# Note the port is that of gateway
request_adapter.base_url = "http://host.docker.internal:8081"

ditto_client = DittoClient(request_adapter)

response = await ditto_client.api.two.things.get()

A custom authentication provider has been included. See PreAuth Provider.

See examples/pre.py for the full usage

JWT Authentication

auth_provider = JWTAuthProvider(token=<your_token>")

request_adapter = HttpxRequestAdapter(auth_provider)
# Note the port is that of gateway
request_adapter.base_url = "http://host.docker.internal:8081"

ditto_client = DittoClient(request_adapter)

response = await ditto_client.api.two.things.get()

A custom authentication provider has been included. See JWTAuth Provider.

See examples/jwt.py for the full usage

Usage - CLI

The Ditto client includes a comprehensive CLI for interacting with Eclipse Ditto services. The CLI provides the following commands:
