Simple echo provider+consumer using Arrowhead Framework

This repository contains simple echo provider and consumer as an example for using Arrowhead Framework.

It is designed to use testcloud2 configuration from the core-java-spring repository. Therefore, it should be much easier to test this locally, as all required certificates are already created.

The reason for using testcloud2 instead of testcloud1 is, that the latter one had some naming issues inside the certificates.

In addition, because of #202 underscores are not supported in Arrowhead Framework 4.4.0+ (not supported in DNS/CN). To avoid issues we won't use even dashes, because who knows.

Downloading required packages

This version requires Python 3 with only one additional package:

python3 -m pip install requests-pkcs12

Setting up the certificates

TODO: Use already generated certificates to make this even easier.

At first, you have to download the CertificateGeneration submodule. Note: If you are familiar with different way for generating the certificates, feel free to use it instead.

git submodule update --init ./CertificateGeneration

Obtain master certificates

wget -O ./CertificateGeneration/master.crt https://raw.githubusercontent.com/eclipse-arrowhead/core-java-spring/master/certificates/master.crt
wget -O ./CertificateGeneration/master.p12 https://raw.githubusercontent.com/eclipse-arrowhead/core-java-spring/master/certificates/master.p12

Obtain testcloud2 certificates

mkdir ./certificates
wget -O ./certificates/testcloud2.crt https://raw.githubusercontent.com/eclipse-arrowhead/core-java-spring/master/certificates/testcloud2/testcloud2.crt
wget -O ./certificates/testcloud2.p12 https://raw.githubusercontent.com/eclipse-arrowhead/core-java-spring/master/certificates/testcloud2/testcloud2.p12

Generate certificates for echo service

PASSWORD=123456 FOLDER="../certificates/" DOMAIN="aitia" CLOUD="testcloud2" bash ./CertificateGeneration/generate.sh echoserver echoclient

Setting up the rules (and services, etc.)

To set up all required data in the Arrowhead database, at first run:

python3 echo-setup.py

Alternatively, you can launch both parts of the service and receive:

Interface ID: %d
Provider ID: %d
Service ID: %d
Consumer ID: %d

And use echo-auth.py to add an intracloud authorization rule to the Arrowhead database:

python3 echo-auth.py -i %d -p %d -s %d -c %d

This has to be run only one (on subsequent runs it does nothing). Then, proceed with relaunching the echo-client.

Launching the service

In two separate terminals run both:

python3 echo-server.py

python3 echo-client.py
