Alexa Authentication Server

This is a small web server that belongs to the https://github.com/MrBuddyCasino/ESP32_Alexa project and handles authentication.

Required Software

Current version of Rust, ideally installed using rustup, and Cargo.

• rustup self update
• rustup update

Build

Execute cargo build --release. The binary will be at target/release/alexa-auth.

Run

You need to provide the following environment variables:

• client_id
• client_secret
• redirect_uri

If they are missing, the program will exit with an error. I run it as a service on Ubuntu behind nginx, this is my SystemD unit file:

[Unit]

Environment=client_id=amzn1.application-oa2-client.xxxxxxxxxxxxxxxxxx
Environment=client_secret=xxxxxxxxxxxxxxxxx

ExecStart=/home/michaelboeckling/alexa-auth/target/release/alexa-auth

I did not manage to cross-compile it from my Mac due to OpenSSL.
