Using Nginx with OpenResty as reverse proxy to access API, making the API implement RFC 9421 HTTP Message Signatures.
The easiest way to get started with this buildpack is to check out the http sig app.
Clone the Http Sig app
$ git clone https://github.com/alux-network/heroku-openresty-http-sig.git
$ cd heroku-openresty-http-sigCreate a new Heroku app
$ heroku apps:create --stack=heroku-22 --buildpack=https://github.com/alux-network/heroku-openresty-http-sig-buildpack.gitWe have to add the heroku/python buildpack as well so that we can compile the nginx.conf template.
$ heroku buildpacks:add heroku/pythonPush the app to Heroku
$ git push heroku masterVisiting the app's URL(e.g. https://test.alux.fun) in your web browser will display "Example Domain".
curl https://test.alux.fun
Set the x-proxy-target value on the http header to the domain name(e.g. www.google.com) you want to reverse proxy.
curl -H "x-proxy-target: www.google.com" https://test.alux.fun
This buildpack has been tested with the following Heroku stacks:
heroku-22
nginx.conf and lua scripts are included in the buildpack by default. If they exist in the App, the version in the App will be used.
