LINE Bot Router

This application can accept LINE Bot webhook HTTP requests, check signature and reroute request to other bot servers.

Each downstream bot will receive each message, but only one can use reply API. Though any bot can use push APIs.

2. Make sure all downstream bot use the same channel-secret and channel-access-token.

3. Add all downstream bot webhooks URIs to the downstreams list in in application.yml.

4. In LINE Developers Console set Webhook URL to the https://your-host.com/webhook/bot.

5. Build ./gradlew build.

6. Run java $JAVA_OPTS -jar router-server/build/libs/router-server.jar --armeria.ports\[0\].port=8080 --armeria.ports\[0\].protocol=HTTP.

Rate limits for replies, push messages and other APIs are shared between all bots.
