Kleo is a Bluetooth-enabled electronic attendance system that is designed to cope with the problems of managing attendance lists of students.
Kleo provides REST API for Android and Web applications. The REST API is defined with OpenAPI2 (Swagger) and availale on Swaggerhub. The Postman collection is also provided.
In order to run the app, the following environment variables must be set:
# Common
ETHEREUM_INFURA - an Infura endpoint to Ethereum net (e.g https://mainnet.infura.io/your_token)
ETHEREUM_ATTENDANCE_TRACKER_ADDRESS - an address of the deployed attendance_tracker.sol smart contract
# Backend specific
ETHEREUM_WALLET_PASSWORD - a password for your wallet used to post attendances to the blockchain
ETHEREUM_WALLET_FILE - a path to your wallet file used to post attendances to the blockchain
# Android specific
ETHEREUM_ATTENDANCE_TRACKER_URL - a url of the contract on the public blockchain explorer web
An example .bash_profile may look like:
export ETHEREUM_INFURA="https://ropsten.infura.io/NoXjb7h7L0YPzNSbroLJ"
export ETHEREUM_WALLET_PASSWORD="extremepassword"
export ETHEREUM_WALLET_FILE="~/UTC--2018-01-11T18-58-12.059Z--0121a28a3a04a71bd11f4749ca23f2585b4844d5"
export ETHEREUM_ATTENDANCE_TRACKER_ADDRESS = "0x324f85e86b1c42f24894c31aef1d74360ef8607e"
export ETHEREUM_ATTENDANCE_TRACKER_URL="https://ropsten.etherscan.io/address/0x324f85e86b1c42f24894c31aef1d74360ef8607e"
The backend default profile is DEV, populated with test data: groups and user accounts. To run the backend, execute:
$ ./gradlew bootRun
This will run the backend on http://localhost:8080/api with DEV profile activated.
The DEV profile is populated with the following user you may use for development:
| Username | Password | Roles | Configurable In |
|---|---|---|---|
| superuser@tum.de | password | SUPERUSER, STUDENT, TUTOR | data.sql |
| student@tum.de | password | STUDENT | data.sql |
| tutor@tum.de | password | TUTOR | data.sql |
You still can use any valid student or staff TUM Shibboleth account.
To run the android client application run:
$ ./gradlew :android:installDevDebug
This will build the APK and immediately install it on a running emulator or connected device. The backend API client in the app will point to local IP of the machine used to build the apk.
