bash client

This bash script implements read-access via PAIA, e.g. to check your loans. It requires a config file such as the following:

PATRON=012345678
PASSWORD=XXXXXXXX
API=https://paia.gbv.de/DE-7

Copy this script to your PATH as file paia and make it executable:

#!/bin/bash -e

hash jq 2>/dev/null || { echo >&2 "$0 requires jq to be installed!"; exit 1; }

usage() {
  echo "Usage: $0 [patron|items|fees]"
  exit $1
}

[[ -z "$1" ]] && usage

CONFIG="$HOME/.config/paia/paia.conf"
if [ -e "$CONFIG" ]; then
  . "$CONFIG"
else
  echo "Missing config file $CONFIG setting PATRON, PASSWORD and API" >&2
  exit 1
fi

login() {
  curl -s -X POST $API/auth/login \
    -d "username=$PATRON" -d "password=$PASSWORD" -d "grant_type=password" \
    -d "scope=read_patron+read_fees+read_items+read_availability" \
    | jq -er .access_token
}

if [[ "$1" == "patron" ]]; then
  URL=$API/core/$PATRON
elif [[ "$1" == "items" || "$1" == "fees" ]]; then
  URL=$API/core/$PATRON/$1
else
  usage 1
fi

TOKEN=$(login)
curl -s $URL -H "Authorization: Bearer $TOKEN" | jq .
