Found myself in need to send an arbitrary text with unicode and quotes, the original example didn't work.
Here is updated one, forcing jq to do all of the string escaping:
#!/usr/bin/env bash
# noti-bot - send notification in telegram
# Usage:
# echo "your text" | noti-bot
# or
# noti-bot "your text" | noti-bot
API=yours
chat_id=yours
if [[ -n "$1" ]]; then
msg="$1"
else
msg="$(cat)"
fi
# to escape " and unicode, no, printf is not enough, neither is multiple -d for curl
data="$(echo '{"chat_id": "aaa", "text": "aaa", "disable_notification": false}' |
jq --arg msg "$msg" --arg chat "$chat_id" '{"chat_id": $ARGS.named.chat, "text": $ARGS.named.msg, "disable_notification": false}')"
# echo "$data"
ans="$(curl -s --tlsv1.2 -X POST \
-H 'Content-Type: application/json' \
-d "$data" \
https://api.telegram.org/bot$API/sendMessage)"
if [[ "$(echo "$ans" | jq -r '.ok')" != "true" ]]; then
echo "$ans" | jq -r '"error \(.error_code) - \(.description)"'
fi
Demo:
echo -e 'Nope!";$(pwd)"\nyes - приветこんにちは' | ./noti-bot
I know, I know, "at this point just use python or something". I needed it with curl.
If succesful - prints nothing.
If not - prints "error_code - error_description".
