Sending text file attachment using JSON

[ilium007]

❓ Question
Is sending attachments using JSON supported? I want to send a text file (log file) using the JSON POST method. I have tried base64 encoding the file but can't get it to work.

I can send attachments using curl POST URL string in a shell scrip as a testt:

send_alert () {
  /usr/bin/curl -X POST \
    -F "title=$1" \
    -F "body=$2" \
    -F "attach=@$LOG_FILE" \
    $APPRISE_URL
}

Can this be done by sending a JSON string instead?
