The function below will allow a Mudlet user to send a message to a Discord server via a webhook.

Code: Select all

function sendToDiscordWebhook(discord_username, avatarurl, message)
  local httpdone = registerAnonymousEventHandler('sysPostHttpDone', 
    function(event, rurl, response)
      if rurl == url then display(r) else return true end
    end, true)

  local httperror = registerAnonymousEventHandler('sysPostHttpError', 
    function(event, response, rurl)
      if rurl == url then display(r) else return true end
    end, true)

  local url = ""
  local data = {
    username = discord_username, 
    avatar_url = avatarurl,
    content = message
  local header = {
    ["Content-Type"] = "application/json",
    --["Content-Length"] = data:len()
  postHTTP(yajl.to_string(data), url, header)
Place this into a script object, then insert your webhook endpoint into the url variable.

To send a message, you can do something akin to:

Code: Select all

sendToDiscordWebhook("MyBotName", false, "My boring message.")
Put this into a trigger to do fancy things like announcing kills, forwarding clan tells into your server, etc.

hey, got this working but just wanted to leave this here for anyone else who tries to get this to work-- discord wants null, not false for the avatarurl, and you can also null out the bot name on the trigger too, like so:
Code: [show] | [select all] lua
sendToDiscordWebhook(null, null, "My Boring Message")
