Mudlet Discord Webhook Support

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")

Hi xmods, I'm having trouble with this... I have the Webhooks/integration properly, but it looks like each of the aliases is not functioning as expected.. I am able to use dmsg to send with fixing a period in the payload, but no matter what I try for auction/group I just see a blank line sent to discord.

For what its worth, the default dmsg function sends

Code: Select all

content  = ".\n \n"..msg
which just generates a period, a blank line, and then the message.

Any ideas?

Make suer & check that you aren't blocking embeds with settings?
local user, server, and channel all may have a setting for that.

The dmsg alias was set that way to make it easier to read,
if you want to change the dmsg alias, .. just set it to..

content = msg
