Discord Bot

May 25, 2016

I had a bunch of problems getting a discord bot going. Here’s what I did:

Registered an app and set up a bot user.
Sign into the gateway (only required once, but it won’t let your bot send messages otherwise). I ran this JS snippet in the console of Chrome:

var ws = new WebSocket('wss://gateway.discord.gg');

mystring = JSON.stringify({
 "op": 2,
 "d": {
 "token": "<bot token>",
 "properties": {
 "$os": "linux",
 "$browser": "sometestingbrowser",
 "$device": "sometestingdevice",
 "$referrer": "",
 "$referring_domain": "",
 },
 "compress": true,
 "large_threshold": 250,
 } 
})

ws.send(mystring)

POSTed to the API server:

discord_body='this is my variabled message'
echo "{\"content\":\"$discord_body\"}" | curl -v -H "Authorization: MTgzOTY1MDU1NDQ2OTQxNjk4.CiNoWw.WnZ_PiKSWVg5Nrq4JlVud37j76Q" -H "User-Agent: myBotThing (https://scooterx3.net, v0.1)" -H "Content-Type: application/json" -X POST --data-binary "@-" https://discordapp.com/api/channels/175975476253163521/messages

And that pretty much wraps it up. Not a hugely awesome bunch of documentation but it’ll trigger my brain if I need it in the future.

Edit Oct 30, 2017:

Cleaned up the format. Also a note: I acknowledge that I did paste the actual authorization token above, but it’s invalid now. Don’t be like me; keep your tokens/keys secret.
