Discord SDK download returns 403 #22

Closed DeDiamondPro closed 3 years ago

DeDiamondPro commented 3 years ago

Hi, I just started using this but quite quickly ran in to an issue, when I try to download the SDK from the discord servers it returns a 403, So I was wondering if I'm doing something wrong, there is a problem with the libary or there is a problem with discord.

I'm just using the example code for dowloading the SDK.

This is caused by Discord (or Cloudflare) trying to block automated requests. They seem to block the User-Agent sent by some Java versions, but allow some others.

You could try to set the User-Agent to a common value (e.g. a Firefox version) to avoid this problem.

URL downloadUrl = new URL("https://dl-game-sdk.discordapp.net/2.5.6/discord_game_sdk.zip");

URLConnection connection = downloadUrl.openConnection();
connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");

ZipInputStream zin = new ZipInputStream(connection.getInputStream());

(see https://github.com/JnCrMx/MinecraftDiscordLobbies/blob/1.16.4/src/main/java/com/github/JnCrMx/discordlobbies/DiscordLobbiesMod.java#L60 for an example)
