通过 Java Discord Api 发送直接消息

Question

I want the bot to send a direct message but for the love of god,I cannot find the exact methods/functions to do so.All that is available is to send a message to the same server's channel

   event.getChannel().sendMessage("hello").queue();

I want the message to sent directly to the user or rather that a particular user gets the message. please help!

You never have to guess at how to use a library - that's what documentation is for. Any library worth its salt has documentation listing every single class, method, and property you need to worry about.

A quick google search for "discord-jda docs" takes us to the javadoc: https://ci.dv8tion.net/job/JDA/javadoc/index.html

You want to send a message to a user, right? So let's use the search bar and find User . First result under Types is net.dv8tion.jda.api.entities.User . We're now at https://ci.dv8tion.net/job/JDA/javadoc/net/dv8tion/jda/api/entities/User.html

If you want to know how to do something with a user , we look at the Methods every User has. Two catch my eye right away: User.hasPrivateChannel() and User.openPrivateChannel() . We'll click the second one since it looks relevant.

Lo and behold, the docs have example usage! I'll quote it below:

 // Send message without response handling public void sendMessage(User user, String content) { user.openPrivateChannel() .flatMap(channel -> channel.sendMessage(content)) .queue(); }

This seems pretty straightforward. So the basic usage you're looking for (assuming event is a MessageReceivedEvent ) is this:

event.getAuthor().openPrivateChannel().flatMap(channel -> channel.sendMessage("hello")).queue();
