Discord机器人创建

Discord 机器人对接

环境搭建

详情可见：https://blog.csdn.net/weixin_43718648/article/details/109956026

代码参考

这里使用的是github上大神进行封装的SDK

详情可见： https://github.com/Javacord/Javacord

启动配置：

package com.example.demo.util;

import jodd.util.StringUtil;
import org.javacord.api.DiscordApi;
import org.javacord.api.DiscordApiBuilder;
import org.javacord.api.entity.channel.TextChannel;
import org.javacord.api.entity.message.MessageAuthor;
import org.javacord.api.entity.message.MessageBuilder;
import org.javacord.api.entity.message.embed.EmbedBuilder;
import org.javacord.api.event.connection.LostConnectionEvent;
import org.javacord.api.listener.connection.LostConnectionListener;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.util.CollectionUtils;

import java.util.Collection;
import java.util.Objects;

/**

 */
@Configuration
public class DiscordTest {


    @Bean
    public DiscordApi restart() {
        // Insert your bot's token here
        String token = "O";
        DiscordApi api = newDiscordApiBuilder().setToken(token).login().join();
        //开始活动
        api.addMessageCreateListener(event -> {
            if (event.getMessageContent().equalsIgnoreCase("/ooxx")) {
            }
        });


        //服务器断联listener
        api.addLostConnectionListener(new LostConnectionListener() {
            @Override
            public void onLostConnection(LostConnectionEvent event) {
                // TODO Auto-generated method stub
            }
        });
        // Print the invite url of your bot
        System.out.println("You can invite the bot by using the following url: " + api.createBotInvite());
        return api;
    }
}

这里启动之后，控制台就会打印出一个连接，用浏览器打开，就能邀请机器人加入服务器。
