我想让机器人在 Discord 上发送消息，但它给了我 Java JDA 中的错误

Question

我编写了代码，一开始它可以工作，但是当我输入提到机器人的命令“$info”时，它会显示下面提到的错误。请问我需要帮助

测试机器人类 这是令牌的类，这段代码可以正常工作并使机器人在线没有任何问题，但问题出在第二类

package testbot1;

import javax.security.auth.login.LoginException;

import net.dv8tion.jda.api.JDA;

import net.dv8tion.jda.api.JDABuilder;

public class Testbot1 {

    public static JDA jda;
    public static String prefix = "$";

      public static void main(String[] args) throws LoginException {

        JDA jda = JDABuilder.createDefault("The Token Here").build();
        
        jda.addEventListener(new commands());

    }
    
}

commands classThis是当我输入discord $info时应该出现的消息的类，但它给了我以下问题，并告诉我问题出在这一行

event.getChannel().sendMessage(info.build()).queue();

package testbot1;

import net.dv8tion.jda.api.EmbedBuilder;
import net.dv8tion.jda.api.events.message.guild.GuildMessageReceivedEvent;
import net.dv8tion.jda.api.hooks.ListenerAdapter;

public class commands extends ListenerAdapter {
    public void onGuildMessageReceived(GuildMessageReceivedEvent event) {
        String[] args = event.getMessage().getContentRaw().split("\\s+");
        
        if (args[0].equalsIgnoreCase(Testbot1.prefix + "info")) {
            EmbedBuilder info = new EmbedBuilder();
            info.setTitle("ElhadedyBot");
            info.setDescription("Currently, this bot is for testing only");
            info.setColor(0xf45642);
            info.setFooter("Created by Youssefeka116", event.getMember().getUser().getAvatarUrl());
            
            event.getChannel().sendTyping().queue();
            event.getChannel().sendMessage(info.build()).queue();
            info.clear();
        }
    }
}

这是我输入 Discord this command "$info" 时出现的错误

Answer 1

net.dv8tion.jda.api.exceptions.InsufficientPermissionException：由于缺少权限而无法执行操作。缺少权限：MESSAGE_EMBED_LINKS

这告诉你一切。

您尝试使用

发送嵌入消息

event.getChannel().sendMessage(info.build()).queue();

但是，机器人需要MESSAGE_EMBED_LINKS 的权限才能发送嵌入消息。

授予机器人在频道或公会中的权限。

请注意，频道权限会覆盖公会权限。
