如何在discord.js中向指定频道发送带按钮的Embed消息？

问题描述 #

尝试向指定频道（ID：1068005047373414481）发送带有ActionRow按钮组件的Embed消息，该频道并非交互触发的频道。使用 interaction.guild.channels.cache.get(id).send(embed); 方法发送时失败，始终抛出 DiscordAPIError[50006]: Cannot send an empty message 错误，同时不确定能否像 interaction.reply({ embeds: embed, components: [row] }); 那样为消息添加组件。

测试代码 #

client.once('ready', () => {
    console.log('Ready!')
    client.user.setActivity("all you rascals", {
        type: ActivityType.Watching,
    });
    var testing = new EmbedBuilder()
    .setTitle('test')

    client.guilds.cache.get(guild).channels.cache.get(channel).send(testing)
})

错误原因 #

Discord.js v14及以上版本中，TextChannel.send() 方法要求传入配置对象，而非直接传入Embed实例。测试代码中直接传Embed导致API请求的 embeds 字段为 undefined，被判定为“空消息”。

修复方案 #

1. 修正Embed发送格式 #

将 send(testing) 改为 send({ embeds: [testing] })，同时确保 guild 和 channel 变量替换为实际的服务器ID和频道ID：

client.once('ready', () => {
    console.log('Ready!')
    client.user.setActivity("all you rascals", {
        type: ActivityType.Watching,
    });
    const testing = new EmbedBuilder()
        .setTitle('test')
    
    // 替换为实际的服务器ID和频道ID
    const targetChannel = client.guilds.cache.get('你的服务器ID').channels.cache.get('1068005047373414481');
    targetChannel.send({ embeds: [testing] });
})

2. 添加ActionRow组件 #

完全可以像 interaction.reply 一样给消息添加组件，只需在配置对象中加入 components 字段，示例如下：

client.once('ready', () => {
    console.log('Ready!')
    client.user.setActivity("all you rascals", {
        type: ActivityType.Watching,
    });
    const testing = new EmbedBuilder()
        .setTitle('test');
    
    // 创建ActionRow和按钮
    const testButton = new ButtonBuilder()
        .setLabel('测试按钮')
        .setStyle(ButtonStyle.Primary)
        .setCustomId('test_button');
    
    const row = new ActionRowBuilder().addComponents(testButton);
    
    const targetChannel = client.guilds.cache.get('你的服务器ID').channels.cache.get('1068005047373414481');
    targetChannel.send({ 
        embeds: [testing],
        components: [row] 
    });
})

注意事项 #

• 确保机器人拥有目标频道的发送消息和嵌入链接权限
• 若使用缓存获取频道失败，可改用 client.channels.fetch('频道ID') 方法（缓存可能未加载目标频道）
