【问题描述】：

我有以下代码，现在它正在从任何频道抓取所有附件并将其作为嵌入发送到频道“luv”中。我希望它只从“luv”频道抓取附件并将嵌入内容也发布到“luv”中。有什么帮助吗？

  client.on("message", async (message) => {
    const channel = message.guild.channels.find(channel => channel.name === "luv");
    if (!channel) return;
    message.attachments.forEach(attachment => { // do something with the attachment // changes all attachements into embed #luv
      if (message.deletable) {
        message.delete(1000)
        const url = attachment.url;
        const aesEmbed = new RichEmbed()
        .setImage(attachment.url)

        client.channels.get("678987398838747166").send(aesEmbed);
        console.log(attachment.url);
        }
      })
    });

【解决方案1】：

您可以检查消息通道 ID 或名称。

client.on("message", async (message) => {
    if (message.channel.id !== 'PLACE CHANNEL ID HERE') return //Stop function if channel ID !== 'luv' channeld.id 
    const channel = message.guild.channels.find(channel => channel.name === "luv");
    if (!channel) return;
    message.attachments.forEach(attachment => { // do something with the attachment // changes all attachements into embed #luv
        if (message.deletable) {
            message.delete(1000)
            const url = attachment.url;
            const aesEmbed = new RichEmbed()
                .setImage(attachment.url)
            client.channels.get("678987398838747166")
                .send(aesEmbed);
            console.log(attachment.url);
        }
    })
});

而且最好不要使用find by name 方法来获取频道。

替换

const channel = message.guild.channels.find(channel => channel.name === "luv");

到

const channel = message.guild.channels.get('CHANNEL ID')
