discord.js如何为发送的MessageEmbed嵌入消息添加表情反应

discord.js中频道发送消息的send()方法是异步方法，执行完成后会返回已发送的消息对象实例，你只需要拿到反馈频道里发送的Embed消息实例，调用实例上的react()方法即可添加表情反应，和你给触发命令的原消息加反应的逻辑完全一致。

具体改动点 #

• 给collector.on("end")的回调函数添加async标记，支持内部使用await等待异步操作
• 给appsChannel.send()前添加await关键字，等待Embed消息发送完成，拿到返回的反馈消息对象实例
• 对拿到的反馈消息对象依次调用react('👍')、react('👎')添加目标表情
• 给所有react()操作补充空错误捕获，避免机器人缺少频道添加反应权限、原消息被删除等场景抛出未处理的Promise错误，导致命令崩溃
• 顺手修正了原代码注释中@parom的拼写错误，替换为JSDoc标准的@param标记

修改后完整代码 #

const { Client, Message, MessageEmbed, Intents } = require("discord.js");

module.exports = {
    name: "sbfeedback",
    /**
    * @param {Client} client
    * @param {Message} message
    * @param {String[]} args
    */
     async execute(client, message, args) {
        const questions = [
            "What feedback would you like to give?",
            "Anything else you would like to add?"
        ];
          
        let collectCounter = 0;
        let endCounter = 0;
         
        const filter = (m) => m.author.id === message.author.id;
        
        const appStart = await message.author.send(questions[collectCounter++]);
        const channel = appStart.channel;
        
        const collector = channel.createMessageCollector(filter);
        message.delete({timeout: 100})

        collector.on("collect", () => {
            if (collectCounter < questions.length) {
                channel.send(questions[collectCounter++]);
            } else {
                channel.send("Thank you for your feedback! If you would like to suggest anything else please do so with `-sbfeedback`.");
                collector.stop("fulfilled");
            }
        });

        const appsChannel = client.channels.cache.get("886099865094983691");
        collector.on("end", async (collected, reason) =>{
            if (reason === "fulfilled") {
                let index = 1;
                const mappedResponses = collected
                    .map((msg) => { 
                        return `${index++}) ${questions[endCounter++]}\n-> ${msg.content}`;
                    })
                    .join("\n\n");
                        
                // 拿到发送到反馈频道的Embed消息实例
                const feedbackMsg = await appsChannel.send(
                    new MessageEmbed()
                        .setAuthor(message.author.tag, message.author.displayAvatarURL({ dynamic: true}))
                        .setTitle("!")
                        .setDescription(mappedResponses)
                        .setColor(`RANDOM`)
                        .setTimestamp()
               
                );
                // 给原触发消息加反应
                message.react('👍').then(() => message.react('👎')).catch(() => {});
                // 给反馈频道的Embed消息加对应反应
                feedbackMsg.react('👍').then(() => feedbackMsg.react('👎')).catch(() => {});
            }
        });
    },
};
