Discord.js：按ID获取消息提供错误的输出

Question

当我从另一个用户那里得到帮助时，我通过id尝试了一个fetchMessage（）。我猜想出了点问题，因为当我输入我的报告命令的ID时，它返回[object Promise]而不是ID对应的消息。这是一个代码位及其输出内容：

if (cmd === `${prefix}report`) {
    let messageID = args[0];
    if (isNaN(messageID)) {
        message.author.send("Not an ID")
        return;
    }
    let messagea = message.channel.fetchMessages(messageID);
    let reportEmbed = new Discord.RichEmbed()
        .setTitle("Reports")
        .setColor("#F7E533")
        .addField("Message", messagea)
        .addField("Reported User", `@${messagea.author}`)
        .addField("Reported By", `${message.author} with ID: ${message.author.id}`)
        .addField("Time", message.createdAt)
    let reportschannel = message.guild.channels.find(`name`, botconfig.reportsChannel);
    if (!reportschannel) return message.channel.send("Couldn't find reports channel.");

    message.delete().catch(O_o => {});
    reportschannel.send(reportEmbed);
    message.delete();
    return;
}

message.channel.fetchMessages(messageID)会返回承诺而不是邮件，您还应使用fetchMessage代替fetchMessages。
你需要等待这个承诺＆＃34;给你信息＆＃34;然后做你需要的。

message.channel.fetchMessage(messageID).then(messagea => {
    let reportEmbed = new Discord.RichEmbed()
        .setTitle("Reports")
        .setColor("#F7E533")
        .addField("Message", messagea.content)
        .addField("Reported User", `@${messagea.author}`)
        .addField("Reported By", `${message.author} with ID: ${message.author.id}`)
        .addField("Time", message.createdAt)
    let reportschannel = message.guild.channels.find(`name`, botconfig.reportsChannel);
    if (!reportschannel) return message.channel.send("Couldn't find reports channel.");

    message.delete().catch(O_o => {});
    reportschannel.send(reportEmbed);
    message.delete();
    return;
})

此外，我已将messagea更改为messagea.content，因此它实际显示了消息
