Discord.js：按 ID 获取消息给出了错误的输出

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() 。我想出了点问题，因为当我为我的报告命令输入 ID 时，它 return 作为 [object Promise] 而不是 ID 对应的消息。这是一个代码位及其输出：

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) returns Promise 不是消息，而且你应该使用 fetchMessage 而不是 fetchMessages。
你需要等待那个承诺 "to give you information" 然后做你需要做的事。

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;
})

而且我已经将 messagea 更改为 messagea.content 所以它实际上显示消息
