joinedAtTimeStamp 正在显示 Nan discord.js

Question

我正在编写 userInfo 命令，但是当我使用该命令时，joinedAtTimeStamp 在嵌入中显示 <t:NaN:R>。这是这段代码中唯一的问题。

我的代码：

const { MessageEmbed, ContextMenuInteraction } = require("discord.js");

module.exports = {
    name: "userInfo",
    aliases: ["user"],
    permissions: ["SEND_MESSAGES", "ATTACH_FILES"],
    description: "user",

    async execute(message, args, cmd, client, Discord, profileData) {
        const target = message.mentions.users.first();
        if(!args[0]) {
            const response2 = new MessageEmbed()
            .setColor("RANDOM")
            .setAuthor({name: message.author.tag, iconURL: message.author.displayAvatarURL({dynamic: true})})
            .setThumbnail(message.author.displayAvatarURL({dynamic: true}))
            .addFields(
                {name: "ID", value: message.author.id},
                {name: "Joined Server", value: `<t:${parseInt(message.author.joinedTimestamp / 1000)}:R>`, inline: true},
                {name: "Account Created", value: `<t:${parseInt(message.author.createdTimestamp / 1000)}:R>`, inline: true},
                
            );
            message.reply({embeds:[response2]});
        }
        const response = new MessageEmbed()
            .setColor("RANDOM")
            .setAuthor({name: target.tag, iconURL: target.displayAvatarURL({dynamic: true})})
            .setThumbnail(target.displayAvatarURL({dynamic: true}))
            .addFields(
                {name: "ID", value: target.id},
                {name: "Joined Server", value: `<t:${parseInt(target.joinedTimestamp / 1000)}:R>`, inline: true},
                {name: "Account Created", value: `<t:${parseInt(target.createdTimestamp / 1000)}:R>`, inline: true},
            );
            
        message.reply({embeds: [response], ephemeral: true})
    }
}

我正在使用 discord.js v13 和节点 16。

Answer 1

你能确认 target.joinedTimestamp 的类型吗？

可能是您在这里进行的双重转换：

parseInt(target.joinedTimestamp / 1000)

毁了你的号码。

（您正在将 target.createdTimestamp 转换为数字，将其除以 100（使其成为浮点数），然后通过转换回整数来丢弃浮点数。）

Answer 2

message.author 是 User，它没有 joinedTimestamp 属性，只有 GuildMember 有。 message.member represents the author of the message as a guild member, so you can use that as it will have a joinedTimestamp 属性.

你看到 NaN 而不是正确值的原因是因为 parseInt 将 return NaN 如果你尝试解析 undefined:

console.log('undefined:', parseInt(undefined / 1000, 10));
console.log('3459192421512:', parseInt(3459192421512 / 1000, 10));

以下代码应按预期工作

.addFields(
  { name: 'ID', value: message.author.id },
  {
    name: 'Joined Server',
    value: `<t:${parseInt(message.member.joinedTimestamp / 1000, 10)}:R>`,
    inline: true,
  },
  {
    name: 'Account Created',
    value: `<t:${parseInt(message.author.createdTimestamp / 1000, 10)}:R>`,
    inline: true,
  },
);

至于target，也是一样的问题； message.mentions.users.first() 是一个 User。您可以创建一个新变量，例如targetMember 并分配 message.mentions.members.first()，所以它将是 GuildMember:

const target = message.mentions.users.first();
const targetMember = message.mentions.members.first();

然后，只需替换 target:

.addFields(
  { name: 'ID', value: target.id },
  {
    name: 'Joined Server',
    value: `<t:${parseInt(targetMember.joinedTimestamp / 1000, 10)}:R>`,
    inline: true,
  },
  {
    name: 'Account Created',
    value: `<t:${parseInt(target.createdTimestamp / 1000, 10)}:R>`,
    inline: true,
  },
);

PS: use the radix in parseInt 是个好主意。这就是为什么我在 parseInt.

中添加 10 作为第二个参数的原因
