Discord.js 角色更新事件

Question

我正在尝试做的是一个简单的事件记录器，它将在其中输出，例如角色是否丢失/获得了权限。所以我想到了比较两者，然后简单地将它们相减，所以它只显示一个特定的权限。相反，我得到 1 个未定义（权限丢失，检查下面的代码）而其他只是空白，因为根本没有文本（权限获得，检查下面的代码）。我已经做过了，比如公会成员失去角色或获得角色，但它的工作方式不同。

我做错了什么，我该如何从这里继续？

代码：

bot.on("roleUpdate", async (oldRole, newRole) => {


if (oldRole.permissions !== newRole.permissions) {

  if (oldRole.permissions > newRole.permissions) {
    //Permission lost
    let oldPerms = oldRole.serialize()
    let newPerms = newRole.serialize()
    var permLost = Object.keys(oldPerms, newPerms).find(perm => perm[newPerms] - oldPerms)
    const embed = new Discord.RichEmbed()
    .setAuthor(`Role changed permissions`)
    .setColor("#ffc500")
    .setDescription(`**${newRole.toString()} has lost the ${permLost} permission**`)
    .setFooter(`ID: ${newRole.id} ????`)
    .setTimestamp()
    logchannel.send(embed).catch()

} else if (oldRole.permissions < newRole.permissions) {
    //Permission given
    let oldPerms = oldRole.serialize()
    let newPerms = newRole.serialize()
    var permGained = Object.keys(oldPerms, newPerms).filter(perm => perm[newPerms] - oldPerms)
    const embed2 = new Discord.RichEmbed()
    .setAuthor(`Role changed permissions`)
    .setColor("#ffc500")
    .setDescription(`**${newRole.toString()} has been given the ${permGained} permission**`)
    .setFooter(`ID: ${newRole.id} ????`)
    .setTimestamp()
    logchannel.send(embed2).catch()

  }
}

});

我更改了您的一些代码，我认为一切都很好。

client.on("roleUpdate", async (oldRole, newRole) => {

    if (oldRole.permissions !== newRole.permissions) {

        const embed = new Discord.RichEmbed()
            .setAuthor(`Role changed permissions`)
            .setColor("#ffc500")
            .setFooter(`ID: ${newRole.id} ?`)
            .setTimestamp()

        const oldPerms = oldRole.serialize();
        const newPerms = newRole.serialize();

        const permUpdated = [];

        for (const [key, element] of Object.entries(oldPerms)) {
            if (newPerms[key] !== element) permUpdated.push(key);
        }

        if (oldRole.permissions > newRole.permissions) {
            //Permission lost

            embed.setDescription(`**${newRole.toString()} has lost the ${permUpdated.join(", ")} permission**`)
            logchannel.send(embed).catch()

        } else if (oldRole.permissions < newRole.permissions) {
            //Permission given

            embed.setDescription(`**${newRole.toString()} has been given the ${permUpdated.join(", ")} permission**`)
            logchannel.send(embed).catch()

        }
    }

});

我更改了您的新嵌入...因为这些嵌入之间的唯一区别是描述，因此您只需创建一个嵌入并在发送前设置描述。
