如何批量删除不包括固定邮件的邮件

Question

我制作了一个名为clear的脚本。这个脚本按预期工作。

但是，我的clear脚本如何跳过通道中的固定消息？

这是我的脚本：

const discord = require("discord.js");
module.exports.run = async (bot, message, args) => {

if (message.deletetable) {
message.delete(); 
}
// Member doesn't have permission
if (!message.member.hasPermission("MANAGE_MESSAGES")) {
return message.channel.send("You can't delete messages...") // .then(m => m.delete(5000));
}
// Check if args[0] is a number
if (isNaN(args[0]) || parseInt(args[0]) <= 0) {
return message.channel.send("Yeah... That's not a number? I also can't delete 0 messages by the way.") // .then(m => m.delete(5000));
}
// Maybe the bot can't delete messages
if (!message.guild.me.hasPermission("MANAGE_MESSAGES")) {
return message.channel.send("Sorry... I can't delete messages.") // .then(m => m.delete(5000));
}
let deleteAmount;
if (parseInt(args[0]) > 100) {
deleteAmount = 100;
} else {
deleteAmount = parseInt(args[0]);
}
message.channel.bulkDelete(deleteAmount, true)
.then(deleted => message.channel.send(`I deleted `${deleted.size}` messages.`))
.catch(err => message.channel.send(`Something went wrong... ${err}`));
}   

module.exports.help = {
name: "clear"
}

我希望有人能帮助我，因为这将是我清晰剧本的一个很好的补充。

Answer 1

获取通道的所有消息，然后固定消息，对filter进行差异处理，只保留未固定的消息，然后删除这些消息。

client.on("message", async message => {
if (message.author.bot) return;
if (message.content === "/bulk") {
const allMessages = await message.channel.messages.fetch()
const deletable = allMessages.filter(message => !message.pinned)
await message.channel.bulkDelete(deletable, true)
}
});

虽然Zoolly的答案有效，但它没有考虑deleteAmount——用户想要删除的消息数量。默认情况下，MessageManager#fetch将获取最多50条消息。

使用limit选项获取正确数量的消息：

await message.channel.bulkDelete(
// Fetch the messages
(await message.channel.messages.fetch({limit: deleteAmount}))
// Only include the unpinned messages
.filter(message => !message.pinned),
// This parameter (filterOld) ensures that discord.js filters out messages
// older than 2 weeks before making the request to Discord.
// Messages older than 2 weeks cannot be deleted with this method and
// the Discord API will return an error if messages older than 2 weeks are
// attempted to be bulk deleted.
true
)

适用于discord.js v12和v13。
