所以我一直在互联网上搜索，试图找到一种可能的方法来发出清除命令。现在我已经找到了很多不同的方法来制作一个，但是它们都不是以我想要的方式适合我，或者只是为我工作。 首先，这是我的代码
const Discord = require("discord.js"); // use discord.js
const BOT_TOKEN = "secret bot token :)" // bot's token
const PREFIX = "*" // bot's prefix
var eightball = [ // sets the answers to an eightball
"yes!",
"no...",
"maybe?",
"probably",
"I don't think so.",
"never!",
"you can try...",
"up to you!",
]
var bot = new Discord.Client(); // sets Discord.Client to bot
bot.on("ready", function() { // when the bot starts up, set its game to Use *help and tell the console "Booted up!"
bot.user.setGame("Use *info") // sets the game the bot is playing
console.log("Booted up!") // messages the console Booted up!
});
bot.on("message", function(message) { // when a message is sent
if (message.author.equals(bot.user)) return; // if the message is sent by a bot, ignore
if (!message.content.startsWith(PREFIX)) return; // if the message doesn't contain PREFIX (*), then ignore
var args = message.content.substring(PREFIX.length).split(" "); // removes the prefix from the message
var command = args[0].toLowerCase(); // sets the command to lowercase (making it incase sensitive)
var mutedrole = message.guild.roles.find("name", "muted");
if (command == "help") { // creates a command *help
var embedhelpmember = new Discord.RichEmbed() // sets a embed box to the variable embedhelpmember
.setTitle("**List of Commands**\n") // sets the title to List of Commands
.addField(" - help", "Displays this message (Correct usage: *help)") // sets the first field to explain the command *help
.addField(" - info", "Tells info about myself :grin:") // sets the field information about the command *info
.addField(" - ping", "Tests your ping (Correct usage: *ping)") // sets the second field to explain the command *ping
.addField(" - cookie", "Sends a cookie to the desired player! :cookie: (Correct usage: *cookie @username)") // sets the third field to explain the command *cookie
.addField(" - 8ball", "Answers to all of your questions! (Correct usage: *8ball [question])") // sets the field to the 8ball command
.setColor(0xFFA500) // sets the color of the embed box to orange
.setFooter("You need help, do you?") // sets the footer to "You need help, do you?"
var embedhelpadmin = new Discord.RichEmbed() // sets a embed box to the var embedhelpadmin
.setTitle("**List of Admin Commands**\n") // sets the title
.addField(" - say", "Makes the bot say whatever you want (Correct usage: *say [message])")
.addField(" - mute", "Mutes a desired member with a reason (Coorect usage: *mute @username [reason])") // sets a field
.addField(" - unmute", "Unmutes a muted player (Correct usage: *unmute @username)")
.addField(" - kick", "Kicks a desired member with a reason (Correct usage: *kick @username [reason])") //sets a field
.setColor(0xFF0000) // sets a color
.setFooter("Ooo, an admin!") // sets the footer
message.channel.send(embedhelpmember); // sends the embed box "embedhelpmember" to the chatif
if(message.member.roles.some(r=>["bot-admin"].includes(r.name)) ) return message.channel.send(embedhelpadmin); // if member is a botadmin, display this too
}
if (command == "info") { // creates the command *info
message.channel.send("Hey! My name is cookie-bot and I'm here to assist you! You can do *help to see all of my commands! If you have any problems with the Minecraft/Discord server, you can contact an administrator! :smile:") // gives u info
}
if (command == "ping") { // creates a command *ping
message.channel.send("Pong!"); // answers with "Pong!"
}
if (command == "cookie") { // creates the command cookie
if (args[1]) message.channel.send(message.author.toString() + " has given " + args[1].toString() + " a cookie! :cookie:") // sends the message saying someone has given someone else a cookie if someone mentions someone else
else message.channel.send("Who do you want to send a cookie to? :cookie: (Correct usage: *cookie @username)") // sends the error message if no-one is mentioned
}
if (command == "8ball") { // creates the command 8ball
if (args[1] != null) message.reply(eightball[Math.floor(Math.random() * eightball.length).toString(16)]); // if args[1], post random answer
else message.channel.send("Ummmm, what is your question? :rolling_eyes: (Correct usage: *8ball [question])"); // if not, error
}
if (command == "say") { // creates command say
if (!message.member.roles.some(r=>["bot-admin"].includes(r.name)) ) return message.reply("Sorry, you do not have the permission to do this!");
var sayMessage = message.content.substring(4)
message.delete().catch(O_o=>{});
message.channel.send(sayMessage);
}
if(command === "purge") {
let messagecount = parseInt(args[1]) || 1;
var deletedMessages = -1;
message.channel.fetchMessages({limit: Math.min(messagecount + 1, 100)}).then(messages => {
messages.forEach(m => {
if (m.author.id == bot.user.id) {
m.delete().catch(console.error);
deletedMessages++;
}
});
}).then(() => {
if (deletedMessages === -1) deletedMessages = 0;
message.channel.send(`:white_check_mark: Purged \`${deletedMessages}\` messages.`)
.then(m => m.delete(2000));
}).catch(console.error);
}
if (command == "mute") { // creates the command mute
if (!message.member.roles.some(r=>["bot-admin"].includes(r.name)) ) return message.reply("Sorry, you do not have the permission to do this!"); // if author has no perms
var mutedmember = message.mentions.members.first(); // sets the mentioned user to the var kickedmember
if (!mutedmember) return message.reply("Please mention a valid member of this server!") // if there is no kickedmmeber var
if (mutedmember.hasPermission("ADMINISTRATOR")) return message.reply("I cannot mute this member!") // if memebr is an admin
var mutereasondelete = 10 + mutedmember.user.id.length //sets the length of the kickreasondelete
var mutereason = message.content.substring(mutereasondelete).split(" "); // deletes the first letters until it reaches the reason
var mutereason = mutereason.join(" "); // joins the list kickreason into one line
if (!mutereason) return message.reply("Please indicate a reason for the mute!") // if no reason
mutedmember.addRole(mutedrole) //if reason, kick
.catch(error => message.reply(`Sorry ${message.author} I couldn't mute because of : ${error}`)); //if error, display error
message.reply(`${mutedmember.user} has been muted by ${message.author} because: ${mutereason}`); // sends a message saying he was kicked
}
if (command == "unmute") { // creates the command unmute
if (!message.member.roles.some(r=>["bot-admin"].includes(r.name)) ) return message.reply("Sorry, you do not have the permission to do this!"); // if author has no perms
var unmutedmember = message.mentions.members.first(); // sets the mentioned user to the var kickedmember
if (!unmutedmember) return message.reply("Please mention a valid member of this server!") // if there is no kickedmmeber var
unmutedmember.removeRole(mutedrole) //if reason, kick
.catch(error => message.reply(`Sorry ${message.author} I couldn't mute because of : ${error}`)); //if error, display error
message.reply(`${unmutedmember.user} has been unmuted by ${message.author}!`); // sends a message saying he was kicked
}
if (command == "kick") { // creates the command kick
if (!message.member.roles.some(r=>["bot-admin"].includes(r.name)) ) return message.reply("Sorry, you do not have the permission to do this!"); // if author has no perms

message.reply(`${kickedmember.user.username} has been kicked by ${message.author.username} because: ${kickreason}`); // sends a message saying he was kicked
}
});
bot.login(BOT_TOKEN); // connects to the bot
除了package.json，package-lock.json和所有node_modules之外，它是我的bot文件夹中唯一的文件。
我要做的是输入discord * purge [我要清除的邮件数量]并让机器人删除我要求删除的邮件数量，加上我输入的命令（例如，如果我要求机器人删除5条消息，他会删除包含* purge 5消息的6条消息。
非常感谢任何帮助，谢谢！

您正在寻找的是Discord.js的this（bulkDelete()）方法。
它会批量删除邮件，只需简单地传入方法中的邮件集合，它就会为您完成工作。
（您可以使用频道中的messages媒体资源，否则如果您更喜欢承诺，请尝试使用fetchMessages()方法。）
确保频道不是语音频道或DM频道。最后，您的机器人也需要获得许可。
您可以使用message.guild.member(client).permissions获得自己机器人对机器人的权限，或者您可以直接使用message.guild.member(client).hasPermission(permission)，它会返回一个布尔值，用于确定您的机器人是否拥有所需的权限。
（hasPermission()的方法文档是here）
答案 1 :(得分：0)
请注意确定这是否仍然相关，但这是我在我的机器人中使用的
if (!suffix) {
var newamount = "2";
} else {
var amount = Number(suffix);
var adding = 1;
var newamount = amount + adding;
}
let messagecount = newamount.toString();
msg.channel
.fetchMessages({
limit: messagecount
})
.then(messages => {
msg.channel.bulkDelete(messages);
// Logging the number of messages deleted on both the channel and console.
msg.channel
.send(
"Deletion of messages successful. \n Total messages deleted including command: " +
newamount
)
.then(message => message.delete(5000));
console.log(
"Deletion of messages successful. \n Total messages deleted including command: " +
newamount
);
})
.catch(err => {
console.log("Error while doing Bulk Delete");
console.log(err);
});
基本功能是指定要清除的消息数量，它将删除许多加上使用的命令，完整示例为here
