删除版主的消息命令

Question

我正在开发 Discord 机器人，最近一直在阅读 API。我想为我的 bot 添加一个命令，它将完全清除文本通道，并且只允许具有管理消息权限的人。

到目前为止，这是我的代码：

client.on('message', function(message) {
    if (message.content == "^clear") {
        try {
            if (message.member.hasPermission("MANAGE_MESSAGES")) {
                messages = message.channel.fetchMessages();
                message.channel.bulkDelete(messages);
            }
        } catch(e) {
            message.channel.send("ERROR: ERROR CLEARING CHANNEL.");
            console.log(e);
        }
    }

});

我收到如下错误：

TypeError: The messages must be an Array, Collection, or number.

首先，您不能批量删除超过 14 天的消息，因此如果您尝试清除包含超过 14 天消息的频道，批量删除将不起作用，您必须一次删除一个（while/for 循环），我假设您在文档中知道这一点。其次，message.channel.fetchMessages() returns a Promise 意味着它在您访问它时尚未准备好。您必须使用 async/await 或仅使用 .then。示例：

client.on('message', function(message) {
    if (message.content == "^clear") {
        if (message.member.hasPermission("MANAGE_MESSAGES")) {
            message.channel.fetchMessages()
               .then(function(list){
                    message.channel.bulkDelete(list);
                }, function(err){message.channel.send("ERROR: ERROR CLEARING CHANNEL.")})                        
        }
    }

});

这是非常简单的代码，如果您想要 message.channel.bulkDelete（输入您的自定义号码），因为这只会删除 5 条消息。但请记住，最大值为 100。

/////////////////Clear Chat//////////////////////////////////

client.on("message", message => {
  if(message.content === "/clearchat 5") {
    message.channel.bulkDelete(5)
    .then(messages => console.log(`Bulk deleted ${messages.size} messages`))
    .catch(console.error);
 message.channel.send("Chat cleared");
  }
})
///Make ur own trigger and edit the response/////////////

这是留言。而不是味精。

if(message.content.startsWith(prefix + "clear")){
    const amount = message.content.split(" ")[1];
    if(!amount)
    {
        message.reply(`<amount>`);
        return;
    }
     if(!message.member.hasPermission("MANAGE_MESSAGES"))
     {
        message.channel.send('You have no permissions to do that');
        return;
     }
    message.channel.bulkDelete(amount)
    //.then(messages => message.channel.send(`${messages.size} Messages deleted`))
.then(messages => message.channel.send(`Messages deleted by ${message.author.username}`))
.catch(console.error);
}
