Question

我正在研究Discord bot并且最近一直在阅读API。我想为我的机器人添加一个命令，它将完全清除文本频道，并且只允许有权管理消息的人。

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);
        }
    }

});

我收到的错误如下：

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

Answer 1

对于初学者，您无法批量删除超过14天的邮件，因此如果您尝试清除包含超过14天邮件的频道，则无法批量删除，您必须将其删除一次一个（而/ for循环），我假设你知道这是在文档上。其次，message.channel.fetchMessages()会返回Promise，表示您在访问它时尚未就绪。您必须使用async/await或.then。例如：

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.")})                        
        }
    }

});

这是留言。而不是为味精。

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);
}

这是非常简单的代码，如果您要在message.channel.bulkDelete（键入您的自定义编号）中输入密码，这只会删除5条消息。但是请记住，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/////////////
