Question

我试图让我的机器人检测命令何时无效（在列表中）并返回一条消息，告诉用户该命令无效，我尝试了很多方法，并且一直在说无效每条消息的命令消息，甚至是有效命令。

    if (message.content.startsWith(`${prefix}`)) {
        let commands = ["help", "mod", "ping", "serverinfo", "8ball", "suggest", "coinflip", "botinfo", "avatar", "info", "serverlogo", "ssu", "close"];

        if (!message.content.includes(commands)) {
            return message.channel.send(`Sorry it looks like you have entered an invalid command, Please use ${prefix}help to get a list of useable commands`)
        }
    }

Answer 1

您正在测试错误的方法。您应该测试数组是否包含消息字符串，而不是如果消息字符串包含数组。

if (!commands.includes(message.content)) { // This doesn't work exactly

您需要做的另一件事是从邮件内容和所有后续参数中删除前缀。

if (!commands.includes(message.content.replace(prefix, "").split(' ')[0])) { // This first removes the first instance of the prefix, then gets the first argument, which is the command

Answer 2

您需要从message.content中删除前缀，并且检查方式不正确：

update=TRUE
