【问题描述】：

我的问题是当我写命令时！ Tempmute（用户）（时间）和字段（时间）我会写例如 10 s / m / h / d 它工作得很好但是当我在这个字段中写其他字母时，机器人就会崩溃。谁能告诉我如何解决它？提前致谢！ 代码：

  if (command === `${prefix}tempmute`) {
    let tomute = message.guild.member(message.mentions.users.first() || message.guild.members.get(args[0]));
    if(!tomute) return message.reply("Nie moge znaleźć określonego użytkownika");
    if(tomute.hasPermission("ADMINISTRATOR")) return message.reply("Ta osoba ma zbyt wysoką rangę lub nie masz permisji!");
    let muterole = message.guild.roles.find(r => r.name === "muted");

    if(!muterole){
      try {
        muterole =  message.guild.createRole({
          name: "muted",
          color: "#0000000",
          permissions: []
        })
        message.guild.channels.forEach(async (channel, id) => {
           channel.overwritePermissions(muterole,{
            SEND_MESSAGES: false,
            ADD_REACTIONS: false
          });
        });
      } catch(e) {
        console.log(e.stack);
      }
    }

    let mutetime = args[1];
    if(!mutetime) return message.reply("Wprowadź czas na jaki ma byc zmutowana osoba")

    tomute.addRole(muterole.id);
    message.reply(`<@${tomute.id}> został zmutowany na ${ms(ms(mutetime))}`);



    setTimeout(function(){
      tomute.id.removeRole(muterole.id);
      message.channel.send(`<@${tomute.id}> został odmutowany!`);
    }, ms(mutetime));

    }
  }

  );

控制台出错：

【问题讨论】：

您可以尝试添加console.log(mutetime) 吗？我认为它是未定义的

标签： javascript discord.js

【解决方案1】：

将您的代码添加到try catch 语句中它不会再崩溃，但是如果您想检查参数是否与您想要的相符，您可以制作一个正则表达式

尝试捕捉：

try
{

}catch(error)
{
console.log(error)
}

正则表达式：

var match = /^(-?(?:\d+)?\.?\d+) *(milliseconds?|msecs?|ms|seconds?|secs?|s|minutes?|mins?|m|hours?|hrs?|h|days?|d|weeks?|w|years?|yrs?|y)?$/i.exec(
    mutetime);
 if(!match)return;
