Question

我的代码有问题。

if (command === 'channel'){
    if (args.length == 0 ){
        return message.channel.send(Aucun argument trouvé)
    }
    await message.guild.channels
    .create(args[0] ,{
        type : 'text' ,
    })

    .then((chan)=>{
    var data = fs.readFileSync('test.json')
    var parsedata = JSON.parse(data)



    var test = 0
    console.log(parsedata['category'])

    try {
        chan.setParent( parsedata['category'])
    }catch{

        message.channel.send("il s'emblerais que la commande category est mal été configuré ")
        channel.delete()
        console.log("end")
        return

    }


    });
    message.channel.send("channel "+args[0]+" crée :)")

};

我正在尝试创建一个频道并将其移至一个类别。类别 ID 存储在名为 test.json 的文件中。

我的问题是，如果存储的 ID 不存在，那么 try-catch 应该停止错误并执行 catch 块中的代码。但事实并非如此。

这里是错误：

提前感谢您的帮助

您收到错误，因为父类别不存在。如果要捕获此错误，则需要在 await 前使用 chan.setParent() 关键字（因为 .setParent() 方法是异步的）：

if (command === 'channel') {
  if (args.length === 0) return message.channel.send('Aucun argument trouvé');

  try {
    let chan = await message.guild.channels.create(args[0], {
      type: 'text',
    });

    let data = fs.readFileSync('test.json');
    let parsedata = JSON.parse(data);

    await chan.setParent(parsedata['category']);

    message.channel.send(`channel ${args[0]} crée :)`);
  } catch {
    message.channel.send(
      "il s'emblerais que la commande category est mal été configuré",
    );
    // not sure what channel you want to delete here
    channel.delete();
  }
}
