如何在具有id的特定通道中发送消息

Question

我使用replit数据库保存通道id
这是我的代码:
client.channels.cache.get(db.get(args[1])).send(args[2]);
，我得到这个错误:

client.channels.cache.get(db.get(args[1])).send(args[2]);
^

我猜db.get()返回一个你不能作为值传递的承诺。尝试先检索值，然后获取通道。就像

const id = await db.get(args[1]);
const channel = client.channels.cache.get(id);
channel.send(args[2]);

也有可能id在服务器中存储不正确。看看这个。您可以记录id以检查是否存在这种情况。
