Question

每当有人报告该机器人有问题时，我都试图让该机器人DM给我，但是每次运行该命令时，我都会不断收到以下控制台错误：

               user.send('An issue was reported by ' + message.author.username + ' in ' + message.channel.name + ', ' + message.guild.name + ':\n' + args[1-100]);
                 ^

TypeError: Cannot read property 'send' of undefined

    at WebSocket.emit (events.js:310:20)
    at Receiver.receiverOnMessage (C:\Users\me\Desktop\Bot\node_modules\ws\lib\websocket.js:800:20)

这是我的代码：

const user = bot.users.cache.get('698238773657483344');
 case 'report':
            message.channel.bulkDelete(1);
            message.channel.send('report sent')
            console.log('An issue was reported by ' + message.author.username + ' in ' + message.channel.name + ', ' + message.guild.name + ': ' + args);

            user.send('An issue was reported by ' + message.author.username + ' in ' + message.channel.name + ', ' + message.guild.name + ':\n' + args[1-100]);
            break;

注意：那不是我的实际用户ID。

另一个注意事项：代码段是switch循环的一部分，而const位于我的代码的顶部，而不是循环本身

如果有人知道该问题的解决方案，我将不胜感激。

您确定机器人是您的客户端吗？ const bot = new Discord.Client(options); bot.users.cache.get('698238773657483344'); 如果您有客户作为您的客户，请尝试 client.users.cache.get('id')

在我的终端上对其进行了尝试，并且运行良好，我唯一的猜测是该用户尚未被该漫游器缓存。该ID的用户是否与机器人共享公会？阅读here

.users- 在任何时候都已缓存的所有User对象，均按其ID映射

Answer 3

这似乎没有缓存目标用户，您可以使用.fetch() method确保在未缓存的情况下获取它（如果在缓存中可用，则机器人将使用缓存）

// This will fetch the user with the 698238773657483344 ID.
bot.users.fetch("698238773657483344").then(user => {
    // Up to you here to adapt to your code, at this state, if user is undefined
    // it means the ID is wrong / there is an issue while fetching.
});

如果在user情况下只需要report var，则可以这样做：

case 'report':
    bot.users.fetch("698238773657483344").then(user => {
        message.channel.bulkDelete(1);
        message.channel.send('report sent');
        console.log('An issue was reported by ' + message.author.username + ' in ' + message.channel.name + ', ' + message.guild.name + ': ' + args);

        user.send('An issue was reported by ' + message.author.username + ' in ' + message.channel.name + ', ' + message.guild.name + ':\n' + args[1-100]);
    });

    break;
