如何为我的机器人编写带原因函数的踢球

Question

我试图让我的代码有理由踢人，然后私信他们说他们已经从<server> 踢出<reason>。目前它没有发送原因。

在网上看了教程，但没有运气。我也问过一些人，但他们也不知道。似乎没有多少人使用 discord.js，任何帮助将不胜感激。 =)

Message Bot SendsMessage I Sent

const Discord = require('discord.js');
const { token } = require('./config.json');
var { prefix, logchannel } = require('./config.json');
const client = new Discord.Client();

client.once('ready', () => {
  console.log('Bot loaded!');
  client.user.setActivity('SUPPORT: !info', {
    type: 'PLAYING'
  });
})


client.on('message', message => {

  if (message.content === `${prefix}ping`) {
    message.channel.send('Pong.');
    console.log(`COMMAND: ${message.member.displayName} issued ping command.`);
  } else if (message.content === `${prefix}info`) {
    message.channel.send(`This server's name is: ${message.guild.name}
It has ${message.guild.memberCount} total members.
It is running **WastefulBot** by **USER HIDDEN**

    console.log(`COMMAND: ${message.member.displayName} issued info command.`);
  } else if (message.content === `${prefix}help`) {
    console.log(`COMMAND: ${message.member.displayName} issued help command.`);
    message.delete();
    message.channel.send('Please check your dm\'s.');
    message.member.send(`__**WastefulBot Help**__
!ping | Pong.
!info | Returns information on the server and how to get support for the bot.
!donate | Get information on how to donate.
!help | Shows this information.

`);
  }

  if (message.content === (`${prefix}setlog`)) {

      message.channel.send('Sorry. This command is currently WIP.');
      console.log(`WARNING: ${message.member.displayName} issued setlog command, this command is WIP and does not work.`);
    }

        if (member.kickable == false) {
          message.channel.send("That user cannot be kicked!");
          return;
        } else {
          member.send(`You have been kicked from \`\`${message.guild.name}\`\` for the reason ${reason}.`).then((message) => {
            member.kick(reason).then((member) => {
              message.channel.send("???? " + member.displayName + " has been kicked!");
              console.log(`KICK: ${message.member.displayName} successfully executed kick command.`);
            });
          });
        }
      }
    } else {
      message.channel.send("You do not have permission to use kick.");
      return;
    }
  }

  //End of kick mthd
  else if (message.content.startsWith(`${prefix}staff`)) {
    if (message.member.hasPermission("MANAGE_ROLES")) {

      } else {
        let member = message.mentions.members.first();
        member.addRole("569174153337503804");
        message.channel.send(`Granted ${member.displayName} staff!`);
        message.channel.send(`Warning this command will not have worked on most servers as it is WIP.`);
        console.log(`STAFF: ${message.member.displayName} successfully granted ${member.displayName} staff .`);
      }

    } else {

      return;
    }
  }

});

client.login(token);

Answer 1

说明：

看看你的错误，这是问题的时间表。

1. 这一切的根源是由于他们在公会 (here) 内的隐私设置，机器人无法向成员发送 DM。这会导致 member.send(...) 被拒绝。
2. 由于没有捕获到这个被拒绝的承诺，因此代码继续以 .then() 不返回任何内容而不是预期的 message 参数。
3. 当您尝试读取message.member 的displayName 属性时，会引发错误，因为您的参数message 从未返回。

解决办法：

实现一个.catch() 方法来处理被拒绝的promise的可能性。

请记住，您必须将您的函数声明为异步才能使用await：

client.on('message', async message => { // ES6

然后，在你的命令中：

await member.send(`You have been kicked from \`${message.guild.name}\`. Reason: \`${reason}\``)
  .catch(err => message.channel.send(`⚠ Unable to alert ${member} of reason.`));

await member.kick(reason);
await message.channel.send(`? ${member} has been kicked!`);

console.log(`${message.author.tag} kicked ${member.user.tag} from '${message.guild.name}'.`);

Answer 2

由于隐私设置，您的机器人可能无法在用户被踢出后向他们发送消息。因为用户被踢了，他们不再与机器人共享服务器（除非它是一个非常全球使用的机器人，这会增加用户在多个服务器中使用机器人的几率），这意味着机器人的可能性是无法向该用户发送 DM，这是非常高的。

Answer 3

您的原因代码应该是：

const reason = message.content.split(' ').splice(2)

数字 3 代表命令中原因开始的单词。 例如>踢@原因

所以>kick 将是0，然后@<user> 将是1 和reason 将是2，所以基本上 splice 是它停止的单词，每个单词在 2 之后将是你的理由，包括 2 如果这是有道理的。

我尽力解释了:)

Answer 4

下面不是答案，用户和会员都有.send()

您的代码中的错误是member.send()。你看，member 和user 是两个不同的东西。 .send() 仅适用于 user, so you should do member.user.send()，它会起作用。
此外，您将需要对该承诺进行捕捉，因此如果该用户禁用了 DM，因为如果他们禁用了该机器人，则该机器人无法 DM 用户。比如：

await member.user.send(`You have been kicked!`)
  .catch(() => message.channel.send("User seems to have DMs disabled!"));
await member.kick("reason")
  .then(member => message.channel.send(`${member.displayName} has been kicked!`))
  .catch(e => console.error(e.stack));

请记住，await 是 another way 在异步函数中链接 then。
