Question

试图建立一个系统，当您说出一个列入黑名单的单词时，它将删除该单词，然后让DM告诉该人该单词被删除的通道，原因以及他说的信息。但是我的代码不断告诉我：

2020-02-25T02:05:30.557281+00:00 app[worker.1]: (node:4) UnhandledPromiseRejectionWarning: DiscordAPIError: Cannot send messages to this user

2020-02-25T02:05:30.557358+00:00 app[worker.1]: (node:4) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 6)

这是我的代码：

bot.on('message', async message => {

  var sender = message.author
  var channel = message.channel.id

  if(sender.id === 'BOT ID') {
    return;
    }


if(message.content.includes('discord.gg/')) {
      message.delete();
      message.author.send(`**Your message in <#${channel}> had been deleted.**  
      \n**__Reason:__** *Promotion*
      \n**__Your Message:__** *${message.content}*`)
  };

Answer 1

该用户可能不允许来自此服务器的DM。您基本上可以拒绝其他用户从特定服务器向您发送DM。为避免显示错误，您需要使用try catch块并进行相应的处理。

Answer 2

用户不允许从该服务器发送DM消息。最好不要使用try - catch构造。如果消息接收成功，方法DM Channel send返回消息promise，如果某些地方出错了，则拒绝err。您可以使用单个块.catch(err => )

处理它

if(message.content.includes('discord.gg/')) {
      message.delete();
      message.author.send(`**Your message in <#${channel}> had been deleted.**  
      \n**__Reason:__** *Promotion*
      \n**__Your Message:__** *${message.content}*`).catch(err => console.log('User don`t allow to send DM message from him'))
  }

Discord JS错误：UnhandledPromiseRejection警告：DiscordAPI错误：无法向该用户发送消息
