Question

我知道我无法使用漫游器删除超过100个，但是我可以重新启动脚本来删除更多吗？
这是我当前的代码：

const CLEAR_MESSAGES = '!clearmessages';

const Discord = require('discord.js');
const bot = new Discord.Client();

const token = 'mytoken';

bot.on('ready', () => {
  console.log('!clearmessages to run...');
  bot.on('message', message => {
    if (message.content == CLEAR_MESSAGES) {

      if (message.channel.type == 'text') {
        message.channel.fetchMessages()
          .then(messages => {
            message.channel.bulkDelete(messages);
            messagesDeleted = messages.array().length;

            message.channel.sendMessage("Number of deleted messages: "+messagesDeleted);
            console.log('Number of deleted messages: '+messagesDeleted)
          })
          .catch(err => {
            console.log('error.');
            console.log(err);
          });
      }
    }
  });
});

bot.login(token);

的确，bulkDelete()一次不能删除100条以上的消息，但是只要有剩余，您就可以检查和删除消息。当邮件的时间超过两周时，您需要一个一个地删除它们。
您可以使用递归异步函数，该函数将一直运行直到没有剩余消息为止。请记住，通过这种方式，您将删除所有频道中的消息。

bot.on('message', async message => {
  if (message.content == CLEAR_MESSAGES) {
    let messagesDeleted = await clearChannel(message.channel);

    message.channel.sendMessage("Number of deleted messages: " + messagesDeleted);
    console.log('Number of deleted messages: ' + messagesDeleted)
  }
});

async function clearChannel(channel, n = 0, old = false) {
  let collected = await channel.fetchMessages();
  if (collected.size > 0) {
    if (old) {
      for (let msg of collected.array()) {
        await msg.delete();
        n++;
      }
    } else {
      let deleted = await channel.bulkDelete(100, true);
      if (deleted.size < collected.size) old = true;
      n += deleted;
    }

    return n + await clearChannel(channel, old);
  } else return 0;
}

类似的操作将重复该循环4次，每次删除50条消息

let msgs = 0;
bot.on('ready', () => {
   console.log('!clearmessages to run...');
   bot.on('message', async message => {
      if (message.content == CLEAR_MESSAGES) {


         for (let index = 0; index <= 3; index++) {
            if (message.channel.type == 'text') {
               await message.channel.fetchMessages()
                  .then(async  messages => {
                     await message.channel.bulkDelete(messages);
                     messagesDeleted = messages.array().length;

                     msgs = msgs + messagesDeleted;
                  })
                  .catch(err => {
                     console.log('error.');
                     console.log(err);
                  });
            }
         }
         console.log(`Total number of messages deleted ${msgs}`);
         message.channel.sendMessage(`Total number of messages deleted ${msgs}`);
      }
   });
});

如何一次删除100条以上的邮件？
