【问题描述】：

我正在尝试对我的命令进行确认部分，如果您激活该命令，则需要在代码激活之前说“是”。重复出现的问题是消息后面的代码

已确认...请稍候。

在此之后，它完全跳过代码并且什么都不做。当我在 VSC 中编写代码时，代码的 async 部分没有用黄色突出显示，而是更多的是更深的黄色。

我已尝试删除这部分代码 const async = async () => 但是除非连接到异步，否则带有等待的代码无法运行。 我试过改变异步的运行方式。 async () => 结果还是一样。 删除开始的异步代码也只会导致命令中断。 我已经将大块代码放在then(collected 代码之外，但是在命令激活时等待几秒钟后，它立即运行，然后出现值错误。但我希望它在作者说“是”时激活代码

async run(message, args)

if (message.channel instanceof Discord.DMChannel) return message.channel.send('This command cannot be executed here.')

let replyMessage = message.reply('Please make sure that my integration role "Synthibutworse" is above the default role used for this server. Is this correct? [Reply with "YES"] if so. Will expire in 20 seconds...');

let filter = msg => msg.author.id == message.author.id && msg.content.toLowerCase() == 'yes';
message.channel.awaitMessages(filter, max: 1, time: 20000).then(collected => 

  message.reply('Confirmed... Please wait.');

  const async = async () => 

  if(!message.member.guild.me.hasPermission(['MANAGE_WEBHOOKS'])) return message.channel.send('I don\'t have the permissions to make webhooks, please contact an admin or change my permissions!')
  if(!message.member.guild.me.hasPermission(['MANAGE_ROLES'])) return message.channel.send('I don\'t have the permissions to make roles, please contact an admin or change my permissions!')
  if (!message.member.hasPermission(['MANAGE_WEBHOOKS'])) return message.channel.send('You need to be an admin or webhook manager to use this command.')
  if (!message.member.hasPermission(['MANAGE_ROLES'])) return message.channel.send('You need to be an admin or role manager to use this command.')

  const avatar = `https://cdn.discordapp.com/attachments/515307677656678420/557050444954992673/Generic5.png`;
  const name2 = "SYNTHIBUTWORSE-1.0WOCMD";

  let woaID = message.mentions.channels.first(); 
  if(!woaID) return message.channel.send("Channel is nonexistant or command was not formatted properly. Please do s!woa #(channelname)"); 
  let specifiedchannel = message.guild.channels.find(t => t.id == woaID.id);; 

  const hook = await woaID.createWebhook(name2, avatar).catch(error => console.log(error))
  await hook.edit(name2, avatar).catch(error => console.log(error))
  message.channel.send("Please do not tamper with the webhook or else the command implied before will no longer function with this channel.")

  var role = message.guild.createRole(
      name: `Synthibutworse marker v1.0`,
      color: 0xcc3b3b,).catch(console.error);

  specifiedchannel.send("Created role...");

  if(message.guild.roles.name == "Synthibutworse marker v1.0") 
    role.setMentionable(false, 'SBW Ping Set.')
    role.setPosition(1)
    role.setPermissions(['CREATE_INSTANT_INVITE', 'SEND_MESSAGES'])
      .then(role => console.log(`Edited role`))
      .catch(console.error);

  message.channel.send("Role set up...");

  const sbwrID = message.guild.roles.find(`Synthibutworse marker v1.0`);
  let specifiedrole = message.guild.roles.find(r => r.id == sbwrID.id)

  message.channel.send('Created Role... Please wait.');

  message.guild.specifiedchannel.replacePermissionOverwrites(
    overwrites: [
      
         id: specifiedrole,
         denied: ['SEND_MESSAGES'],
         allowed: ['VIEW_CHANNEL'],
      ,
    ],
      reason: 'Needed to change permissions'
    );

  var bot = message.client
  bot.on('message', function(message)  
      if(webhook.name == `Synthibutworse marker`) return
      if(message.channel.id == webhook.channelID) return 
  let bannedRole = message.guild.roles.find(role => role.id === specifiedrole);
  message.member.addRole(bannedRole);
  );

);

;
module.exports = woa;

我希望命令以异步方式运行，并在消息作者说“是”时继续执行代码，而不是在 Please wait. 消息处停止。

实际发生的情况是代码没有在Please wait 消息之后立即运行。

【参考方案1】：

在您当前的代码中，您声明了一个异步函数，但从未调用它。这就是代码从不运行以及 VSC 将其名称变暗的原因。

解决方案： 将您的awaitMessages(...) 的.then() 回调定义为async：

.then(async collected => 
  // do async stuff
);

为了将来参考，如果您需要在无法将函数定义为异步的地方使用异步代码，请使用以下设置：

(async function() 
  // do async stuff
)();
