检查用户是否可以在特定通道discord.js中发送消息

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

client.on('message', async message => {
  if (message.content.startsWith('!checkpermission')) {
    // 获取频道对象
    const channel = message.channel;

    // 验证用户权限
    const permissionOverwrites = channel.permissionOverwrites;

    // 检查用户权限
    const user = message.author;
    const userPermissions = getUserPermissions(permissionOverwrites, user);

    // 判断用户权限
    if (userPermissions.canSendMessages) {
      message.reply('你有权限发送消息！');
    } else {
      message.reply('你没有权限发送消息！');
    }
  }
});

// 获取用户权限
function getUserPermissions(permissionOverwrites, user) {
  let userPermissions = {
    canSendMessages: true, // 默认为true，即有权限发送消息
  };

  permissionOverwrites.forEach(permission => {
    // 根据用户对象或者用户ID等方式来判断用户权限
    if (permission.type === 'member' && permission.id === user.id) {
      if (permission.deny.has('SEND_MESSAGES')) {
        userPermissions.canSendMessages = false;
      }
    }
  });

  return userPermissions;
}

client.login('your-token-goes-here');
