Discord.js中如何通过Enmap检测属性值？欢迎功能配置故障排查

Let's break down the issues in your code and fix them step by step to get the welcomer setting working as intended.

Key Issues in Your Current Code #

1. Invalid message reference: In the guildMemberAdd event, there's no message object available—you need to use member.guild.id instead of message.guild.id.
2. Misuse of hasProp: Enmap's hasProp method only checks if a property exists, not its value. You should directly retrieve the welcomer boolean and check if it's true.
3. Unchecked channel lookup: If the configured log channel doesn't exist, your bot will crash—add a safety check here.

Corrected guildMemberAdd.js Code #

const config = require("../../config.json");
const vars = require("../../variables.json");
const Discord = require("discord.js");
const defaultSettings = require("../../defaultSettings.js");
const Enmap = require("enmap");

module.exports = async (client, member) => {
  // Ensure the guild has settings (uses defaults if not present)
  client.configs.ensure(member.guild.id, defaultSettings);
  
  // Get the welcomer setting for this guild
  const isWelcomerEnabled = client.configs.get(member.guild.id, "welcomer");
  
  // Exit early if welcomer is disabled
  if (!isWelcomerEnabled) return;

  // Fetch and format the welcome message
  let welcomeMessage = client.configs.get(member.guild.id, "welcomeMessage");
  welcomeMessage = welcomeMessage
    .replace(/%user/g, member.user)
    .replace(/%server/g, member.guild.name)
    .replace(/%total/g, member.guild.memberCount);

  // Create the embed
  const welcomemsg = new Discord.RichEmbed()
    .setTitle(`Hello! :wave:`)
    .setDescription(welcomeMessage)
    .setThumbnail(member.user.avatarURL)
    .setColor(vars.good)
    .setTimestamp()
    .setFooter(`ID: ${member.user.id}`, member.user.avatarURL);

  // Find the log channel and send the message (with safety check)
  const logChannel = member.guild.channels.find(x => x.name === client.configs.get(member.guild.id, "logChannel"));
  if (logChannel) {
    logChannel.send(welcomemsg);
  } else {
    console.log(`Warning: Welcome log channel not found in guild ${member.guild.name}`);
  }
};

Applying the Same Logic to guildMemberRemove #

For your guildMemberRemove event, replicate the same pattern:

1. Use member.guild.id to target the correct guild settings.
2. Check if client.configs.get(member.guild.id, "welcomer") is true before running the goodbye message code.
3. Add a safety check for the log channel.

Additional Notes #

• Make sure your main bot file initializes the Enmap correctly:

  const Enmap = require('enmap');
  client.configs = new Enmap({ name: 'configs' }); // This creates/loads the configs database
  

• When updating the welcomer setting for a guild, use client.configs.set(guildId, false, "welcomer") to disable it, or true to enable it.
