如何在discord.js中实现基于关键词的Waifu搜索命令？

Hey there! Let's build that waifu search command you need. I'll walk you through the whole process, from setting up the data to creating the polished embed response.

1. Prepare Your Waifu Data #

First, let's get your waifu JSON ready. You can save it as a separate file (like waifus.json) with the structure you provided:

{
  "waifuID": {
    "1": {
      "names": "Megumin",
      "img_url": "https://s4.anilist.co/file/anilistcdn/character/large/b89361-xH1t0q5WeAN8.png",
      "claims": "#1"
    },
    "2": {
      "names": "Mai Sakurajima",
      "img_url": "https://s4.anilist.co/file/anilistcdn/character/large/b127222-IY5iDRuXLY8i.png",
      "claims": "#2"
    },
    "3": {
      "names": "Zero Two",
      "img_url": "https://s4.anilist.co/file/anilistcdn/character/large/b124381-pkTKi6HHNuVR.png",
      "claims": "#3"
    }
  }
}

Alternatively, you can define the object directly in your code—whichever fits your workflow better.

2. Build the Command Code #

Here's the complete, commented code for your !search command, using discord.js v14 (the latest stable version). I've added little touches to make it user-friendly:

const { Client, GatewayIntentBits, EmbedBuilder } = require('discord.js');
// Import your waifu data (adjust the file path if needed)
const waifuData = require('./waifus.json');

// Initialize the Discord client
const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildMessages,
    GatewayIntentBits.MessageContent // Required to read user message content
  ]
});

// Triggered when the bot finishes logging in
client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}—ready to search waifus!`);
});

// Handle incoming messages
client.on('messageCreate', async (message) => {
  // Ignore messages from other bots to avoid loops
  if (message.author.bot) return;

  // Check if the message starts with our !search command
  if (!message.content.startsWith('!search')) return;

  // Extract the search query (remove the !search prefix and trim extra spaces)
  const searchQuery = message.content.slice(7).trim();

  // Remind the user to enter a waifu name if they didn't
  if (!searchQuery) {
    return message.reply('Hey, you need to tell me which waifu to search! Try `!search Zero Two`');
  }

  // Look for a matching waifu in our data
  let foundWaifu = null;
  // Loop through all waifu entries
  for (const waifu of Object.values(waifuData.waifuID)) {
    // Case-insensitive match so users don't stress about capitalization
    if (waifu.names.toLowerCase() === searchQuery.toLowerCase()) {
      foundWaifu = waifu;
      break; // Stop searching once we find a match
    }
  }

  // If we found a match, build and send the embed
  if (foundWaifu) {
    const waifuEmbed = new EmbedBuilder()
      .setTitle(foundWaifu.names)
      .setImage(foundWaifu.img_url)
      .setColor('#FF69B4') // A cute pink hue for waifu vibes 😊
      .addFields({ name: 'Claim Number', value: foundWaifu.claims, inline: true });

    return message.channel.send({ embeds: [waifuEmbed] });
  } else {
    // Let the user know if their search didn't turn up anything
    return message.reply(`Sorry, I couldn't find a waifu named **${searchQuery}**!`);
  }
});

// Log in to Discord with your bot's token (replace with your actual token)
client.login('YOUR_BOT_TOKEN_HERE');

3. Key Tips & Customizations #

• Intent Setup: Don't forget to enable the Message Content Intent in your Discord Developer Portal (under Bot > Privileged Gateway Intents)—without it, the bot can't read message content.
• v13 Compatibility: If you're using discord.js v13, swap EmbedBuilder for MessageEmbed and send the embed like this: message.channel.send(waifuEmbed) (no need for the embeds array).
• Fuzzy Matching: Want to allow partial matches (e.g., !search Zero finds Zero Two)? Replace the equality check with waifu.names.toLowerCase().includes(searchQuery.toLowerCase()).
• Embed Tweaks: You can add descriptions, change the color, or add more fields to the embed—check the discord.js docs for all available customization options.

Example Output #

When a user sends !search Zero Two, the bot will send an embed that looks like this:

Zero Two
[Image of Zero Two]
Claim Number: #3
