discord.js crate计算器命令报错：ValidationError期望对象类型值

问题概述 #

我是Discord.js新手，编写了一个计算不同类型crate物品总价值的斜杠命令，命令接收crate类型、物品类型和数量参数来计算总价值，但运行时出现错误。

原代码 #

const { SlashCommandBuilder } = require('discord.js');

const normalMelonValue = 9600;
const normalPineappleValue = 11520;
const LargeMelonValue = 27000;
const LargePineappleValue = 31050;

module.exports = {
    data: new SlashCommandBuilder()
        .setName('crate')
        .setDescription('Crate Calculator')
        .addStringOption(option =>
            option.setName('type')
                .setDescription('The Type of the crate')
                .setRequired(true)
                .addChoice('Normal', 'normal')
                .addChoice('Large', 'large')
        )
        .addStringOption(option =>
            option.setName('item')
                .setDescription('The item to calculate')
                .setRequired(true)
                .addChoice("Melon", "melon")
                .addChoice("Pineapple", "pineapple")
        )
        .addIntegerOption(option =>
            option.setName('amount')
                .setDescription('The amount of the item to calculate')
                .setRequired(true),
        ),
    async execute(interaction) {
        const crateSize = interaction.options.getString('type');
        const item = interaction.options.getString('item');
        const amount = interaction.options.getInteger('amount');

        let totalValue = 0;
        if (crateSize === 'normal') {
            if (item === 'melon') {
                totalValue = normalMelonValue * amount;
            } else if (item === 'pineapple') {
                totalValue = normalPineappleValue * amount;
            }
        } else if (crateSize === 'large') {
            if (item === 'melon') {
                totalValue = LargeMelonValue * amount;
            } else if (item === 'pineapple') {
                totalValue = LargePineappleValue * amount;
            }
        }

        await interaction.reply(`I have calculated ${amount} ${item} from ${crateSize} crate, and the total value is ${totalValue}$`)
    },
};

}

错误原因 #

报错核心是addChoice的API使用错误。Discord.js v14及后续版本中，@discordjs/builders包要求addChoice方法接收一个包含name（用户可见的选项文本）和value（后台获取的实际值）的对象，不再支持直接传入两个字符串参数。

修复后的代码 #

const { SlashCommandBuilder } = require('discord.js');

const normalMelonValue = 9600;
const normalPineappleValue = 11520;
const LargeMelonValue = 27000;
const LargePineappleValue = 31050;

module.exports = {
    data: new SlashCommandBuilder()
        .setName('crate')
        .setDescription('Crate Calculator')
        .addStringOption(option =>
            option.setName('type')
                .setDescription('The Type of the crate')
                .setRequired(true)
                .addChoice({ name: 'Normal', value: 'normal' })
                .addChoice({ name: 'Large', value: 'large' })
        )
        .addStringOption(option =>
            option.setName('item')
                .setDescription('The item to calculate')
                .setRequired(true)
                .addChoice({ name: "Melon", value: "melon" })
                .addChoice({ name: "Pineapple", value: "pineapple" })
        )
        .addIntegerOption(option =>
            option.setName('amount')
                .setDescription('The amount of the item to calculate')
                .setRequired(true)
        ),
    async execute(interaction) {
        const crateSize = interaction.options.getString('type');
        const item = interaction.options.getString('item');
        const amount = interaction.options.getInteger('amount');

        let totalValue = 0;
        if (crateSize === 'normal') {
            totalValue = item === 'melon' ? normalMelonValue * amount : normalPineappleValue * amount;
        } else if (crateSize === 'large') {
            totalValue = item === 'melon' ? LargeMelonValue * amount : LargePineappleValue * amount;
        }

        await interaction.reply(`已计算 ${amount} 个 ${item}（来自${crateSize} crate），总价值为 ${totalValue}$`)
    },
};

额外优化说明 #

• 将嵌套的if-else简化为三元表达式，让代码更简洁
• 把回复文本改成中文，更符合使用习惯（如果不需要可以改回英文）
