问题原因 #

Discord API要求Slash命令的选项类型必须传入整数类型的类型码，你在代码里给type字段传了字符串"string"，不符合API参数要求，导致请求被拒绝。

另外代码还有几处语法和逻辑错误：

• EmbedBuilder的addFields方法中，每个字段对象缺少name属性
• interaction.reply的参数格式不正确，需包裹在对象里
• 存在未闭合的大括号，会触发语法错误

解决方案 #

1. 导入Discord.js提供的ApplicationCommandOptionType枚举，用它指定选项类型，避免手动输入数值出错
2. 替换所有选项中的type: "string"为type: ApplicationCommandOptionType.String
3. 修复EmbedBuilder和interaction.reply中的错误

修改后的完整代码 #

require("dotenv").config();
const { GatewayIntentBits, ApplicationCommandOptionType, EmbedBuilder } = require("discord.js");
const Discord = require("discord.js");

const client = new Discord.Client({
    intents: [
        GatewayIntentBits.Guilds,
        GatewayIntentBits.GuildMembers,
        GatewayIntentBits.GuildBans,
        GatewayIntentBits.GuildEmojisAndStickers,
        GatewayIntentBits.GuildIntegrations,
        GatewayIntentBits.GuildWebhooks,
        GatewayIntentBits.GuildInvites,
        GatewayIntentBits.GuildVoiceStates,
        GatewayIntentBits.GuildPresences,
        GatewayIntentBits.GuildMessages,
        GatewayIntentBits.GuildMessageReactions,
        GatewayIntentBits.GuildMessageTyping,
        GatewayIntentBits.DirectMessages,
        GatewayIntentBits.DirectMessageReactions,
        GatewayIntentBits.DirectMessageTyping,
        GatewayIntentBits.MessageContent,
        GatewayIntentBits.GuildScheduledEvents
    ]
});

client.on("ready", () => {
    console.log(`Logged in as ${client.user.tag}!`);

    const guildID = "915541815225118740";
    const guild = client.guilds.cache.get(guildID);
    let commands;

    if (guild) {
        commands = guild.commands;
    } else {
        commands = client.application?.commands;
    }

    commands?.create({
        name: "poll",
        description: "Sets up a poll.",
        options: [
            {
                name: "title",
                description: "The title of the poll.",
                required: true,
                type: ApplicationCommandOptionType.String
            },
            {
                name: "content",
                description: "The content of the poll.",
                required: true,
                type: ApplicationCommandOptionType.String
            }
        ]
    });
});

client.on("interactionCreate", async (interaction) => {
    if (!interaction.isCommand()) {
        return;
    }

    const { commandName, options } = interaction;

    if (commandName === "poll") {
        const embed = new EmbedBuilder()
            .setColor(0x0099FF)
            .setTitle(options.getString("title"))
            .addFields(
                {
                    name: "Poll Content",
                    value: options.getString("content"),
                    inline: false
                },
                {
                    name: "Vote Options",
                    value: ":thumbsup: - Yes",
                    inline: true
                },
                {
                    name: "\u200B", // 空名称用于对齐
                    value: ":thumbsdown: - No",
                    inline: true
                }
            );

        await interaction.reply({ embeds: [embed] });
    }
});

client.login(process.env.TOKEN);

额外说明：

• 使用options.getString("title")替代options.get("title")，可更明确获取字符串类型的选项值
• EmbedBuilder的字段必须包含name和value，空名称\u200B用来让第二个和第三个字段保持对齐
• interaction.reply需要传入包含embeds数组的对象，不能直接传Embed实例
