搭建Discord音乐Bot加载命令时遇DiscordAPIError错误求助

我正在为Discord频道搭建音乐Bot，但加载命令时持续出错，哪怕使用Discord官方文档的示例代码也会触发问题。

示例代码 #

const { REST, Routes } = require("discord.js");
const { Client, GatewayIntentBits } = require("discord.js");
const client = new Client({ intents: [GatewayIntentBits.Guilds] });

const CLIENT_ID = "ID";

const TOKEN =
  "token";

const commands = [
  {
    name: "ping",
    description: "Replies with Pong!",
  },
];

const rest = new REST({ version: "10" }).setToken(TOKEN);

(async () => {
  try {
    await rest.put(Routes.applicationCommands(CLIENT_ID), {
      headers: { authorization: `Bot ${TOKEN}` },
      body: commands,
    });

  } catch (error) {
    console.error(error);
  }
})();

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

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

  if (interaction.commandName === "ping") {
    await interaction.reply("Pong!");
  }
});

client.login(TOKEN);

问题原因与解决办法 #

• 问题根源：你已经通过rest.setToken(TOKEN)完成了令牌配置，却又在请求的headers里重复添加authorization字段，导致请求体解析异常，触发"无描述信息"错误。
• 修复步骤：
  1. 移除请求配置中的headers属性，rest.setToken会自动处理授权头。
  2. 确保CLIENT_ID和TOKEN替换为你Bot的真实ID与令牌。
  3. 重新运行代码，命令即可正常加载。

修改后的核心代码片段：

(async () => {
  try {
    await rest.put(Routes.applicationCommands(CLIENT_ID), {
      body: commands,
    });

  } catch (error) {
    console.error(error);
  }
})();
