如何在这段selfcore JavaScript代码中使用多个channel_id参数？

实现方案 #

你只需要将需要监听的频道ID存入数组，通过数组的includes方法判断当前消息的频道ID是否在监听列表中即可完成需求，修改后的代码如下：

import selfcore from "selfcore";

const client = new selfcore();
const gateway = new selfcore.Gateway("ODQ4MDIzNxjc0MDxxx4Mzk0.YS45RA.xxxxxxxxxQYflQE");

// 填入所有需要监听的频道ID
const LISTEN_CHANNELS = [
  "882134793771425843",
  "替换为第二个频道ID",
  "替换为第三个频道ID"
];
// 目标转发Webhook地址
const TARGET_WEBHOOK = "https://discord.com/api/webhooks/xxxxxxxxxx/drO_0pcypQ03HFWAdVN799DpUQKVfUukvf8wM82IZxfGOEK0Mxxxxxxxxxxx";

gateway.on("message", (m) => {
  // 匹配当前消息是否来自监听列表内的频道
  if (LISTEN_CHANNELS.includes(m.channel_id)) {
    let content = m.content ? m.content : { embeds: [m.embeds[0]] };
    client.sendWebhook(TARGET_WEBHOOK, content);
  }
});

扩展：不同频道转发到不同Webhook #

如果你需要把不同频道的消息转发到不同的Webhook地址，可以用对象映射的方式实现：

import selfcore from "selfcore";

const client = new selfcore();
const gateway = new selfcore.Gateway("ODQ4MDIzNxjc0MDxxx4Mzk0.YS45RA.xxxxxxxxxQYflQE");

// 键为频道ID，值为对应要转发的Webhook地址
const CHANNEL_WEBHOOK_MAP = {
  "882134793771425843": "频道1对应Webhook地址",
  "第二个频道ID": "频道2对应Webhook地址",
  "第三个频道ID": "频道3对应Webhook地址"
};

gateway.on("message", (m) => {
  const targetWebhook = CHANNEL_WEBHOOK_MAP[m.channel_id];
  if (targetWebhook) {
    let content = m.content ? m.content : { embeds: [m.embeds[0]] };
    client.sendWebhook(targetWebhook, content);
  }
});
