slack-api - 使用 Slack RTM api 发布消息

Question

我正在关注这里的教程 https://slackapi.github.io/node-slack-sdk/bots#posting-a-message我很困惑为什么我无法让这部分教程代码工作。我复制并粘贴了本节中的代码，如下

var RtmClient = require('@slack/client').RtmClient;
var RTM_CLIENT_EVENTS = require('@slack/client').CLIENT_EVENTS.RTM;

var bot_token = process.env.SLACK_BOT_TOKEN || ''; //I know the problem is not here.

var rtm = new RtmClient(bot_token);
rtm.start();

var channel = "#general"; //could also be a channel, group, DM, or user ID (C1234), or a username (@don)

// you need to wait for the client to fully connect before you can send messages
rtm.on(RTM_CLIENT_EVENTS.RTM_CONNECTION_OPENED, function () {
  rtm.sendMessage("Hello!", channel);
});

由于教程代码的第一部分有效，所以问题肯定来自最后 3 行代码。大概是事件的问题。我的错误消息是

可能您的机器人尚未加入#general channel 。先邀请他加入 channel 。
