【问题描述】：

我正在我的服务器上运行一个不和谐的机器人。我想让机器人message.react() 处理我刚刚收到的消息。当我运行它时，它工作正常，直到我发送一条消息。

我收到此错误：

/Users/*****/Projects/Discord/DiscordBot/bot.js:22
    .react("????")
     ^

TypeError: message.react is not a function
    at DiscordClient.bot.on (/Users/revel/Projects/Discord/DiscordBot/bot.js:22:6)
    at DiscordClient.emit (events.js:189:13)
    at DiscordClient.handleWSMessage (/Users/revel/Projects/Discord/DiscordBot/node_modules/discord.io/lib/index.js:1854:11)
    at WebSocket.emit (events.js:189:13)

    at Receiver.finish (/Users/revel/Projects/Discord/DiscordBot/node_modules/ws/lib/Receiver.js:541:12)

这是我的代码：

var Discord = require("discord.io");
var logger = require("winston");
var auth = require("./auth.json");
// Configure logger settings
logger.remove(logger.transports.Console);
logger.add(new logger.transports.Console(), 
  colorize: true,
);
logger.level = "debug";
// Initialize Discord Bot
var bot = new Discord.Client(
  token: auth.token,
  autorun: true,
);
bot.on("ready", function (evt) 
  logger.info("Connected");
  logger.info("Logged in as: ");
  logger.info(bot.username + " - (" + bot.id + ")");
);
bot.on("message", (message) => 
  message.react("????");
);

我正在运行discord.js 版本12.2.0 你能帮忙吗？

【问题讨论】：

这不是 Discord.js，这是 Discord.io

【参考方案1】：

刚刚快速浏览了discord.io's docs， 您应该将message 事件的参数替换为正确的参数，如链接中所述：

client.on('message', function(user, userID, channelID, message, event)  );

【参考方案2】：

您使用的是 discord.io，而不是 discord.js。

如果你想添加一个反应，你需要用这个替换你的消息事件监听器：

bot.on("message", (user, userID, channelID, message, event) => 
  bot.addReaction(
    channelID,
    messageID: event.d.id,
    reaction: "?"
  );
);

参考资料：

client.on('message', function(user, userID, channelID, message, event) ); client.addReaction( ) event.d.id
