在 JavaScript Discord Bot 中，为什么 message.react() 是 "not a function"

Question

我正在运行我的服务器上安装一个 discord 机器人。我想让机器人 message.react() 收到我刚收到的消息。当我运行它工作正常，直到我发送一条消息。

我收到这个错误：

/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.ontext (/Users/revel/Projects/Discord/DiscordBot/node_modules/ws/lib/WebSocket.js:841:10)

    at Receiver.flush (/Users/revel/Projects/Discord/DiscordBot/node_modules/ws/lib/Receiver.js:347:3)
    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("");
});

我是运行宁discord.js版12.2.0你能帮忙吗？

Answer 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 link :

中所述

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

Answer 2

您正在使用 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: ""
  });
});
