从一个通道记录消息

Question

我已经尝试了好几次来解决这个问题，但我不明白这个错误，我收到了，但我会解释我想做什么：基本上我想记录来自一个频道的消息，将这些消息粘贴到不同的频道。这是我到目前为止的代码；

client.on(`message`, message => {
    if (message.author.bot) return; // If the message is by a bot return.
    if (!message.guild) return; // If the message isn't in a guild return.
    if (message.guild) {
        const msgLog = `[MESSAGE] [${message.guild.name}] [#${message.channel.name}] ${message.author.username}#${message.author.discriminator}: ${message.content}\n` // You can change this to whatever you want.
        client.channels.get(`814685640088223795`).send(msgLog); // Replace CHANNEL ID with the channel ID you want the logs to go to.
        return;
    }
})

我收到的错误如下：

(node:17260) UnhandledPromiseRejectionWarning: ReferenceError: client is not defined

谢谢

Answer 1

您的索引文件中缺少此内容：

const Discord = require("discord.js");
//under const Discord etc
const client = new Discord.Client();

如果你想只允许 guildMessages，你可以这样做：

if (message.channel.type === "dm") return; //dont react to dms

最后，通过id向频道发送消息：

message.guild.channels.cache.get('814685640088223795').send(msglog); //using 'cache' since v12 uses managers

您似乎遗漏了两行重要的代码：

const Discord = require('discord.js');
const client = new Discord.Client();

在 index.js 文件的开头附加 discord.js 文档中的这两行应该可以使它起作用。
