如何获取启动文件中的客户端对象？

Question

我有一个 Discord Bot，现在需要分片。我创建了一个名为“botlaunch.js”的文件，我从控制台 (pm2 start botlaunch.js) 开始。此文件中包含分片所需的所有内容。

这是我的 botlaunch.js 的样子：

const Discord = require('discord.js');
const settings = require('./settings.json');
const chalk = require('chalk');

const shardingManager = new Discord.ShardingManager('./lenoxbot.js',
        {
            token: settings.token
        });


    shardingManager.spawn('auto', 500).then(() => {
        console.log(chalk.green(`[ShardManager] Started ${shardingManager.totalShards} shards`));
    }).catch(error => {
        console.log(error);
    });

我需要在这段代码之后访问客户端对象。我用下面的函数试过了，但是这个也不起作用。没有错误或类似的东西，它只是 returns undefined 对于我要求的一切，无关紧要：

function exec(script) {
            let requestId = 0;
            const currentRequestId = requestId++;

            process.send({ cmd: 'exec', script: script, reqId: currentRequestId });

            const promiseExec = new Promise(resolve => {
                _promiseQueue[currentRequestId] = resolve;
            });
            const promiseTimer = new Promise((resolve, reject) => {
                setTimeout(() => {
                    reject('Promise timed out before completion @ LenoxBotLauncher/exec');
                }, 60 * 1000);
                _promiseQueue.delete(currentRequestId);
            });

            return Promise.race([promiseExec, promiseTimer]);
        }

关于我如何使用我的 botlaunch.js 代码下的客户端，您有什么解决方案吗？

Answer 1

您可以像这样使用 ShardingManager#broadcastEval() if you want to obviously eval something, if you need some properties use ShardingManager#fetchClientValues()：

shardingManager.fetchClientValues('guilds.size')
.then(results => {
    console.log(`${results.reduce((prev, guildCount) => prev + guildCount, 0)} total guilds`);
})
.catch(console.error);

如果你想从机器人内部broadcastEval/fetchClientValues，你可以使用client.shard.fetchClientValues()/client.shard.broadcastEval()

这里还有一个很好的指南：https://discordjs.guide/sharding/#broadcasteval

另一种方法是使用 2 个客户端而不是 ShardingManager，例如：

const client1 = new Discord.Client({ shardId: 0, shardCount: 2});
const client2 = new Discord.Client({ shardId: 1, shardCount: 2});

This would mean that the bot will run in 1 process only and this might cause performance issues.
