【中文标题】如何每天在特定时间发送消息?【英文标题】:How can I send a message every day at a specific hour? 【发布时间】:2019-05-18 03:49:15 【问题描述】:我正在尝试让机器人在特定时间编写消息。示例:
const Discord = require("discord.js");
const client = new Discord.Client();
client.on("ready", () =>
console.log("Online!");
);
var now = new Date();
var hour = now.getUTCHours();
var minute = now.getUTCMinutes();
client.on("message", (message) =>
if (hour === 10 && minute === 30)
client.channels.get("ChannelID").send("Hello World!");
);
不幸的是,它只有在我触发另一个命令时才有效,例如:
if (message.content.startsWith("!ping"))
message.channel.send("pong!");
my message: !ping (at 10:10 o'clock)
-> pong!
-> Hello World!
我猜它需要不断检查时间变量的东西。

【参考方案1】:正如 Federico 所说,这是解决这个问题的正确方法,但语法已经改变,现在随着 discord.js (v12) 的新更新,它会是这样的:
// Getting Discord.js and Cron
const Discord = require('discord.js');
const cron = require('cron');
// Creating a discord client
const client = new Discord.Client();
// We need to run it just one time and when the client is ready
// Because then it will get undefined if the client isn't ready
client.once("ready", () =>
console.log(`Online as $client.user.tag`);
let scheduledMessage = new cron.CronJob('00 30 10 * * *', () =>
// This runs every day at 10:30:00, you can do anything you want
// Specifing your guild (server) and your channel
const guild = client.guilds.cache.get('id');
const channel = guild.channels.cache.get('id');
channel.send('You message');
);
// When you want to start it, use:
scheduledMessage.start()
;
// You could also make a command to pause and resume the job
但仍然感谢 Federico,他救了我的命!

作为已接受答案的建议编辑,这可能会更好。 我无法让它工作。什么都没有发生。见***.com/questions/68490149/…【参考方案2】:我会使用cron
:使用此包,您可以设置要在日期与给定模式匹配时执行的函数。
在构建模式时,您可以使用*
表示可以使用该参数的任何值执行它,并使用范围以仅表示特定值:1-3, 7
表示您接受1, 2, 3, 7
。
这些是可能的范围:
秒:0-59
分钟:0-59
小时:0-23
日期:1-31
月份:0-11
(1 月至 12 月)
星期几:0-6
(周日至周六)
这是一个例子:
var cron = require("cron");
function test()
console.log("Action executed.");
let job1 = new cron.CronJob('01 05 01,13 * * *', test); // fires every day, at 01:05:01 and 13:05:01
let job2 = new cron.CronJob('00 00 08-16 * * 1-5', test); // fires from Monday to Friday, every hour from 8 am to 16
// To make a job start, use job.start()
job1.start();
// If you want to pause your job, use job.stop()
job1.stop();
在你的情况下,我会这样做:
const cron = require('cron');
client.on('message', ...); // You don't need to add anything to the message event listener
let scheduledMessage = new cron.CronJob('00 30 10 * * *', () =>
// This runs every day at 10:30:00, you can do anything you want
let channel = yourGuild.channels.get('id');
channel.send('You message');
);
// When you want to start it, use:
scheduledMessage.start()
// You could also make a command to pause and resume the job
