discord.js send scheduled message
提问by Samuel Smith
Hi I've just started on Javascript and Node.js, so I don't really know what to do. Please be patient with me.Thanks!
嗨，我刚刚开始使用 Javascript 和 Node.js，所以我真的不知道该怎么做。请耐心等待我。谢谢！
So I've hosted a node.js on my physical server. I wanted to create a Discord Bot that sends a daily message on specific timings on my server, for example, I want to send a message to a channel saying "Good Morning" everyday at 8am. How do I do it?
所以我在我的物理服务器上托管了一个 node.js。我想创建一个 Discord Bot，它在我的服务器上的特定时间发送每日消息，例如，我想每天早上 8 点向频道发送一条消息，说“早安”。我该怎么做？
Currently, I only have this code to ping the bot(and the server)
目前，我只有这个代码来 ping 机器人（和服务器）
/*
A ping pong bot, whenever you send "ping", it replies "pong".
*/
// Import the discord.js module
const Discord = require('discord.js');
// Create an instance of a Discord client
const client = new Discord.Client();
// The token of your bot - https://discordapp.com/developers/applications/me
const token = 'your bot token here';
// The ready event is vital, it means that your bot will only start reacting to information
// from Discord _after_ ready is emitted
client.on('ready', () => {
console.log('I am ready!');
});
// Create an event listener for messages
client.on('message', message => {
// If the message is "ping"
if (message.content === 'ping') {
// Send "pong" to the same channel
message.channel.send('pong');
}
});
// Log our bot in
client.login(token);
Also, how do I loop this code to ensure that it sends a message everyday? Thanks in advance.
另外，我如何循环此代码以确保它每天发送一条消息？提前致谢。

so there is an answer for this:
所以有一个答案：
There are two ways to do that, with cron(or something else on different platforms) and setInterval
有两种方法可以做到这一点，使用cron（或其他平台上的其他东西）和setInterval
1) Cron
1) 定时任务
Create a new file, goodmorning.jswith this:
创建一个新文件，goodmorning.js如下：
const Discord = require('discord.js');
const client = new Discord.Client();
client.login("token").then(() => {
console.log("I am ready");
var guild = client.guilds.get('guildid');
if(guild && guild.channels.get('channelid')){
guild.channels.get('channelid').send("Good Morning").then(() => client.destroy());
} else {
console.log("nope");
//if the bot doesn't have guild with the id guildid
// or if the guild doesn't have the channel with id channelid
}
client.destroy();
});
(edit all the needed values: token, guildid and channelid)
And add a cronjob to run everyday at 8am.
This script will attempt to login into Discord and after successful login proceeds to find a guild and a channel, then just send the message, then finally logout (client.destroy()). If it wasn't found a guild or channel, just simply destroy.
（编辑所有需要的值：token、guildid 和 channelid）
并添加一个 cronjob，每天早上 8 点运行。
此脚本将尝试登录 Discord，成功登录后继续查找公会和频道，然后发送消息，最后退出 ( client.destroy())。如果没有找到公会或频道，只需将其摧毁即可。
2) setInterval
2）设置间隔
The first problem with this would be that you need to start the script at the exact time you want the code to run, or get a setTimeout to start the setInterval to repeat the code over and over.
untested but should work with possibly some tweaking needed:
第一个问题是您需要在您希望代码运行的确切时间启动脚本，或者获取 setTimeout 以启动 setInterval 以一遍又一遍地重复代码。
未经测试，但可能需要进行一些调整：
const Discord = require('discord.js');
const client = new Discord.Client();
client.on('message', message => {
//...
});
client.on('ready', () => {
setTimeout(function(){ // in leftToEight() milliseconds run this:
sendMessage(); // send the message once
var dayMillseconds = 1000 * 60 * 60 * 24;
setInterval(function(){ // repeat this every 24 hours
sendMessage();
}, dayMillseconds)
}, leftToEight())
})
function leftToEight(){
var d = new Date();
return (-d + d.setHours(8,0,0,0));
}
function sendMessage(){
var guild = client.guilds.get('guildid');
if(guild && guild.channels.get('channelid')){
guild.channels.get('channelid').send("Good Morning");
}
}
client.login("token");
I would definitely go for the cronoption, doesn't require you to have the process running all the time (unless you already have it)
我肯定会选择cron选项，不需要您一直运行该进程（除非您已经拥有它）
