Discord.js sending a message in 1 minute intervals
提问by fragile
Hello I'm trying to send out an automated message to discord but I keep getting the following error:
您好，我正在尝试向不和谐发送自动消息，但我不断收到以下错误：
bot.sendMessage is not a function
I'm unsure as to why I'm getting this error, below is my code;
我不确定为什么我会收到这个错误，下面是我的代码；
var Discord = require('discord.js');
var bot = new Discord.Client()
bot.on('ready', function() {
console.log(bot.user.username);
});
bot.on('message', function() {
if (message.content === "$loop") {
var interval = setInterval (function () {
bot.sendMessage(message.channel, "123")
}, 1 * 1000);
}
});

Lennart is correct, you can't use bot.sendMessagebecause botis a Clientclass, and doesn't have the sendMessagefunction. That's the tip of the iceberg. What you're looking for is send(or the old version, sendMessage).
Lennart 是正确的，您不能使用，bot.sendMessage因为bot是一个Client类，并且没有该sendMessage功能。这就是冰山一角。您正在寻找的是send（或旧版本，sendMessage）。
These functions can't be used directly from the ClientClass (which is what botis, they are used on a TextChannelclass. So how do you get this TextChannel? You get it fromthe Messageclass. In your sample code, you aren't actually getting a Messageobject from your bot.on('message'...listener, but you should!
这些函数不能直接从ClientClass 中使用（也就是说bot，它们被用在一个TextChannel类上。那么你怎么得到这个TextChannel？你从这个Message类中得到它。在你的示例代码中，你实际上并没有得到一个Message来自你的bot.on('message'...听众的反对，但你应该！
The callback function to bot.on('...should look something like this:
to 的回调函数bot.on('...应该是这样的：
// add message as a parameter to your callback function
bot.on('message', function(message) {
// Now, you can use the message variable inside
if (message.content === "$loop") {
var interval = setInterval (function () {
// use the message's channel (TextChannel) to send a new message
message.channel.send("123")
.catch(console.error); // add error handling here
}, 1 * 1000);
}
});
You'll also notice I added .catch(console.error);after using message.channel.send("123")because Discord expects their Promise-returning functions to handle errors.
您还会注意到我.catch(console.error);在使用后添加了，message.channel.send("123")因为 Discord 期望它们的Promise返回函数来处理错误。
I hope this helps!
我希望这有帮助！

Your code is returning the error, because Discord.Client()doesn't have a method called sendMessage()as can be seen in the docs.
您的代码正在返回错误，因为Discord.Client()没有sendMessage()可以在docs 中看到的调用方法。
If you would like to send a message, you should do it in the following way;
如果您想发送消息，您应该通过以下方式进行；
var Discord = require('discord.js');
var bot = new Discord.Client()
bot.on('ready', function() {
console.log(bot.user.username);
});
bot.on('message', function() {
if (message.content === "$loop") {
var interval = setInterval (function () {
message.channel.send("123")
}, 1 * 1000);
}
});
I recommend familiarising yourself with the documentation for discord.js which can be found here.
我建议您熟悉 discord.js 的文档，可以在此处找到。
