Fetch bot messages from bots Discord.js
提问by qtt qtt
I am trying to make a bot that fetches previous bot messages in the channel and then deletes them. I have this code currently that deletes all messages in the channel when !clearMessagesis entered:
我正在尝试制作一个机器人来获取频道中以前的机器人消息，然后删除它们。我目前有此代码，可在!clearMessages输入时删除频道中的所有消息：
if (message.channel.type == 'text') {
message.channel.fetchMessages().then(messages => {
message.channel.bulkDelete(messages);
messagesDeleted = messages.array().length; // number of messages deleted
// Logging the number of messages deleted on both the channel and console.
message.channel.send("Deletion of messages successful. Total messages deleted: "+messagesDeleted);
console.log('Deletion of messages successful. Total messages deleted: '+messagesDeleted)
}).catch(err => {
console.log('Error while doing Bulk Delete');
console.log(err);
});
}
I would like the bot to only fetch messages from all bot messages in that channel, and then delete those messages.
我希望机器人只从该频道中的所有机器人消息中获取消息，然后删除这些消息。
How would I do this?
我该怎么做？
回答by André Dion
Each Messagehas an authorpropertythat represents a User. Each Userhas a botpropertythat indicates if the user is a bot.
每个Message都有一个表示的author属性User。每个User都有一个bot属性来指示用户是否是机器人。
Using that information, we can filter out messages that are not bot messages with messages.filter(msg => msg.author.bot):
使用该信息，我们可以过滤掉不是机器人消息的消息messages.filter(msg => msg.author.bot)：
if (message.channel.type == 'text') {
message.channel.fetchMessages().then(messages => {
const botMessages = messages.filter(msg => msg.author.bot);
message.channel.bulkDelete(botMessages);
messagesDeleted = botMessages.array().length; // number of messages deleted
// Logging the number of messages deleted on both the channel and console.
message.channel.send("Deletion of messages successful. Total messages deleted: " + messagesDeleted);
console.log('Deletion of messages successful. Total messages deleted: ' + messagesDeleted)
}).catch(err => {
console.log('Error while doing Bulk Delete');
console.log(err);
});
}
