node.js 删除 discord.js 文本通道中的所有消息

Deleting all messages in discord.js text channel

提问by Xydez

Ok, so I searched for a while, but I couldn't find any information on how to delete all messages in a discord channel. And by all messages I mean every single message ever written in that channel. Any clues?

好的，所以我搜索了一段时间，但找不到有关如何删除不和谐频道中所有消息的任何信息。我所说的所有消息是指在该频道中写入的每条消息。有什么线索吗？

Try this

尝试这个

async () => {
  let fetched;
  do {
    fetched = await channel.fetchMessages({limit: 100});
    message.channel.bulkDelete(fetched);
  }
  while(fetched.size >= 2);
}

Discord does not allow bots to delete more than 100 messages, so you can't delete every message in a channel. You can delete less then 100 messages, using BulkDelete.

Discord 不允许机器人删除超过 100 条消息，因此您无法删除频道中的每条消息。您可以使用 BulkDelete 删除少于 100 条消息。

Example:

例子：

const Discord = require("discord.js");
const client = new Discord.Client();
const prefix = "!";

client.on("ready" () => {
    console.log("Successfully logged into client.");
});

client.on("message", msg => {
    if (msg.content.toLowerCase().startsWith(prefix + "clearchat")) {
        async function clear() {
            msg.delete();
            const fetched = await msg.channel.fetchMessages({limit: 99});
            msg.channel.bulkDelete(fetched);
        }
        clear();
    }
});

client.login("BOT_TOKEN");

Note, it has to be in a async function for the awaitto work.

请注意，它必须在异步函数中才能等待工作。

Here's my improved version that is quicker and lets you know when its done in the console but you'll have to run it for each username that you used in a channel (if you changed your username at some point):

这是我的改进版本，它更快，并让您知道何时在控制台中完成，但您必须为您在频道中使用的每个用户名运行它（如果您在某个时候更改了用户名）：

// Turn on Developer Mode under User Settings > Appearance > Developer Mode (at the bottom)
// Then open the channel you wish to delete all of the messages (could be a DM) and click the three dots on the far right.
// Click "Copy ID" and paste that instead of LAST_MESSAGE_ID.
// Copy / paste the below script into the JavaScript console.

var before = 'LAST_MESSAGE_ID';
var your_username = ''; //your username
var your_discriminator = ''; //that 4 digit code e.g. username#1234
var foundMessages = false;
clearMessages = function(){
    const authToken = document.body.appendChild(document.createElement`iframe`).contentWindow.localStorage.token.replace(/"/g, "");
    const channel = window.location.href.split('/').pop();
    const baseURL = `https://discordapp.com/api/channels/${channel}/messages`;
    const headers = {"Authorization": authToken };

    let clock = 0;
    let interval = 500;

    function delay(duration) {
          return new Promise((resolve, reject) => {
              setTimeout(() => resolve(), duration);
          });
    }

    fetch(baseURL + '?before=' + before + '&limit=100', {headers})
    .then(resp => resp.json())
    .then(messages => {
        return Promise.all(messages.map((message) => {
            before = message.id;
            foundMessages = true;

            if (
                message.author.username == your_username
                && message.author.discriminator == your_discriminator
            ) {
                return delay(clock += interval).then(() => fetch(`${baseURL}/${message.id}`, {headers, method: 'DELETE'}));
            }
        }));
    }).then(() => {

        if (foundMessages) {
            foundMessages = false;
            clearMessages();
        } else {
            console.log('DONE CHECKING CHANNEL!!!')
        }

    });
}
clearMessages();

The previous script I found for deleting your own messages without a bot...

我发现的上一个脚本用于在没有机器人的情况下删除您自己的消息......

// Turn on Developer Mode under User Settings > Appearance > Developer Mode (at the bottom)
// Then open the channel you wish to delete all of the messages (could be a DM) and click the three dots on the far right.
// Click "Copy ID" and paste that instead of LAST_MESSAGE_ID.
// Copy / paste the below script into the JavaScript console.
// If you're in a DM you will receive a 403 error for every message the other user sent (you don't have permission to delete their messages).

var before = 'LAST_MESSAGE_ID';
clearMessages = function(){
    const authToken = document.body.appendChild(document.createElement`iframe`).contentWindow.localStorage.token.replace(/"/g, "");
    const channel = window.location.href.split('/').pop();
    const baseURL = `https://discordapp.com/api/channels/${channel}/messages`;
    const headers = {"Authorization": authToken };

    let clock = 0;
    let interval = 500;

    function delay(duration) {
        return new Promise((resolve, reject) => {
            setTimeout(() => resolve(), duration);
        });
    }

    fetch(baseURL + '?before=' + before + '&limit=100', {headers})
        .then(resp => resp.json())
        .then(messages => {
        return Promise.all(messages.map((message) => {
            before = message.id;
            return delay(clock += interval).then(() => fetch(`${baseURL}/${message.id}`, {headers, method: 'DELETE'}));
        }));
    }).then(() => clearMessages());
}
clearMessages();
