Discord Bot Maker - MySQL 调平系统或 Discord.js - MySQL 调平系统答案

【问题描述】：

所以让我来布置背景：

不和谐机器人制造商：我有一个调平系统，可以根据帖子添加 xp 并将其存储到 JSON 文件中，并且可以正常工作。一旦成员达到一定的经验等级，机器人就会在不和谐中为他们分配一个新角色。如果我必须重新启动机器人，所有拥有 xp 的成员都会从 0 xp 的级别 1 重新开始。

Discord.js 我有一个 xp 机器人，它根据帖子添加 xp 并将信息存储在在线 MySQL 数据库中。此机器人在达到特定 xp 级别时不会自动分配角色，但如果我需要重新启动机器人，则会保存信息。

我需要帮助（指向正确的方向）让 DBM 机器人将数据存储在 MySQL 中（我已经搜索了几个小时，但找不到教程或任何东西）。这是 DBM 原始数据（减去 ID 和其他不相关的信息）

我需要弄清楚当存储在 MySQL 中的 xp 达到一定级别时，如何让 discord.js 机器人向成员添加角色。这是 discord.js 机器人代码（同样删除了登录信息）：

./bot.js

    const Discord = require('discord.js');
    const bot = new Discord.Client();
    const mysql = require("mysql");
    const prefix = '.';
    const fs = require('fs');
    
    bot.commands = new Discord.Collection();
    
    
    fs.readdir("./cmds/", (err, files) => {
      if(err) console.error(err);
    
      let jsfiles = files.filter(f => f.split(".").pop() === "js");
      if(jsfiles.length <= 0) {
        console.log("No commands to load!");
        return;
      }
    
      console.log(`Loading ${jsfiles.length} commands!`);
    
      jsfiles.forEach((f, i) => {
        let props = require(`./cmds/${f}`);
        console.log(`${i + 1}: ${f} loaded!`);
        bot.commands.set(props.help.name, props);
      });
    });
    
    bot.login(process.env.BOT_TOKEN);
    
    bot.once('ready', () => {
        console.log('Bot is online!')
    });
    
    var con =mysql.createConnection({
        host: "host name goes here",
        user: "username goes here",
        password: "password goes here",
        database: "database name goes here"
    });
    
    con.connect(err => {
      if(err) throw err;
      console.log("Connected to database.");
      
    });
    
    function generateXp() {
      let min = 1
      let max = 1
    //the above numbers are both one's because I only want each message to count as 1xp
      return Math.floor(Math.random() * (max - min + 1)) + min;
    };
    
    bot.on('message', async message => {
      if(message.author.bot) return;
      if(message.channel.type === "dm") return;
    
      con.query(`SELECT * FROM xp WHERE id = '${message.author.id}'`, (err, rows) => {
        if (err) throw err;
        
        let sql;
    
        if(rows.length < 1) {
          sql = `INSERT INTO xp (id, xp) VALUES ('${message.author.id}', ${generateXp()})`
        } else {
            let xp = rows[0].xp;
            sql = `UPDATE xp SET xp = ${xp +generateXp()} WHERE id = '${message.author.id}'`;
        }
    
        con.query(sql);
    
      });
    
      if(/(?:https?:\/)?discord(?:app.com\/invite|.gg)/gi.test(message.content)) {
        message.delete();
        return;
      }
    
      let messageArray = message.content.split(/\s+/g);
      let command = messageArray[0];
      let args = messageArray.slice(1);
    
      if(!command.startsWith(prefix)) return;
    
      let cmd = bot.commands.get(command.slice(prefix.length));
      if(cmd) cmd.run(bot, message, args, con);
    
    });

./cmds/xp.js

    module.exports.run = async (bot, message, args, con) => {
        let target = message.mentions.users.first() || message.author;
    
        con.query(`SELECT * FROM xp WHERE id = '${target.id}'`, (err, rows) => {
            if(err) throw err;
    
            if(!rows[0]) return message.channel.send("This member has no XP on record.")
            let xp = rows[0].xp;
            message.channel.send(xp);
        });
    };
    
    module.exports.help = {
        name: "xp"
    }

【问题讨论】：

这是一个小细节，但在您的代码 sn-ps 中突出显示的语法似乎有点不对劲。您可以像这样在初始反引号之后添加语言：```javascript

【解决方案1】：

我在 Discord Bot Maker 方面没有太多经验，但我可以为 discord.js 提供一个潜在的解决方案。 Its documentation 可能需要一些时间来适应，但它做得很好，对于找到你需要的东西很有用。

在您的主消息事件处理程序中，运行更新他们的经验值 (con.query(sql)) 的 SQL 查询后，您应该检查他们的经验值是否超过了该角色的阈值。

// inside the callback for your SELECT query
if (err) throw err;

let sql;
let originalXp;
let updatedXp;

if (rows.length < 1) {
  originalXp = 0;
  updatedXp = generateXp();
  sql = `INSERT INTO xp (id, xp) VALUES ('${message.author.id}', ${updatedXp})`;
} else {
  originalXp = rows[0].xp;
  updatedXp = originalXp + generateXp();
  sql = `UPDATE xp SET xp = ${updatedXp} WHERE id = '${message.author.id}'`;
}

con.query(sql);

// if you want different roles at certain thresholds, replace this with the snippet later in the answer
if (originalXp < SOME_XP_THRESHOLD && updatedXp >= SOME_XP_THRESHOLD) {
  // this example gets a role based on name
  // you could also get the role you want using some other criteria
  const role = message.member.guild.roles.cache.find(role => role.name === ROLE_TO_ADD);
  message.member.roles.add(role);
}

如果你想包含多个角色来达到不同的阈值，你可以将它们设置在一个数组中：

const roles = [
  {
    name: 'foo',
    threshold: 5,
  },
  {
    name: 'bar',
    threshold: 10,
  },
];

然后循环遍历它们：

// insert this snippet instead at the point indicated above
for (const xpRole of roles) {
  if (originalXp < xpRole.threshold && updatedXp >= xpRole.threshold) {
    const role = message.member.guild.roles.cache.find(role => role.name === xpRole.name);
    // you could potentially remove the previous role here as well
    message.member.roles.add(role);
  }
}
