【中文标题】无法使用 Discord.js 在数据库中写入和读取值

【英文标题】：Unable to write and read values in a database, using Discord.js

【发布时间】：2022-01-24 04:37:15

【问题描述】：

我试图让员工使用~reply <message> 而不是~dm <userID> <message> 回复最后一个 DM，但首先，我必须将用户的 ID 保存在数据库中才能知道谁是最后一个 DM 用户，但我在这里遇到一个错误，我很困惑为什么会发生这种情况，但请注意，我对数据库真的很陌生，我会寻求一些帮助！

我的代码（不是全部，只是我用于命令的代码。）：

我在错误所在的行之前添加了“>>”。

const  Client, Collection, Intents, MessageEmbed  = require('discord.js');
const client = new Client(partials: ['MESSAGE', 'CHANNEL', 'REACTION'], ws:  intents: Intents.ALL  );
const Database = require('@replit/database');
const db = new Database();

client.on('message', async message => 
    
  //Dm checker

  if (message.channel.type === 'dm') 

>>  let lastDM = await db.get(`dm_$message.author.id`)

    if (lastDM === null) lastDm = `dm_NONE`

    if (message.author.id == client.user.id) return;
    if (message.author.id == '818749579369512978') return message.channel.send("This chat has been Blacklisted by the developer (<@"+ BOT_OWNER +">)");
    const embed1 = new MessageEmbed()
      .setTitle("New message!")
      .setAuthor(`Name: \`$message.author.username\` ID: \`$message.author.id\` `)
      .setColor("GRAY")
      .setFooter("Dm message")
      .addField("Message:", `\`\`\`$message.content\`\`\``, false);
    const embed2 = new MessageEmbed()
      .setTitle("New reply!")
      .setAuthor(`Name: \`$message.author.username\` ID: \`$message.author.id\` `)
      .setColor("GRAY")
      .setFooter("Dm reply")
      .addField("Reply:", `\`\`\`$message.content\`\`\``, false);
    if (lastDM === `dm_$message.author.id`) 
        client.channels.cache.get("920895881656532992").send(`You got a reply!`, embed2)
        console.log(lastDM)
       else 
        await db.set(`dm_$message.author.id`).then(
          client.channels.cache.get("920895881656532992").send(`I was DMed!`, embed1),
          console.log(lastDM)
        )
      
    

错误：

(node:703) UnhandledPromiseRejectionWarning: SyntaxError: Failed to parse value of dm_612110791683866644, try passing a raw option to get the raw value

注意：我使用的是replit's 数据库。

【参考方案1】：

我正在回答我自己的问题，因为我找到了一种方法，但我仍然不明白错误是什么，因为其他任何东西都可以正常工作，无论如何，我很快意识到我的代码真的没有，所以我修复了它，这是代码：

const  MessageEmbed  = require('discord.js');
const Database = require('@replit/database');
const db = new Database();

client.on('message', async message => 
    
  //Dm checker

  if (message.channel.type === 'dm') 

    let lastDM = await db.get(`lastDM`)

    if (!lastDM) lastDM = `NONE`

    if (message.author.id == client.user.id) return;
    if (message.author.id == '818749579369512978') return message.channel.send("This chat has been Blacklisted by the developer (<@"+ BOT_OWNER +">)");
    const embed = new MessageEmbed()
      .setTitle("New message!")
      .setAuthor(`Name: \`$message.author.username\` ID: \`$message.author.id\` `)
      .setColor("GRAY")
      .setFooter("Dm message")
      .addField("Message:", `\`\`\`$message.content\`\`\``, false);
    await db.set(`lastDM`, message.author.id).then(
      client.channels.cache.get("920895881656532992").send(`Someone messaged me.`, embed),
      console.log(lastDM)
    )
  

并回复命令：

const  MessageEmbed  = require('discord.js');
const Database = require('@replit/database');
const db = new Database();

module.exports = 
    name: 'reply',
    category: 'Owner',
    description: 'Replys to last DM.',
    aliases: [],
    usage: 'Reply <message>',
    userperms: ['BOT_OWNER'],
    botperms: [],
    run: async (client, message, args) => 

    if (message.author.bot) return;

    let lastDM = await db.get(`lastDM`);
    let msg = args.slice(0).join(' ')

    if (!lastDM) return message.channel.send("There was no any resent DMs.")
    if (!msg) return message.channel.send("I can't send air, please state a message.")

    if (!isNaN(lastDM)) 
      client.users.cache.get(lastDM).send(msg)
      .catch (err => 
        return message.channel.send("Failed to send DM, as the user has blocked me or they have DMs closed!")
      )
    
  

我希望我能以某种方式帮助使用 replit 数据库的人
