Question

问题是我试图创建一个显示用户拥有多少硬币的命令，但是每次我键入命令时，它只会返回“无法读取未定义的属性” id”。

代码如下：

const Discord = require("discord.js");
let coins = require("../coins.json");

module.exports.run = async (bot, message, args) => {
  //!coins
    let pUser = message.guild.member(message.mentions.users.first()) || message.guild.members.get(args[0]);
    if(!coins[pUser.id]){
    coins[pUser.id] = {
      coins: 0
    };
  }

    if(!coins[message.author.id]){
    coins[message.author.id] = {
      coins: 0
    };
  }

  let pCoins = coins[pUser.id].coins;
  let uCoins = coins[message.author.id].coins;


  if (!pUser) { 
      message.channel.send(`**${message.author}**: Ai manglit **${uCoins}** puncte de neață!`);
  } else {
      message.channel.send(`**${pUser}**: Ai manglit **${pCoins}** puncte de neață!`);
    }
}

module.exports.help = {
  name: "neti"
}

这也是我的coin.json文件：

{
   "108225935509057536":{
      "coins":3,
      "id":"108225935509057536"

Answer 1

此块将始终是未定义的，pUser是guild.member，并且没有属性id

if(!coins[pUser.id]){
  coins[pUser.id] = {
    coins: 0
  };
}

此代码的第一部分将返回message.author的集合，因此您将看到[object，object]

if (!pUser) { 
  message.channel.send(`**${message.author}**: Ai manglit **${uCoins}** puncte de neață!`);
} else {
  message.channel.send(`**${pUser}**: Ai manglit **${pCoins}** puncte de neață!`);
}

正确的方法是：

const Discord = require("discord.js");
let coins = require("../coins.json");

module.exports.run = async (bot, message, args) => {
  let targetMember = message.guild.member(message.mentions.users.first()) || message.guild.members.get(args[0])
  if(!targetMember) targetMember = message.member

  if(!coins[targetMember.user.id]){
    coins[targetMember.user.id] = {
      coins: 0
    };
  }

  let pCoins = coins[targetMember.user.id].coins;

  message.channel.send(`**${targetMember.user.id}**: Ai manglit **${pCoins}** puncte de neață!`);
}

module.exports.help = {
  name: "neti"
}

Answer 2

实际上，在您的代码中，您得到的用户是被提及的用户，或者如果您在第一个arg中键入ID的用户，则得到的用户

/ coin @ john＃0000或/ coin 192367487362（这是一个示例）

您必须添加一个条件来保护您的代码免遭诸如此类的错误：

module.exports.run = async (bot, message, args) => {
  //!coins
    let pUser = message.guild.member(message.mentions.users.first()) || message.guild.members.get(args[0]);

    if(!pUser) {
      // Do something if no user was mentionned and no id was sent with the first argument
      return;
    }

    if(!coins[pUser.id]){
    coins[pUser.id] = {
      coins: 0
    };
  }

    if(!coins[message.author.id]){
    coins[message.author.id] = {
      coins: 0
    };
  }

  let pCoins = coins[pUser.id].coins;
  let uCoins = coins[message.author.id].coins;


  if (!pUser) { 
      message.channel.send(`**${message.author}**: Ai manglit **${uCoins}** puncte de neață!`);
  } else {
      message.channel.send(`**${pUser}**: Ai manglit **${pCoins}** puncte de neață!`);
    }
}

Answer 3

const data = {“ 108225935509057536”：{硬币：3，编号：“ 108225935509057536”}};

console.log（data [“ 108225935509057536”]）;

尝试

无法读取未定义的属性“ id”
