Question

因此，我正在使用我在源代码浏览器中找到的这段代码与我的机器人在Discord上实施其fortnite命令。运行后，它显示：

(node:11358) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'toLowerCase' of undefined

const Discord = require("discord.js");
const Client = require('fortnite');
const fortnite = new Client(`config.TRN_API_KEY`);

module.exports.run = async(bot, message, args) => {
  let username = args[0];
  let platform = args[1];

  if (!username) return message.channel.send("Please, provide a users nickname!(Fortnite)")
  if (!platform) return message.channel.send("Did you provide a platform ? Proper usage : ** ? fortnite < username > < platform > ** ")

  let data = fortnite.user(username, platform).then(data => {
    let stats = data.stats;
    let lifetime = stats.lifetime;

    let score = lifetime[6]['Score'];
    let mplayed = lifetime[7]['Matches Played'];
    let wins = lifetime[8]['Wins'];
    let winper = lifetime[9]['Win%'];
    let kills = lifetime[10]['Kills'];
    let kd = lifetime[11]['K/d'];
    let embed = new Discord.RichEmbed()
      .setTitle("Lifetime Stats")
      .setAuthor(data.username)
      .setColor("RANDOM")
      .addField("Wins", wins, true)
      .addField("Kills", kills, true)
      .addField("Score", score, true)
      .addField("Matches Played", mplayed, true)
      .addField("Win%", winper, true)
      .addField("K/D", kd, true)
      .setTimestamp()
      .setFooter("Requested By " + message.author.tag, message.author.avatarURL);

    message.channel.send(embed);
  }).catch((err) => {
    message.channel.send('User not found!');
    console.error(err);
  });
}

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

我真的只是想找出问题所在。我的直觉说这是user.js的问题，但我可能错了。我所知道的是，当我想要它时它不起作用。这是一个命令脚本，我从Source Code Explorer（源代码资源管理器）获得，只是想亲自尝试一下，但始终遇到.toLowerCase错误。如您所见，此脚本中甚至都没有定义它。我该怎么办？

这是user.js脚本的代码：

const Mode = require('./Mode');
const Stat = require('./Stat');

/** Class representing a full user */
class User {
  /**
   * @param {Object} data All of the data resolved from the API
   */
  constructor(data) {
    this.id = data.accountId;
    this.username = data.epicUserHandle;
    this.platform = data.platformNameLong;
    this.url = `https://fortnitetracker.com/profile/${data.platformName.toLowerCase()}/${this.username}`;
    this.stats = {};

    for (const mode in data.stats) {
      // Replace the playlist id with its name for the keys
      this.stats[modes[mode]] = new Mode(data.stats[mode]);
    }

    // TODO: Make lifetime single objects and not an array
    // Will be updated in a newer version
    this.stats.lifetime = data.lifeTimeStats.map(stat => new Stat(stat));
  }
}

const modes = {
  p2: 'solo',
  p10: 'duo',
  p9: 'squad',
  curr_p2: 'current_solo',
  curr_p10: 'current_duo',
  curr_p9: 'current_squad'
};

module.exports = User;

因此，这是我的问题的更新和修复。他们最终给我发送了一封电子邮件，说他们已经解决了一些问题，并重新生成了令牌并重试。代码完美运行。感谢大家的帮助，我非常感谢。

Answer 2

我不确定 .toLowerCase 在哪里，但根据事实判断，如果你写了 .toLowerCase，我会告诉你这是错误的。 toLowerCase 是一个函数，而不是一个属性。每当你做 .toLowerCase() <-- 看到括号了吗？这就是定义任何函数的方式。但是您使用的是类，所以我想您也知道这一点

TypeError：无法读取属性“ toLowerCase”
