如何修复 Node.JS 中的 javascript SyntaxError

Question

好的，我目前正在为我的 discord 服务器开发一个机器人。这将是一个反垃圾邮件机器人。我发现这个用 Node.JS 编写的开源简单反垃圾邮件机器人。

项目链接，有两个链接：

• https://www.npmjs.com/package/discord-anti-spam
• https://github.com/Michael-J-Scofield/discord-anti-spam

当我尝试运行 bot.js 时，我在控制台中收到此错误：

    maxDuplicatesWarning = 7,// Maximum amount of duplicate messages a user can send in a timespan before getting warned
  ^^^^^^^^^^^^^^^^^^^^^^^^

SyntaxError: Invalid shorthand property initializer
    at createScript (vm.js:80:10)
    at Object.runInThisContext (vm.js:139:10)
    at Module._compile (module.js:599:28)
    at Object.Module._extensions..js (module.js:646:10)
    at Module.load (module.js:554:32)

    at Function.Module.runMain (module.js:676:10)
    at startup (bootstrap_node.js:187:16)
    at bootstrap_node.js:608:3

我尝试删除 maxDuplicatesWarning 行，但它只是给我一个 maxDuplicatesBan 错误。

这是我的 bot.js：

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

client.on('ready', () => {
  console.log(`Bot service launched. Bot ${client.user.tag} is successfully activated!`);
client.user.setStatus("dnd");
client.user.setGame('Fidget Spinner');

var anti_spam = require("discord-anti-spam");

antispam(bot, {
  warnBuffer: 3, //Maximum amount of messages allowed to send in the interval time before getting warned.
  maxBuffer: 5, // Maximum amount of messages allowed to send in the interval time before getting banned.
  interval: 1000, // Amount of time in ms users can send a maximum of the maxBuffer variable before getting banned.
  warningMessage: "stopp å spamme eller kutter jeg av deg kuken.", // Warning message send to the user indicating they are going to fast.
  banMessage: "har blitt bannet for spamming, noen andre som vil?", // Ban message, always tags the banned user in front of it.
  maxDuplicatesWarning = 7,// Maximum amount of duplicate messages a user can send in a timespan before getting warned
  maxDuplicatesBan = 10 // Maximum amount of duplicate messages a user can send in a timespan before getting banned
});

client.login('private');

这里是 anti_spam.js：

const authors = [];
var warned = [];
var banned = [];
var messagelog = [];

/**

 * @param  {Bot} bot - The discord.js CLient/bot
 * @param  {object} options - Optional (Custom configuarion options)

 */
module.exports = function (bot, options) {
  // Set options
  const warnBuffer = (options && options.prefix) || 3;)
  const maxBuffer = (options && options.prefix) || 5;)
  const interval = (options && options.interval) || 1000;)
  const warningMessage = (options && options.warningMessage) || "stop å spamme ellers kutter jeg av deg kuken.";
  const banMessage = (options && options.banMessage) || "har blit bannet for spamming, noen andre som vil?";
  const maxDuplicatesWarning = (options && options.duplicates || 7;)
  const maxDuplicatesBan = (options && options.duplicates || 10;)

  bot.on('message', msg => {

    if(msg.author.id != bot.user.id){
      var now = Math.floor(Date.now());
      authors.push({
        "time": now,
        "author": msg.author.id

      // Check how many times the same message has been sent.
      var msgMatch = 0;
      for (var i = 0; i < messagelog.length; i++) {
        if (messagelog[i].message == msg.content && (messagelog[i].author == msg.author.id) && (msg.author.id !== bot.user.id)) {
          msgMatch++;
        }
      }
      // Check matched count
      if (msgMatch == maxDuplicatesWarning && !warned.includes(msg.author.id)) {
        warn(msg, msg.author.id);
      }
      if (msgMatch == maxDuplicatesBan && !banned.includes(msg.author.id)) {
        ban(msg, msg.author.id);
      }

      matched = 0;

      for (var i = 0; i < authors.length; i++) {

          matched++;
          if (matched == warnBuffer && !warned.includes(msg.author.id)) {
            warn(msg, msg.author.id);
          }
          else if (matched == maxBuffer) {
            if (!banned.includes(msg.author.id)) {
              ban(msg, msg.author.id);
            }
          }
        }
        else if (authors[i].time < now - interval) {
          authors.splice(i);
          warned.splice(warned.indexOf(authors[i]));
          banned.splice(warned.indexOf(authors[i]));
        }
        if (messagelog.length >= 200) {
          messagelog.shift();
        }
      }
    }
  });

  /**

   */
  function warn(msg, userid) {
    warned.push(msg.author.id);
    msg.channel.send(msg.author + " " + warningMessage);
  }

  /**
   * Ban a user by the user id
   * @param  {Object} msg

   */
  function ban(msg, userid) {
    for (var i = 0; i < messagelog.length; i++) {
      if (messagelog[i].author == msg.author.id) {
        messagelog.splice(i);

      }
    }

    banned.push(msg.author.id);

    var user = msg.channel.guild.members.find(member => member.user.id === msg.author.id);
    if (user) {
      user.ban().then((member) => {
        msg.channel.send(msg.author + " " +banMessage);
        return true;
     }).catch(() => {
        msg.channel.send("du har ikke rettigheter til å banne " + msg.author + " for spamming.");
        return false;
     });
    }
  }

}

有人可以帮我解决这个问题吗？ 谢谢：D

新更新！

现在我收到此错误：

const warnBuffer = (options && options.prefix) || 3;)
                                                      ^

Answer 1

应该是：

antispam(bot, {
  warnBuffer: 3, //Maximum amount of messages allowed to send in the interval time before getting warned.
  maxBuffer: 5, // Maximum amount of messages allowed to send in the interval time before getting banned.
  interval: 1000, // Amount of time in ms users can send a maximum of the maxBuffer variable before getting banned.
  warningMessage: "stopp å spamme eller kutter jeg av deg kuken.", // Warning message send to the user indicating they are going to fast.
  banMessage: "har blitt bannet for spamming, noen andre som vil?", // Ban message, always tags the banned user in front of it.
  maxDuplicatesWarning: 7,// Maximum amount of duplicate messages a user can send in a timespan before getting warned
  maxDuplicatesBan: 10 // Maximum amount of duplicate messages a user can send in a timespan before getting banned
});

您必须使用: 而不是= 为对象中的键赋值

更新：

client.on('ready', () => {
  console.log(`Bot service launched. Bot ${client.user.tag} is successfully activated!`)
});

尝试使用 utf-8 字符集。我在我的项目中遇到了这样的情况
