问题描述

正在编写一个不和谐的机器人,如果在服务器内部运行,机器人工作正常,但我想添加一些也可以在 DM 内部工作的命令,我有一些代码为每个服务器设置前缀,当我运行机器人并在 DM 中尝试命令时它会产生错误,因为它正在寻找 DM 没有的公会 ID,我该如何解决这个问题。

//the code from line index.js:63:30 in the error message

if(message.author.bot) return;

let prefixes = JSON.parse(fs.readFileSync("./prefixes.json", "utf8"));
if(!prefixes[message.guild.id]){
  prefixes[message.guild.id] = {
    prefixes: botconfig.prefix
  };
}

我试过使用 if 语句,但是当我在 DM 中运行命令时,命令仍然不起作用,但它不会产生任何错误。

bot.on("message", async message => {
  if (message.channel.type === "dm") {
      let prefix = "!";
} else (message.guild) {
      let prefixes = JSON.parse(fs.readFileSync("./prefixes.json", "utf8"));
  if(!prefixes[message.guild.id]){
    prefixes[message.guild.id] = {
      prefixes: botconfig.prefix
    };
  let prefix = prefixes[message.guild.id].prefixes;
  if(!message.content.startsWith(prefix)) return;

    let messageArray = message.content.split(" ");
  let cmd = messageArray[0];
  let args = messageArray.slice(1);

  let commandfile = bot.commands.get(cmd.slice(prefix.length));
  if(commandfile) commandfile.run(bot,message,args);
  } 
}
}

下面是我得到的错误,它指向我的代码中的第 63 行,这是我在上面发布的代码

解决方案


你可以根据它是什么类型的通道来运行某些东西。

if (message.channel.type === 'text') {
  // Server text channel commands
}

if (message.channel.type === 'dm') {
  // DM channel commands
}

根据文档,所有类型的频道

  • dm直接消息渠道
  • group团体DM频道
  • text服务器文本通道
  • voice服务器语音通道
  • category服务器类别频道
  • news服务器新闻频道
  • store服务器存储通道
