Question

Am为一个不和谐的bot编码，如果在服务器中运行该bot可以正常工作，但是我想添加一些在DM内也可以运行的命令，我有一些为每个服务器设置前缀的代码，当我运行bot并尝试DM中的命令会产生错误，因为它正在寻找DM没有的公会ID，我该如何解决。

//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
  };
}

我尝试使用if语句，但是当我在DM中运行命令时，该命令仍然不起作用，但不会产生任何错误。

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);
  } 
}
}

下面是错误的提示，该错误将我指向我的代码中的63行

Answer 1

You can run certain things based on what type of channel it is.

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

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

All types of channels, according to the docs

dm direct message channel
group group DM channel
text server text channel
voice server voice channel
category server category channel
news server news channel
store server store channel

Answer 2

您可以使用

if(message.channel.type === 'dm') {
    let prefix = 'bot main prefix'
}
else if(message.channel.type === 'guild') {
      let prefixes = JSON.parse(fs.readFileSync("./prefixes.json", "utf8"));
}
