Javascript 如何为一起运行命令添加检查

我想在执行accept命令之前添加一个检查以查看是否发送了请求，我做了一些研究，以确定这是否可能，并发现您可以使用fs.writeFileSync和fs.readFileSync（）来存储和读取数据

这是主命令，我想用它发送提到的用户id，并告诉accept命令，此人确实收到了请求 （旧-这是固定的，并在下面解释）

这是accept命令，我希望它检查文件，看看他们是否收到了请求，如果没有的话，忽略这个命令。 （旧-这是固定的，并在下面解释）

这就是我得到的错误：

[ERR_INVALID_ARG_VALUE]: The argument 'true' is invalid encoding. Received 'encoding'

它说错误在第136行，这是这一行：

try {
    sentRequest == fs.readFileSync('./variable.json', variable[user].sentRequest, 'utf8') // This is line 136
} catch(err) {
    console.error(err);
} 

基本上，我能做些什么来解决这个问题，或者有更好的方法来解决这个问题

我不喜欢使用fs.read/write，因为我不想使用单独的文件来保存请求，如果可能的话，我希望所有这些都放在一个文件中

但如果这是唯一可用的东西，那么它就必须这么做

编辑：我实际上开始这样做是因为我在读取文件时遇到了问题，当文件为空或者用户没有请求时，它会崩溃，但是我添加了一个try{}，并且修复了这个问题，虽然它仍然抛出错误，但它不会崩溃，这就是我所关心的

现在无论文件中是否有人，它都无法读取该文件，它显示了上述错误。起初，我试图将其存储为bool，但由于遇到类似错误，不得不将其转换为字符串

编辑2：我想出来了。将为搜索此问题的其他人编辑此内容

GetUserFromAntify函数，如果您想使用它（我从discordjs.guide获得）：

这将生成一个名为request的新映射

这是我的新请求命令：

if (args[0] === 'request') {
    if (args[1] == null){
        return message.reply(`Hmmm... It doesnt look like you mentioned anyone... \n Try this \`${prefix}interview request @ChocolateReaper\``);
    } else if (args[1] !== null){
        if (args[1] === 'help') {
            return message.channel.send(`To send a request you must mention the user! (example: @ChocolateReaper)`);
        }
                        
        const user = getUserFromMention(args[1]);
        const author = message.author;
            
        // This checks if the command mentioned a user
        if (!user) {
            return message.reply('The user you mentioned either doesnt exist or isnt in the server, please check the spelling and try again.');
        }
        // the user.id HAS to be a string so if you need to use a variable use `` not '' or "" it's next to the 1, you cant just do let keyString = user.id it wont work
        let keyString = `${user.id}`

        // This is just for testing, it's not needed
        request.set(keyString, `${user.id}`);
        console.log('User ID: ' + request.get(keyString));
        console.log(request);
        // This is just sending the mentioned user a message telling them to accept or deny the invitation. 
        user.send(`Hello, ${user}, ${author} has requested an interview to discuss being a Content Creator with ${message.guild.name}, please reply back with an available date and time for an interview! If this date and time works with you please type $accept, if not type $deny`).catch(()=>{ console.log("I wasn't able to send the message, please try again")});
                        
        return message.channel.send(`Request Message was sent successfully to ${user.displayName}!`);
    }
}

这是我新的accept命令（注意：这只能在dm中使用，因此检查它是否在dm中）

这个错误从字面上告诉你出了什么问题？您将错误的参数传递给了

readFileSync

，请仔细阅读，然后确保您的参数顺序正确，并且包装正确。

try {
    sentRequest == fs.readFileSync('./variable.json', variable[user].sentRequest, 'utf8') // This is line 136
} catch(err) {
    console.error(err);
} 

function getUserFromMention(mention) {
    // The id is the first and only match found by the RegEx.
    const matches = mention.match(/^<@!?(\d+)>$/);

    // If supplied variable was not a mention, matches will be null instead of an array.
    if (!matches) return;

    // However the first element in the matches array will be the entire mention, not just the ID,
    // so use index 1.
    const id = matches[1];

    return client.users.cache.get(id);
}

let request = new Map()

if (args[0] === 'request') {
    if (args[1] == null){
        return message.reply(`Hmmm... It doesnt look like you mentioned anyone... \n Try this \`${prefix}interview request @ChocolateReaper\``);
    } else if (args[1] !== null){
