問題描述

我希望能夠用新數據保存我的 json 文件，然后調用該數據以便我可以再次保存新數據.現在它所做的就是，當我調用 JSON 文件數據的任何部分時，我上次手動保存它時保持不變.(我確實編輯了一些代碼并更好地描述了我的問題)提前謝謝你！這是我的代碼，沒有錯誤日志:

I want to be able to save my json file with new data and then call upon that data so that I can save new data again. Right now all it is doing is it is, when I call upon any part of the JSON file's data, staying the same the last time I manually saved it. (I did edit some code and a better description of my problem) Thank you in advance! Here is my code there is no error log:

const Discord = require('discord.js');
const botconfig = require("./botconfig.json");
const fs = require("fs");
const bot = new Discord.Client();
    bot.on("message", async message => {
        let prefix = botconfig.prefix;
        let messageArray = message.content.split(" ");
        let cmd = messageArray[0];
        let args = messageArray.slice(1);
        console.log(message.member.id)
        var playerFile = require(`./playerData/${message.member.id}.json`);
        if (message.author.bot) return;
        if (message.channel.type === "dm") return;
        if (cmd.charAt(0) === prefix) {
            if(cmd === `${prefix}fc`){
                fs.exists(`./playerData/${message.member.id}.json`, function(exists) {
                    if(exists){
                    let ar = args[0];
                    let ninConsole = args[1];
                    let code = args[2];
                    if(ar === "add" || ar === "remove"){
                        if(code){
                            if(ar === "add"){
                                console.log("Add");
                                if(ninConsole === "switch"){

下面是使用 fs 將數據保存到 JSON 文件的示例:

Here is an example of saving data to a JSON file using fs:

JSON.parse(fs.readFileSync("./points.json", "utf8"));

這里有一個關于如何使用此代碼為不和諧機器人制作積分系統的示例:https://anidiotsguide_old.gitbooks.io/discord-js-bot-guide/content/coding-guides/storing-data-in-a-json-file.html

There is an example on how to use this code to make a points system for a discord bot here: https://anidiotsguide_old.gitbooks.io/discord-js-bot-guide/content/coding-guides/storing-data-in-a-json-file.html

下面是這個例子的代碼:

Here is the code for this example:

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

let points = JSON.parse(fs.readFileSync("./points.json", "utf8"));
const prefix = "+";

client.on("message", message => {
  if (!message.content.startsWith(prefix)) return;
  if (message.author.bot) return;

  if (!points[message.author.id]) points[message.author.id] = {
    points: 0,
    level: 0
  };
  let userData = points[message.author.id];
  userData.points++;

  let curLevel = Math.floor(0.1 * Math.sqrt(userData.points));
  if (curLevel > userData.level) {
    // Level up!
    userData.level = curLevel;
    message.reply(`You"ve leveled up to level **${curLevel}**! Ain"t that dandy?`);
  }

  if (message.content.startsWith(prefix + "level")) {
    message.reply(`You are currently level ${userData.level}, with ${userData.points} points.`);
  }
  fs.writeFile("./points.json", JSON.stringify(points), (err) => {
    if (err) console.error(err)
  });

});

client.login("SuperSecretBotTokenHere");

我希望這會有所幫助！

這篇關于保存 JSON 文件以便稍后從中獲取其他數據的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網！
