Discord money机器人将用户ID保留在json文件中.当Bot重新启动时，它将为每个人创建一个新的(但相同的)ID [英] Discord money bot keeping user ID's in json file. When Bot restarts it creats a new (but same) ID for everyone

问题描述

运行此代码时，它可以从不和谐中获取用户ID，并将他们的json存入100美元，但是一旦您重新启动bot，就必须再次注册，并在json文件中写入相同的用户ID，以为这是一个不是新用户.

When this code runs it works getting the user ID from discord and putting they have 100 money in the json, but once you restart the bot you have to register again and it writes the same user ID in the json file thinking it's a new user when it is not.

from discord.ext import commands
import discord
import json

bot = commands.Bot('!')

amounts = {}

@bot.event
async def on_ready():
    global amounts
    try:
        with open('amounts.json') as f:
            amounts = json.load(f)
    except FileNotFoundError:
        print("Could not load amounts.json")
        amounts = {}

@bot.command(pass_context=True)
async def balance(ctx):
    id = ctx.message.author.id
    if id in amounts:
        await ctx.send("You have {} in the bank".format(amounts[id]))
    else:
        await ctx.send("You do not have an account")

@bot.command(pass_context=True)
async def register(ctx):
    id = ctx.message.author.id
    if id not in amounts:
        amounts[id] = 100
        await ctx.send("You are now registered")
        _save()
    else:
        await ctx.send("You already have an account")

@bot.command(pass_context=True)
async def transfer(ctx, amount: int, other: discord.Member):
    primary_id = ctx.message.author.id
    other_id = other.id
    if primary_id not in amounts:
        await ctx.send("You do not have an account")
    elif other_id not in amounts:
        await ctx.send("The other party does not have an account")
    elif amounts[primary_id] < amount:
        await ctx.send("You cannot afford this transaction")
    else:
        amounts[primary_id] -= amount
        amounts[other_id] += amount
        await ctx.send("Transaction complete")
    _save()

def _save():
    with open('amounts.json', 'w+') as f:
        json.dump(amounts, f)

@bot.command()
async def save():
    _save()

bot.run("Token")

关闭僵尸程序然后重新打开并注册两次(伪造的用户ID)后的JSON:

JSON after the bot is turned off and back on and registered twice (fake user IDs):

{"56789045678956789": 100, "56789045678956789": 100}

即使在关闭并重新打开漫游器后也需要能够识别用户ID.

Need it to be able to recognize the user IDs even after the bot is turned off and back on.

推荐答案

之所以会这样，是因为JSON对象始终具有用于键"的字符串.因此，json.dump将整数键转换为字符串.您可以通过在使用用户ID之前将其转换为字符串来完成相同的操作.

This is happening because JSON objects always have strings for the "keys". So json.dump converts the integer keys to strings. You can do the same by converting the user ids to strings before you use them.

from discord.ext import commands
import discord
import json

bot = commands.Bot('!')

amounts = {}

@bot.event
async def on_ready():
    global amounts
    try:
        with open('amounts.json') as f:
            amounts = json.load(f)
    except FileNotFoundError:
        print("Could not load amounts.json")
        amounts = {}

@bot.command(pass_context=True)
async def balance(ctx):
    id = str(ctx.message.author.id)
    if id in amounts:
        await ctx.send("You have {} in the bank".format(amounts[id]))
    else:
        await ctx.send("You do not have an account")

@bot.command(pass_context=True)
async def register(ctx):
    id = str(ctx.message.author.id)
    if id not in amounts:
        amounts[id] = 100
        await ctx.send("You are now registered")
        _save()
    else:
        await ctx.send("You already have an account")

@bot.command(pass_context=True)
async def transfer(ctx, amount: int, other: discord.Member):
    primary_id = str(ctx.message.author.id)
    other_id = str(other.id)
    if primary_id not in amounts:
        await ctx.send("You do not have an account")
    elif other_id not in amounts:
        await ctx.send("The other party does not have an account")
    elif amounts[primary_id] < amount:
        await ctx.send("You cannot afford this transaction")
    else:
        amounts[primary_id] -= amount
        amounts[other_id] += amount
        await ctx.send("Transaction complete")
    _save()

def _save():
    with open('amounts.json', 'w+') as f:
        json.dump(amounts, f)

@bot.command()
async def save():
    _save()

bot.run("Token")
