python - Discord 金钱机器人将用户 ID 保存在 json 文件中。当 Not 重新启动时，它会为每个人创建一个新的(但相同的)ID

Question

当这段代码运行时，它可以从discord中获取用户ID，并将他们有100 block 钱放入json中，但是一旦你重新启动机器人，你就必须再次注册，它会在json文件中写入相同的用户ID，认为这是一个新用户，当它不是时。

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")

机器人关闭并重新打开并注册两次后的 JSON(虚假用户 ID):

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

即使在机器人关闭并重新打开后，也需要它能够识别用户 ID。

发生这种情况是因为 JSON 对象始终具有“键”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执行相同的操作。

from discord.ext import commands

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()
