python - Discord Currency Bot discord.py 需要帮助

问题描述

我使用 discord.py API 用 python 制作了一个不和谐的货币机器人。但问题是当您执行 ?give {user} 时。它会起作用，但会在聊天中弹出，但在 .json 文件中，即使您执行 ?save 手动保存，金额也不会改变。我会发送代码，但我现在不在我的电脑上。因此，如果您可以解决此问题，请回复，我将向您发送我的不和谐用户。这是代码，因此您可以更好地帮助我。

bot = commands.Bot(command_prefix=commands.when_mentioned_or(f"?"),  help_command=None)

当您保存时，amounts我相信您正在保存原始变量。考虑更新您的保存功能，使其看起来像这样：

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

然后，当调用你的保存函数时

save_(amounts)

这可确保您保存的是更新后的变量，而不是最初打开的数据。

编辑：您还应该更新打开文件的方式。

def open():
    with open('amounts.json') as f:
        amounts = json.load(f)
        return amounts

然后，每当您启动命令/函数并想要访问文件的最新版本时，调用该open函数以检索该信息。

@bot.command()
async def bal(ctx):
    amounts = open()
    etc.
