体验（XP）不适用于所有用户 JSON Discord.PY

我试图为在大约有 50-60 人打字的房间中输入的消息评分。它会第一次将用户添加到 JSON 文件，但不会为他们键入的消息添加任何更多点。我再次测试，只有一名用户因输入的消息而获得积分，其余的保持不变。这是代码：

 @client.event
async def on_message(message):

    if message.content.lower().startswith('!points'):
        await client.send_message(message.channel, "You have {} points!".format(get_points(message.author.id)))

    user_add_points(message.author.id,1)

def user_add_points(user_id: int, points: int):
    if os.path.isfile("users.json"):
        try: 
            with open('users.json', 'r') as fp:
                users = json.load(fp)
            users[user_id]['points'] += points
            with open('users.json', 'w') as fp:
                json.dump(users, fp, sort_keys=True, indent=4)
        except KeyError:
            with open('users.json', 'r') as fp:
                users = json.load(fp)
            users[user_id] = {}
            users[user_id]['points'] = points
            with open('users.json', 'w') as fp:
                json.dump(users, fp, sort_keys=True, indent = 4)
    else:
        users = {user_id:{}}
        users[user_id]['points'] = points
        with open('users.json', 'w') as fp:
            json.dump(users, fp, sort_keys=True, indent=4)

def get_points(user_id: int):
    if os.path.isfile('users.json'):
        with open('users.json', 'r') as fp:
            users = json.load(fp)
        return users[user_id]['points']
    else:
        return 0

我们应该只需要读取该文件一次，然后在需要时保存对文件的修改。我没有注意到任何会导致所描述的行为的逻辑错误，因此这可能是关于允许您的机器人查看哪些消息的权限问题。为了便于调试，我简化了您的代码并添加了一些打印来跟踪正在发生的情况。我还添加了一个守卫on_message阻止机器人对其自身做出响应。
