問題描述

我正在嘗試為在大約有 50-60 人輸入的房間中輸入的消息打分.它將第一次將用戶添加到 JSON 文件中，但不會為他們鍵入的消息添加任何分數.我再次對其進行了測試，只有一個用戶獲得了他們輸入的消息的積分，其余的保持不變.代碼如下:

I'm trying to give points for messages typed in a room that has around 50-60 people that type in it. It will add the user to the JSON file the first time, but it won't add any more points for the messages they type. I tested it again and only one user was getting points for the messages they typed and the rest remained the same. Here is the code:

 @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

推薦答案

我們應該只需要讀取一次文件，然后在需要時將修改保存到文件中.我沒有注意到任何會導致所描述行為的邏輯錯誤，因此這可能是關于允許您的機器人查看哪些消息的權限問題.為了便于調試，我簡化了您的代碼并添加了一些打印來跟蹤正在發生的事情.我還在 on_message 中添加了一個守衛，以阻止機器人對其自身做出響應.

We should only need to read the file once, and then just save our modifications to the file when we need to. I didn't notice any logical errors that would lead to the behavior described, so it may be a permissions issue regarding what messages your bot is allowed to see. To facilitate debugging, I've simplified your code and added some prints to track what's going on. I also added a guard in on_message to stop the bot from responding to itself.

import json
import discord

client = discord.Client()

try:
    with open("users.json") as fp:
        users = json.load(fp)
except Exception:
    users = {}

def save_users():
    with open("users.json", "w+") as fp:
        json.dump(users, fp, sort_keys=True, indent=4)

def add_points(user: discord.User, points: int):
    id = user.id
    if id not in users:
        users[id] = {}
    users[id]["points"] = users[id].get("points", 0) + points
    print("{} now has {} points".format(user.name, users[id]["points"]))
    save_users()

def get_points(user: discord.User):
    id = user.id
    if id in users:
        return users[id].get("points", 0)
    return 0

@client.event
async def on_message(message):
    if message.author == client.user:
        return
    print("{} sent a message".format(message.author.name))
    if message.content.lower().startswith("!points"):
        msg = "You have {} points!".format(get_points(message.author))
        await client.send_message(message.channel, msg)
    add_points(message.author, 1)

client.run("token")
