TypeError:TextIOWrapper 类型的对象不是 JSON 可序列化的

2022-01-15 00:00:00 python json python-3.7 discord discord.py

问题描述

如果代码能够正常工作，那么每当有人在聊天中键入内容时，他们就会获得 5 经验，并且该信息会被放入 .json 文件中，但当有人在聊天中键入内容时会发生这种情况聊天它给了我这个错误.

If the code was to work properly then whenever someone types something in the chat they get 5 experience and that information gets put into a .json file, but instead what happens is whenever someone types something into the chat it gives me this error.

on_message users = json.dumps(f) 
TypeError: Object of type TextIOWrapper is not JSON serializable

这是我正在使用的代码:

Here is the code that I am using:

import discord
from discord.ext import commands
from discord.ext.commands import Bot
import asyncio
import json
from json import dumps, loads, JSONEncoder, JSONDecoder
import os

client = commands.Bot(command_prefix='^')
os.chdir(r'C:UsersquinyDesktopsauce')

@client.event
async def on_ready():
    print ("Ready when you are xd")
    print ("I am running on " + client.user.name)
    print ("With the ID: " + client.user.id)

@client.event
async def on_member_join(member):
    with open('users.json', 'r') as f: 
        users = json.dumps(f)

    await update_data(users, member)

    with open('users.json', 'w') as f:
        json.loads("users, f")

@client.event
async def on_message(message):
    with open('users.json', 'r') as f:
        users = json.dumps(f)

    await update_data(users, message.author)
    await add_experience(users, message.author, 5)
    await level_up(users, message.author, message.channel)

    with open('users.json', 'w') as f:
        json.loads("users, f")

async def update_data(users, user):
    if not user.id in users:
        users[user.id] = {}
        users[user.id]['experience'] = 0
        users[user.id]['level'] = 1

async def add_experience(users, user, exp):
    users[user.id]['experience'] += exp

async def level_up(users, user, channel):
    experience = users[user.id]['experience']
    lvl_start = users[user.id]['level']
    lvl_end = int(experience ** (1/4))

    if lvl_start < lvl_end:
        await client.send_message(channel, '{} has achieved a slightly higher 
level of {}, yay'.format(user.mention, lvl_end))
        users[user.id]['level'] = lvl_end

解决方案

你有你的 加载和dumps 向后，你应该使用 加载和转储 代替(s 后缀表示这些函数适用于字符串.).load 从文件 dump 到文件

You have your loads and dumps backwards, and you should be using load and dump instead (the s suffix means those functions work on strings.). load from a file, dump to a file

users = {}

@client.event
async def on_message(message):
    # No need to load the dictionary, our copy is the most correct
    await update_data(users, message.author)
    await add_experience(users, message.author, 5)
    await level_up(users, message.author, message.channel)
    with open('users.json', 'w') as f:
        json.dump(users, f)

@client.event
async def on_ready():
    print ("Ready when you are xd")
    print ("I am running on " + client.user.name)
    print ("With the ID: " + client.user.id)
    # Load the json just once, when the bot starts
    global users
    with open('users.json') as f:
        try:
            users = json.load(f)
        except:
            users = {}
