TypeError：TextIOWrapper类型的对象不可JSON序列化

Question

如果代码正常运行，那么只要有人在聊天中输入内容，他们就会获得5点经验，并将这些信息放入.json文件中，但是，只要有人在聊天中输入内容，就会发生这种情况我这个错误。

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：

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:\Users\quiny\Desktop\sauce')

@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

您将loads和dumps倒退了，应该改用load和dump（s后缀表示这些函数在字符串上起作用）。 load从文件dump到文件

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 = {}

我遇到了这个错误，我错误地使用了 json.dump：

正确方法：

with open("Jello.json", "w") as json_file:
    json.dump(object_to_be_saved, json_file)

错误的方式：

我在 json.dump(json_file, object_to_be_saved) 周围做了相反的事情...谢谢 Python。
