TypeError：TextIOWrapper类型的对象不可JSON序列化

Question

如果代码能够正常工作，那么每当有人在聊天中键入某些内容时，他们都会获得5点经验，并将这些信息保存到.json文件中，但是，当有人在聊天中键入某些内容时，会发生此错误。

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

我遇到了这个错误，并且我使用了json.dump错误的方法：

正确方法：

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

错误的方法：

我用相反的方式做了json.dump(json_file, object_to_be_saved)......谢谢Python。

你有你loads和dumps倒退，你应该使用load和dump替代（该s后缀手段的功能处理字符串）。 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 = {}
