Discord.py客户端登录失败：传入令牌无效问题求助

我用Discord.py编写了一个基于客户端令牌的简单机器人，但登录时遇到LoginFailure: Improper token has been passed.错误，尝试多种方法仍无法解决，请求技术帮助。

我的代码 #

import discord
from decimal import Decimal
import os
from dotenv import load_dotenv

client = discord.Client(intents=discord.Intents.default())

intents = discord.Intents.default()
intents.messages = True
load_dotenv()
my_var = os.environ['TOKEN']
print(my_var)
print(type(m))
@client.event
async def on_ready():

    print('Bot Have Logged In as {0.user'.format(client))


# (webpackChunkdiscord_app.push([[''],{},e=>{m=[];for(let c in e.c)m.push(e.c[c])}]),m).find(m=>m?.exports?.default?.getToken!==void 0).exports.default.getToken()


client.run(os.getenv('TOKEN'))

运行时错误信息 #

解决方法 #

1. 核心问题：令牌类型不匹配 #

discord.Client()是为机器人账号设计的，必须使用Discord开发者平台生成的机器人令牌，而非用户客户端令牌：

• 用户客户端令牌是个人账号的认证凭证，Discord官方禁止用它登录机器人，违反服务条款，会导致账号封禁。
• 如果是开发机器人，需前往Discord开发者平台创建应用，添加机器人后复制其专属令牌。

2. 修复代码中的语法错误 #

• 代码中print(type(m))的m未定义，直接运行会报错，需删除该行或定义变量。
• on_ready中的格式化字符串少了闭合的}，原代码'{0.user'.format(client)应改为'{0.user}'.format(client)，或用更简洁的f-string：f'Bot已登录为 {client.user}'。

3. 修正Intents配置逻辑 #

你先初始化了client再定义intents，导致配置的intents未生效，正确顺序是先配置intents再初始化客户端：

intents = discord.Intents.default()
intents.messages = True
client = discord.Client(intents=intents)

4. 环境变量读取优化 #

• 用os.getenv('TOKEN')替代os.environ['TOKEN']，避免变量不存在时直接抛出KeyError。
• 增加令牌读取校验，确保能正确获取到值：

  token = os.getenv('TOKEN')
  if not token:
      raise ValueError("未从环境变量中读取到TOKEN，请检查.env文件配置")
  

修复后的完整代码 #

import discord
import os
from dotenv import load_dotenv

# 先配置Intents
intents = discord.Intents.default()
intents.messages = True
# 初始化客户端并传入配置好的intents
client = discord.Client(intents=intents)

# 加载环境变量
load_dotenv()
token = os.getenv('TOKEN')

# 校验令牌是否存在
if not token:
    raise ValueError("未从环境变量中读取到TOKEN，请检查.env文件")
# 打印令牌前10位确认（避免泄露完整令牌）
print(f"读取到的令牌：{token[:10]}...")

@client.event
async def on_ready():
    print(f'Bot已登录为 {client.user}')

client.run(token)
