Discord自机器人登录失败：传入令牌无效问题求助

问题 #

运行Discord自机器人脚本时持续触发登录失败错误，错误栈如下：

Traceback (most recent call last):
  File "C:\Users\AppData\Local\Programs\Python\Python310\lib\site-packages\discord\http.py", line 803, in static_login

    raise HTTPException(response, data)
discord.errors.HTTPException: 401 Unauthorized (error code: 0): 401: Unauthorized
The above exception was the direct cause of the following exception:

已尝试更换多个账号令牌，均出现相同错误。

解决方案 #

1. 降级Discord.py版本 #

Discord官方已禁止自机器人，v2.0及以上版本的Discord.py完全移除了自机器人支持，即使传入正确令牌也会触发登录失败。

• 执行命令降级到兼容版本：pip install discord.py==1.7.3
• 注意：使用自机器人违反Discord服务条款，可能导致账号封禁，操作需自行承担风险。

2. 验证令牌有效性 #

• 确保使用的是用户令牌而非机器人令牌：机器人令牌无法用于自机器人登录，用户令牌需从Discord客户端开发者工具获取（该操作同样违反Discord条款）。
• 检查令牌格式：用户令牌通常以Nz...或MTA...开头，复制时不要包含多余空格、换行或引号。

3. 确认账号状态 #

• 确保账号未被封禁、限制，且能正常通过网页端登录。
• 若账号开启了双重验证，需先在当前设备完成账号验证，避免登录时触发安全拦截。

4. 修正代码细节 #

• 将MY_CHANNEL_ID改为整数类型：当前代码中赋值为字符串，需替换为实际数字ID（如MY_CHANNEL_ID = 123456789012345678），否则后续发送消息时会因channel为None报错。
