使用atproto包的Bluesky机器人突发故障求助

错误原因 #

11月7日Bluesky官方更新了认证接口的JWT返回格式，新增了aud（受众）字段，但你当前使用的旧版本atproto库的JwtPayload类并未定义该参数，导致登录解析JWT时抛出类型错误。

解决方案 #

方案1：升级atproto库到最新版本（推荐） #

执行以下命令更新依赖，新版本已适配Bluesky的JWT格式变更：

pip install --upgrade atproto

更新后重新运行机器人代码即可。

方案2：临时修改库源码（仅应急用） #

如果暂时无法升级，可找到本地/VPS上atproto库的auth.py文件（路径参考报错信息中的C:\Users\username\AppData\Local\Programs\Python\Python311\Lib\site-packages\atproto\xrpc_client\client\auth.py），修改JwtPayload类的定义，添加aud参数：

class JwtPayload(BaseModel):
    sub: str
    exp: int
    aud: Optional[str] = None  # 新增该行

保存后重新运行代码。
