ACP 服务器认证系统完整实现

概述

本 PR 为 Kimi Code CLI 的 ACP 服务器实现了一个完整、健壮的认证系统,支持终端登录和 OAuth Device Flow 两种认证方式。

主要变更

🔐 核心认证架构

组件 说明
_check_auth() 统一的认证状态检查,未认证时抛出 AUTH_REQUIRED
_trigger_login_in_terminal() 通过 ACP 终端协议执行登录命令
_trigger_oauth_device_flow() OAuth Device Flow 备选方案
_send_auth_progress() 通过 AgentMessageChunk 发送认证进度
authenticate() 统一的认证入口,自动选择最佳认证方式

🖥️ 终端登录流程

客户端调用 authenticate
    ↓
检查客户端终端支持
    ↓
create_terminal → 执行登录命令
    ↓
wait_for_terminal_exit
    ↓
load_tokens 验证 → 发送进度通知

关键特性:

  • PyInstaller frozen binary 兼容(自动检测 sys.frozen
  • 使用 shlex.quote 处理含空格路径
  • 区分 RequestError 和意外异常
  • 资源清理(finally 块释放终端)

📱 OAuth Device Flow 备选

当客户端不支持终端或无活跃 session 时自动回退:

if session_id != "__auth__" and client_capabilities.terminal:
    return await self._trigger_login_in_terminal(session_id)
else:
    return await self._trigger_oauth_device_flow(session_id)

关键特性:

  • 使用 login_kimi_code 异步生成器
  • 支持非 session 场景(__auth__ 哨兵值)
  • 实时进度:verification_url → waiting → success/error

🔄 认证进度通知

通过 ACP 协议发送状态更新:

状态 说明
verification_url 发送验证 URL 给客户端
waiting 等待用户完成认证
completed 认证成功
failed 认证失败
cancelled 用户取消认证

🛡️ 安全性改进

  • 认证检查位置优化resume_session 仅在加载新 session 时检查认证
  • 规范化错误格式_build_auth_methods_data() 确保 AUTH_REQUIRED 错误格式一致
  • 异常链清理CancelledError 转换为协议错误(from None 隐藏内部细节)

代码质量

重构亮点

  1. 消除重复代码:提取 _build_auth_methods_data() 方法(原代码重复 3 次)
  2. 统一配置保存set_session_model 使用 reload + 特定字段更新模式
  3. Session 状态同步:模型切换后更新 self.sessions[session_id]

文档更新

  • AGENTS.md:移除 authenticate 未实现标记,新增 Authentication 章节

测试覆盖

tests/acp/test_server_auth.py
├── TestTriggerLoginInTerminal (3 tests)
├── TestTriggerOAuthDeviceFlow (3 tests)
├── TestAuthenticate (4 tests)
├── TestCancelAuth (1 test)
├── TestSendAuthProgress (2 tests)
└── TestCheckAuth (1 test)

Total: 14 tests passed

破坏性变更

无。完全向后兼容。

修复问题

  1. IDE 集成失败:规范化 AUTH_REQUIRED 错误格式
    Failed to initialize ACP session. Error: Internal error: "list.index(x): x not in list" #1355
    Jetbrains IDE kimi不可用 #1334
  2. PyInstaller 打包:正确处理 frozen binary 场景
  3. Session 恢复安全漏洞resume_session 仅在加载新 session 时检查认证
  4. 模型切换状态不一致:更新 self.sessions 中的模型信息

…lize

Fixes an issue where IDE integration fails with 'list.index(x): x not in list'
when sys.argv doesn't contain 'kimi' (e.g., when started via python -m kimi_cli).

- Wrap sys.argv.index('kimi') in try/except ValueError
- Add test coverage for initialize method with various sys.argv scenarios

P2 Badge Remove tautological assertion from session-id auth test

assert "specific-session" in server_with_conn._active_auth_sessions or True is always true, so this test never verifies that authenticate(..., session_id="specific-session") actually binds auth state to the caller-provided session. If the implementation regresses to using the wrong session key, this case will still pass and the multi-session bug will go undetected in CI.
