# # uvicorn main:app --host 0.0.0.0 --port 8001 --reload
uvicorn main:app --host 0.0.0.0 --port 8001 --reload 是什么意思？有什么作用？
这条命令是用来启动 FastAPI 应用程序的，具体使用了 Uvicorn 作为 ASGI 服务器。命令的各部分含义如下：
- uvicorn main:app: 这部分指定了 Uvicorn 服务器要运行的 ASGI 应用。main 是 Python 文件名（不包括 .py 扩展名），app 是在该文件中定义的 FastAPI 应用实例的变量名。
- --host 0.0.0.0: 这个选项指定服务器监听的主机地址。0.0.0.0 表示接受所有公网和私网的 IP 地址访问，使得服务器可以从任何 IP 地址接收请求。
- --port 8001: 指定服务器监听的端口号为 8001。客户端需要通过这个端口与服务器通信。
- --reload: 这个选项使得服务器在代码发生变化时自动重启，非常适合开发过程中使用，因为它可以即时反映代码的修改而无需手动重启服务器。
总的来说，这条命令的作用是在本地或服务器上启动一个 FastAPI 应用，监听所有 IP 地址的 8001 端口，并且开启自动重载功能，以便于开发过程中的调试和测试。
整个代码功能分析：
这份代码是一个使用 FastAPI 框架构建的 Web 应用程序，主要功能和关键点如下：
1. 数据库配置：
使用 SQLAlchemy 创建数据库引擎。
配置数据库连接，包括连接池大小、超时时间等。
2. 中间件配置：
添加了数据库会话中间件 DBSessionMiddleware。
配置了跨源资源共享（CORS）中间件，允许所有来源的请求。
3. 路由和控制器：
应用程序包含多个路由器，每个路由器管理不同的功能模块，如用户、工具、组织、项目等。
例如，user_router 处理与用户相关的请求，tool_router 处理与工具相关的请求。
4. 身份验证和授权：
使用 AuthJWT 处理 JWT 相关的操作，如创建访问令牌、加载配置等。
提供了登录接口，验证用户的邮箱和密码，成功后返回 JWT 访问令牌。
5. GitHub OAuth：
提供了 GitHub 登录和认证的接口，处理 OAuth 流程。
6. API 键验证：
提供了接口来验证不同的 API 键，如 LLM API 键和 OpenAI 键。
7. 启动事件：
在应用启动时执行一系列初始化任务，如注册工具包、替换旧的工作流等。
异常处理：
配置了针对 AuthJWTException 的异常处理器，用于处理 JWT 认证过程中的异常。
9. 其他 API：
提供了其他一些实用的 API，如获取当前登录用户、验证访问令牌的有效性等。
这份代码展示了一个复杂的 FastAPI 应用的典型结构，包括数据库操作、路由管理、身份验证和第三方服务集成等多个方面。

代码中定义了一个名为 tool_router 的 FastAPI 路由器，用于管理工具（Tool）的添加、查询、更新和删除。以下是每个路由的关键实现和要点：
1. 添加工具 (/add):
- 方法: POST
- 功能: 创建一个新的工具。
- 输入: 接收一个 ToolIn 类型的对象，包含工具的名称、文件夹名、类名和文件名。
- 处理: 创建一个 Tool 实例并将其添加到数据库中。
- 返回: 返回创建的工具的详细信息，使用 ToolOut 模型序列化。
- 异常: 如果创建过程中出现问题，会抛出 HTTP 400 错误。
2. 查询工具 (/get/{tool_id}):
- 方法: GET
- 功能: 根据工具 ID 获取工具的详细信息。
- 输入: 工具的 ID。
- 处理: 查询数据库中的对应工具。
- 返回: 返回工具的详细信息，使用 ToolOut 模型序列化。
- 异常: 如果工具不存在，会抛出 HTTP 404 错误。
3. 更新工具 (/update/{tool_id}):
- 方法: PUT
- 功能: 更新指定 ID 的工具。
- 输入: 工具的 ID 和新的工具信息（ToolIn 类型）。
- 处理: 查找并更新工具的信息。
- 返回: 返回更新后的工具信息，使用 ToolOut 模型序列化。
- 异常: 如果工具不存在，会抛出 HTTP 404 错误。
4. 删除工具:
- 代码中没有直接提供删除工具的路由，但通常这会通过一个 DELETE 请求实现，类似于更新和查询，只不过是从数据库中移除记录。
这些路由和控制器共同提供了完整的 CRUD 功能，使得用户可以通过 API 管理工具的整个生命周期。

继续分析下Tool类的实现。
Tool 类是一个 SQLAlchemy 模型，用于表示数据库中的 tools 表。以下是该类的关键实现原理和要点：
1. 属性定义:
- 类中定义了多个属性，每个属性都映射到数据库表的一个列。
- 使用 Column 类定义列的类型（如 Integer, String）和特性（如 primary_key, autoincrement）。
2. 表名定义:
- __tablename__ 属性用于指定这个模型映射到数据库中的表名。
3. 字符串表示 (__repr__ 方法):
- 重写 __repr__ 方法以提供类的实例的友好字符串表示，便于调试和日志记录。
4. 字典转换 (to_dict 方法):
- 提供 to_dict 方法将模型实例转换为字典，这在处理 HTTP 响应时非常有用。
5. 添加或更新工具 (add_or_update 静态方法):
- 这个方法首先尝试查询数据库中是否存在具有相同名称和 toolkit_id 的工具。
- 如果存在，则更新该工具的信息；如果不存在，则创建一个新的工具记录并添加到数据库。
6. 删除工具 (delete_tool 静态方法):
- 提供一个方法来删除指定名称的工具。
这些实现细节展示了 Tool 类如何与数据库交互，包括如何创建、更新、查询和删除记录。这是构建 RESTful API 的基础，允许通过 HTTP 请求管理
数据库记录。
另外工具集合形成ToolKit，如下：

Toolkit 类在应用程序中扮演着管理工具包（toolkits）的核心角色。具体来说，它的作用包括：
1. 数据模型定义：
- Toolkit 类定义了工具包的数据结构，包括工具包的名称、描述、是否显示、所属组织的 ID 和工具代码链接等属性。这些属性映射到数据库中的 toolkits 表的列。
2. 数据库交互：
- 该类通过 SQLAlchemy 提供的 ORM 功能，实现了对数据库中工具包数据的增删改查操作。例如，可以创建新的工具包、更新现有工具包的信息、查询工具包详情或列表，以及删除工具包。
3. 业务逻辑封装：
- 类中的方法如 add_or_update 封装了业务逻辑，例如检查同一组织下是否已存在同名的工具包，如果存在则更新，不存在则创建新的工具包。这样的封装使得业务逻辑集中管理，便于维护和修改。
4. 数据格式转换：
- 提供了 to_dict 和 to_json 方法，允许将工具包对象转换为字典或 JSON 格式，这对于生成 HTTP 响应非常有用。同时，from_json 方法允许从 JSON 格式数据创建工具包对象，便于处理来自前端的数据。
5. 接口支持：
- 通过定义如 fetch_marketplace_list 和 fetch_marketplace_detail 等类方法，Toolkit 类还支持与外部系统（如市场平台）的接口交互，获取市场上的工具包列表或详细信息。
总之，Toolkit 类是应用程序中管理工具包的关键组件，它不仅负责数据的持久化和检索，还处理与工具包相关的业务逻辑，提供数据的格式化输出，以及支持与外部系统的交互。这使得 Toolkit 成为构建和维护工具包功能的基础。
其中，marketplace的工具：
toolkit里有多个工具集，如下：
根据toolkit的功能，可以使用他的模板来创建一个agent：

这段代码中定义了几个与代理（Agent）调度相关的路由处理函数，涵盖了创建、停止、编辑和获取代理调度数据的功能。以下是每个函数的详细功能分析：
1. 创建并调度代理 1：
- 功能：创建一个新的代理并为其设置调度。
- 参数：
- agent_config_schedule: 包含代理配置和调度信息的对象。
- Authorize: 用于JWT认证。
- 处理流程：
- 验证项目存在性。
- 验证工具的有效性。
- 合并工具包中的工具。
- 创建代理配置。
- 创建新的代理调度。
- 提交数据库事务。
- 返回代理ID、名称、内容类型和调度ID。
- 异常处理：
- 如果项目不存在或工具无效，抛出404错误。
- 如果调度失败，抛出500错误。
2. 停止代理调度 2：
- 功能：停止给定代理的调度。
- 参数：
- agent_id: 代理的标识符。
- Authorize: 用于JWT认证。
- 处理流程：
- 查询并验证指定代理的调度状态。
- 更改调度状态为“STOPPED”。
- 提交数据库事务。
- 异常处理：

3. 编辑代理调度 3：
- 功能：编辑给定代理的调度信息。
- 参数：

4. 获取代理调度数据 4：
- 功能：获取指定代理的调度数据。
- 参数：
- agent_id: 代理的标识符。
- Authorize: 用于JWT认证。
- 处理流程：

- 根据用户时区调整时间显示。
- 返回当前日期时间、开始日期时间、重复间隔、到期日期和到期运行次数。
- 异常处理：
- 如果调度未找到，抛出404错误。
这些函数共同支持代理的生命周期管理，包括创建、调度、停止和编辑调度，以及获取调度相关数据，确保代理的操作按预定计划执行。每个函数都具备适当的异常处理机制，确保在出现问题时能够提供清晰的错误信息。
比如我的项目里有2个agent：

好了，我们最后看下super AGI最核心的ReAct实现。代码目录：

agent_prompt_builder.py output_handler.py tool_builder.py
AI代理的实现，主要涉及到任务队列、工具构建、消息构建、输出处理等多个方面。以下是核心实现算法和流程的分析：
核心类和方法
1. AgentIterationStepHandler:
- execute_step: 执行迭代工作流步骤。首先获取代理配置和执行实例，然后根据当前步骤的状态决定是否继续执行。如果有必要，它会构建工具，生成提示，发送消息，并处理响应。
2. AgentLlmMessageBuilder:
- build_agent_messages: 构建用于LLM（大型语言模型）的代理消息。这包括处理历史信息，生成提示，并可能包括完成提示。
3. AgentPromptBuilder:
- replace_main_variables 和 replace_task_based_variables: 这些方法用于构建和修改提示，将动态内容（如任务、工具、目标等）插入到提示模板中。
4. ToolOutputHandler:
- handle: 处理来自工具的输出。这可能涉及解析输出、应用业务逻辑，并最终生成适合用户的响应。
流程
1. 初始化:
- 代理通过 AgentIterationStepHandler 初始化，设置会话、模型、代理ID等。
2. 执行步骤:
- execute_step 方法是核心，它根据当前的执行状态和配置决定如何进一步处理。这可能包括等待权限、处理输入和输出、以及与LLM交互。
3. 消息构建:
- 使用 AgentLlmMessageBuilder 来构建发送给LLM的消息。这涉及到处理历史数据、构建提示和管理令牌限制。
4. 提示构建:
- AgentPromptBuilder 用于动态构建和调整提示，根据当前的任务和代理配置插入必要的变量。
5. 工具处理:
- ToolOutputHandler 处理工具的输出，将其转换为用户可以理解的格式，并处理任何必要的后续步骤。
6. 错误处理和日志:
- 在整个执行过程中，错误处理和日志记录是必不可少的，以确保问题可以被追踪并且代理行为符合预期。
因为本质上是ReAct思路，说下细节，目标任务分解、调度和执行主要通过以下几个关键组件实现：
1. 工作流和任务队列管理
AgentWorkflowStep 和 TaskQueue
- AgentWorkflowStep 类定义了工作流中的各个步骤。每个步骤可以是一个工具的执行、一个等待事件、或者是一个任务队列处理步骤。
- TaskQueue 类管理任务队列，支持添加任务、获取任务、完成任务等功能。它使用Redis作为后端存储，以支持任务的持久化和状态管理。
2. 工具执行和输出处理
ToolExecutor 和 ToolOutputHandler
- ToolExecutor 类负责执行具体的工具。它通过动态加载工具模块，并调用工具的执行方法，传入必要的参数。
- ToolOutputHandler 类处理工具执行后的输出。它可能会根据输出进行解析、执行后续的业务逻辑处理，或者生成适合用户的响应。
3. 工作流执行
AgentWaitStepHandler 和 QueueStepHandler
- AgentWaitStepHandler 类处理等待步骤。它会检查是否满足继续执行的条件，如等待时间的完成或外部事件的触发。
- QueueStepHandler 类处理队列步骤。它会从任务队列中获取任务，执行任务，并根据任务的结果决定下一步的操作。
4. 工作流调度
- 工作流的调度是通过在每个步骤执行完毕后，根据当前步骤的输出或状态决定下一步执行哪个步骤来实现的。
- 每个步骤可以配置下一步的跳转逻辑，支持基于条件的跳转。例如，一个步骤可以根据执行结果是成功还是失败，决定跳转到不同的步骤。
5. 示例：任务队列处理
class QueueStepHandler: def execute_step(self): execution = AgentExecution.get_agent_execution_from_id(self.session, self.agent_execution_id) workflow_step = AgentWorkflowStep.find_by_id(self.session, execution.current_agent_step_id) step_tool = AgentWorkflowStepTool.find_by_id(self.session, workflow_step.action_reference_id) task_queue = self._build_task_queue(step_tool) if not task_queue.get_status() or task_queue.get_status() == QueueStatus.COMPLETE.value: task_queue.set_status(QueueStatus.INITIATED.value) if task_queue.get_status() == QueueStatus.INITIATED.value: self._add_to_queue(task_queue, step_tool) execution.current_feed_group_id = "DEFAULT" task_queue.set_status(QueueStatus.PROCESSING.value) if not task_queue.get_tasks(): task_queue.set_status(QueueStatus.COMPLETE.value) return "COMPLETE" self._consume_from_queue(task_queue) return "default"在这个例子中，QueueStepHandler 类负责处理队列步骤。它首先检查任务队列的状态，然后根据状态添加任务到队列或从队列中消费任务。这个过程涉及到任务的获取、执行和状态更新。
总结
整个代码实现了一个复杂的AI代理工作流系统，通过类和方法的组合使用，实现了任务的分解、调度和执行。这些实现支持动态的工作流配置，能够根据不同的业务需求调整执行逻辑。
