# Harness Chat 接口文档
`POST /harness/chat`
## 1. 接口说明
- 路径：`/harness/chat`
- 方法：`POST`
- 内容类型：`application/json`
- 返回类型：`Flux<AgentEvent>`（**流式响应**，支持 SSE 与 JSON 数组两种方式）
- 功能：向智能体发送一条用户输入，返回一段**细粒度智能体事件流**。调用方按事件类型逐条解析即可渲染「思考中 / 正在调用工具 / 流式输出答案 / 需要人工确认」等 UI 状态。
> 源码位置：`mis-common/mis-common-harness/java/com/lcfc/harness/chat/HarnessChatGateway.java#L18-L23`
>
> ```java
> @PostMapping("/chat")
> public Flux<AgentEvent> chat(@RequestBody AgentChatRequest request) {
> ChatUiChannel channel = HarnessAgent.builder().build().channel(ChatUiChannel.create());
> SendOptions sendOptions = SendOptions.of(request.getUserId(), request.getSessionId());
> return channel.sendStream(sendOptions, request.getInput());
> }
> ```
## 2. 请求
### 2.1 请求头
| Header | 值 | 说明 |
| --- | --- | --- |
| `Content-Type` | `application/json` | 必填 |
| `Accept` | `text/event-stream` 或 `application/json` | 决定响应格式（见 §3） |
### 2.2 请求体（`AgentChatRequest`）
| 字段 | 类型 | 必填 | 说明 |
| --- | --- | --- | --- |
| `sessionId` | String | ✅ | 会话 ID；同一用户不同会话相互隔离 |
| `userId` | String | ✅ | 用户 ID；用于智能体命名空间隔离 / 会话路由 |
| `input` | String | ✅ | 用户输入内容 |
| `chatModel` | Object | ❌ | 聊天模型配置（`name`、`stream`、`temperature`） |
`chatModel` 结构：
| 字段 | 类型 | 默认值 | 说明 |
| --- | --- | --- | --- |
| `name` | String | - | 模型名称，如 `gpt-oss-120b` |
| `stream` | Boolean | `true` | 是否流式 |
| `temperature` | Double | `0.2` | 温度 |
### 2.3 请求示例
```json
POST /harness/chat
Host: localhost:8080
Content-Type: application/json
Accept: text/event-stream
{
"sessionId": "sess-20260918-001",
"userId": "user-10001",
"input": "帮我梳理今天的任务清单，生成一份 markdown 并保存到工作区",
"chatModel": {
"name": "gpt-oss-120b",
"stream": true,
"temperature": 0.2
}
}
```
> ⚠️ 注意：当前实现中 `chatModel` 并未被使用（`HarnessAgent.builder().build()` 未传入模型配置）。如需按请求指定模型，需要扩展 `HarnessChatGateway`。
## 3. 响应
### 3.1 格式一：SSE（推荐，`Accept: text/event-stream`）
每发生一个事件，服务端推送一条 `data:`，事件之间以空行分隔：
```
data:{"type":"AGENT_START","id":"4f9c1e2d8a7b4c5d9e0f1a2b3c4d5e6f","createdAt":"2026-09-18T02:30:45.123456Z","sessionId":"sess-20260918-001","replyId":"reply-7f3a91","name":"assistant","role":"assistant"}
data:{"type":"THINKING_BLOCK_START","id":"...","createdAt":"...","replyId":"reply-7f3a91","blockId":"blk-001"}
data:{"type":"TEXT_BLOCK_DELTA","id":"...","createdAt":"...","replyId":"reply-7f3a91","blockId":"blk-002","delta":"已完成"}
```
### 3.2 格式二：JSON 数组（默认 / `Accept: application/json`）
整个事件流序列化为一个 JSON 数组，随事件产生逐个写出：
```json
[
{ "type": "AGENT_START", "...": "..." },
{ "type": "THINKING_BLOCK_START", "...": "..." },
{ "type": "TEXT_BLOCK_DELTA", "...": "..." }
]
```
### 3.3 HTTP 状态
| 状态码 | 说明 |
| --- | --- |
| `200` | 正常，返回事件流 |
| `400` | 校验失败（`sessionId` / `userId` / `input` 为空时抛 `400 Bad Request`） |
| `500` | 智能体执行异常（模型未配置、会话中断等） |
## 4. 事件通用结构
所有事件（`AgentEvent`）都包含以下通用字段，通过 `type` 字段区分具体事件类型：
| 字段 | 类型 | 说明 |
| --- | --- | --- |
| `type` | String | **类型判别器**，取值见 §5 |
| `id` | String | 事件唯一 ID（32 位十六进制，无连字符 UUID） |
| `createdAt` | String | 事件创建时间，ISO-8601 格式（如 `2026-09-18T02:30:45.123456Z`） |
| `source` | String | 事件来源路径。顶层智能体事件为 `null`；子智能体转发的事件为 `main/researcher` 形式。**无值时缺省（不输出）** |
| `metadata` | Object | 附加元数据，**空时不输出** |
仅 `type` / `id` / `createdAt` 必现；其余字段视事件类型而定。以下各事件示例均基于同一会话回环 `"replyId":"reply-7f3a91"`。

## 6. 典型一轮完整事件流（SSE，按顺序）
以「用户要求整理任务清单并保存为 markdown」为例（含工具调用）：
```text
data:{"type":"AGENT_START","id":"...","createdAt":"...","sessionId":"sess-20260918-001","replyId":"reply-7f3a91","name":"assistant","role":"assistant"}
data:{"type":"MODEL_CALL_START","id":"...","createdAt":"...","replyId":"reply-7f3a91"}

data:{"type":"THINKING_BLOCK_DELTA","id":"...","createdAt":"...","replyId":"reply-7f3a91","blockId":"blk-001","delta":"先读取任务源文件，再生成 markdown"}
data:{"type":"THINKING_BLOCK_END","id":"...","createdAt":"...","replyId":"reply-7f3a91","blockId":"blk-001"}
data:{"type":"MODEL_CALL_END","id":"...","createdAt":"...","replyId":"reply-7f3a91","usage":{"inputTokens":520,"outputTokens":80,"cachedTokens":0,"time":0.41,"totalTokens":600}}
data:{"type":"TOOL_CALL_START","id":"...","createdAt":"...","replyId":"reply-7f3a91","toolCallId":"call_9f2c4d","toolCallName":"shell_execute"}
data:{"type":"TOOL_CALL_DELTA","id":"...","createdAt":"...","replyId":"reply-7f3a91","toolCallId":"call_9f2c4d","toolCallName":"shell_execute","delta":"{\"command\":\"cat /tasks.json\"}"}

data:{"type":"TEXT_BLOCK_START","id":"...","createdAt":"...","replyId":"reply-7f3a91","blockId":"blk-002"}
data:{"type":"TEXT_BLOCK_DELTA","id":"...","createdAt":"...","replyId":"reply-7f3a91","blockId":"blk-002","delta":"已完成，"}
data:{"type":"TEXT_BLOCK_DELTA","id":"...","createdAt":"...","replyId":"reply-7f3a91","blockId":"blk-002","delta":"任务清单已保存至 /workspace/tasks.md"}
data:{"type":"TEXT_BLOCK_END","id":"...","createdAt":"...","replyId":"reply-7f3a91","blockId":"blk-002"}
data:{"type":"AGENT_RESULT","id":"...","createdAt":"...","result":{"id":"550e8400-e29b-41d4-a716-446655440000","name":"assistant","role":"ASSISTANT","content":[{"type":"text","text":"已完成，任务清单已保存至 /workspace/tasks.md"}],"metadata":{"agentscope_generate_reason":"MODEL_STOP"},"timestamp":"2026-09-18 10:30:48.200","usage":{"inputTokens":1600,"outputTokens":330,"cachedTokens":512,"time":1.8,"totalTokens":1930}}}
data:{"type":"AGENT_END","id":"...","createdAt":"...","replyId":"reply-7f3a91"}
```
事件一般顺序：`AGENT_START` → （`MODEL_CALL_*` / `THINKING_BLOCK_*` / `TOOL_CALL_*` / `TOOL_RESULT_*` 可能多轮循环） → `TEXT_BLOCK_*` → `AGENT_RESULT` → `AGENT_END`。涉及 HITL 时会插入 `REQUIRE_USER_CONFIRM`（见 §5.23）。
## 7. 注意事项
1. **延续会话**：同一 `(userId, sessionId)` 组合的上下文会自动累积；不同会话互不干扰。`REQUEST_STOP` 或 `REQUIRE_USER_CONFIRM` 暂停后，用相同 `sessionId` 再发一次请求即可恢复执行。
2. **事件 ID**：`id` 为 32 位十六进制（无连字符 UUID），可用于调试与去重；`createdAt` 为 ISO-8601（UTC）。
3. **未知事件**：前端对 `type: CUSTOM` 中未知的 `name` 应静默跳过；对表外未知 `type` 应尽量容忍（服务端可能升级新增事件）。
4. **空字段省略**：顶层事件的 `source`、`metadata` 及无值字段在 JSON 中缺省（`NON_NULL` 策略）；`Msg` 内部字段（如 `name`、`usage`）则为 `null` 或对象。

## 查询智能体用户数
## 查智能体用户数
```sql
select '单智能体' AS agent_type, agent.agent_id, agent.agent_name, IFNULL(aus.user_num,0) AS user_num from `agent` AS agent left join agent_usage_stats AS aus ON agent.agent_id = aus.agent_id where agent.del_flag = '0'
select
'单智能体' AS agent_type,
agent.agent_id,
agent.agent_name,
IFNULL (aus.user_num, 0) AS user_num
from
`agent` AS agent
left join agent_usage_stats AS aus ON agent.agent_id = aus.agent_id
where
agent.del_flag = '0'
UNION ALL
select '多智能体' AS agent_type, ma.agent_id, ma.agent_name, IFNULL(maus.user_num,0) AS user_num from `multi_agent_main` AS ma left join agent_usage_stats AS maus ON ma.agent_id = maus.agent_id where ma.del_flag = '0';
select
'多智能体' AS agent_type,
ma.agent_id,
ma.agent_name,
IFNULL (maus.user_num, 0) AS user_num
from
`multi_agent_main` AS ma
left join agent_usage_stats AS maus ON ma.agent_id = maus.agent_id
where
ma.del_flag = '0';
```
## 查客户端是否登录
```sql
select
*
from
`mis-cloud-claw`.`sys_logininfor`
where
client_key = (
select
client_key
from
`mis-cloud-claw`.`sys_client`
where
`client_id` = '客户端ID'
);
```
## 查智能体对话日志
1. 查询所有切片号，假设查询出来的`part`是[1,2]
```sql
select part from log_agent_chat where del_flag = '0';
```
2. 根据切片号查询并合并各个切片表的数据
```sql
select * from log_agent_chat_1 where chat_window_id = 会话ID
UNION ALL
select * from log_agent_chat_2 where chat_window_id = 会话ID
```
## 查智能体信息
必须提供**智能体ID**，在不明确用户查询的是单智能体还是多智能体时，友好的询问要查询哪种智能体。
1. 查询单智能体信息
```sql
with agent_info AS (
select
agent_id,
agent_name,
system_prompt,
`description`,
max_messages,
max_tokens,
kb_uuids,
kb_configs,
kb_similarity_threshold,
kb_top_k,
kb_max_recall_toekn,
llm_name,
long_term_memory,
case kb_mode when '1' then '直接检索' when '2' then 'tool检索' else '' end AS kb_mode,
case kb_search_type when '0' then '向量检索' when '1' then '混合检索' when '2' then '智能检索' else '' end AS kb_search_type
from mis-agent.agent
where agent_id = <智能体ID>
),
agent_skill AS (
select
<智能体ID> AS agent_id,
GROUP_CONCAT(skill_name) AS skill_names
from mis-mcp.skill
where skill_id in (
select skill_id from mis-agent.agent_skill_mapping
where agent_id = <智能体ID>
)
),
agent_mcp_tool AS (
select
<智能体ID> AS agent_id,
GROUP_CONCAT(tool_name) AS tool_names
from mis-mcp.map_tools
where mcp_server_uuid in (
select mcp_server_uuid from mis-agent.agent_tool_mapping
where relate_agent_id = <智能体ID>
)
)
select * from agent_info AS a
left join agent_skill AS b on a.agent_id = b.agent_id
left join agent_mcp_tool AS c on a.agent_id = c.agent_id
```
2. 查询多智能体信息
```sql
select * from mis-agent.agent_release_info where release_id in (
select
release_id
from mis-agent.multi_agent_sub
where main_agent_id = <智能体ID>
)
```
## 查智能体使用数据
必须提供**智能体ID**。
```sql
select * from mis-agent.agent_usage_stats_daily where agent_id = <智能体ID> order by daily desc
```
## 查项目统计数据
必须提供**项目名称**。
1. 查询项目注册表，判断是否包含该项目。用户提供的项目名称大概率是模糊的，比如"认证"、"ebiz"，要根据语义判断究竟是哪一个，如果猜不准就询问一下用户是哪个。
```sql
select * from mis-agent.project_stats_registry
```
**重要：`project_stats_registry`里的`id`字段，称为项目ID，或者叫project_id，后面的步骤需要用到。**
2. 查询项目统计数据
```sql
select * from mis-agent.project_data_stats_daily where project_id = <project_id>
```
## 新增devco账号
用户的输入格式如下。
```text
devco
username1
username2
username3
```
- 在用户的输入中，`devco`是触发d当前技能的关键词。
- **从第二行开始，去掉空白行以后，每一个都是用户名。**如果用户提供的用户名存在重复，请忽略大小写保留1个即可。
- `client_id`和`state`字段是固定值，用户名对应的是`account`字段。
**在`mis-dev`资源下的`mis-cloud-paw`库中执行**批量插入sql，示例：
```sql
INSERT INTO external_login_client_account (client_id, account, state) VALUES
('226c18408b5705449f37b621a432a6d3', 'username1', 1),
('226c18408b5705449f37b621a432a6d3', 'username2', 1),
('226c18408b5705449f37b621a432a6d3', 'username3', 1);
```
## 查paw-agent信息
在`mis-dev`资源下，根据用户名（username）查询paw-agent信息，如果用户没有提供username，友好的提问要查哪个用户的，一个可用的username示例：`Agnes2.wang`。
1. 根据用户提供的`username`查询`user_id`，只会查出来1行数据，示例：
```sql
select user_id from `mis-cloud-claw`.`sys_user` where user_name = '{username}';
```
2. 根据`user_id`查询agent信息，可能返回多行数据，使用markdown表格的形式展示每一行的数据，示例：
```sql
select
agent_id,
agent_mode,
publish_status,
publish_scope,
published_at,
version_lane,
key_scope_default
from
`mis-paw-claw`.`agent`
where
create_by = < user_id >;
```
