+# 虚拟机系统工具：获取文件链接 (sandbox_get_file_url)
+
+## 一、需求概述
+
+为虚拟机（Agent Sandbox）新增一个系统级工具 `sandbox_get_file_url`：
+
+1. Agent 调用该工具，传入虚拟机内的文件路径
+2. 系统从虚拟机读取文件内容
+3. 将文件上传到 S3（使用对话的 Chat Bucket 实例）
+4. 返回 2 小时有效期的签名访问 URL
+
+**工具返回格式**：
+```json
+{
+  "url": "https://xxx.s3.amazonaws.com/...",
+  "expired": "2 hours",
+  "filename": "output.csv"
+}
+```
+
+---
+
+## 二、涉及文件
+
+| 文件 | 变更类型 | 说明 |
+|------|----------|------|
+| `packages/global/core/ai/sandbox/constants.ts` | 修改 | 新增工具定义、Schema、更新系统提示词 |
+| `packages/service/core/ai/sandbox/toolCall.ts` | 新增 | 沙盒工具统一执行层 `callSandboxTool()`，两条链路共享 |
+| `packages/service/core/workflow/dispatch/ai/tool/toolCall.ts` | 修改 | 统一拦截所有 sandbox 工具，复用 `callSandboxTool` |
+| `packages/service/core/workflow/dispatch/ai/agent/sub/sandbox/index.ts` | 修改 | 新增 `dispatchSandboxGetFileUrl()`，复用 `callSandboxTool` |
+| `packages/service/core/workflow/dispatch/ai/agent/master/call.ts` | 修改 | 新增工具拦截逻辑（Agent 模式） |
+| `packages/service/common/s3/buckets/base.ts` | 修改 | `uploadFileByBody` 新增 `filename`、`expiredTime` 参数 |
+| `packages/service/common/s3/sources/chat/index.ts` | 修改 | `uploadChatFile` 透传 `filename`、`expiredTime` |
+| `packages/service/common/s3/type.ts` | 修改 | `UploadFileByBodySchema` 新增 `filename`、`expiredTime` 字段 |
+| `packages/service/common/s3/sources/chat/type.ts` | 修改 | `UploadChatFileSchema` 新增 `expiredTime` 字段 |
+| `projects/app/src/pages/api/system/file/[jwt].ts` | 修改 | 下载接口支持 `Content-Disposition` 响应头 |
+
+> **架构说明**：新增 `callSandboxTool` 作为纯执行层，不绑定业务响应格式。两条调用链路（普通工作流 / Agent 模式）均复用该层，消除重复逻辑。
+
+> **URL 生成**：文件上传到 S3 后，通过 `jwtSignS3ObjectKey(key, expiredAt)` 生成 JWT 签名的内网访问 URL（有效期 2 小时），不依赖 S3 签名 URL。
+
+---
+
+## 三、详细设计
+
+### 3.1 工具定义（constants.ts）
+
+新增常量与 Schema：
+
+```typescript
+export const SANDBOX_READ_FILE_TOOL_NAME: I18nStringType = {
+  'zh-CN': '虚拟机/获取文件链接',
+  'zh-Hant': '虛擬機/獲取文件鏈接',
+  en: 'Sandbox/Get File URL'
+};
+export const SANDBOX_GET_FILE_URL_TOOL_NAME = 'sandbox_get_file_url';
+
+// 参数为 paths 数组，支持同时获取多个文件
+export const SandboxGetFileUrlToolSchema = z.object({
+  paths: z.array(z.string())
+});
+
+export const SANDBOX_GET_FILE_URL_TOOL: ChatCompletionTool = {
+  type: 'function',
+  function: {
+    name: SANDBOX_GET_FILE_URL_TOOL_NAME,
+    description: '从虚拟机读取指定文件，上传至云存储，返回 2 小时有效期的访问链接',
+    parameters: {
+      type: 'object',
+      properties: {
+        paths: {
+          type: 'array',
+          items: {
+            type: 'string',
+            description: '文件访问路径，例如: output.csv'
+          },
+          description: '文件访问路径，例如: ["output.csv", "output.txt"]'
+        }
+      },
+      required: ['paths']
+    }
+  }
+};
+
+// 更新 SANDBOX_TOOLS（追加新工具）
+export const SANDBOX_TOOLS: ChatCompletionTool[] = [SANDBOX_SHELL_TOOL, SANDBOX_GET_FILE_URL_TOOL];
+```
+
+更新系统提示词（`SANDBOX_SYSTEM_PROMPT`），追加工具说明：
+```
+- 若需要将生成的文件分享给用户，可使用 ${SANDBOX_GET_FILE_URL_TOOL_NAME} 工具获取文件的临时访问链接（有效期 2 小时）
+```
+
+---
+
+### 3.2 沙盒工具统一执行层（toolCall.ts）
+
+新增 `packages/service/core/ai/sandbox/toolCall.ts`，作为所有沙盒工具的纯执行层，不绑定业务响应格式：
+
+```typescript
+type SandboxToolCallParams = {
+  toolName: string;
+  rawArgs: string;
+  appId: string;
+  userId: string;
+  chatId: string;
+};
+
+export type SandboxToolCallResult = {
+  input: Record<string, any>;
+  response: string;
+  durationSeconds: number;
+};
+
+export const callSandboxTool = async (params: SandboxToolCallParams): Promise<SandboxToolCallResult>
+```
+
+**`sandbox_get_file_url` 执行逻辑**：
+1. 解析 `paths` 数组参数
+2. 用 `Promise.all` 并发处理每个文件路径：
+   - 通过 `instance.provider.readFileStream(filePath)` 流式读取文件内容
+   - 聚合 chunks 为 `Buffer`
+   - 调用 `chatBucket.uploadChatFile({ ..., expiredTime: addHours(now, 2) })` 上传，TTL 设为 2 小时
+   - 用 `jwtSignS3ObjectKey(key, addHours(now, 2))` 生成 JWT 签名访问 URL
+3. 返回 `Array<{ fileUrl: string, filename: string }>`
+
+**工具返回格式**（JSON 序列化后作为 response）：
+```json
+[
+  { "fileUrl": "https://app.xxx.com/api/system/file/eyJ...", "filename": "output.csv" },
+  { "fileUrl": "https://app.xxx.com/api/system/file/eyJ...", "filename": "report.txt" }
+]
+```
+
+> **注意**：URL 不再使用 S3 签名 URL（`accessUrl`），而是通过 `jwtSignS3ObjectKey` 生成 JWT 签名的内部访问 URL，由 `/api/system/file/[jwt]` 接口代理下载。
+
+---
+
+### 3.3 S3 上传（uploadFileByBody 扩展）
+
+扩展 `packages/service/common/s3/type.ts` 的 `UploadFileByBodySchema`，新增 `filename`（必填）和 `expiredTime`（可选）字段：
+
+```typescript
+export const UploadFileByBodySchema = z.object({
+  buffer: z.instanceof(Buffer),
+  contentType: z.string().optional(),
+  key: z.string().nonempty(),
+  filename: z.string().nonempty(),       // 新增，用于 Content-Disposition
+  expiredTime: z.date().optional()       // 新增，不传则默认 now + 1h
+});
+```
+
+`uploadFileByBody` 使用 `expiredTime` 写入 MongoS3TTL，并将 `filename` 写入对象 metadata：
+
+```typescript
+metadata: {
+  contentDisposition: `attachment; filename="${encodeURIComponent(filename)}"`,
+  originFilename: encodeURIComponent(filename),
+  uploadTime: new Date().toISOString()
+}
+```
+
+`uploadChatFile` 同步透传 `filename` 和 `expiredTime` 到底层方法。
+
+---
+
+### 3.4 封装方法（sub/sandbox/index.ts）
+
+`dispatchSandboxGetFileUrl` 直接复用 `callSandboxTool`，与 `dispatchSandboxShell` 模式一致：
+
+```typescript
+export const dispatchSandboxGetFileUrl = async ({
+  filePath,   // 保持参数名，内部转为 paths: [filePath]
+  appId,
+  userId,
+  chatId,
+  lang
+}: SandboxDispatchParams & { filePath: string }): Promise<SandboxDispatchResult> => {
+  const { input, response, durationSeconds } = await callSandboxTool({
+    toolName: SANDBOX_GET_FILE_URL_TOOL_NAME,
+    rawArgs: JSON.stringify({ paths: [filePath] }),
+    appId,
+    userId,
+    chatId
+  });
+
+  return {
+    response,
+    usages: [],
+    nodeResponse: buildNodeResponse({ toolId: SANDBOX_GET_FILE_URL_TOOL_NAME, input, response, durationSeconds, lang })
+  };
+};
+```
+
+---
+
+### 3.5 工具拦截逻辑（两条链路）
+
+两条链路均通过 `callSandboxTool` 统一处理，不再各自内联逻辑。
+
+#### 3.5.1 普通工作流：toolCall.ts
+
+`handleToolResponse` 中合并 `SANDBOX_TOOL_NAME` 和 `SANDBOX_GET_FILE_URL_TOOL_NAME` 到同一拦截块：
+
+```typescript
+if (
+  call.function?.name === SANDBOX_TOOL_NAME ||
+  call.function?.name === SANDBOX_GET_FILE_URL_TOOL_NAME
+) {
+  const { input, response, durationSeconds } = await callSandboxTool({
+    toolName: call.function.name,
+    rawArgs: call.function.arguments ?? '',
+    appId: String(workflowProps.runningAppInfo.id),
+    userId: String(workflowProps.uid),
+    chatId: workflowProps.chatId
+  });
+
+  const flowResponse = getSandboxToolWorkflowResponse({
+    name: tool.name,
+    logo: SANDBOX_ICON,
+    toolId: call.function.name,
+    input,
+    response,
+    durationSeconds
+  });
+
+  return { response, flowResponse };
+}
+```
+
+#### 3.5.2 Agent 模式：agent/master/call.ts
+
+紧跟 `SANDBOX_TOOL_NAME` 拦截块之后，添加对 `SANDBOX_GET_FILE_URL_TOOL_NAME` 的处理，复用 `dispatchSandboxGetFileUrl`：
+
+```typescript
+if (toolId === SANDBOX_GET_FILE_URL_TOOL_NAME) {
+  const toolParams = SandboxGetFileUrlToolSchema.safeParse(parseJsonArgs(call.function.arguments));
+  if (!toolParams.success) return { response: toolParams.error.message, usages: [] };
+
+  const result = await dispatchSandboxGetFileUrl({
+    filePath: toolParams.data.paths[0],  // Agent 模式单文件路径
+    appId: runningAppInfo.id,
+    userId: props.uid,
+    chatId,
+    lang: props.lang
+  });
+
+  childrenResponses.push(result.nodeResponse);
+  return { response: result.response, usages: result.usages };
+}
+```
+
+---
+
+## 四、执行流程
+
+### 4.1 普通工作流链路（toolCall.ts）
+
+```mermaid
+sequenceDiagram
+    participant Tool as ToolCall 节点
+    participant Handler as toolCall.ts 拦截
+    participant CallLayer as callSandboxTool()

+    participant S3 as S3ChatSource.uploadChatFile()
+    participant DB as MongoS3TTL
+
+    Tool->>Handler: 调用 sandbox_get_file_url({ paths })
+    Handler->>CallLayer: callSandboxTool({ toolName, rawArgs, ... })
+    loop 每个 path（并发）
+      CallLayer->>SandboxProvider: readFileStream(filePath)
+      SandboxProvider-->>CallLayer: AsyncIterable<Uint8Array>
+      CallLayer->>CallLayer: Buffer.concat(chunks)
+      CallLayer->>S3: uploadChatFile({ filename, buffer, expiredTime: +2h })
+      S3->>DB: MongoS3TTL.create(expiredTime = now + 2h)
+      S3-->>CallLayer: { key }
+      CallLayer->>CallLayer: jwtSignS3ObjectKey(key, +2h) → fileUrl
+    end
+    CallLayer-->>Handler: { input, response: JSON([{fileUrl, filename}...]), durationSeconds }
+    Handler-->>Tool: response + flowResponse
+```
+
+### 4.2 Agent 模式链路（agent/master/call.ts）
+
+```mermaid
+sequenceDiagram
+    participant Agent as Agent Master Call
+    participant Handler as master/call.ts 拦截
+    participant Dispatch as dispatchSandboxGetFileUrl()
+    participant CallLayer as callSandboxTool()

+    participant S3 as S3ChatSource.uploadChatFile()
+
+    Agent->>Handler: 调用 sandbox_get_file_url({ paths })
+    Handler->>Dispatch: dispatchSandboxGetFileUrl({ filePath, appId, ... })
+    Dispatch->>CallLayer: callSandboxTool({ toolName, rawArgs: {paths:[filePath]}, ... })
+    CallLayer->>SandboxProvider: readFileStream(filePath)
+    SandboxProvider-->>CallLayer: stream chunks
+    CallLayer->>S3: uploadChatFile({ expiredTime: +2h })
+    S3-->>CallLayer: { key }
+    CallLayer->>CallLayer: jwtSignS3ObjectKey(key, +2h)
+    CallLayer-->>Dispatch: { input, response, durationSeconds }
+    Dispatch-->>Handler: { response, nodeResponse }
+    Handler-->>Agent: { response, usages }
+```
+
+---
+
+## 五、错误处理
+
+| 错误场景 | 处理方式 |
+|----------|----------|
+| 文件不存在 | `readFileStream` 抛出异常，`callSandboxTool` 捕获后返回错误字符串，Agent 收到后可重试 |
+| 沙盒不可用 | `getSandboxClient` 失败，返回错误信息 |
+| S3 上传失败 | 捕获异常，返回错误信息 |
+| 文件过大 | ⚠️ **当前未限制**，文件内容先全部读入内存再上传（见六、待优化） |
+
+---
+
+## 六、待优化
+
+### 6.1 内存占用问题（当前实现缺陷）
+
+当前实现将沙盒文件全量读入内存后再上传 S3：
+
+```typescript
+// 当前：全量内存聚合
+const chunks: Uint8Array[] = [];
+for await (const chunk of stream) {
+  chunks.push(chunk);
+}
+const fileBuffer = Buffer.concat(chunks); // 大文件 OOM 风险
+```
+
+**问题**：大文件会导致内存暴涨，Tool Call 场景下 AI 可以任意触发，存在 DoS 风险。
+
+**优化方向一：文件大小限制**
+
+在聚合 chunks 过程中累计字节数，超过阈值立即中止：
+
+```typescript
+const MAX_FILE_SIZE = 50 * 1024 * 1024; // 50MB
+let totalSize = 0;
+for await (const chunk of stream) {
+  totalSize += chunk.byteLength;
+  if (totalSize > MAX_FILE_SIZE) {
+    throw new Error(`File too large (> ${MAX_FILE_SIZE / 1024 / 1024}MB)`);
+  }
+  chunks.push(chunk);
+}
+```
+
+**优化方向二：直接流式上传 S3（推荐）**
+
+绕过内存聚合，将 `readFileStream` 返回的 `AsyncIterable` 直接作为 S3 上传 body：
+
+```typescript
+const stream = instance.provider.readFileStream(filePath);
+// 需要 S3 client 支持传入 AsyncIterable/Stream 作为 body
+await this.client.uploadObject({ key, body: stream, contentType: '...' });
+```
+
+可行性取决于底层 S3 client（`@aws-sdk/client-s3` 的 `PutObjectCommand` 支持传入 `Readable` / `ReadableStream`）。需评估 `MinIO/custom` client 的支持情况后实施。
+
+---
+
