+# 接口响应体说明
+
+## 基础结构
+
+| 字段 | 类型 | 描述 |
+| --- | --- | --- |
+| status | String | 枚举值：Sucess/Failed。<br>代表请求是否正常由沙箱执行完成。 |
+| message | String | 响应信息。 |
+| error | String | 表示当status=Failed时的错误描述信息。 |
+| result | Object | 请求执行结果。根据具体功能，结构有所差异。 |
+| └code | Integer | 响应状态码。参考下方状态码定义。 |
+| └failure\_reason | String | 当code=5xxx时，包含一些额外的错误信息。 |
+| └... |  | 根据不同接口，扩展信息有所不同。 |
+
+### 响应状态码定义
+
+| **值** | **描述** |
+| --- | --- |
+| 2xxx | 命令执行成功 |
+| 5xxx | 服务端异常。该场景建议用户进行重试。 |
+| 6xxx | 命令执行错误 |
+
+## result扩展信息定义
+
+### execute/run\_in\_session
+
+| 字段 | 类型 | 描述 |
+| --- | --- | --- |
+| exit\_code | Integer | 命令执行退出码。<br>特殊退出码：-1（超时/网络/会话失效） |
+| stdout | String | 命令执行标准输出 |
+| stderr | String | 命令执行标准错误 |
+
+### create\_session
+
+| 字段 | 类型 | 描述 |
+| --- | --- | --- |
+| output | String | session创建结果。 |
+| session\_type | String | session类型。<br>枚举值：<br>*   bash |
+
+### close\_session
+
+| 字段 | 类型 | 描述 |
+| --- | --- | --- |
+| session\_type | String | session类型。<br>枚举值：<br>*   bash |
+
+### upload
+
+| **字段** | **类型** | **描述** |
+| --- | --- | --- |
+| success | Boolean | 文件上传是否成功。 |
+| message | String | 上传结果信息。 |
+| file\_name | String | 文件名 |
+
+现有响应结构固定返回默认值，需要调整。
