|
|
|
+
|
|
|
+## 1. 概述
|
|
|
+
|
|
|
+本文档说明工作流编辑器导出的 JSON 数据结构，供后端开发人员解析、存储和执行工作流数据时参考。
|
|
|
+
|
|
|
+## 2. 节点分类 (category)
|
|
|
+
|
|
|
+| 值 | 说明 |
|
|
|
+| --------- | ---------- |
|
|
|
+| basic | 基础节点 |
|
|
|
+| logic | 逻辑节点 |
|
|
|
+| database | 数据库节点 |
|
|
|
+| transform | 转换节点 |
|
|
|
+| tool | 工具节点 |
|
|
|
+
|
|
|
+## 3. 节点菜单的结构
|
|
|
+
|
|
|
+节点菜单用于定义前端可添加的节点列表，供前端渲染节点选择面板使用。
|
|
|
+
|
|
|
+### 3.1 节点分类列表 (categories)
|
|
|
+
|
|
|
+```json
|
|
|
+[
|
|
|
+ { "label": "基础节点", "value": "basic" },
|
|
|
+ { "label": "逻辑节点", "value": "logic" },
|
|
|
+ { "label": "数据库节点", "value": "database" },
|
|
|
+ { "label": "转换节点", "value": "transform" },
|
|
|
+ { "label": "工具节点", "value": "tool" }
|
|
|
+]
|
|
|
+```
|
|
|
+
|
|
|
+### 3.2 添加节点的菜单项结构
|
|
|
+
|
|
|
+每个节点菜单项包含三部分：`node`（节点基础信息）、`handle`（连接点）、`form`（表单配置）。
|
|
|
+
|
|
|
+```json
|
|
|
+{
|
|
|
+ "node": {
|
|
|
+ "type": "节点类型",
|
|
|
+ "data": {
|
|

|
|
+ },
|
|
|
+ "handle": [
|
|
|
+ { "type": "source", "position": "right" },
|
|
