# Neo4j 接口后端需求
|
||
|
||
## 需求说明
|
||
|
||
前端 Neo4j 图谱功能已完成，后端接口需要匹配前端调用。
|
||
|
||
---
|
||
|
||
## 1. 新增 `/neo4j/graphs` 接口
|
||
|
||
### 接口地址
|
||
```
|
||
POST /neo4j/graphs
|
||
```
|
||
|
||
### 请求参数
|
||
```json
|
||
{
|
||
"uri": "bolt://localhost:7687",
|
||
"username": "neo4j",
|
||
"password": "password",
|
||
"database": "neo4j"
|
||
}
|
||
```
|
||
|
||
| 参数 | 类型 | 必填 | 说明 |
|
||
|------|------|------|------|
|
||
| uri | string | 是 | Neo4j 连接地址，如 bolt://localhost:7687 |
|
||
| username | string | 是 | 用户名 |
|
||
| password | string | 是 | 密码 |
|
||
| database | string | 否 | 数据库名（默认 neo4j） |
|
||
|
||
### 返回参数
|
||
```json
|
||
{
|
||
"success": true,
|
||
"graphs": {
|
||
"labels": [
|
||
{"name": "User", "count": 1523},
|
||
{"name": "Order", "count": 856}
|
||
],
|
||
"relationshipTypes": [
|
||
{"name": "KNOWS", "count": 2341},
|
||
{"name": "BOUGHT", "count": 5678}
|
||
]
|
||
}
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 2. 修改路由路径
|
||
|
||
### 当前状态
|
||
- `/database/neo4j/nodes` → 需要改为 → `/neo4j/nodes`
|
||
- `/database/neo4j/relationships` → 需要改为 → `/neo4j/relationships`
|
||
|
||
---
|
||
|
||
## 总结
|
||
|
||
后端需要修改以下内容：
|
||
|
||
1. **新增** `/neo4j/graphs` 接口
|
||
2. **修改** `/database/neo4j/nodes` → `/neo4j/nodes`
|
||
3. **修改** `/database/neo4j/relationships` → `/neo4j/relationships`

## 附：前端 API 调用示例
|
||
|
||
```javascript
|
||
// 获取图谱概览
|
||
fetch('/neo4j/graphs', {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/json' },
|
||
body: JSON.stringify({
|
||
uri: 'bolt://10.10.10.189:7687',
|
||
username: 'neo4j',
|
||
password: 'neo4j',
|
||
database: 'neo4j'
|
||
})
|
||
})
|
||
|
||
// 获取节点详情
|
||
fetch('/neo4j/nodes', {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/json' },
|
||
body: JSON.stringify({
|
||
uri: 'bolt://10.10.10.189:7687',
|
||
username: 'neo4j',
|
||
password: 'neo4j',
|
||
label: 'User',
|
||
limit: 10
|
||
})
|
||
})
|
||
|
||
// 获取关系详情
|
||
fetch('/neo4j/relationships', {
|
||
method: 'POST',
|
||
headers: { 'Content-Type': 'application/json' },
|
||
body: JSON.stringify({
|
||
uri: 'bolt://10.10.10.189:7687',
|
||
username: 'neo4j',
|
||
password: 'neo4j',
|
