<!-- Answer --> 你可以这样在 Dify 工作流的 HTTP 节点配置访问 HugeGraph，执行 g.V() 查询所有顶点和连接关系： **1. API** ``` http://server:8080/gremlin ``` （server 替换为你的 HugeGraph 主机名或 IP） **2. HEADERS** ```json { "Content-Type": "application/json" // 如果 HugeGraph 开启了鉴权，还需要加 // "Authorization": "Basic base64(user:password)" 或 "Authorization": "Bearer your_token" } ``` **3. PARAMS** 无需填写（留空即可）。如果用 GET 方式，可以加参数 `gremlin=g.V()`，但推荐用 POST。 **4. BODY** ```json { "gremlin": "g.V()", "bindings": {}, "language": "gremlin-groovy", "aliases": { "graph": "hugegraph", "g": "__g_hugegraph" } } ``` - `gremlin`：Gremlin 查询语句，g.V() 查询所有顶点，g.E() 查询所有边。 - `aliases`：指定图空间和遍历变量，推荐如上填写。 **返回结果**是 JSON，所有顶点和属性在 `result.data` 数组里。你可以在 Dify 后续节点用 JSONPath 提取需要的内容。 **常见问题排查：** - 如果接口 401/403，检查是否需要认证（Authorization）。 - 如果 404，确认 API 路径和端口号。 - 如果返回乱码，确认 Content-Type 和 Accept 都为 application/json。 - 如果数据量大，建议加分页或限制。 官方文档参考：[HugeGraph Gremlin REST API](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/cn/docs/clients/restful-api/gremlin.md) 如需查询所有边，把 gremlin 改成 `"g.E()"` 即可。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
