<!-- Answer --> 你的 Dify HTTP 节点报 “Reached maximum retries (0) for URL http://server:8080/gremlin”，根本原因是 API 地址里的 `server` 必须替换成 HugeGraph 实际服务器的 IP 地址或主机名，不能直接写 `server` 字符串，否则 Dify 节点无法解析/连接，导致网络请求直接失败（不是权限或 API 配置问题）[参考](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/cn/docs/clients/gremlin-console.md)。 **正确配置方法如下：** 1. **API** ``` http://<实际IP或主机名>:8080/gremlin ``` 例如：`http://192.168.1.100:8080/gremlin` 或 `http://your-server-hostname:8080/gremlin` 2. **HEADERS** ```json { "Content-Type": "application/json" } ``` 未开启鉴权时无需 Authorization。 3. **PARAMS** 留空即可。 4. **BODY** ```json { "gremlin": "g.V()", "bindings": {}, "language": "gremlin-groovy", "aliases": { "graph": "hugegraph", "g": "__g_hugegraph" } } ``` **排查建议：** - 用 curl 或 Postman 在 Dify 节点所在主机上测试： ``` curl -X POST "http://<实际IP>:8080/gremlin" -H "Content-Type: application/json" -d '{"gremlin":"g.V()","bindings":{},"language":"gremlin-groovy","aliases":{"graph":"hugegraph","g":"__g_hugegraph"}}' ``` 能返回数据说明网络没问题，否则请检查网络、防火墙、端口映射等。 - 如果还是报错，确认 Dify 节点和 HugeGraph 服务是否在同一内网/容器，端口 8080 是否开放，主机名/IP 是否能互通。 - 只要 API 地址写对，网络可达，未开启鉴权时无需额外配置，POST body 如上即可。 如还有问题，建议贴出 curl 的详细报错信息和你实际填写的 API 地址，我可以帮你定位是哪一步网络或配置有误。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fhugegraph).* --- Docs are dead.
