你的 curl 报错 {"exception":"","message":"body could not be
parsed","cause":""},根本原因是 POST 的 JSON 格式不被 HugeGraph Gremlin API 正确解析,尤其是在
Windows 下用 curl 时,-d 参数的 JSON
字符串容易格式出错(比如单双引号、转义、编码等问题)[参考1](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-api/src/main/java/org/apache/hugegraph/api/job/GremlinJob.java)
[参考2](https://github.com/apache/incubator-hugegraph/pull/2894)。
**最安全的做法:**
1. 把 JSON 请求体写到一个文件(比如 body.json),内容如下(注意全部是英文半角双引号):
```json
{
"gremlin": "g.V()",
"bindings": {},
"language": "gremlin-groovy",
"aliases": {
"graph": "hugegraph",
"g": "__g_hugegraph"
}
}
```
2. 用 curl 发送(Windows 命令行):
```sh
curl -X POST "http://192.168.60.17:8080/gremlin" -H "Content-Type:
application/json" -d @body.json
```
这样可以避免命令行转义和引号问题,确保服务器能正确解析 JSON。
**常见坑:**
- -d 后面直接写 JSON 字符串时,Windows 下单双引号、转义、编码容易出错,导致 body 不是合法 JSON。
- Content-Type 必须是 application/json。
- API 路径和端口必须和实际服务一致(你用的 8080 没问题)。
- 如果还是报错,建议用 curl -v 查看实际请求内容,或者用 Postman 测试。
**Dify HTTP 节点配置:**
- API: http://192.168.60.17:8080/gremlin
- HEADERS: Content-Type: application/json
- PARAMS: 留空
- BODY: 和上面 body.json 内容一致,必须是严格 JSON 格式
**如果还有问题,请贴出你实际用的 curl 命令、body.json 文件内容和完整返回信息,我可以帮你定位是哪一步格式有误。**
