在哪里为JanusGraph Gremlin Server配置GraphSONVersion.V1_0?

问题描述

我正在使用Tinuspop的JanusGraph 0.3.1和gremlin javascript驱动程序.我正在尝试访问图形，当我尝试在查询中检索valueMap()时，我正在获取类型信息.这不是我想要的，我正在寻找GraphSON响应的普通V1_0变体.请建议在哪里更新GraphSON版本配置?在服务器上?还是在创建客户端对象时在客户端上?

I am using JanusGraph 0.3.1 and gremlin javascript driver from Tinkerpop. I am trying to access the graph and when I try to retrieve the valueMap() in my queries, I am getting type information. Which is not what I was looking for I am looking for plain V1_0 variation of the GraphSON response. Please suggest where I shall update the GraphSON version configuration? on the server? or on the client while creating the client object?

在我的节点js服务的package.json中，我已经:"gremlin": "^2.6.0",

In my node js service's package.json I've:"gremlin": "^2.6.0",

我的服务器配置为:

我将在Node JS应用中创建客户端，如下所示:

I am creating the client in my Node JS app as follows:

const Gremlin = require('gremlin');
req.graph =Gremlin.createClient(graphPort, graphHost, {graphSONVersion:'V1_0'});

推荐答案

我只需要评论
