我想在我的网络界面上可视化 Neo4j 图形。所以我正在使用Netwok. Vis.js当我在这个例子中指定 JSON 文件时,它工作正常:

    var container = document.getElementById('graph');
    var options = {         
        clickToUse : true,
        edges: {

        },
        nodes: {

        }
    };


    var json= {
                "nodes":[
                    {
                        "id":"203437",
                        "label":"test",
                        "properties":{"id":"1","name":"test","uuid":"23e0a5f0-9f73-11e7-a866-7427e54567dc3"}

                    },
                    {
                        "id":"200624",
                        "label":"test 2",
                        "properties":{"id":"2","name":"test 2","uuid":"045ea890-9f72-11e7-a866-7427ea637dc3"}

                    }
                ],
                "relationships":[
                    {
                        "id":"164107",
                        "type":"IS_IN",
                        "from":200624,
                        "to":203437,
                        "properties":[]
                    }
                ]
            };

      var g = {
                nodes: json.nodes,
                edges: json.relationships
            }; 
    var network = new vis.Network(container, g, options);

但是当我尝试使用此JavaScript功能检索它时:

    getDataFromCypherQuery: function(request, callback) {
        var json = {
            "query": "MATCH path= (I:Person)-[IS_IN*1..1]-() WHERE I.name=~'.*" + request + ".*' RETURN path"
        };

        var res = $http.post( NEO4J_URL, json, config)
            .success(function(data) {
                if (callback && callback.success && typeof(callback.success) === 'function') {
                    callback.success(data);
                }
            })
            .error(function() {
                if (callback && callback.error && typeof(callback.error) === 'function') {
                    callback.error();
                }
            });             
        return res;
    }

它不起作用,因为JSON结果不一样并且不尊重vis.Network预期的结构。事实上,我用这个函数得到的结果是这样的:

  "nodes":[
            {"http://localhost:7474/db/data/node/203437"},
            {"http://localhost:7474/db/data/node/200624"}
          ]

  "relationships": [
            {"http://localhost:7474/db/data/relationship/164107"}
          ]

因此JSON,我没有获取格式的详细信息,而是获取到节点或关系的链接。我该如何解决?
