在neo4j

Question

这里我试图在neo4j中执行shortestPath算法。

{
    method: 'POST',
    json:true,
    url: 'http://neo4j:admin@localhost:7474/db/data/81/path',
    body:{
        "to" : '/db/data/84',
        "max_depth" : 2,
        "relationships" : {
            "type" : "Meet",
            "direction" : "out"
        },
        "algorithm" : "shortestPath"
    }
},

获得回复：

           }
       }
}

拜托，有人可以帮我解决这个问题吗？

您的/node和url路径中缺少to。

试试这个：

{
    method: 'POST',
    json:true,
    url: 'http://neo4j:admin@localhost:7474/db/data/node/81/path',
    body:{
        "to" : '/node/84',
        "max_depth" : 2,
        "relationships" : {
            "type" : "Meet",
            "direction" : "out"
        },
        "algorithm" : "shortestPath"
    }
}
