在neo4j中使用REST API时出现404错误

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" 
    } 
}, 

获得响应：

错误：空 体：

      "content-type":"application/json", 
      "content-length":144 
      } 
     } 
} 

请，谁能帮助我这个？

您从url和to路径中缺少/node。

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" 
    } 
}
