JSON对象解析:REST API neo4j密码响应中具有多个节点的多行 [英] JSON object parsing : multiple rows with multiple nodes in a REST API neo4j cypher response
本文介绍了JSON对象解析:REST API neo4j密码响应中具有多个节点的多行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在通过REST API处理JSON Neo4j响应时，我想尽力了解如何访问返回的值， 当我的结果是一列两行时.每行依次包含多个节点.
When playing around with JSON Neo4j response over REST API, i am trying to break my head to understand how to should i access a value returned, when my result is having one column and 2 rows . Each row in turn contains multiple nodes.
查询(给我一个旅行计划):
the query (gives me a travel plan) :
MATCH (a:LandMark {name:'Acharya College' }),(d:AirPort {name:'Frankfurt International Airport'})
MATCH p1 = allShortestPaths((a)-[:STOPS_AT*]-(d))
WITH p1, FILTER(j IN NODES(p1) WHERE(j in nodes(p1)) ) AS buses
RETURN buses
我理解的响应是一个嵌套数组，但是我无法弄清楚哪些是访问值的索引.
the response i understand is a nested array one, but i am unable to figure out which are the indexes to access the values.
警报(JSON.stringify(data，null，4));给出:
the alert(JSON.stringify(data, null, 4)); gives:

推荐答案
I know you're using php and that your question is related to this one : Parsing a neo4j JSON object in javascript
为什么不利用现有的驱动程序来减轻响应解析的负担.
Why don't you take advantage of the existing drivers that will remove you the burden of the response parsing.
以下是使用 neoclient 的示例:
composer require neoxygen/neoclient
-
$client = ClientBuilder::create()
->addDefaultLocalConnection()
->build();
// Sending your query :
$query = "MATCH (a:LandMark {name:'Acharya College' }),(d:AirPort {name:'Frankfurt International Airport'})
MATCH p1 = allShortestPaths((a)-[:STOPS_AT*]-(d))
WITH p1, FILTER(j IN NODES(p1) WHERE(j in nodes(p1)) ) AS buses
RETURN buses";
$result = $client->sendCypherQuery($query)->getResult();
// Getting the buses
$buses = $result->get('buses'); // Just specify the return alias desired
// Returns you a collection of buses
// Passing what you want to your frontend :
$response = [];
foreach ($buses as $bus) {
$response[] = [
'bus_name' => $bus->getProperty('name'),
'bus_id' => $bus->getProperty('id')
];
return json_encode($response);
在您的JavaScript中，您只需要遍历响应即可；-)
And in your javascript you only need to iterate over the response ;-)
