使用 Lumen 和 Neo Eloquent OGM 从 Neo4j 中检索日期时间
Retrive DateTime from Neo4j using Lumen and NeoEloquent OGM
上下文
我正在创建一个 api 休息，它连接到一个已经由节点和边缘填充的图形数据库，该节点和边缘描述事件和展览在几个博物馆内的位置，这些博物馆由区域表征。特别是展览和区域之间有一些边缘，具有开始时间和坐标等属性。
开始时间是一个符合DateTime neo4j格式的属性，下面是一个例子：
{
"start": "2018-01-01T00:00:01.300Z",
"coordinate": [
0,
0,
0
]
}
我创建边缘的方式是：
CREATE (exhibit)-[:belongs_to {start:datetime('2018-01-01T00:00:01.300Z')}]->(zone)
其中 exhibit 和 zone 分别是节点 ID。
问题
我想从特定边检索开始 [=37=]，但这是结果：
Unsupported property type: class java.time.ZonedDateTime
代码
findZone 函数产生问题：
<?php
namespace App;
use Vinelab\NeoEloquent\Eloquent\Model;
use App\Http\Controllers\ZoneController;
class Exhibit extends Model{
protected $label = 'Exhibit';
protected $fillable = [];
protected $hidden = [];
public function zones(){
return $this->belongsToMany('App\Zone', 'belongs_to');
}
public static function findZone($exhibit){
$edge = $exhibit->zones()->edge(ZoneController::showZoneByName("Parlatorio"));
return $edge->start;
}
}
我尝试只给边缘坐标 属性 并且当我用坐标替换开始 属性 时函数工作。

我也遇到了这个问题，但未能找到您想要的解决方法。据我所知，它在 neoeloquent 库本身中。但是我想出了一个不理想的替代方案，因为能够使用库来完成它会更好但它有效。
我写了一个 RawQueryService，它可以采用原始 Neo4j 查询并将输出检索为关联数组。
RawQueryService如下：
<?php
namespace App\Services;
use Illuminate\Support\Facades\DB;
class RawQueryService
{
public static function executeRawQuery(string $query, $noProcessing=false) {
$result = DB::select($query);
$resultArray = array();
foreach($result as $row){
$result = $row['n'];
array_push($resultArray, $result);
}
return $resultArray;
}
}
然后检索开始时间：
$start = \App\Services\RawQueryService::executeRawQuery(
"match(n) where n.title=\"".$title."\" return toString(n.start)");
它在内部将日期时间转换为字符串，因此 Neo4j 库不会收到 IllegalArgumentException。
希望对您有所帮助。
我一直在解决这个问题，发现在服务器 REST API 中序列化 datetime 属性存在问题。根据 http 与 bolt 和查询类型的不同，会生成一些不同的错误，但是当 datetime 属性从响应中删除时，它们就会消失。
服务器的 v3.5.0 已针对 HTTP 请求修复它。我还没有验证这个版本的螺栓。
我的调查和解决方案的更多详细信息位于 https://github.com/neo4jrb/neo4j/issues/1522（ruby gem 客户端）。 v3.4.1 和 3.4.6 都存在这个问题。

我也遇到了这个问题，但未能找到您想要的解决方法。据我所知，它在 neoeloquent 库本身中。但是我想出了一个不理想的替代方案，因为能够使用库来完成它会更好但它有效。
我写了一个 RawQueryService，它可以采用原始 Neo4j 查询并将输出检索为关联数组。
RawQueryService如下：
<?php
namespace App\Services;
use Illuminate\Support\Facades\DB;
class RawQueryService
{
public static function executeRawQuery(string $query, $noProcessing=false) {
$result = DB::select($query);
$resultArray = array();
foreach($result as $row){
$result = $row['n'];
array_push($resultArray, $result);
}
return $resultArray;
}
}
然后检索开始时间：
$start = \App\Services\RawQueryService::executeRawQuery(
"match(n) where n.title=\"".$title."\" return toString(n.start)");
它在内部将日期时间转换为字符串，因此 Neo4j 库不会收到 IllegalArgumentException。
希望对您有所帮助。
我一直在解决这个问题，发现在服务器 REST API 中序列化 datetime 属性存在问题。根据 http 与 bolt 和查询类型的不同，会生成一些不同的错误，但是当 datetime 属性从响应中删除时，它们就会消失。
v3.5.0 已针对 HTTP 请求修复它。我还没有验证这个版本的螺栓。
我的调查和解决方案的更多详细信息位于 https://github.com/neo4jrb/neo4j/issues/1522（ruby gem 客户端）。 v3.4.1 和 3.4.6 都存在这个问题。
