Graph 不能在合并模式中使用参数映射

我得到错误参数映射不能用于合并模式。我如何解决此错误。我正在使用下面的代码。我非常感谢任何帮助。提前感谢

'MERGE (u:Person {names}) RETURN u ';

及

完整代码：

<?php

$data2='{
  "names" : [{
    "name" : "Keanu Reeves1",
    "role" : "Neo1"
  },
  {
    "name" : "Keanu Reeves2",
    "role" : "Neo2"
  },
  {
    "name" : "Keanu Reeves3",
    "role" : "Neo3"
  }]
}';


$data ='MERGE (u:Person {names}) RETURN u';


$data2=json_decode($data2);


$data = array("query" =>$data,"params"=>$data2 );
$data_string = json_encode($data);


print_r($data_string);
//print_r($data2);
$ch = curl_init('http://192.....:7474/db/data/cypher');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($data_string))
);

print_r ($ch);

$result = curl_exec($ch);

print_r($result);

?>

不幸的是，由于查询规划的原因，这些映射不能用于合并。与sql中的动态表列相同

不过，您可以做的是：

create constraint on (n:Label) assert n.id is unique;

MERGE (n:Label {id:{map}.id})
ON CREAETE SET n={map}

create constraint on (n:Label) assert n.id is unique;

MERGE (n:Label {id:{map}.id})
ON CREAETE SET n={map}
