以下测试用例(假设密码正确)

<?php
    require_once "vendor/autoload.php";
    use GraphAware\Neo4j\Client\ClientBuilder;
    $client = ClientBuilder :: create() -> addConnection("default", "http://neo4j:Password@localhost:7474") -> build();
    $query  = "MATCH (u:User)
               RETURN u";
    $result = $client -> run($query);
    $user = $result -> firstRecord() -> values()[0];
?>

给我以下错误:

PHP Fatal error:  Uncaught GuzzleHttp\\Exception\\ClientException: Client error: `POST http://neo4j:***@localhost:7474/db/data/transaction/commit` resulted in a `400 Bad Content-Type header value: ''` response in /var/www/html/vendor/guzzlehttp/guzzle/src/Exception/RequestException.php:113

我有一个cypher查询,产生以下结果:

A  1
A  2
A  3
B  1
B  2

我想将第一个属性的相同值组合起来并总结它们,结果将是:

A  6
B  3
