下面的测试用例(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

这是我 var_dump 时的 $client:

我不知道如何解释这个或者哪里出了问题。
我的数据库在 neo4j 浏览器客户端中正常运行。
据我所知,graphaware 已按照 网站上的说明。
我已经测试过,错误发生在运行查询时, 不是在创建客户端的时候(即使这不是 错误清楚地指出了)。
如果我将查询直接复制/粘贴到 neo4j 浏览器客户端 然后它按预期工作。
知道我为什么会收到此错误吗?
最佳答案
根据 GraphAware PHP Client你似乎没有使用最新版本,所以你需要更新,或者你点击了the empty array bug (例如,您的问题是您没有发送 Content-Type:application/json,这似乎只能使用 GraphAware\Neo4j\中的函数 prepareRequest 进行设置客户端\HttpDriver\ session )。还要查看您的查询语法,因为它似乎已在 Install instructions 中弃用。在the developer documentation对于 Neo4j。
