php - neo4j-php-client 中的错误处理程序

Question

我下载并安装了 neo4j-php-client 和 neo4j 2.3.2。实际上一切正常，但我只是想知道为什么这个 php 客户端中没有错误处理程序？例如，如果密码查询中有错误，则不会抛出任何错误以便于捕获它。我通过网络搜索，但我找不到解决方案。

有人知道如何打开错误处理程序吗？

提前致谢。

我是neo4j-php-client.

当您向 Neo4j 发送查询时，它实际上是通过 Guzzle 发送的。

当然有一个用于处理异常的 try/catch 块，位于此处：

https://github.com/graphaware/neo4j-php-client/blob/master/src/HttpClient/GuzzleHttpClient.php#L76

如果您的密码查询出现错误，当然会抛出异常，该异常的类型为Neo4jException( https://github.com/graphaware/neo4j-php-client/blob/master/src/Exception/Neo4jException. php )

这是一个带有密码语法错误的简单代码，您可以看到抛出了异常：

<?php

require_once __DIR__ .'/vendor/autoload.php';

use Neoxygen\NeoClient\ClientBuilder;

$client = ClientBuilder::create()
    ->addConnection('default', 'http', 'localhost', 7474)
    ->setAutoFormatResponse(true)
    ->build();

$query = 'MATCH (n) RETURN x';

$result = $client->sendCypherQuery($query)->getResult();

Answer 2

感谢你的回答。问题似乎在我身上，经过几次测试后我发现 - 错误处理由 php 框架覆盖。
