Question

过去我们使用以下代码连接到neo：

use GraphAware\Neo4j\Client\ClientBuilder;
 $neo4j  = ClientBuilder::create()
            -> addConnection('default', $neo_ip)
            -> setDefaultTimeout($neo_timeout)
            -> build();

setDefaultTimeout已被弃用，默认卷曲超时为5秒，对于某些查询而言不够长。

我们可以使用螺栓，但螺栓连接中的setDefaultTimeout也可能会被弃用。

use GraphAware\Neo4j\Client\ClientBuilder;
$neo4j  = ClientBuilder::create()
           -> addConnection('bolt',    $neo_bolt_ip)
            -> setDefaultTimeout($neo_timeout)
            -> build();

在http连接上设置超时的新方法如下：

use GraphAware\Neo4j\Client\ClientBuilder;
use Http\Client\Curl\Client;
$options = [
        CURLOPT_CONNECTTIMEOUT => 99, // The number of seconds to wait while trying to connect.
        CURLOPT_SSL_VERIFYPEER => false   // Stop cURL from verifying the peer's certificate
    ];
    $httpClient = new Client(null, null, $options);
    $config = \GraphAware\Neo4j\Client\HttpDriver\Configuration::create($httpClient);

    $neo4j  = ClientBuilder::create()
            -> addConnection('default', $neo_ip, $config)
            -> build();

然而，使用这种新方法，我得到Unsupported Media Type例外如果有人对此有所了解，请分享。

现在我们可以使用以下设置超时：

$neo_timeout = 999;
$neo_ip = "http://user:passwd@127.0.0.1:7474";
use GraphAware\Neo4j\Client\ClientBuilder;
$httpClient = \Http\Adapter\Guzzle6\Client::createWithConfig(['timeout'=>$neo_timeout]);
$config = \GraphAware\Neo4j\Client\HttpDriver\Configuration::create($httpClient);

$neo4j  = ClientBuilder::create()
        -> addConnection('default', $neo_ip, $config)
        -> build();

已经发布了使用php-http / curl-client的修复方法见：https://github.com/graphaware/neo4j-php-client/pull/114
