Neo4j PHP绘图软件&x27；415不支持的媒体类型'；

以下测试用例（假设密码正确）

这是我卸载$client时的$client：

object(GraphAware\Neo4j\Client\Client)#7 (2) {
  ["connectionManager":protected]=>
  object(GraphAware\Neo4j\Client\Connection\ConnectionManager)#2 (2) {
    ["connections":"GraphAware\Neo4j\Client\Connection\ConnectionManager":private]=>
    array(1) {
      ["default"]=>
      object(GraphAware\Neo4j\Client\Connection\Connection)#4 (5) {
        ["alias":"GraphAware\Neo4j\Client\Connection\Connection":private]=>
        string(7) "default"
        ["uri":"GraphAware\Neo4j\Client\Connection\Connection":private]=>
        string(38) "http://neo4j:Password@localhost:7474"
        ["driver":"GraphAware\Neo4j\Client\Connection\Connection":private]=>
        object(GraphAware\Neo4j\Client\HttpDriver\Driver)#6 (2) {
          ["uri":protected]=>
          string(38) "http://neo4j:Password@localhost:7474"
          ["config":protected]=>
          object(GraphAware\Neo4j\Client\HttpDriver\Configuration)#5 (1) {
            ["timeout":protected]=>
            int(5)
          }
        }
        ["session":"GraphAware\Neo4j\Client\Connection\Connection":private]=>
        NULL
        ["timeout":"GraphAware\Neo4j\Client\Connection\Connection":private]=>
        int(5)
      }
    }
    ["master":"GraphAware\Neo4j\Client\Connection\ConnectionManager":private]=>
    NULL
  }
  ["eventDispatcher":protected]=>
  object(Symfony\Component\EventDispatcher\EventDispatcher)#8 (2) {
    ["listeners":"Symfony\Component\EventDispatcher\EventDispatcher":private]=>
    array(0) {
    }
    ["sorted":"Symfony\Component\EventDispatcher\EventDispatcher":private]=>
    array(0) {
    }
  }
}

我不知道如何解释这一点，也不知道是什么错

• 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
  正确安装 网站上的说明

• 我已经测试过，错误发生在运行查询时， 不是在创建客户机时（即使这不是 由错误明确指示）

• 如果我将查询直接复制/粘贴到neo4j浏览器客户端 然后它就如预期的那样工作了

知道我为什么会出现这个错误吗？

我看到了同样的问题：(

我将其调试到HttpDriver/Session.php flush函数中，我认为头的设置不正确：

public function flush(Pipeline $pipeline)
    {
        $request = $this->prepareRequest($pipeline);
        try {
            $response = $this->httpClient->sendRequest($request);

value of request
[headers:GuzzleHttp\Psr7\Request:private] => Array
        (
            [Host] => Array
                (
                    [0] => localhost:7474
                )

            [0] => Array
                (
                    [X-Stream] => 1
                    [Content-Type] => application/json
                )

        )

非常确定请求应该是这样的：

Array
        (
            [Host] => Array
                (
                    [0] => localhost:7474
                )
            [X-Stream] => 1
            [Content-Type] => application/json
        )

为了解决这个问题，我修改了PrepareRequest函数以生成正确的头

// Line 197
$headers = [
  'X-Stream' => true,
  'Content-Type' => 'application/json'
];

Array
        (
            [Host] => Array
                (
                    [0] => localhost:7474
                )
            [X-Stream] => 1
            [Content-Type] => application/json
        )

// Line 197
$headers = [
  'X-Stream' => true,
  'Content-Type' => 'application/json'
];
