php - Elasticsearch ~2.0 php - 无法建立连接 - 数组到字符串转换错误

Question

按照elasticsearch文档，我安装了当前的php库，即2.0，并且我这样做了

$hosts = [
  // This is effectively equal to: "https://username:password!#$?*<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6302010023050c0c4d000c0e" rel="noreferrer noopener nofollow">[email protected]</a>:9200/"
  [
    'host' => 'foo.com',
    'port' => '9200',
    'scheme' => 'https',
    'user' => 'username',
    'password' => 'password!#$?*abc'
  ],

  // This is equal to "http://localhost:9200/"
  [
    'host' => 'localhost',    // Only host is required
  ]
];

$client = ClientBuilder::create()  // Instantiate a new ClientBuilder
              ->setHosts($hosts)   // Set the hosts
              ->build();

但它从 buildConnectionsFromHosts 方法抛出数组到字符串转换错误。我无法建立连接。

我检查了代码，发现没有代码来处理以数组形式给出的主机。这是库中的错误还是我遗漏了某些内容？

谢谢。

解决方案

主机选项中的“password”键应替换为“pass”。

需要修改库中的ClientBuilder.php文件。下面的代码不在elasticsearch-php 2.0 ClientBuilder.php 文件中，但在其主分支中。

我替换了buildConnectionsFromHosts方法

/**
         * @param array $hosts
         *
         * @throws \InvalidArgumentException
         * @return \Elasticsearch\Connections\Connection[]
         */
        private function buildConnectionsFromHosts($hosts)
        {
            if (is_array($hosts) === false) {
                $this->logger->error("Hosts parameter must be an array of strings, or an array of Connection hashes.");
                throw new InvalidArgumentException('Hosts parameter must be an array of strings, or an array of Connection hashes.');
            }

            $connections = [];
            foreach ($hosts as $host) {
                if (is_string($host)) {
                    $host = $this->prependMissingScheme($host);
                    $host = $this->extractURIParts($host);
                } else if (is_array($host)) {
                    $host = $this->normalizeExtendedHost($host);
                } else {
                    $this->logger->error("Could not parse host: ".print_r($host, true));
                    throw new RuntimeException("Could not parse host: ".print_r($host, true));
                }
                $connections[] = $this->connectionFactory->create($host);
            }

            return $connections;
        }

并添加了normalizeExtendedHost方法

 /**
     * @param $host
     * @return array
     */
    private function normalizeExtendedHost($host) {
        if (isset($host['host']) === false) {
            $this->logger->error("Required 'host' was not defined in extended format: ".print_r($host, true));
            throw new RuntimeException("Required 'host' was not defined in extended format: ".print_r($host, true));
        }

        if (isset($host['scheme']) === false) {
            $host['scheme'] = 'http';
        }
        if (isset($host['port']) === false) {
            $host['port'] = '9200';
        }
        return $host;
    }
