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

在elasticsearch文档之后，我安装了当前的php库ie 2.0，我做到了这一点

$hosts = [
  // This is effectively equal to: "https://username:password!#$?*abc@foo.com: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();

但是它从buildConnectionsFromHosts方法引发了数组到字符串的转换错误。我无法建立连接

我检查了代码，发现没有以数组形式提供的代码来处理主机。这是库中的错误还是我遗漏了什么

谢谢。

解决方案

主机选项中的“密码”键应替换为“密码”

需要修改库中的ClientBuilder.php文件。以下代码不在elasticsearch php 2.0 ClientBuilder.php文件中，而是在其主分支中

我替换了从主机构建连接的方法

/**
         * @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;
        }

 /**
     * @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;
    }

并添加了normalizeExtendedHost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;
        }

 /**
     * @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;
    }

这是elasticsearch网站提供的文档中的配置示例。请看一看这个。如果你真的在遵循指南，在我看来，你正在打开一个https连接，而你的主机没有启用一个。如果这是您在本地使用的实际配置，那么不管怎样，它都不会工作，因为您将无法连接到foo上的elasticsearch。com@Bjorn我知道这个事实，这是我复制的示例配置，因为我无法在这里显示我的实际配置。至少这不会因此引发数组到字符串的转换错误。
