php - 当我在 php 中尝试 Solr 时出现问题

Question

当我在 PHP 中运行示例时遇到问题，代码如下:

<?php
  require_once( 'SolrPhpClient/Apache/Solr/Service.php' );

  // 
  // 
  // Try to connect to the named server, port, and url
  // 
  $solr = new Apache_Solr_Service( 'localhost', '8983', '/solr/' );

  if ( ! $solr->ping() ) {
    echo 'Solr service not responding.';
    exit;
  }

  //
  //
  // Create two documents to represent two auto parts.
  // In practice, documents would likely be assembled from a 
  //   database query. 
  //
  $parts = array(
    'spark_plug' => array(
      'partno' => 1,
      'name' => 'Spark plug',
      'model' => array( 'Boxster', '924' ),
      'year' => array( 1999, 2000 ),
      'price' => 25.00,
      'inStock' => true,
    ),
    'windshield' => array(
      'partno' => 2,
      'name' => 'Windshield',
      'model' => '911',
      'year' => array( 1999, 2000 ),
      'price' => 15.00,
      'inStock' => false,
    )
  );

  $documents = array();

  foreach ( $parts as $item => $fields ) {
    $part = new Apache_Solr_Document();

    foreach ( $fields as $key => $value ) {
      if ( is_array( $value ) ) {
        foreach ( $value as $datum ) {
          $part->setMultiValue( $key, $datum );
        }
      }
      else {
        $part->$key = $value;
      }
    }

    $documents[] = $part;
  }

  //
  //
  // Load the documents into the index
  // 
  try {
    $solr->addDocuments( $documents );
    $solr->commit();
    $solr->optimize();
  }
  catch ( Exception $e ) {
    echo $e->getMessage();
  }

  //
  // 
  // Run some queries. Provide the raw path, a starting offset
  //   for result documents, and the maximum number of result
  //   documents to return. You can also use a fourth parameter
  //   to control how results are sorted and highlighted, 
  //   among other options.
  //
  $offset = 0;
  $limit = 10;

  $queries = array(
    'partno: 1 OR partno: 2',
    'model: Boxster',
    'name: plug'
  );

  foreach ( $queries as $query ) {
    $response = $solr->search( $query, $offset, $limit );

    if ( $response->getHttpStatus() == 200 ) { 
      // print_r( $response->getRawResponse() );

      if ( $response->response->numFound > 0 ) {
        echo "$query <br />";

        foreach ( $response->response->docs as $doc ) { 
          echo "$doc->partno $doc->name <br />";
        }

        echo '<br />';
      }
    }
    else {
      echo $response->getHttpStatusMessage();
    }
  }
?>

但是一旦运行就会出现如下错误:

'400' Status: Bad Request
Fatal error: Uncaught exception 'Apache_Solr_HttpTransportException' with message ''400' Status: Bad Request' in C:\software\study\php\xampp\xampp\htdocs\SolrPhpClient\Apache\Solr\Service.php:338 Stack trace: #0 C:\software\study\php\xampp\xampp\htdocs\SolrPhpClient\Apache\Solr\Service.php(1170): Apache_Solr_Service->_sendRawGet('http://localhos...') #1 C:\software\study\php\xampp\xampp\htdocs\solr1.php(98): Apache_Solr_Service->search('partno: 1 OR pa...', 0, 10) #2 {main} thrown in C:\software\study\php\xampp\xampp\htdocs\SolrPhpClient\Apache\Solr\Service.php on line 338

可能是什么问题。

感谢所有帮助。

Answer 1

您可能有 (a) 错误的查询语法，或 (b) 错误配置的索引。

检查您的索引

看起来您有零件号、型号等字段。您需要确保在您的 schema.xml 中配置了这些字段.我可能猜想您没有在那里创建它们，因此您的文档提交失败，或者您有一个模型字段，但它不是多值的。

如果它通过了文件提交，那么你可能有一个查询问题......

调试查询

调试查询的最简单方法是在发送之前回显查询。在这种情况下:

 echo $query

从中获取输出并点击:

 http://localhost:8983/solr/select?q=<query>

(echo 语句中的查询在哪里)。

您可能会遇到 400 错误。我的猜测是你在某个地方有一个错误的字段名称，或者在你的查询中使用了无效的语法。如果您可以发布 $query，则可以更轻松地帮助解决问题。
