我正在浏览solr的php文档，并想尝试基本的例子。但是，当我在现有项目中尝试以下代码时，未收到预期的输出并返回空白页。
<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$doc = new SolrInputDocument();
$doc->addField('ID', 334455);
//$doc->addField('cat', 'Software');
//$doc->addField('cat', 'Lucene');
$updateResponse = $client->addDocument($doc);
print_r($updateResponse->getResponse());
?>
bootstrap.php是这样的：
/* Domain name of the Solr server */
define('SOLR_SERVER_HOSTNAME', 'localhost');
/* Whether or not to run in secure mode */
define('SOLR_SECURE', false);
/* HTTP Port to connection */
define('SOLR_SERVER_PORT', ((SOLR_SECURE) ? 8443 : 8080));
/* HTTP Basic Authentication Username */
define('SOLR_SERVER_USERNAME', 'admin');
/* HTTP Basic Authentication password */
define('SOLR_SERVER_PASSWORD', 'changeit');
/* HTTP connection timeout */
/* This is maximum time in seconds allowed for the http data transfer operation.Default value is 30 seconds */
define('SOLR_SERVER_TIMEOUT', 10);
/* File name to a PEM-formatted private key + private certificate (concatenated in that order) */
define('SOLR_SSL_CERT', 'certs/combo.pem');
/* File name to a PEM-formatted private certificate only */
define('SOLR_SSL_CERT_ONLY', 'certs/solr.crt');
/* File name to a PEM-formatted private key */
define('SOLR_SSL_KEY', 'certs/solr.key');
/* Password for PEM-formatted private key file */
define('SOLR_SSL_KEYPASSWORD', 'StrongAndSecurePassword');
/* Name of file holding one or more CA certificates to verify peer with*/
define('SOLR_SSL_CAINFO', 'certs/cacert.crt');
/* Name of directory holding multiple CA certificates to verify peer with */
define('SOLR_SSL_CAPATH', 'certs/');
?>
我正在使用tomcat用户名和密码来获取solr_server_username / password。和solr在UI上工作正常。我使用solr 4.6.1与php solrclient 1.0.2
<?php
// make sure browsers see this page as utf-8 encoded HTML
header('Content-Type: text/html; charset=utf-8');
$limit = 10;
$query = isset($_REQUEST['q']) ? $_REQUEST['q'] : false;
$results = false;
if ($query)
{
// The Apache Solr Client library should be on the include path
// which is usually most easily accomplished by placing in the
// same directory as this script ( . or current directory is a default
// php include path entry in the php.ini)
require_once('/usr/local/apache-tomcat-7.0.50/SolrPhpClient/Apache/Solr/Service.php');
// create a new solr service instance - host, port, and webapp
// path (all defaults in this example)
$solr = new Apache_Solr_Service('localhost', 8080, '/solr/collection1');
// if magic quotes is enabled then stripslashes will be needed
if (get_magic_quotes_gpc() == 1)
{
$query = stripslashes($query);
}
// in production code you'll always want to use a try /catch for any
// possible exceptions emitted by searching (i.e. connection
// problems or a query parsing error)
try
{
$results = $solr->search($query, 0, $limit);
}
catch (Exception $e)
{
// in production you'd probably log or email this error to an admin
// and then show a special message to the user but for this example
// we're going to show the full exception
die("<html><head><title>SEARCH EXCEPTION</title><body><pre>{$e->__toString()}</pre></body></html>");
}
}
?>

尝试上述替代代码时，遇到以下错误：

Solr的默认响应编写器是XML。
如果你想用JSON取回你的结果，你应该通过定义URL参数wt = json
来指定它。实施例
http://localhost:8983/solr/customers/select?q=customerSearchName&wt=json
确保你这样做。
