php - Solr comands not returning json output -
i going through php documentation solr , wanted try out basic example. expected output isn't received , blank page returned when try following code existing project.
<?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()); ?> the bootstrap.php goes this:
/* domain name of solr server */ define('solr_server_hostname', 'localhost'); /* whether or not run in secure mode */ define('solr_secure', false); /* http port 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 */ /* maximum time in seconds allowed http data transfer operation.default value 30 seconds */ define('solr_server_timeout', 10); /* file name pem-formatted private key + private certificate (concatenated in order) */ define('solr_ssl_cert', 'certs/combo.pem'); /* file name pem-formatted private certificate */ define('solr_ssl_cert_only', 'certs/solr.crt'); /* file name pem-formatted private key */ define('solr_ssl_key', 'certs/solr.key'); /* password pem-formatted private key file */ define('solr_ssl_keypassword', 'strongandsecurepassword'); /* name of file holding 1 or more ca certificates verify peer with*/ define('solr_ssl_cainfo', 'certs/cacert.crt'); /* name of directory holding multiple ca certificates verify peer */ define('solr_ssl_capath', 'certs/'); ?> i'm using tomcat username , password solr_server_username/password. , solr working fine otherwise on ui. using solr 4.6.1 php solrclient 1.0.2

2 {main}
solr's default response writer xml.
if want results in json, should specify defining url parameter wt=json
example
http://localhost:8983/solr/customers/select?q=customersearchname&wt=json make sure so.
