Fatal error: Uncaught exception 'Everyman\Neo4j\Exception' with message 'Unable to retrieve server info [401]:

I just installed neo4j server in Windows and am trying to connect with php. I have xampp running, installed neo4jphp with composer, and then tried to check the connection using the following script:

<?php
    require('vendor/autoload.php');


    $client = new Everyman\Neo4j\Client('localhost', 7474);
    print_r($client->getServerInfo());
?>

Now, instead of showing server status, a fatal error occured like this:

Fatal error: Uncaught exception 'Everyman\Neo4j\Exception' with message 'Unable to retrieve server info [401]: Headers: Array ( [Date] => Wed, 27 May 2015 10:54:01 GMT [Content-Type] => application/json; charset=UTF-8 [WWW-Authenticate] => None [Content-Length] => 144 [Server] => Jetty(9.2.z-SNAPSHOT) ) Body: Array ( [errors] => Array ( [0] => Array ( [message] => No authorization header supplied.

How to solve this? Any help will be appreciated. Thanks in advance.

Solution

It will work. You just need to define the authorization credentials, for example like this:

<?php
   require('vendor/autoload.php');

   $client = new Everyman\Neo4j\Client(
            (new Everyman\Neo4j\Transport\Curl('localhost',7474))
                ->setAuth('neo4j','neo4j')
   );

   print_r($client->getServerInfo());

Adjust the user/password accordingly('neo4j'/'neo4j' are default ones).

Another solution is to disable the requirement for authorization when accessing Neo4j. This can be done by editing Neo4j config file:

conf/neo4j-server.properties

and setting to false the following flag:

dbms.security.auth_enabled=false

Of course you need to remember about restarting the server afterwards.
