Cant connect to PowerdDNS - php fatal error

[tkald]

Detailed description

Seems like I can't connect to PDNS api - even though everything seems correct.
Changed also api port to 8081 in /src/Powerdns.php file.

php add.php

PHP Fatal error:  Uncaught Error: Wrong parameters for Exonet\Powerdns\Exceptions\PowerdnsException([string $message [, long $code [, Throwable $previous = NULL]]]) in /root/www/vendor/exonet/powerdns-php/src/Connector.php:159

cat add.php

<?php

require __DIR__.'/CliLogger.php';
use Exonet\Powerdns\Powerdns;
use Exonet\Powerdns\RecordType;

// Initialize the Powerdns client.
$powerdns = new Powerdns('192.168.40.175', 'redacted_key');
// Create a new zone.
$zone = $powerdns->createZone(
    'example.com',
    ['ns1.example.com.', 'ns2.example.']
);

// Add two DNS records to the zone.
$zone->create([
    ['type' => RecordType::A, 'content' => '127.0.0.1', 'ttl' => 60, 'name' => '@'],
    ['type' => RecordType::A, 'content' => '127.0.0.1', 'ttl' => 60, 'name' => 'www'],

Your environment

• Ubuntu 18.04

• PHP 7.2.19-0ubuntu0.18.04.1 (cli)

• powerdns-php v 1.0

• pdns-server v 4.1.10-1pdns.xenial

Hi @tkald,

Can you add $powerdns->setLogger(new CliLogger()); to your script, just below $powerdns = new Powerdns('192.168.40.175', 'redacted_key');? Apparently an error is returned from PowerDNS, but without content (or at least not an error object). By 'activating' the CLI logger some more info is displayed for each step and it should at least show the HTTP code as returned by PowerDNS.

Thank you, @trizz !

Added logger line to php and got 400 error:

Tried same payload/headers directly with curl - no problem creating content.

Unfortunatly, I can not reproduce this specific error. I've used the exact same code as you've posted above, but all without errors. I've pushed a new branch with a possible fix for the 'Uncaught Error' and a fix for the wrong PTR field. Can you try that branch and see if a more clear error is returned?

According to the API documentation it is possible that you're code is not sending the data in UTF8, but I can't validate that.

Changed also api port to 8081 in /src/Powerdns.php file.

If you need to define a different port, it can be done when constructing the client, there is no need to change the package source for that:

$powerdns = new Powerdns('192.168.40.175', 'redacted_key', 8081);

thaks @trizz !

Switched to new branch.
I added var_dump($response) in parseRespone function and got "Bad Request" response from PDNS:

Did some network packet capture comparisons with curl post request and noticed that with curl header Content-Type => application/x-www-form-urlencoded is added.
So I also added Content-Type to headers application sends in Connector.php:

private function getDefaultHeaders() : array
    {
        return [
            'X-API-Key' => $this->powerdns->getConfig()['apiKey'],
            'Accept' => 'application/json',
            'User-Agent' => 'exonet-powerdns-php/'.Powerdns::CLIENT_VERSION,
            'Content-Type' => 'application/json',
        ];
    }

And voila, example.com domain got created to my PDSN.
Works with application/x-www-form-urlencoded Content-Type also.

I've updated my branch. Can you validate that the client is working for you as expected?

[tkald]

Yes, all good. Thank you @trizz !

@tkald A new version is published!
