gdapi-php

A PHP client for Go Daddy® REST APIs.

Requirements

• PHP 5.3 or greater
• libcurl PHP extension with SSL support
• An account in a compatible service, such as Cloud Servers™
• Your API Access and Secret key pair

Getting Started

If you haven't already tried it, open up the base URL of the API you want to use in a browser. Enter your Access Key as the username and your Secret Key as the password. This interface will allow you to get familiar with what Resource types are available in the API and what operations and actions you can perform on them.

Connecting

<?php
require_once('gdapi-php/init.php');
$url        = 'https://api.cloud.secureserver.net/v1/schemas';
$access_key = 'your-access-key';
$secret_key = 'your-secret-key';
    
$client = new \GDAPI\Client($url, $access_key, $secret_key);
?>

Problems connecting

Consult the SSL Problems section if you get an error when creating the client that says something like this:

SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Finding Resources

Each resource type in the API is available as a member of the Client.

Listing all resources in a collection

<?php
$machines = $client->virtualmachine->query();
echo "There are " . count($machines) . " machines:\n";
foreach ( $machines as $machine )
{
  echo $machine->getName() . "\n";
}
?>

Filtering

Filters allow you to search a collection for resources matching a set of conditions.

<?php
$http_balancers = $client->loadbalancers->query(array(
  'publicStartPort' => 80,
));

$privileged_portforwards = $client->portforwards->query(array(
  'publicStartPort' => array('modifier' => 'lt', 'value' => 1024)
));

$active_machines = $client->virtualmachine->query(array(
  'removed' => array('modifier' => 'null')
));
?>

Getting a single Resource by ID

If you know the ID of the resource you are looking for already, you can also get it directly.

<?php
$machine = $client->virtualmachine->getById('your-machine-id');
?>

Working with Resources

Accessing attributes

Resources have a getter method for each attribute, as "get"+{attribute name}. Attributes that can be changed also have a "set"+{attribute name} method. The first character of the attribute name may be capitalized for readability, but the rest of the name must match the API.

<?php
$machine = $client->virtualmachine->getById('your-machine-id');

$privateIp = $machine->getPrivateIpv4Address(); // e.g. '10.1.1.3'
$size = $machine->getRamSizeMb(); // e.g. 1024
?>

Making changes

<?php
$machine = $client->virtualmachine->getById('your-machine-id');
$machine->setName('bigger machine');
$machine->setOffering('2gb-4cpu');

// Save the changes
$result = $machine->save();
?>

Creating new resources

<?php
$network = $client->network->create(array(
  'name'     => 'My Network',
  'domain'   => 'mynetwork.local',
  'ipv4Cidr' => '192.168.0.0/24'
));
?>

Removing resources

With an instance of the resource:

<?php
$machine = $client->virtualmachine->getById('your-machine-id');
$result = $machine->remove();
?>

Or statically:

<?php
$result = $client->virtualmachine->remove('your-machine-id');
?>

Executing Actions

Actions are used to perform operations that go beyond simple create/read/update/delete. Resources have a "do"+{action name} method for each action. The first character of the action name may be capitalized for readability, but the rest of the name must match the API.

<?php
$machine = $client->virtualmachine->getById('your-machine-id');
$result = $machine->doRestart();
?>

Following Links

Response collections and resources generally have a "links" attribute containing URLs to related resources and collections. For example a virtual machine belongs to a network and has one or more volumes. Resources have a "fetch"+{link name} method for each link. Invoking this will return the linked resource

<?php
$machine = $client->virtualmachine->getById('your-machine-id');
$network = $machine->fetchNetwork(); // Network resource
$volumes = $machine->fetchVolumes(); // Collection of Volume resources
?>

Handling Errors

By default, any error response will be thrown as an exception. The most general type of exception is \GDAPI\APIException, but several more specific types are defined in class/APIException.php.

<?php
try
{
  $machine = $client->virtualmachine->getById('your-machine-id');
  echo "I found it";
}
catch ( \GDAPI\NotFoundException $e )
{
  echo "I couldn't find that machine";
}
catch ( \GDAPI\APIException $e )
{
  echo "Something else went wrong";
}
?>

If you prefer to not use exceptions, the client has an option to disable them. When an error occurs, the response will be an instance of \GDAPI\Error.

<?php
$machine = $client->virtualmachine->getById('your-machine-id');
if ( $machine instanceof \GDAPI\Error )
{
  if ( $machine->getStatus() == 404 )
  {
    echo "I couldn't find that machine";
  }
  else
  {
    echo "Something else went wrong: " . print_r($machine,true);
  }
}
else
{
  echo "I found it";
}
?>

Advanced Options

Mapping response objects to your own classes

By default all response objects are an instance of \GDAPI\Resource, \GDAPI\Collection, or \GDAPI\Error. In many cases it is useful to map responses to your own classes and add your own behavior to them.

<?php

class MyVM extends \GDAPI\Resource
{
  function getFQDN()
  {
    $network = $this->fetchNetwork();
    return $this->getName() . "." . $network->getDomain();
  }
}

class MyLoadBalancer extends \GDAPI\Resource
{
  function getFQDN()
  {
    $network = $this->fetchNetwork();
    return $this->getName() . "." . $network->getDomain();
  }
}

$classmap = array(
  'virtualmachine' => 'MyVM',
  'loadbalancer'   => 'MyLoadBalancer'
);

$options = array(
  'classmap' => $classmap
);

$client = new \GDAPI\Client($url, $access_key, $secret_key, $options);

$machines = $client->virtualmachine->query();
echo "There are " . count($machines) . " machines:\n";
foreach ( $machines as $machine )
{
  echo $machine->getFQDN() ."\n";
}
?>

SSL Problems

Some installations of libcurl do not come with certificates for any Certificate Authorities (CA). This client always verifies the certificate by default, but having no CA certificates means it won't be able to verify any SSL certificate. To fix this problem, you need a list of CA certificates to trust. Curl provides a copy that contains the same CA certs as Mozilla browsers: cacert.pem.

If you have permission to edit your php.ini, you can fix this globally for anything that uses the libcurl extension:

Add a line like this to your php.ini, then restart your web server, if applicable:

curl.cainfo = /path/to/cacert.pem

If you don't have permission, or don't want to make a global change, you can configure just the GDAPI client to use the file:

<?php
$options = array(
  'ca_cert' => '/path/to/cacert.pem'
);

$client = new \GDAPI\Client($url, $access_key, $secret_key, $options);
?>
