Crawler Client PHP

PHP Client for 68publishers/crawler

Installation

$ composer require 68publishers/crawler-client-php

Client initialization

The client instance is simply created by calling the static method create().

use SixtyEightPublishers\CrawlerClient\CrawlerClient;

$client = CrawlerClient::create('<full url to your crawler instance>');

The Guzzle library is used to communicate with the Crawler API. If you want to pass some custom options to the configuration for Guzzle, use the second optional parameter.

use SixtyEightPublishers\CrawlerClient\CrawlerClient;

$client = CrawlerClient::create('<full url to your crawler instance>', [
    'timeout' => 0,
]);

Requests to the Crawler API must always be authenticated, so we must provide credentials.

use SixtyEightPublishers\CrawlerClient\CrawlerClient;
use SixtyEightPublishers\CrawlerClient\Authentication\Credentials;

$client = CrawlerClient::create('<full url to your crawler instance>');

$client = $client->withAuthentication(new Credentials('<username>', '<password>'));

It should be pointed out that the client is immutable - calling the with* methods always returns a new instance. This is all that is needed for the client to work properly. You can read about other options on the Advanced options page.

Working with scenarios

Scenarios are handled by ScenarioController.

use SixtyEightPublishers\CrawlerClient\Controller\Scenario\ScenariosController;

$controller = $client->getController(ScenariosController::class);

List scenarios

/**
 * @param int $page
 * @param int $limit
 * @param array<string, string|array<string>> $filter
 * 
 * @returns \SixtyEightPublishers\CrawlerClient\Controller\Scenario\ScenarioListingResponse
 * 
 * @throws \SixtyEightPublishers\CrawlerClient\Exception\BadRequestException
 */

$response = $controller->listScenarios(1, 10);

$filteredResponse = $controller->listScenarios(1, 10, [
    'name' => 'Test',
    'status' => 'failed',
])

Get scenario

/**
 * @param string $scenarioId
 * 
 * @returns \SixtyEightPublishers\CrawlerClient\Controller\Scenario\ScenarioResponse
 * 
 * @throws \SixtyEightPublishers\CrawlerClient\Exception\BadRequestException
 * @throws \SixtyEightPublishers\CrawlerClient\Exception\NotFoundException
 */

$response = $controller->getScenario('<id>');

Run scenario

/**
 * @param \SixtyEightPublishers\CrawlerClient\Controller\Scenario\RequestBody\ScenarioRequestBody $requestBody
 * 
 * @returns \SixtyEightPublishers\CrawlerClient\Controller\Scenario\ScenarioResponse
 * 
 * @throws \SixtyEightPublishers\CrawlerClient\Exception\BadRequestException
 */

As a scenario config we can pass a normal array or use prepared value objects. Both options are valid.

 use SixtyEightPublishers\CrawlerClient\Controller\Scenario\RequestBody\ScenarioRequestBody;

$requestBody = new ScenarioRequestBody(
    name: 'My scenario',
    flags: ['my_flag' => 'my_flag_value'],
    config: [
        'scenes' => [ /* ... */ ],
        'options' => [ /* ... */ ],
        'entrypoint' => [ /* ... */ ],
    ],
)

$response = $controller->runScenario($requestBody);

 use SixtyEightPublishers\CrawlerClient\Controller\Scenario\RequestBody\ScenarioRequestBody;
 use SixtyEightPublishers\CrawlerClient\Controller\Scenario\ValueObject\ScenarioConfig;
 use SixtyEightPublishers\CrawlerClient\Controller\Scenario\ValueObject\Entrypoint;
 use SixtyEightPublishers\CrawlerClient\Controller\Scenario\ValueObject\Action;

$requestBody = new ScenarioRequestBody(
    name: 'My scenario',
    flags: ['my_flag' => 'my_flag_value'],
    config: (new ScenarioConfig(new Entrypoint('<url>', 'default')))
        ->withOptions(/* ... */)
        ->withScene('default', [
            new Action('...', [ /* ... */ ])
            new Action('...', [ /* ... */ ])
        ]),
)

$response = $controller->runScenario($requestBody);

Validate scenario

/**

 * 
 * @returns \SixtyEightPublishers\CrawlerClient\Controller\Scenario\ValidateScenarioResponse

            new Action('...', [ /* ... */ ])
        ]),
)

$response = $controller->validateScenario($requestBody);

Abort scenario

/**

 * 
 * @returns \SixtyEightPublishers\CrawlerClient\Controller\Common\NoContentResponse
 * 
 * @throws \SixtyEightPublishers\CrawlerClient\Exception\BadRequestException
 * @throws \SixtyEightPublishers\CrawlerClient\Exception\NotFoundException

Working with scenario schedulers

Scenario schedulers are handled by ScenarioSchedulersController.

use SixtyEightPublishers\CrawlerClient\Controller\ScenarioScheduler\ScenarioSchedulersController;

$controller = $client->getController(ScenarioSchedulersController::class);

List scenario schedulers

/**
 * @param int $page
 * @param int $limit
 * @param array<string, string|array<string>> $filter
 *

 * @throws \SixtyEightPublishers\CrawlerClient\Exception\BadRequestException
 */

$response = $controller->listScenarioSchedulers(1, 10);

$filteredResponse = $controller->listScenarioSchedulers(1, 10, [
    'name' => 'Test',
    'userId' => '<id>',
])

Get scenario scheduler

/**
 * @param string $scenarioSchedulerId
 * 
 * @returns \SixtyEightPublishers\CrawlerClient\Controller\ScenarioScheduler\ScenarioSchedulerResponse
 * 
 * @throws \SixtyEightPublishers\CrawlerClient\Exception\BadRequestException
 * @throws \SixtyEightPublishers\CrawlerClient\Exception\NotFoundException
 */

$response = $controller->getScenarioScheduler('<id>');
$etag = $response->getEtag(); # you need Etag for update
