ScrapydWeb is a web-based management tool for the Scrapyd service. It is built using the Python Flask framework and allows you to easily manage and monitor your Scrapy spider projects through a web interface.

ScrapydWeb allows you to view the status of your running spiders, view the logs of completed spiders, schedule new spider runs, and manage spider settings and configurations.

ScrapydWeb provides a simple way to manage your scraping tasks and allows you to schedule and run multiple spiders simultaneously. It also provides a user-friendly web interface that makes it easy to view the status of your spiders and monitor their progress.

You can install the package via pip by running pip install scrapydweb and then you can run the package by running scrapydweb command in your command prompt.

It will start a web server that you can access through your web browser at http://localhost:6800/ You will need to have Scrapyd running in order to use ScrapydWeb, Scrapyd is a service for running Scrapy spiders, it allows you to schedule spiders to run at regular intervals and also allows you to run spiders on remote machines.

php-spider is a PHP library for web crawling and scraping. It allows developers to easily navigate and extract data from websites by simulating a web browser's behavior.

supports two traversal algorithms: breadth-first and depth-first
supports crawl depth limiting, queue size limiting and max downloads limiting
supports adding custom URI discovery logic, based on XPath, CSS selectors, or plain old PHP
comes with a useful set of URI filters, such as Domain limiting
supports custom URI filters, both prefetch (URI) and postfetch (Resource content)
supports custom request handling logic
supports Basic, Digest and NTLM HTTP authentication. See example.
comes with a useful set of persistence handlers (memory, file)
supports custom persistence handlers
collects statistics about the crawl for reporting
dispatches useful events, allowing developers to add even more custom behavior
supports a politeness policy

This Spider does not support Javascript.

Example Use

```php use Example\StatsHandler; use VDB\Spider\Discoverer\XPathExpressionDiscoverer; use Symfony\Contracts\EventDispatcher\Event; use VDB\Spider\Event\SpiderEvents; use VDB\Spider\Spider; require_once('example_complex_bootstrap.php'); // Create Spider $spider = new Spider('http://dmoztools.net'); // Add a URI discoverer. Without it, the spider does nothing. In this case, we want tags from a certain

$spider->getDiscovererSet()->set(new XPathExpressionDiscoverer("//div[@id='catalogs']//a")); // Set some sane options for this example. In this case, we only get the first 10 items from the start page. $spider->getDiscovererSet()->maxDepth = 1; $spider->getQueueManager()->maxQueueSize = 10; // Let's add something to enable us to stop the script $spider->getDispatcher()->addListener( SpiderEvents::SPIDER_CRAWL_USER_STOPPED, function (Event $event) { echo "\nCrawl aborted by user.\n"; exit(); } ); // Add a listener to collect stats to the Spider and the QueueMananger. // There are more components that dispatch events you can use. $statsHandler = new StatsHandler(); $spider->getQueueManager()->getDispatcher()->addSubscriber($statsHandler); $spider->getDispatcher()->addSubscriber($statsHandler); // Execute crawl $spider->crawl(); // Build a report echo "\n ENQUEUED: " . count($statsHandler->getQueued()); echo "\n SKIPPED: " . count($statsHandler->getFiltered()); echo "\n FAILED: " . count($statsHandler->getFailed()); echo "\n PERSISTED: " . count($statsHandler->getPersisted()); // Finally we could do some processing on the downloaded resources // In this example, we will echo the title of all resources echo "\n\nDOWNLOADED RESOURCES: "; foreach ($spider->getDownloader()->getPersistenceHandler() as $resource) { echo "\n - " . $resource->getCrawler()->filterXpath('//title')->text(); } ```
