THIS PACKAGE IS NOT MAINTAINED ANYMORE
Check all links in a Laravel app
This package provides a command that can check all links on your laravel app. By default, it will log all links that do not return a status code in the 200- or 300-range. There's also an option to mail broken links.
If you like this package, take a look at the other ones we have made.
Install
You can install the package via composer:
composer require spatie/laravel-link-checker
Next, you must install the service provider:
// config/app.php
'providers' => [
...
Spatie\LinkChecker\LinkCheckerServiceProvider::class,
];
The service provider will automatically be registered.
You can optionally publish the config-file with:
php artisan vendor:publish --provider="Spatie\LinkChecker\LinkCheckerServiceProvider" --tag="config"
This is the contents of the published config file:
return [
/*
* The base url of your app. Leave this empty to use
* the url configured in config/app.php
*/
'url' => '',
/*
* The profile determines which links need to be checked.
*/
'default_profile' => Spatie\LinkChecker\CheckAllLinks::class,
/*
* The reporter determines what needs to be done when the
* the crawler has visited a link.
*/
'default_reporter' => Spatie\LinkChecker\Reporters\LogBrokenLinks::class,
/*
* To speed up the checking process we'll fire off requests concurrently.
* Here you can change the amount of concurrent requests.
*/
'concurrency' => 10
/*
* Here you can specify configuration regarding the used reporters
*/
'reporters' => [
'mail' => [
/*
* The `from` address to be used by the mail reporter.
*/
'from_address' => '',
/*
* The `to` address to be used by the mail reporter.
*/
'to_address' => '',
/*
* The subject line to be used by the mail reporter.
*/
'subject' => '',
],
/*
* If you wish to exclude status codes from the reporters,
* you can select the status codes that you wish to
* exclude in the array below like: [200, 302]
*/
'exclude_status_codes' => [],
],
];
Usage
You can start checking all links by issuing this command:
php artisan link-checker:run
Want to run the crawler on a different url? No problem!
php artisan link-checker:run --url=https://laravel.com
Schedule the command
To frequently check all links you can schedule the command:
// app/console/Kernel.php
protected function schedule(Schedule $schedule)
{
...
$schedule->command('link-checker:run')->sundays()->daily();
}
Mail broken links
By default the package will log all broken links. If you want to have them mailed instead, just specify
Spatie\LinkChecker\Reporters\MailBrokenLinks in the default_reporter option in the config file.
Creating your own crawl profile
A crawlprofile determines which links need to be crawled. By default Spatie\LinkChecker\CheckAllLinks is used,
which will check all links it finds. This behaviour can be customized by specifying a class in the default_profile-option in the config file.
The class must extend the abstract class Spatie\Crawler\CrawlProfile:
abstract class CrawlProfile
{
/**
* Determine if the given url should be crawled.
*
* @param \Psr\Http\Message\UriInterface $url
*
* @return bool
*/
abstract public function shouldCrawl(UriInterface $url): bool;
}
Creating your own reporter
A reporter determines what should be done when a link is crawled and when the crawling process is finished.
This package provides two reporters: Spatie\LinkChecker\Reporters\LogBrokenLinks and Spatie\LinkChecker\Reporters\MailBrokenLinks.
You can create your own behaviour by making a class extend the abstract class Spatie\Crawler\CrawlObserver:
abstract class CrawlObserver
{
/**
* Called when the crawler will crawl the url.
*
* @param \Psr\Http\Message\UriInterface $url
*/
public function willCrawl(UriInterface $url)
{
}
/**
* Called when the crawler has crawled the given url successfully.
*
* @param \Psr\Http\Message\UriInterface $url
* @param \Psr\Http\Message\ResponseInterface $response
* @param \Psr\Http\Message\UriInterface|null $foundOnUrl
*/
abstract public function crawled(
UriInterface $url,
ResponseInterface $response,
?UriInterface $foundOnUrl = null
);
/**
* Called when the crawler had a problem crawling the given url.
*
* @param \Psr\Http\Message\UriInterface $url
* @param \GuzzleHttp\Exception\RequestException $requestException
* @param \Psr\Http\Message\UriInterface|null $foundOnUrl
*/
abstract public function crawlFailed(
UriInterface $url,
RequestException $requestException,
?UriInterface $foundOnUrl = null
);
/**
* Called when the crawl has ended.
*/
public function finishedCrawling()
{
}
}
To make it easier to create a reporter, you can extend Spatie\LinkChecker\Reporters\BaseReporter which
provides many useful methods.
