README
Yii2 beanstalkd web and console component which is an interface on the top of pda/pheanstalk. Thanks Paul Annesley for such a complete work.
How to use?
Installation with Composer
Just add the line under require
object in your composer.json
file.
{ "require": { ... "udokmeci/yii2-beanstalk" : "^1.0.0" } }
Then run
$> composer update
Configuration
Now add following lines in to your main
and console
configuration file under components
'beanstalk'=>[ 'class' => 'udokmeci\yii2beanstalk\Beanstalk', 'host' => '127.0.0.1', // default host 'port' => 11300, //default port 'connectTimeout' => 1, 'sleep' => false, // or int for usleep after every job ],
Now add following in to your console
configuration only.
... 'params' => $params, // add you controller with name and class name next to params. 'controllerMap' => [ 'worker' => [ 'class' => 'app\commands\WorkerController', ] ],
Producing
Now if everything is fine, you can run beandstalkd
and access to controller as
\Yii::$app->beanstalk ->putInTube('tube', $mixedData, $priority, $delay);
$mixedData
is added on v1.0 for complex usage. Anything else then string
will be send as json
format. So you can sent anything within it suppoted by json
.
Worker
For worker it also has a built in controller which runs an infinite loop and wait for new jobs. Most of the work is done in BeanstalkController
. All you have to do is to create a controller and action like below.
Controller
Create a controller under your commands
folder. Give the name anything you want to it and extend
your controller from udokmeci\yii2beanstalk\BeanstalkController
Example Controller
<?php namespace app\commands; use udokmeci\yii2beanstalk\BeanstalkController; use yii\helpers\Console; use Yii; class WorkerController extends BeanstalkController { // Those are the default values you can override const DELAY_PRIORITY = "1000"; //Default priority const DELAY_TIME = 5; //Default delay time // Used for Decaying. When DELAY_MAX reached job is deleted or delayed with const DELAY_MAX = 3; public function listenTubes(){ return ["tube"]; } /** * * @param Pheanstalk\Job $job * @return string self::BURY * self::RELEASE * self::DELAY * self::DELETE * self::NO_ACTION * self::DECAY * */ public function actionTube($job){ $sentData = $job->getData(); try { // something useful here if($everythingIsAllRight == true){ fwrite(STDOUT, Console::ansiFormat("- Everything is allright"."\n", [Console::FG_GREEN])); //Delete the job from beanstalkd return self::DELETE; } if($everythingWillBeAllRight == true){ fwrite(STDOUT, Console::ansiFormat("- Everything will be allright"."\n", [Console::FG_GREEN])); //Delay the for later try //You may prefer decay to avoid endless loop return self::DELAY; } if($IWantSomethingCustom==true){ Yii::$app->beanstalk->release($job); return self::NO_ACTION; } fwrite(STDOUT, Console::ansiFormat("- Not everything is allright!!!"."\n", [Console::FG_GREEN])); //Decay the job to try DELAY_MAX times. return self::DECAY; // if you return anything else job is burried. } catch (\Exception $e) { //If there is anything to do. fwrite(STDERR, Console::ansiFormat($e."\n", [Console::FG_RED])); // you can also bury jobs to examine later return self::BURY; } } }
Running Worker
Running console is the easiest part. Run ./yii Your controller
$> php ./yii worker
Controller will tell you, whether there are actions for correspanding tubes or beanstalk server is accessible and which tubes are listening currently. The controller handles with signals. So exit whenever you want, reserved job will not be hanged.
Any forks are welcome.
