Swoft2.x 小白学习笔记 (二) --- mysql、redis

介绍swoft中

  1、mysql、

  2、Redis

一、mysql使用:

  1、配置,在 app\bean.php文件中

   'db' => [
        'class'    => Database::class,
        'dsn'      => 'mysql:dbname=webdemo;host=localhost',
        'username' => 'root',
        'password' => 'foto_cj1',
    ],
//链接池配置
'db2.pool' => [ 'class' => Pool::class, 'database' => bean('db'), 'minActive' => 10, 'maxActive' => 20, 'maxWait' => 0, 'maxWaitTime' => 0, 'maxIdleTime' => 60, ],

  2、生成Model,一个Model对应一张表。在 /App/Model/Entity/ 文件夹下新建文件

<?php declare(strict_types=1);

namespace App\Model\Entity;

use Swoft\Db\Annotation\Mapping\Column;
use Swoft\Db\Annotation\Mapping\Entity;
use Swoft\Db\Annotation\Mapping\Id;
use Swoft\Db\Eloquent\Model;

/**
 *
 * Class Demo
 *
 * @since 2.0
 *
 * @Entity(table="demo",pool="db2.pool")  //定义Model,参数是对应的表和连接池(选填)
 */
class Demo extends Model
{
    /**
     *默认自动添加 created_at 和 updated_at,不需要时设置为false
     * @var bool
     */
    public $modelTimestamps = false;

    /**
     *
     * @Id(incrementing=false)
     * @Column(name="id")    //定义列
     *
     * @var int
     */
    private $id;

    /**
     * @Column(name="name")
     *
     * @var string|null
     */
    private $name;

    /**
     * @param int $id
     *
     * @return void
     */
    public function setId(int $id): void
    {
        $this->id = $id;
    }

    /**
     * @param string|null $name
     *
     * @return void
     */
    public function setName(?string $name): void
    {
        $this->name = $name;
    }

    /**
     * @return int
     */
    public function getId(): ?int
    {
        return $this->id;
    }

    /**
     * @return string|null
     */
    public function getName(): ?string
    {
        return $this->name;
    }
}
View Code

  3、使用(Model)    

//查询
    $user = Demo::find($)->toArray();

//修改
    $sdbuser = Demo::find($id);
    $sdbuser->setName("cjcjcjccj");
//或者
    $sdbuser->update(['name' => "dddddd"]);


  //删除
        $result = Demo::where('id', 1)->delete();

        $user = Demo::find($data["uid"]);
        $result = $user->delete();

//插入
        $count = new Demo();
        $count->setId(mt_rand(1, 100));
        $count->setName('attr');
        $result = $count->save();
        $nId = $count->getId();

//批量插入
     $insArr = [
            [
                'id'      => random_int(1, 100),
                'name'  => md5(uniqid())
            ],
            [
                'id'      => random_int(1, 100),
                'name'  => md5(uniqid())
            ]
        ];

    $result = Demo::insert($insArr);

   4、DB原生使用:https://www.swoft.org/docs/2.x/zh-CN/db/builder.html

二:Redis简单使用:

1、配置:在 app\bean.php文件中

'redis'             => [
        'class'    => RedisDb::class,
        'host'     => '127.0.0.1',
        'port'     => 6379,
        'database' => 0,
        'option'   => [
            'prefix' => 'swoft:'
        ]
    ],
    'redis.pool'     => [
        'class'   => \Swoft\Redis\Pool::class,
        'redisDb' => \bean('redis'),
        'minActive'   => 10,
        'maxActive'   => 20,
        'maxWait'     => 0,
        'maxWaitTime' => 0,
        'maxIdleTime' => 40,
    ]
View Code

2、使用

  (1)、直接使用

Redis::set($key, $setData,$time);
Redis::get($key);

      (2)、通过 @Inject注入连接池方式使用

    在/App/Http/Controller/中新建文件 

/**
 * Class RedisController
 *
 * @since 2.0
 * @Controller("redis")
 */
class RedisController
{
    /**
     * @Inject("redis.pool")   
     *
     * @var Pool
     */
    private $redis;

    /**
     * @return array
     * @RequestMapping("find")  //访问路由:  /redis/find
     * @throws \Throwable
     */
    public function find()
    {
        $us = $this->redis->get('user');
        if($us)
            $this->redis->set('user', ["name" => "gimi", "age" => "18"],120);

        return $us;
    }
}

三:Task任务:

  1、配置,在 app/bean.php文件中加入

  'httpServer' => [
        // ...
        'on'       => [
            SwooleEvent::TASK   => \bean(TaskListener::class),  // Enable task must task and finish event
            SwooleEvent::FINISH => \bean(FinishListener::class)
        ],
        /* @see HttpServer::$setting */
        'setting'  => [
            'task_worker_num'       => 12,
            'task_enable_coroutine' => true,
            'worker_num'            => 2
        ]
    ],
View Code

  2、定时任务

1、安装 composer require swoft/crontab
2、配置
 'httpServer'     => [
            // ...
            'process' => [
                'crontab' => bean(Swoft\Crontab\Process\CrontabProcess::class)
            ],
            // ...
        ],

3、定义,在/app/Task/Crontab/ 文件夹中新建文件

<?php

namespace App\Task\Crontab;

use Swoft\Crontab\Annotaion\Mapping\Cron;
use Swoft\Crontab\Annotaion\Mapping\Scheduled;

/**
 * Class DemoCronTask
 * @package App\Task\Crontab
 *
 * @Scheduled(name="demoCronTask")  //声明定时任务
 */
class DemoCronTask{

    /**
     * @Cron("*")  //每秒执行
     */
    public function secondTask(){
        var_dump("--111----",date('Y-m-d H:i:s', time()));
    }

    /**
     * @Cron("0 * * * * *") //每分钟执行
     */
    public function miunteTask(){
        var_dump("222------",date('Y-m-d H:i:s', time()));
    }
}
View Code

     3、协程、异步任务

  (1)、声明一个任务,在 /app/Task/Task/ 文件夹新建文件

<?php declare(strict_types=1);

namespace App\Task\Task;

use Swoft\Task\Annotation\Mapping\Task;
use Swoft\Task\Annotation\Mapping\TaskMapping;

/**
 * Class DemoTask
 *
 * @since 2.0
 * @Task(name="demoV2Task")  //标记类是一个任务
 */
class DemoTask
{
    /**
     * @TaskMapping(name="list")  //映射名称
     *
     * @param int    $id
     * @param string $default
     *
     * @return array
     */
    public function getList(int $id): array
    {
        var_dump("------------");

        sleep(5);

        return [
            'list'    => [1, 3, 3],
            'id'      => $id
        ];
    }

    /**
     * @param int $id
     * @return bool
     *
     * @TaskMapping(name="putLists")
     */
    public function putList(int $id) : bool
    {
        if($id > 5)
            return true;

        return false;
    }
}
View Code

       (2)、任务投递

// 协程投递
$data = Task::co('demoV2Task', 'list', [12]);

//异步投递
$data = Task::async('demoV2Task', 'list', [12]);

      (3)、异步投递如果需要关注异步任务处理结果,可以添加监听器,在文件夹 /app/Task/Listener/ 下新建文件

<?php

namespace App\Task\Listener;

use Swoft\Log\Helper\CLog;
use function context;
use Swoft\Event\Annotation\Mapping\Listener;
use Swoft\Event\EventHandlerInterface;
use Swoft\Event\EventInterface;
use Swoft\Task\TaskEvent;

/**
 * Class DemoListener
 * @package App\Task\Listener
 * @Listener(event=TaskEvent::FINISH)  //参数必须带Finsh
 */
class DemoListener implements EventHandlerInterface{

    /**
     * @param EventInterface $event
     *
     * @throws \Swoft\Exception\SwoftException
     */
    public function handle(EventInterface $event): void
    {
        // TODO: Implement handle() method.
        $fId = context()->getTaskUniqid();

//        var_dump($fId);
        CLog::info(\context()->getTaskUniqid());

        $taskData = context()->getTaskData();
//        var_dump($taskData);

        CLog::info(\context()->getTaskData());
    }
}
View Code

注意:Task中有两个地方还未清楚

      1、协程投递时是阻塞。

  2、异步监听的地方,所有监听器只有带了参数 @Listener(event=TaskEvent::FINISH) 都会执行一遍。
