easyswoole orm安装及多数据的连接操作

一：安装 Mysqli
composer require easyswoole/mysqli
二：安装ORM
composer require easyswoole/orm
三：dev.php 中填写配置信息，可以填写多个数据库连接，还有redis，七牛云等一些配置信息，这里主要写连接多个数据的

return [
    'SERVER_NAME' => "EasySwoole",
    'MAIN_SERVER' => [
        'LISTEN_ADDRESS' => '0.0.0.0',
        'PORT' => 9502,
        'SERVER_TYPE' => EASYSWOOLE_WEB_SERVER, //可选为 EASYSWOOLE_SERVER  EASYSWOOLE_WEB_SERVER EASYSWOOLE_WEB_SOCKET_SERVER,EASYSWOOLE_REDIS_SERVER
        'SOCK_TYPE' => SWOOLE_TCP,
        'RUN_MODEL' => SWOOLE_PROCESS,
        'SETTING' => [
            'worker_num' => 8,
            'reload_async' => true,
            'max_wait_time'=>3
        ],
        'TASK'=>[
            'workerNum'=>4,
            'maxRunningNum'=>128,
            'timeout'=>15
        ]
    ],
    'TEMP_DIR' => null,
    'LOG_DIR' => null,

    /*################ MYSQL CONFIG ##################*/
    'MYSQL' => [
        //数据库配置
        'host'                 => '127.0.0.1',//数据库连接ip
        'user'                 => '',//数据库用户名
        'password'             => '',//数据库密码
        'database'             => '',//数据库
        'port'                 => '3306',//端口
        'timeout'              => '30',//超时时间
        'connect_timeout'      => '5',//连接超时时间
        'charset'              => 'utf8mb4',//字符编码
        'strict_type'          => false, //开启严格模式，返回的字段将自动转为数字类型
        'fetch_mode'           => false,//开启fetch模式, 可与pdo一样使用fetch/fetchAll逐行或获取全部结果集(4.0版本以上)
        'alias'                => '',//子查询别名
        'isSubQuery'           => false,//是否为子查询
        'max_reconnect_times ' => '3',//最大重连次数
    ],

    /*################ Company MYSQL CONFIG ##################*/
    'MYSQL_CASE' => [
        //数据库配置
        'host'                 => '',//数据库连接ip
        'user'                 => '',//数据库用户名
        'password'             => '',//数据库密码
        'database'             => '',//数据库
        'port'                 => '3306',//端口
        'timeout'              => '30',//超时时间
        'connect_timeout'      => '5',//连接超时时间
        'charset'              => 'utf8mb4',//字符编码
        'strict_type'          => false, //开启严格模式，返回的字段将自动转为数字类型
        'fetch_mode'           => false,//开启fetch模式, 可与pdo一样使用fetch/fetchAll逐行或获取全部结果集(4.0版本以上)
        'alias'                => '',//子查询别名
        'isSubQuery'           => false,//是否为子查询
        'max_reconnect_times ' => '3',//最大重连次数
    ],

];

四：EasyswooleEvent.php 文件中配置数据库连接，预连接

namespace EasySwoole\EasySwoole;
use EasySwoole\EasySwoole\Bridge\Exception;
use EasySwoole\EasySwoole\Swoole\EventRegister;
use EasySwoole\EasySwoole\AbstractInterface\Event;
use EasySwoole\Http\Request;
use EasySwoole\Http\Response;
use EasySwoole\ORM\DbManager;
use EasySwoole\ORM\Db\Connection;
use EasySwoole\ORM\Db\Config;
use EasySwoole\EasySwoole\Config as GlobalConfig;

class EasySwooleEvent implements Event
{

    public static function initialize()
    {
        // TODO: Implement initialize() method.
        date_default_timezone_set('Asia/Shanghai');
    }

    public static function mainServerCreate(EventRegister $register)
    {
        // TODO: Implement mainServerCreate() method.
        //连接数据库配置
        $config  = new Config(GlobalConfig::getInstance()->getConf("MYSQL"));
        $configs = new Config(GlobalConfig::getInstance()->getConf("MYSQL_CASE"));
        try{
            DbManager::getInstance()->addConnection(new Connection($config),'mysql');
            DbManager::getInstance()->addConnection(new Connection($configs),'mysql_case');
        }catch (Exception $e){

        }
    }

    public static function onRequest(Request $request, Response $response): bool
    {
        // TODO: Implement onRequest() method.
        return true;
    }

    public static function afterRequest(Request $request, Response $response): void
    {
        // TODO: Implement afterAction() method.
    }
}

五：在Model中的处理

namespace App\Models;
use EasySwoole\ORM\AbstractModel;
use EasySwoole\ORM\Utility\Schema\Table;

class UserModel extends AbstractModel
{
    //选择连接的数据库
    protected $connectionName = 'mysql';
    //选择表
    protected $tableName = 'k_user';


}

到此为止多数据库的连接就完成了。
