laravel使用模型链接数据库

浅谈laravel模型调取数据的方法

一、首先创建模型

php artisan make:model User

二、数据连接配置config/datebase,这里可以配置多个这样的test配置

//配置1
'test1' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST1', '127.0.0.1'),
            'port' => env('DB_PORT1', '3306'),
            'database' => env('DB_DATABASE1', 'forge'),
            'username' => env('DB_USERNAME1', 'forge'),
            'password' => env('DB_PASSWORD1', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_general_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'options' => extension_loaded('pdo_mysql') ? array_filter([
                PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
            ]) : [],
        ],
//
'test2' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST2', '127.0.0.1'),
            'port' => env('DB_PORT2', '3306'),
            'database' => env('DB_DATABASE2', 'forge'),
            'username' => env('DB_USERNAME2', 'forge'),
            'password' => env('DB_PASSWORD2', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_general_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'options' => extension_loaded('pdo_mysql') ? array_filter([
                PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
            ]) : [],
        ],

三、使用model的时候调取不同数据数据可以使用静态方法 on

User::on('test1')->find(1);//链接数据库test1
User::on('test2')->find(1);//链接数据库test2
