按照以下说明进行操作
步骤 1:打开 config/app.php
,找到 Datasources
数组,并像下面一样添加 远程数据库
配置 -
'Datasources' => [
'default' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => 'localhost',
'port' => '3306',
'username' => 'YOUR_DB_USER',
'password' => 'YOUR_DB_PASS',
'database' => 'YOUR_DB_NAME',
'encoding' => 'utf8',
'timezone' => 'UTC',
'flags' => [],
'cacheMetadata' => false,
'log' => false,
'quoteIdentifiers' => false,
'url' => env('DATABASE_URL', null),
],
'remote_db_1' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => '192.168.1.47',
'port' => '3306',
'username' => 'REMOTE_DB_USER',
'password' => 'REMOTE_DB_PASS',
'database' => 'REMOTE_DB_NAME',
'encoding' => 'utf8',
'timezone' => 'UTC',
'flags' => [],
'cacheMetadata' => false,
'log' => false,
'quoteIdentifiers' => false,
'url' => env('DATABASE_URL', null),
],
'remote_db_2' => [
'className' => 'Cake\Database\Connection',
'driver' => 'Cake\Database\Driver\Mysql',
'persistent' => false,
'host' => '192.168.1.47',
'port' => '3306',
'username' => 'REMOTE_DB_USER',
'password' => 'REMOTE_DB_PASS',
'database' => 'REMOTE_DB_NAME',
'encoding' => 'utf8',
'timezone' => 'UTC',
'flags' => [],
'cacheMetadata' => false,
'log' => false,
'quoteIdentifiers' => false,
'url' => env('DATABASE_URL', null),
],
步骤 2:现在您可以像这样在控制器中访问 远程数据库
-
use Cake\Datasource\ConnectionManager;
use \PDO;
class YourController extends AppController{
public function getRemoteData(){
$conn1 = ConnectionManager::get('remote_db_1');
$conn2 = ConnectionManager::get('remote_db_2');
}
}
注意:现在您可以使用PDO
方法来进行插入、检索、更新操作。
示例:
class YourController extends AppController{
public function getRemoteData(){
$conn1 = ConnectionManager::get('remote_db_1');
$sql = "SELECT * FROM users";
$query = $conn1->prepare($sql);
$query->execute();
$result = $query->fetchAll();
}
}
