我有一堂课,扩展了雄辩的胶囊管理器:
class Database extends \Illuminate\Database\Capsule\Manager
在其中,我要在构造函数中添加一个连接:
public function __construct()
{
parent::__construct();
try {
$this->addConnection([
'driver' => 'mysql',
'host' => $server,
'database' => $database,
'username' => $username,
'password' => $password,
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
]);
$this->setAsGlobal();
$this->bootEloquent();
} catch (\Exception $ex) {
exit("Can't connect to database");
}
}
这里的问题是从不调用catch,如果任何数据库连接信息为假,我将得到一个Fatal error: Uncaught PDOException
,而不是我想要获得的出口。
我认为问题是由于我有我自己的类,该类扩展了胶囊管理器,但是我如何使用雄辩的语言来捕获我自己类中的连接错误?
编辑:回溯-
致命错误:未捕获PDOException:PDO :: __ construct():php_network_getaddresses:getaddrinfo失败:在/var/www/vendor/illuminate/database/Connectors/Connector.php中未知的名称或服务:70堆栈跟踪:#0 /var/www/vendor/illuminate/database/Connectors/Connector.php(70):PDO-> __ construct('mysql:host = mari ...','root','root',Array)#1 / var /www/vendor/illuminate/database/Connectors/Connector.php(46):Illuminate \ Database \ Connectors \ Connector-> createPdoConnection('mysql:host = mari ...','root','root',Array) #2 /var/www/vendor/illuminate/database/Connectors/MySqlConnector.php(24):Illuminate \ Database \ Connectors \ Connector-> createConnection('mysql:host = mari ...',Array,Array)#3 /var/www/vendor/illuminate/database/Connectors/ConnectionFactory.php(182):Illuminate\Database\Connectors\MySqlConnector->connect(Array)#4 [内部功能]:Illuminate \ Database \ Connectors \ ConnectionFactory-> Illuminate \ Database \ Connectors {closure}()#5 /var/www/vendor/illuminate/database/Connection.php(918 ):第664行的/var/www/vendor/illuminate/database/Connection.php中的call_user_func(Object(Closure))#6 / va
使类看起来像这样,并扩展select
,update
,insert
函数:
class Database extends \Illuminate\Database\Capsule\Manager
{
public function __construct()
{
}
public static function select(string $query, array $params = [])
{
}
public static function insert(string $query, array $params = [])
{
}
public static function update(string $query, array $params = [])
{
return parent::update($query, $params);
}
}
然后编写例如:
new Database;
Database::update('XXX', []);
