Question

我收到此错误：

Caused by: PDOException
invalid data source name
in C:\wamp64\www\quickcar\vendor\yiisoft\yii2\db\Connection.php at line 686

这是main-local.php：

return [
    'components' => [
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'quickcar',
            'username' => 'quickcar',
            'password' => 'quickcar',
            'charset' => 'utf8',
        ],

        'mailer' => [
            'class' => 'yii\swiftmailer\Mailer',
            'viewPath' => '@common/mail',
            // send all mails to a file by default. You have to set
            // 'useFileTransport' to false and configure a transport
            // for the mailer to send real emails.
            'useFileTransport' => true,
        ],
    ],
];

PDO支持多个数据库供应商，因此您需要按顺序告诉要连接的数据库。

尝试这个

'components' => [
    'db' => [
        'class' => '\yii\db\Connection',
        'dsn' => 'mysql:host=127.0.0.1;dbname=quickcar',
        'username' => 'quickcar',
        'password' => 'quickcar',
        'charset' => 'utf8',
    ],
],

如果您在mysql上使用其他端口，请这样做

'dsn' => 'mysql:host=127.0.0.1;port=3307;dbname=quickcar'

数据库异常– yii \ db \ Exception
