我的 Laravel 項(xiàng)目有問(wèn)題。我?guī)讉€(gè)小時(shí)前開(kāi)始使用它，但遇到了 SQL 錯(cuò)誤：SQLSTATE[HY000] [2002] 連接被拒絕我已經(jīng)搜索了幾個(gè)小時(shí)，只發(fā)現(xiàn)密碼錯(cuò)誤或端口錯(cuò)誤，但我檢查了一下，這對(duì)我來(lái)說(shuō)沒(méi)問(wèn)題。這是 .env 文件：DB_CONNECTION=mysqlDB_HOST=localhostDB_PORT=3302DB_DATABASE=test_techniqueDB_USERNAME=rootDB_PASSWORD=這是 .env.example 文件：DB_CONNECTION=mysqlDB_HOST=localhostDB_PORT=3302DB_DATABASE=test_techniqueDB_USERNAME=rootDB_PASSWORD=這是database.php：'mysql' => [        'driver' => 'mysql',        'url' => env('DATABASE_URL'),        'host' => env('DB_HOST', 'localhost'),        'port' => env('DB_PORT', '3302'),        'database' => env('DB_DATABASE', 'test_technique'),        'username' => env('DB_USERNAME', 'root'),        'password' => env('DB_PASSWORD', ''),        'unix_socket' => env('DB_SOCKET', ''),        'charset' => 'utf8mb4',        'collation' => 'utf8mb4_unicode_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'),        ]) : [],    ],并檢查 mysql 的端口：Test for TCPYour port 3302 is used by a processus with PID = 2292The processus of PID 2292 is 'mysqld.exe' Session: ServicesThe service of PID 2292 for 'mysqld.exe' is 'N/A'N/A means that there are no service related to PID 2292Processus 'mysqld.exe' is launched by service 'wampmysqld64' with PID 5048Test for TCPv6Your port 3302 is used by a processus with PID = 2292The processus of PID 2292 is 'mysqld.exe' Session: ServicesThe service of PID 2292 for 'mysqld.exe' is 'N/A'N/A means that there are no service related to PID 2292Processus 'mysqld.exe' is launched by service 'wampmysqld64' with PID 5048我從未更改過(guò) mysql 中的用戶名和密碼，所以我不知道為什么會(huì)出現(xiàn)此錯(cuò)誤PS：在另一個(gè)站點(diǎn)中，當(dāng)我像這樣使用 PDO 時(shí)，它可以工作：new PDO("mysql:host=localhost:3302;dbname=test_technique;charset=utf8", "root", "",array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));
