How to connect Postgresql database in Slim framework with PDO? - php

Question

I work with MYSQL database in slim framework. Its perfectly worked.
But going to connect Postgresql, It not connected as well.
Here is the sample Coding: (settings.php)
declare(strict_types=1);
use App\Application\Settings\Settings;
use App\Application\Settings\SettingsInterface;
use DI\ContainerBuilder;
use Monolog\Logger;
return function (ContainerBuilder $containerBuilder) {
$containerBuilder->addDefinitions([
SettingsInterface::class => function () {
return new Settings([
'displayErrorDetails' => true, // Should be set to false in production
'logError' => true,
'logErrorDetails' => true,
'logger' => [
'name' => 'slim-app',
'path' => isset($_ENV['docker']) ? 'php://stdout' : __DIR__ . '/../logs/app.log',
'level' => Logger::DEBUG,
],
"db" =>
[
'driver' => 'pgsql',
'host' => 'localhost',
'port' => '5433',
'database' => 'test_db',
'username' => 'postgres',
'password' => 'password',
'prefix' => '',
'schema' => 'public',
]
]);
}
]);
};
Here is the code : (dependencies.php)
<?php
declare(strict_types=1);
use App\Application\Settings\SettingsInterface;
use DI\ContainerBuilder;
use Monolog\Handler\StreamHandler;
use Monolog\Logger;
use Monolog\Processor\UidProcessor;
use Psr\Container\ContainerInterface;
use Psr\Log\LoggerInterface;
return function (ContainerBuilder $containerBuilder) {
$containerBuilder->addDefinitions([
LoggerInterface::class => function (ContainerInterface $c) {
$settings = $c->get(SettingsInterface::class);
$loggerSettings = $settings->get('logger');
$logger = new Logger($loggerSettings['name']);
$processor = new UidProcessor();
$logger->pushProcessor($processor);
$handler = new StreamHandler($loggerSettings['path'], $loggerSettings['level']);
$logger->pushHandler($handler);
return $logger;
},
PDO::class => function (ContainerInterface $c)
{
$settings = $c->get(SettingsInterface::class);
$dbSettings = $settings->get("db");
$host = $dbSettings['host'];
$dbname = $dbSettings['database'];
$username = $dbSettings['username'];
$password = $dbSettings['password'];
$port = $dbSettings['port'];
$dsn = new PDO ("pgsql:host=$host;port=$port;dbname=$dbname");
return new PDO($dsn, $username, $password);
},
]);
};
Here checking for database connection : (routes.php)
<?php
declare(strict_types=1);
use App\Application\Actions\User\ListUsersAction;
use App\Application\Actions\User\ViewUserAction;
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\App;
use Slim\Interfaces\RouteCollectorProxyInterface as Group;
return function (App $app) {
$app->options('/{routes:.*}', function (Request $request, Response $response) {
// CORS Pre-Flight OPTIONS Request Handler
return $response;
});
$app->get('/', function (Request $request, Response $response) {
$response->getBody()->write('Hello world!');
return $response;
});
$app->group('/users', function (Group $group)
{
$group->get('', ListUsersAction::class);
$group->get('/{id}', ViewUserAction::class);
});
$app->post('/db-select', function (Request $request, Response $response)
{
$db = $this->get(PDO::class);
$sth = $db->prepare("SELECT * FROM login");
$sth->execute();
$data = $sth->fetchAll(PDO::FETCH_ASSOC);
$payload = json_encode($data);
$response->getBody()->write($payload);
return $response->withHeader('Content-Type', 'application/json');
});
};
If I run the command such as localhost:8000/db-select Its give me the following error:
{
"statusCode": 500,
"error": {
"type": "SERVER_ERROR",
"description": "SQLSTATE[08006] [7] fe_sendauth: no password supplied"
}
}
I worked the sample code for MYSQL it worked perfect.
What else missed for Postgresql connection?

Answer 1

Check extension for PostgreSQL is enabled
extension=pdo_pgsql
Also you may take help fromm this question
fe_sendauth: no password supplied error in postgresql + laravel

Answer 2

Here is a bug:
$dsn = new PDO ("pgsql:host=$host;port=$port;dbname=$dbname");
return new PDO($dsn, $username, $password);
Try this:
return new PDO("pgsql:host=$host;port=$port;dbname=$dbname", $username, $password);
