苗条的应用程序错误数据库

Slim Application Error DB

我是 Restful API 的新手。我正在尝试制作自己的以下 Internet 教程。 为此 API 我正在使用 Slim PHP 框架。

我已经创建了 db.php(配置文件):

<?php
class db {
    //properties
    private $dbhost = 'localhost';
    private $dbuser = 'root';
    private $dbpass = '';
    private $dbname = 'slimapi';

    //Connect
    public function connect() {
        $mysql_connect_str = "mysql:host=$this->dbhost;dbname=$this->dbname";
        $dbConnection = new PDO($mysql_connect_str, $this->dbuser, $this->dbpass);
        $dbConnection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        return $dbConnection;
    }
}

然后我得到了我的 paciente.php(我正在尝试将数据提取到的位置):

<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

$app = new \Slim\App;

//Get All Pacientes
$app->get('/api/pacientes', function (Request $request, Response $response) {
    $sql = "SELECT * FROM pacientes";

    try {
        //GET DB Object
        $db = new db();
        //Connect
        $db = $db->connect();

        $stmt = $db->query($sql);
        $pacientes = $stmt->fetchAll(PDO::FETCH_OBJECT);
        $db = null;
        echo json_encode($pacientes);

    } catch(PDOException $e) {
        echo '{"error": {"text": '.$e->getMessage().'}';
    }
});

我在尝试加载 /api/pacientes 时遇到 this 错误:

Slim Application Error A website error has occurred. Sorry for the temporary inconvenience.

我已经测试了与数据库的连接,没问题。 我可能在配置文件 (db.php) 上做错了,但我知道。 感谢大家的阅读和回答!

编辑: 如果需要,请添加我的 index.php:

    <?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

require '../vendor/autoload.php';
require '../src/config/db.php';

$app = new \Slim\App;
$app->get('/hello/{name}', function (Request $request, Response $response, array $args) {
    $name = $args['name'];
    $response->getBody()->write("Hello, $name");

    return $response;
});

//Pacientes Routes
require '../src/routes/pacientes.php';

$app->run();

这是一个错字: pacientes.php

上的第 18 行
    $pacientes = $stmt->fetchAll(**PDO::FETCH_OBJECT**);

必须是

    $pacientes = $stmt->fetchAll(***PDO::FETCH_OBJ***);
