Slim-3 php框架即使网址正确也显示页面未找到错误？

Question

Slim-3 php框架显示页面未找到错误，即使网址正确也是如此。 我正在使用slim3框架在php中为android应用程序编写网络服务。 几天前它无法正常工作。相同的代码现在无法正常工作。它始终返回未找到的页面。我认为index.php文件中存在错误，但我无法弄清楚。

我已经尽力解决此问题。 我更改了目录结构和.htaccess文件，但仍未解决。我正在使用xampp服务器。

index.php

<?php

use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;


require '../ChickenShop/vendor/autoload.php';
require_once '../ChickenShop/public/includes/DbOperations.php';


//Creating a new app with the config to show errors
 $app = new \Slim\App([
    'settings' => [
        'displayErrorDetails' => true
    ]
]);


//registering a new user
$app->post('/register', function (Request $request, Response $response) {
    if (isTheseParametersAvailable(array('name', 'email', 'password', 'phone','address'))) {
        $requestData = $request->getParsedBody();
        $name = $requestData['name'];
        $email = $requestData['email'];
        $password = $requestData['password'];
        $phone = $requestData['phone'];
        $address = $requestData['address'];
        $db = new DbOperations();
        $responseData = array();

        $result = $db->registerUser($name, $email, $password, $phone, $address);

        if ($result == USER_CREATED) {
            $responseData['error'] = false;
            $responseData['message'] = 'Registered successfully';
            $responseData['user'] = $db->getUserByEmail($email);
        } elseif ($result == USER_CREATION_FAILED) {
            $responseData['error'] = true;
            $responseData['message'] = 'Some error occurred';
        } elseif ($result == USER_EXIST) {
            $responseData['error'] = true;
            $responseData['message'] = 'This email already exist, please login';
        }

        $response->getBody()->write(json_encode($responseData));
    }
});


//user login route
$app->post('/login', function (Request $request, Response $response) {
    if (isTheseParametersAvailable(array('email', 'password'))) {
        $requestData = $request->getParsedBody();
        $email = $requestData['email'];
        $password = $requestData['password'];

        $db = new DbOperations();

        $responseData = array();

        if ($db->userLogin($email, $password)) {
            $responseData['error'] = false;
            $responseData['user'] = $db->getUserByEmail($email);
        } else {
            $responseData['error'] = true;
            $responseData['message'] = 'Invalid email or password';
        }

        $response->getBody()->write(json_encode($responseData));
    }
});

//getting all products
$app->get('/products', function (Request $request, Response $response) {
    $db = new DbOperations();
    $products = $db->getAllProducts();
    $response->getBody()->write(json_encode(array("products" => $products)));
});

//function to check parameters
function isTheseParametersAvailable($required_fields)
{
    $error = false;
    $error_fields = "";
    $request_params = $_REQUEST;

    foreach ($required_fields as $field) {
        if (!isset($request_params[$field]) || strlen(trim($request_params[$field])) <= 0) {
            $error = true;
            $error_fields .= $field . ', ';
        }
    }

    if ($error) {
        $response = array();
        $response["error"] = true;
        $response["message"] = 'Required field(s) ' . substr($error_fields, 0, -2) . ' is missing or empty';
        echo json_encode($response);
        return false;
    }
    return true;
}

// Run app
$app->run();

我尝试访问的URL：

http://localhost/ChickenShop/public/

Content of .htaccess file:



        RewriteEngine On
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^ index.php [QSA,L]

我希望它能正常工作。
