Ok. I want to put the authentication if any visitor want to visit the homepage so he\/she need to login first. I need to create a route for this. so modify config\/routes.php file like this:<\/p>\n
...\r\nreturn function (Application $app, MiddlewareFactory $factory, ContainerInterface $container) : void {\r\n    \/\/$app->get('\/', App\\Handler\\HomePageHandler::class, 'home');\r\n    $app->route('\/', [\r\n        \\Zend\\Expressive\\Authentication\\AuthenticationMiddleware::class,\r\n        App\\Handler\\HomePageHandler::class,\r\n    ], ['GET'], 'home');\r\n    ...\r\n};<\/pre>\n
comment the default home route then add a new route like above. If we refresh our browser for the homepage, it’d show this error:<\/p>\n
Service with name \"Zend\\Expressive\\Authentication\\AuthenticationMiddleware\" could not be created. Reason: AuthenticationInterface service is missing<\/pre>\n
we need to register ‘Zend\\Expressive\\Authentication\\AuthenticationInterface’ under ‘factories’ config in config\/autoload\/dependencies.global.php.:<\/p>\n
return [\r\n    ..\r\n    'dependencies' => [\r\n        ...\r\n        \/\/ Use 'factories' for services provided by callbacks\/factory classes.\r\n        'factories'  => [\r\n            \/\/ Fully\\Qualified\\ClassName::class => Fully\\Qualified\\FactoryName::class,\r\n            Zend\\Expressive\\Authentication\\AuthenticationInterface::class => Zend\\Expressive\\Authentication\\Session\\PhpSessionFactory::class\r\n        ],\r\n    ],\r\n];<\/pre>\n
If we refresh our browser again, it’d show another error:<\/p>\n
Service with name \"Zend\\Expressive\\Authentication\\AuthenticationInterface\" could not be created. Reason: UserRepositoryInterface service is missing for authentication<\/pre>\n
So I modify again config\/autoload\/dependencies.global.php to add ‘Zend\\Expressive\\Authentication\\UserRepositoryInterface’ class in ‘aliases’ config:<\/p>\n
return [\r\n   ...\r\n    'dependencies' => [\r\n        ...\r\n        'aliases' => [\r\n            \/\/ Fully\\Qualified\\ClassOrInterfaceName::class => Fully\\Qualified\\ClassName::class,\r\n            Zend\\Expressive\\Authentication\\UserRepositoryInterface::class => Zend\\Expressive\\Authentication\\UserRepository\\PdoDatabase::class\r\n        ],\r\n       ...\r\n    ],\r\n];\r\n<\/pre>\n
When I refresh the browser again. This error would be appear:<\/p>\n
Service with name \"Zend\\Expressive\\Authentication\\AuthenticationInterface\" could not be created. Reason: The redirect configuration is missing for authentication<\/pre>\n
So I need to put my database credentials to connect zend expressive to mysql database in config\/autoload\/local.php file (if this file not exist, please create one):<\/p>\n
return [\r\n    'authentication' => [\r\n        'pdo' => [\r\n            'dsn'   => 'mysql:host=localhost;dbname=expressive',\r\n            'username' => 'your-mysql-username',\r\n            'password' => ''your-mysql-password',\r\n            'table' => 'users',\r\n            'field' => [\r\n                'identity' => 'username',\r\n                'password' => 'password',\r\n            ],\r\n        ],\r\n        'redirect' => '\/login',\r\n    ],\r\n];<\/pre>\n
Please create a new database ‘expressive’ and a new table ‘users’ first. The users table consist of only two fields now. There are username (varchar 100) and password (varchar 100). I put ‘redirect’ value to ‘\/login’ so it’d redirect the homepage to login page. Make sure the credentials is correct. If not you’d get an error like this:<\/p>\n
Service with name \"Zend\\Expressive\\Authentication\\UserRepository\\PdoDatabase\" could not be created. Reason: SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO)<\/pre>\n
Then I refresh my browser again. Another error is coming up:<\/p>\n
Request is missing the attribute Zend\\Expressive\\Session\\SessionMiddleware::SESSION_ATTRIBUTE (\"session\"); perhaps you forgot to inject the Zend\\Expressive\\Session\\SessionMiddleware prior to the Zend\\Expressive\\Authentication\\AuthenticationMiddleware?<\/pre>\n
Here we need ‘Zend\\Expressive\\Session\\SessionMiddleware’ class before routing middleware. So add it in config\/pipeline.php:<\/p>\n
return function (Application $app, MiddlewareFactory $factory, ContainerInterface $container) : void {\r\n    ...\r\n\r\n    $app->pipe(\\Zend\\Expressive\\Session\\SessionMiddleware::class);\r\n\r\n    \/\/ Register the routing middleware in the middleware pipeline.\r\n    \/\/ This middleware registers the Zend\\Expressive\\Router\\RouteResult request attribute.\r\n    $app->pipe(RouteMiddleware::class);\r\n\r\n    ...\r\n};<\/pre>\n
We fixed those errors until here. When we refresh our browser, we’d get the login page. But the content is showing 404 because we haven’t defined the login page!\"\"<\/a>Create the login form. Add a new file ‘LoginForm.php’ in ‘src\/App\/Form’ directory. The login form will show username and password fields. The post the form, I’ll put a submit button:<\/p>\n
<?php\r\ndeclare(strict_types=1);\r\nnamespace App\\Form;\r\n\r\nuse Zend\\Form\\Form;\r\nuse Zend\\InputFilter\\InputFilterProviderInterface;\r\nuse Zend\\Form\\Element\\Text;\r\nuse Zend\\Form\\Element\\Password;\r\n\r\nclass LoginForm extends Form implements InputFilterProviderInterface\r\n{\r\n    public function __construct()\r\n    {\r\n        parent::__construct('login-form');\r\n    }\r\n\r\n    public function init()\r\n    {\r\n        $this->add([\r\n            'type' => Text::class,\r\n            'name' => 'username',\r\n            'options' => [\r\n                'label' => 'Username',\r\n            ],\r\n        ]);\r\n \r\n        $this->add([\r\n            'type' => Password::class,\r\n            'name' => 'password',\r\n            'options' => [\r\n                'label' => 'Password',\r\n            ],\r\n        ]);\r\n \r\n        $this->add([\r\n            'name' => 'Login',\r\n            'type' => 'submit',\r\n            'attributes' => [\r\n                'value' => 'Login',\r\n            ],\r\n        ]);\r\n    }\r\n\r\n    public function getInputFilterSpecification()\r\n    {\r\n        return [\r\n            [\r\n                'name' => 'username',\r\n                'required' => true,\r\n                'filters' => [\r\n                    ['name' => 'StripTags'],\r\n                    ['name' => 'StringTrim'],\r\n                  ],\r\n            ],\r\n \r\n            [\r\n                'name' => 'password',\r\n                'required' => true,\r\n                'filters' => [\r\n                    ['name' => 'StripTags'],\r\n                    ['name' => 'StringTrim'],\r\n                ],\r\n            ],\r\n        ];\r\n    }\r\n}\r\n<\/pre>\n
then create a login page handler with inject it with login form with the following factory in src\/App\/Handler\/LoginPageFactory.php:<\/p>\n
<?php\r\ndeclare(strict_types=1);\r\n\r\nnamespace App\\Handler;\r\n\r\nuse Psr\\Container\\ContainerInterface;\r\nuse Psr\\Http\\Server\\MiddlewareInterface;\r\nuse Zend\\Expressive\\Template\\TemplateRendererInterface;\r\nuse Zend\\Form\\FormElementManager;\r\nuse App\\Form\\LoginForm;\r\n\r\nclass LoginPageFactory\r\n{\r\n    public function __invoke(ContainerInterface $container) : MiddlewareInterface\r\n    {\r\n        $template = $container->get(TemplateRendererInterface::class);\r\n        $loginForm = $container->get(FormElementManager::class)->get(LoginForm::class);\r\n\r\n        return new LoginPageHandler($template, $loginForm);\r\n    }\r\n}\r\n<\/pre>\n
The LoginPageHandler itself can be initialized in src\/App\/Handler\/LoginPageHandler.php:<\/p>\n
<?php\r\ndeclare(strict_types=1);\r\n\r\nnamespace App\\Handler;\r\n\r\nuse Psr\\Http\\Server\\MiddlewareInterface;\r\nuse Zend\\Expressive\\Template\\TemplateRendererInterface;\r\nuse App\\Form\\LoginForm;\r\nuse Psr\\Http\\Message\\ServerRequestInterface;\r\nuse Psr\\Http\\Server\\RequestHandlerInterface;\r\nuse Psr\\Http\\Message\\ResponseInterface;\r\nuse Zend\\Expressive\\Session\\SessionMiddleware;\r\nuse Zend\\Expressive\\Authentication\\UserInterface;\r\nuse Zend\\Diactoros\\Response\\RedirectResponse;\r\nuse Zend\\Diactoros\\Response\\HtmlResponse;\r\n\r\nclass LoginPageHandler implements MiddlewareInterface\r\n{\r\n    private $template;\r\n    private $loginForm;\r\n\r\n    public function __construct(\r\n        TemplateRendererInterface   $template,\r\n        LoginForm                   $loginForm\r\n    )\r\n    {\r\n        $this->template = $template;\r\n        $this->loginForm = $loginForm;\r\n    }\r\n\r\n    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface\r\n    {\r\n        $session = $request->getAttribute(SessionMiddleware::SESSION_ATTRIBUTE);\r\n        if ($session->has(UserInterface::class)) {\r\n            return new RedirectResponse('\/');\r\n        }\r\n\r\n        $error = '';\r\n\r\n        return new HtmlResponse(\r\n            $this->template->render('app::login-page', [\r\n                'form' => $this->loginForm,\r\n                'error' => $error,\r\n            ])\r\n        );\r\n    }\r\n}\r\n<\/pre>\n
Above, we redirect to ‘\/’ page when there is a session data as it already authenticated check. We are going to add authentication process next.<\/p>\n
The Login form can be as simple as the following in templates\/app\/login-page.phtml<\/p>\n
<?php\r\n\r\necho $error;\r\n\r\n$form->prepare();\r\n\r\necho $this->form($form);<\/pre>\n
We can register the LoginPageHandler at App\\ConfigProvider::getDependencies() config in src\/App\/ConfigProvider.php<\/p>\n
...\r\nclass ConfigProvider\r\n{\r\n    ...\r\n\r\n    \/**\r\n     * Returns the container dependencies\r\n     *\/\r\n    public function getDependencies() : array\r\n    {\r\n        return [\r\n            'invokables' => [\r\n                ...\r\n            ],\r\n            'factories'  => [\r\n                Handler\\HomePageHandler::class => Handler\\HomePageHandlerFactory::class,\r\n                Handler\\LoginPageHandler::class => Handler\\LoginPageFactory::class,\r\n            ],\r\n        ];\r\n    }\r\n\r\n    ...\r\n}\r\n<\/pre>\n
The routing can be registered as follows with add \\Zend\\Expressive\\Authentication\\AuthenticationMiddleware::class for next middleware in config\/routes.php:<\/p>\n
return function (Application $app, MiddlewareFactory $factory, ContainerInterface $container) : void {\r\n    ...\r\n\r\n    $app->route('\/login', [\r\n        App\\Handler\\LoginPageHandler::class,\r\n        \\Zend\\Expressive\\Authentication\\AuthenticationMiddleware::class,\r\n    ], ['GET', 'POST'], 'login');\r\n    \r\n    ...\r\n};<\/pre>\n
Until this, when I refresh the browser, I got this error and can’t continue anymore. I still dont know why the error is happened:<\/p>\n
