Windwalker application is a kernel as main entry of your system.
Add this to the require block in your composer.json.
{
"require": {
"windwalker/application": "~3.0"
}
}Create application and extends the doExecute() method to something.
use Windwalker\Application\AbstractApplication;
use Windwalker\IO\Input;
use Windwalker\Structure\Structure;
class MyApplication extends AbstractApplication
{
protected function init()
{
// Do stuff.
// Get config
$this->get('foo'); // bar
}
public function doExecute()
{
try
{
// Some code here...
}
catch (\Exception $e)
{
Error::renderErrorPage();
}
return true;
}
}
$app = new MyApplication(new Structure(array('foo' => 'bar')));
$app->execute();Config is Structure object, see Windwalker Structure
AbstractWebApplication contains WebEnvironment and WenHttpServer object that help us handle HTTP request and output.
Use WebEnvironment to get information of browser or server.
$this->environment->browser->getBrowser(); // Get browser nameUse Platform to get server information.
$this->environment->platform->isUnix();See: Environment Package
dispatch() is a standard PSR7 handler so we can write our logic here, just return Response object and the WebHttpServer
object which in Application will render it to client.
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Windwalker\Application\AbstractWebApplication;
class MyHttpKernel extends AbstractWebApplication
{
public function dispatch(Request $request, Response $response, $next = null)
{
// Get request query
$query = $request->getQueryParams();
// Get Psr Uri
$uri = $request->getUri();
// Write body
$response->getBody()->write('<h1>Hello World~~~!</h1>');
return $response;
}
}
$app = new MyHttpKernel;
$app->execute();Result:
<h1>Hello World~~~!</h1>Set error handler as final handler so we can use it in dispatch().
class MyHttpKernel extends AbstractWebApplication
{
public function dispatch(Request $request, Response $response, $next = null)
{
try
{
throw new \Exception('Whoops~', 500);
}
catch (\Exception $e)
{
return $next($e, $request, $response);
}
return $response;
}
}
$app = new MyHttpKernel;
$app->setFinalHandler(function (Exception $e, Request $request, Response $response)
{
$response->getBody()->write(sprintf('<h1>Error %s. Message: %s</h1>', $e->getCode(), $e->getMessage()));
});
$app->execute();Result:
<h1>Error 500. Message: Whoops~</h1>This is a example of a simple cli application.
// app.php
use Windwalker\Application\AbstractCliApplication;
class MyCliApp extends AbstractCliApplication
{
public function doExecute()
{
// Get options (-h)
$help = $this->io->get('h');
if ($help)
{
$msg = <<<MSG
Help message: version 1.0
------------------------------------
myapp.php <command> [-options]
foo Description of this command.
bar Description of this command.
help Description of this command.
MSG;
$this->io->out($msg);
$this->close();
}
// Get arguments
$arg = $this->getArgument(0);
// Do some stuff...
return 0; // Exit code 0 means success
}
}
$app = new MyCliApp;
$app->execute();Now we can access this app by PHP CLI:
php app.php arg1 arg2 -h --option --foo bar --n=aSee: Windwalker IO
